Tutorial
The following documentation is quite long. If you don't want to read through it, here is the quick start:
- install
SQL Workbench/J
from here - install your
jdbc
driver for your database see here - set
SQL Workbench/J
to not useJLine
(inSQL Workbench/J
config file, add the following line:workbench.console.use.jline=false
) - open vim
Running sql queries against a DBMS:
- set the
g:sw_config_dir
,g:sw_exe
andg:sw_cache
variables - for
cygwin
environments, please also set theg:sw_plugin_path
variable (this should point to the installation directory of the plugin). For example:c:/Users/cosmin/.vim/bundle/vim-sql-workbench
- open your sql buffer
- if you have
CtrlP
installed you can doCtrlP
and then selectSQL Workbench profiles
and choose your profile - otherwise, you can do
:SWSqlBufferConnect
and then in the buffer executeWbConnect
(<Leader>C-<SPACE>
) - go to an sql statement
- in normal mode, do
<Leader><C-SPACE>
Opening a database explorer
:SWDbExplorer <my-profile>
Note:
<my-profile>
is the name of a database profile created inSQL Workbench/J
(see here)
For more detailed explanations, please continue reading this material.
Disclaimer
Please note that this version is no longer compatible with VIM 7. If you
didn't upgraded to VIM 8 yet, then don't install this version. Stick with
5.2.2. But you should consider upgrading your vim anyway. For the
documentation of 5.2.2
, please see here
Introduction
This is an implementation of SQL Workbench/J
in VIM. It works with any DBMS supported by SQL Workbench/J
(PostgreSQL,
Oracle, SQLite, MySQL, SQL Server etc.). See the complete list
here.
You can connect to any DBMS directly from VIM.
Features:
- database explorer (e.g.: table lists, procedures list, views list, triggers list), extensible (you can have your own objects list)
- SQL buffer with very powerfull intellisense auto-completion
- export any sql statement as
text
,sqlinsert
,sqlupdate
,sqldeleteinsert
,xml
,ods
,html
,json
- search in object source
- search in table or views data
- asynchronous (you can execute any command asynchronous)
- fully customizable
- transactions
- NeoVim 100% support

Requirements
Vim 8
SQL Workbench/J
installed on the machine
NOTE: this version of vim-sql-workbench
is not compatible with vim 7 anymore.
Of course you need VIM 8 or above. You also need SQL Workbench/J
installed on your computer. It is
platform independent, since SQL Workbench
is written in JAVA and it should
work anywhere where VIM works.
Before getting started, you have to set the g:sw_exe
vim variable. The
default value is sqlwbconsole.sh
. Otherwise, just set the value of the
variable to point to your sqlwbconsole
file. If you are on Windows, it
should be sqlwbconsole.exe
.
Also, if you are on Windows, you have to set the g:sw_tmp
value in your
vimrc
. The default value is /tmp
.
If you are on window, your SQL Workbench/J
should be configured to not use
the jline
(set the workbench.console.use.jline=false
in your SQL Workbench/J
config file).
Connecting to a DBMS
VIM Sql workbench
has integration with the CtrlP
plugin. You can set the
g:sw_config_dir
variable (which contains the WbProfiles.xml
file) and then
you open your buffer, open CtrlP
, select SQL Workbench profiles
, select
your profile and you can begin sending sql queries to your database.
If you don't have CtrlP
installed, you can use the :SWSqlBufferConnect
command. This will open your buffer and connect it to the SQL Workbench/J
.
If you run it without any arguments, the current buffer will be connected with
a SQL workbench/J
instance.
Example:
:SWSqlBufferConnect ~/Documents/my-buffer.sql
Once you connected your buffer (either by CtrlP
or by using
SWSqlBufferConnect
), a new sqlwbconsole.sh
process will be launched. This
will have it's own connection and it's own transaction. If you close the
buffer, also the process will be closed. Also, if you do
:SWSqlBufferDisconnect
, the sqlwbconsole
instance will be closed.
The database explorer
In order to open a database explorer, you need a profile.
You can create SQL Workbench
profiles, either by using the SQL Workbench
GUI, like
here,
either opening a sql buffer with SWSqlBufferConnect
and then executing
WbStoreProfile
.
Once you have your profiles created, you can use SWDbExplorer
with the
desired profile as argument and you will connect to the database.
For example, :SWDbExplorer myProfile
will open a database explorer using the
profile myProfile
.
The database explorer is composed from three parts: on the top, there is a list of available shortcuts at any moment. On the bottom left, you will see the list of objects in your database (the list of tables and views or the list of procedures or the list of triggers etc.) and on the bottom right, you will see the selected object desired properties. Like in the second or third screen shot.
So, if you want to see the columns of a table, you will have to move the cursor in the bottom left panel, go to the desired table and press 'C'. This will display in the right panel the table columns, indices and triggers. If you want to see its source code, you press 'S' and so on. For all the available shortcuts, see the top panel.
The database explorer if fully customizable. You can use the existing one and extend it or you can create your own from scratch.
Creating a new database explorer from scratch
The database explorer is loaded from the resources/dbexplorer.vim
file by
default. If you want to write your own, set the g:sw_dbexplorer_panel
variable to point to your own file and that file will be loaded. The file has
to be a vimscript
file, since it's going to be sourced and it needs to set
the g:SW_Tabs
variable. For an example, take a look at the
resources/dbexplorer.vim
file.
The g:SW_Tabs
has to be a vim dictionary. The keys are the profiles for
which the panel will be applied. *
profile, means that the options appear on
all profiles. If you want to have separate database explorers for separate
profiles, you can create a key in the dictionary for each explorer.
You can also have profiles per type of DBMS. If you have a profile starting
with a :
or a '^'.
A :
means that this options will appear for all the profiles which the DBMS
is of that type. For example :MySQL
it means that these options will appear
only for mysql
databases.
A ^
means that this options will appear for all the profiles for which the
DBMS is not of that type. For example ^PostgreSQL
means that there options
will appear for all databases which are not PostgreSQL
.
For this to work, you have to have the option g:sw_config_dir
set. The
profile informations are read from the WbProfiles.xml
file which resides in
this folder. The profile type you can see it in the SQL Workbench/J
connection window. It's the driver title.
Starting with version 4.0
you can also have a vimscript function called
instead of a sql query. The function called has to return a string which will
be interpreted as the result of the operation. The function will receive as
parameters the line selected (the complete line which has been selected). In
order to have a function instead of a sql query in the database explorer, the
command
has to begin with :
.
For example:
{'title': 'Data', 'shortcut': 'D', 'command': ':My_function'}
When the shortcut D will be pressed, the result will be fetch by calling
My_function(getline('.'))
Of course, the current line is relevant only for when changing a tab. When changing a tab, the current line will contain whatever value is on the current line in whatever buffer you are at that moment.
The values for each profile, have to be a list which will contain all the options for the left panel. For example, in the default one, the database objects, triggers and procedures.
Each list of objects of this list is another dictionary, with the following keys:
title
(the title which will be displayed in the top panel)shortcut
(the shortcut to access it; please note that you can have several letters)command
(the sql command which will be executed when selecting the object)panels
(a list of options accessible in the right panel for each selected object in the left panel)
The panels are also a list of dictionaries. Each element of the list has the following keys:
title
(the title which will be displayed in the top panel)shortcut
(the shortcut which will be used to display it)command
(the sql command which will be executed; please note that the sql command should contain the%object%
string, which will be replaced with the name of the selected object)
Optional, the panels might contain the following keys:
skip_columns
(a list with the column indices from the result set that should not be displayed)hide_header
(if set andtrue
, then the header of the result set will not be displayed in the bottom right panel)filetype
(if present, the bottom right panelfiletype
will be set according when selecting an object in the left panel)
NOTES:
- In the command that creates the left panel, the object for which you want
to select the informations in the right panel should always be on the first
column. The
%object%
string in the column will be replaced by it. Alternatively, you can have%n%
(n being a number from 0 to the number of columns in the left panel). If you have%n%
, this will be replaced by the value of that column - The command can contain a comment in the format
-- AFTER
at the end. Everything following "AFTER" word will be interpreted as a VIM command and will be executed after the result has been displayed in the right panel. For an example, see the SQL Source panel in the default database explorer vim file (resources/dbexplorer.vim
). - The shortcuts for the left panel (the list of objects) have to be unique. They are used to identify the current option selected to be displayed, so that the shourtcuts for the left panel are loaded according to the panels. However, the shortcuts for the right panel can be the same from one list of objects to the other. For example, you can have "O" as shortcut for objects list and then for each object you can have "S" for showing the source code. Then, you can have "P" for listing the procedures. Again, for each procedure you can have again "S" as shortcut for listing the source code of a procedure or for something else.
Extending the default database explorer
If you are happy with the default options of the database explorer (which are
the same with the ones of SQL Workbench/J
) but you just want to add your
own, you can do so by extending the default database explorer.
This is done by calling the vimscript
function sw#dbexplorer#add_tab
. The
function takes the following arguments:
- The profile (the profile for which the option should be active; it can be
*
for all profiles) - The title (this is the title that will appear on the top panel)
- The shortcut (this is the shortcut to access it)
- The command (this is the SQL command to be sent to the DBMS once this option is selected)
- The list of panels (the list of properties to be displayed in the bottom right split for each object from the list)
The list of panels is an array of dictionaries. Each dictionary has the same
keys as indicated in the previous section for the list of panels. For example,
if you want to add the database links for all the profiles, you have to add
this in your vimrc
:
call sw#dbexplorer#add_tab('oracle', 'DB Links', 'L', 'select db_link, username,
created from user_db_links;', [{'title': 'Show the host', 'shortcut': 'H',
'command': "select host from user_db_links where db_link = '%object%'"}])
Now on all your oracle profiles, you will have an extra option. Every time when you click "L" in normal mode, in the bottom left panel you will have a list of database links from your schema. For each link, you can move the cursor on top of it and click H. You will see in the right panel the source of the link.
Every time when "L" is clicked, vim-sqlworkbench
sends the select db_link, username, created from user_db_links;
command to the DBMS. The result will be
a list of database links displayed in the bottom left panel. When you move
your cursor on top of one of this links and press "H", the plugin sends to
your DBMS select host from user_db_links where db_link = '<selected_link_name>';
. The result is displayed in the right panel.
You can also add a panel to an existing tab, using the
sw#dbexplorer#add_panel
function. The function takes the following arguments:
- The profile (the profile for which the option should be active; it can be
*
for all profiles) - The tab shortcut (is the shortcut identifying the tab for which to add this panel)
- The title (this is the title that will appear on the top panel)
- The shortcut (this is the shortcut to access it after you accessed the tab)
- The command (this is the SQL command to be sent to the DBMS once this option is selected
Events
The database explorer has events to which you can hook a function to be executed before the command is executed or after the result is received. If you hook to the before event, your function will receive as a parameter the command being set to a server and it must return the modified command. If you hoon to the after event, your function will receive the response from the server (an array of lines) and can modify it. It has to return the result which will be displayed in the left or right panel (a new list of lines).
To hook on the tab events, you can use the function
sw#dbexplorer#add_tab_event
. The arguments are:
- the shortcut of the tab
- the event type (
after
orbefore
) - the function name
Example:
function! BeforeTabObjects(command)
return "show tables"
endfunction
function! AfterTabObjects(result)
let result = []
for line in a:result
call add(result, substitute(line, '\v^TABLE_NAME[ \s\t]*$', 'Tables', 'g'))
endfor
return result
endfunction
call sw#dbexplorer#add_tab_event('O', 'before', 'BeforeTabObjects')
call sw#dbexplorer#add_tab_event('O', 'after', 'AfterTabObjects')
After executing this example, when you select the Objects tab in the database
explorer, the command executed is going to be show tables
, instead of
WbList
, which is the default for objects. Then, when the result is returned,
the line TABLE_NAME
is going to be replaces with the text "Tables".
To hook on panel events, you can use the function
sw#dbexplorer#add_panel_event
. The arguments are:
- the shortcut of the tab
- the shortcut of the panel
- the type of event (
after
orbefore
) - the function name
For an example on how to use this function, see the resources/dbexplorer.vim
file (the last line) and the autoload/sw/dbexplorer.vim
file to see the
function hook definition.
The SQL buffer
The SQL buffer is a normal vim
buffer from which you can send SQL commands
to your DBMS and in which you can use the user completion (<C-x><C-o>) to have
intellisense autocompletion.
You can connect an opened vim buffer to a server using the
SWSqlBufferConnect
command. Or, you can open a buffer which will be directly
connected to a server by specifying the path to the buffer. For example
SWSqlBufferDisconnect /tmp/dbms.sql
.
Once in an sql buffer, you have several ways to execute commands against your DBMS:
- execute the current SQL
- execute the selected statement
- execute all statements
All the shortcuts for these commands are fully customizable. But to do this,
you cannot just map the commands in vimrc
. This is because these shortcuts
are mapped local to the sql buffer, or to the result sets buffer. If you want
to change the default shortcuts, you need to define the
g:sw_shortcuts_sql_buffer_statement
variable or the
g:sw_shortcuts_sql_results
variable. This variables should point each to a
vimscript
file which will define the mappings.
The g:sw_shortcuts_sql_buffer_statement
variable is used for the sql buffer
itself, while the g:sw_shortcuts_sql_results
variable is used for the result
set buffer (see the 4th scren shot).
As soon as a SQL buffer is opened the shortcuts from the
g:sw_shortcuts_sql_buffer_statement
will be mapped. If the variable is not
set, then the resources/shortcuts_sql_buffer_statement.vim
file is loaded.
So, have a look at this file for further details. Please note that for
executing the current SQL, the default shortcut is <leader>ctrl + space
.
The same goes for a result set buffer. The shortcuts from the file pointed by
the g:sw_shortcuts_sql_results
variable are loaded. If the variable is not
set, then the shortcuts from resources/shortcuts_sql_results.vim
are loaded.
If you want further details, please have a look at this file.
You can also have comment in the format -- before <command>
on a single
line. This comments will be parsed by the plugin. If the command begins with a
:
it will be interpreted as a vim
command and executed by vim. Otherwise,
the command will be sent to the DBMS when opening the file.
Examples:
-- before start transaction;
This command will be sent to the DBMS and will start a new transaction every time when you open this buffer.
Execute the current statement
As stated already, you can press <leader>ctrl + space
in normal mode or
you can have your own shortcut. Alternatively, in normal mode, you can execute
SWSqlExecuteCurrent
command.
The statement between the last 2 delimiters will be sent to the server, or from the beginning of the file until the first delimiter, or from the last delimiter to the end of the file, depending on where your cursor is placed.
Execute the selected statement
In visual mode, you can press <leader>ctrl + e
or your own custom shortcut.
Alternatively, you can execute the SWSqlExecuteSelected
command. Please be
careful to delete the range before, if you want to execute the command from
the visual mode.
The selected text is going to be sent to the DBMS.
Execute all statements
In visual mode, you can press <leader>ctrl + a
or your own custom shortcut.
Alternatively, you can execute the SWSqlExecuteAll
command. All the buffer
is going to be sent to the DBMS.
Events
The following events exist in the plugin:
new_instance
(triggered when a new instance ofSQL Workbench/J
is spawned).profile_changed
(triggered every time a connection to a new profile is detected)
In order to attach a hook to an event, you have to call sw#server#add_event
with 2 arguments: the event name and the event listener. For an example, check
the plugin/sw.vim
file in the source code.
Schema report
SQL Workbench/J
has the ability to generate a very usefull schema report.
This report is used by the autocomplete intellisense and by references tree.
If you want to have intellisense for a profile, in the GUI of SQL Workbench/J
profiles page, add the extended property report
with the value
true
(see
here).
The report is going to be generated using a paralel background connection.
This means that the current connection will not have to suffer if the report
generation will take too long (depending on your database size, this can even
take several minutes).
It is very usefull to have this report. Other than intellisense, you can also
see in the db explorer the dependencies tree (Referenced by
and References
options).
Please note that the intellisense and the references tree will not work without this report.
If you have schemas with the same structure from one profile to another you
don't have to generate the report for all the profiles. You can generate it
from one profile (usually dev
or test
) and for the rest of the profiles
you can set the extended property use-report
with the value of the other
profile name, including the group.
So, for example, if you have the profiles dev
in the group LOCAL
and
prod
, which are basically identically, you might not want to run the schema
report on prod. So, you set the extended property report
with the value
true
for the dev
profile and the extended property use-report
with the
value LOCAL\dev
. Like this, every time when you connect to the dev
profile, a new connection will be spawned in the background which will
generate the schema report. Once this is generated at least once, you have
intellisense and references tree available. And every time you connect to the
prod
profile, you always have the same intellisense autocomplete and the
references tree.
Intellisense
vim-sql-workbench
plugin comes with intellisense out of the box. In order to
take advantage of the auto complete intellisense, you have to set the schema
report (see the previous section).
If the schema report is available (either by setting the report
option or by
setting the use-report
option) you can press <C-x><C-u> in insert
mode in a sql statement.
Note: due to constant conflicts with dbext plugin (which apparently has some
parts included in the /usr/share/vim
folder) I prefer to switch to
<C-x><C-u>. So, you cannot use <C-x><C-o> anymore for
intellisense
The plugin will try to determine where you are in the sql and return the
appropriate options. For example, if you are in the fields part of a select
statement, the options returned will be the fields based on the tables from
the from
part of the select
. If you are in the from
part, then the list
of tables is returned. If you have an identifier followed by a dot, then if
that identifier is a table, a view or an alias of a view or subquery, the
system will return the corresponding list of fields.
Also the subqueries are parsed and the appropriate fields are returned.
If you are in a subquery in a bigger query, the auto complete will be executed at the level of the subquery.
If you are in a union
select
statement, the system will try to determine
in which select
the cursor is placed and execute auto completion for that sql.
NOTE: The autocomplete feature is implemented using regular expressions. Because of using regular expressions, it's possible that I've missed cases. If you notice any case where the autocomplete is not working properly, please let me know.
Get an object definition
When with the cursor on top of any word in the buffer or in the result set,
you can click <leader>oi
or your own custom shortcut. This will display that
object definition if the object exists in the result set buffer or an error
message.
Alternatively you can execute the SWSqlObjectInfo
command from normal mode.
Basically the command desc <object>
is sent to the DBMS and the output
returned.
Get an object source
When you are with the cursor on top of any word in the buffer or in the result
set, you can click <leader>os
or your own custom shortcut. This will display
the object source if the object exists in the result set buffer or an error
message.
Alternatively, you can execute the SWSqlObjectSource
command from normal
mode.
Maximum number of rows.
By default, the maximum number of results returned by a select is 5000. You
can change this with the set maxrows
command. See
here
Changing result sets display mode
In the result set buffer, you can click <leader>d
or your own custom shortcut
on top of a row. This will toggle the row display to have each column on a row
for the selected row. To change back the display mode, click again the same
shortcut.
Alternatively, you can execute the WbDisplay
command. See
here for more detail.
Filtering the resultset
While in the result window, you can filter the displayed rows. With the cursor
on a resultset, you can just call the SWSqlFilter
command with the where
condition as parameter. The plugin will send the query to the dbms
and
display the results in the same resultset.
Hiding columns
While in a result window, you can hide columns from a result set.
With the cursor on a resultset, you can call the SWSqlHideColumn
command.
The command takes as an argument the name of the column to hide (there is also
an autocomplete with the available columns).
Example: SWSqlHideColumn last_name
CtrlP integration
VIM Sql workbench
provides integration with the CtrlP
plugin. In order to
activate it, you need to set the g:sw_config_dir
option to point to your
SQL Workbench/J
configuration directory. Then, in your .vimrc
file, you
need to activate the CtrlP
extension sw_profiles
, by setting the
g:ctrlp_extensions
variable.
By activating the integration, you can change a buffer connection with
CtrlP
. You activate CtrlP
and then select the SQL Workbench profiles
tab
and select your profile. If the buffer is already connected to an SQL Workbench/J
instance, then the current connection will be changed. If no,
then the buffer will get connected to an SQL Workbench/J
instance and also
open a connection to the selected profile.
Airline integration
VIM Sql workbench
also provides integration with VIM Airline
plugin. Since I haven't
really found out how to create an extension and place it in any folder, you
will have to manually copy the resources/airline/sw.vim
file into the
Airline
extensions folder. Then you need to enable the extension in your
.vimrc
file by setting the g:airline_extensions
variable to include the
sw
extension.
Once you activate the integration, every time when you connect a buffer to an
SQL Workbench/J
instance, you will see the in the status bar the current
url (next to the file name). If the buffer is connected to SQL Workbench/J
,
but is not connected to a DBMS, then you will see the NOT CONNECTED
string.
Alternatively, if you don't use Airline integration, you can still see the
current url in the status line by activating the status line in vim (set laststatus = 2
) and then you can set the status line to include the buffer
url. For example: set statusline=%!sw#server#get_buffer_url(bufname('%'))
.
Following a foreign key
If you have activated the schema report (see the previous section), you can
(in a result set) follow a foreign key. In a result set, when you are on a
row, you can call SWSqlReferences
or SWSqlReferencedBy
commands.
These two commands take zero or one argument. If you call the commands without any argument, you will get a list of possible foreign keys, starting from the current result set and with the values from the current row. You need to select one, and then the corresponding query will be generated and run. Otherwise, via auto-completion, you can select which foreign key you want to follow.
The SWSqlReferences
command will tell you what rows the current row is
referencing in another tables, and the command SWSqlReferencedBy
will tell
you what other rows from other tables are referencing the current row.
Example
Let's say, that you have the following table structure:
+--------------+ +-------------+
| employees | | departments |
+--------------+ +-------------+
| id | | id |
| lastName | | name |
| departmentId | +-------------+
+--------------+
If you execute select * from employees
, you will get a list of all the
employees. If you go to the resultsets buffer and put the cursor on an
employee (let's say the one with departmentId = 10
and employee id = 1
),
you can do
SWSqlReferences departments(id)=employees(departmentId)
This will generate and automatically execute the query select * from departments where id = 10
Please note that you don't have to type in the argument, you can select it using the autocomplete of the command.
Same goes if you execute select * from departments where id = 10
and the you
select the deparment and you do
SWSqlReferencedBy employees(departmentId)=departments(id)
You will get a resultset with the employee with the id
1.
Including a file
If you want to create a stored procedure, you might want to execute the current
file. For this you have SWInclude
. The command will execute the entire file
using the WbInclude
command from SQL Workbench/J
. If you follow the command
by a !
, then the alternate delimiter is used. Otherwise the standard ;
delimiter is used. The command can also take one argument, which could be the
file to be included, if you don't want it to be the current file.
SQL commands
You can send a sql query to the DBMS from the vim command line using the
command SWSqlExecuteNow
. The parameters are the sql query. Please note that
by default no results will be shown. If you want to see all that happened on
the server side, use the SWSqlExecuteNowLastResult
command. This will show
you what happened with the last command sent from the vim command line.
This is useful if you want to put vim shortcuts for simple things. Like, for
example, you could have in your vimrc
:
nnoremap <leader>t :SWSqlExecuteNow wbdisplay tab;<cr>
Then pressing <leader>t
in normal mode, would set the display to tab for the
current buffer.
Note: This command will not be recorded in g:sw_last_sql_query
. The
delimiter is the ;
.
Searching
SQL Workbench/J
comes with two very handy and powerful commands:
WbGrepSource
and WbGrepData
. vim-sqlworkbench
takes advantage of both of
them and implements searching options. You can search in objects source code,
or you can search tables data.
Searching in objects source code
Of course, you can always execute WbGrepSource
in a sql buffer and send it to
the DBMS. For a full documentation of the command, please see
here.
Alternatively, you can call one of the three vim-sqlworkbench
search
commands available: SWSearchObject
, SWSearchObjectAdvanced
or
SWSearchObjectDefaults
.
The SWSearchObject
command will take one argument, which is the search
string. The command which will be sent to the DBMS is WbGrepSource <your_terms>
. This means that you execute a search with SQL Workbench/J
default values. For a list of these, see the above link.
Example: :SWSearchObject my_table<cr>
The SWSearchObjectAdvanced
command will open an interactive command prompt
asking for every parameter value, beginning with the search terms.
The SWSearchObjectDefaults
command takes one argument (the search terms) and
will perform a search using all the defaults defined in vim-sqlworkbench
plugin. These defaults can be changed in vimrc
.
Example: :SWSearchObjectDefaults my_table<cr>
Searching for data inside tables
You can execute WbGrepData
in a sql buffer and send it to the DBMS. For a
full documentation of the command, please see
here.
Alternatively, you can call one of the three vim-sqlworkbench
search
commands available: SWSearchData
, SWSearchDataAdvanced
or
SWSearchDataDefaults
.
All the three commands work as their counter parts for searching object.
If you are in an sql buffer, then the results are displayed in the result sets buffer. If you are in a database explorer, then the search results are displayed in the bottom left panel.
Exporting
vim-sqlworkbench
takes advantage of the very powerful SQL Workbench/J
command, WbExport
.
As usual, you can always execute the WbExport
command inside a sql buffer.
To see the full documentation of the WbExport
command, have a look
here.
Note: If you use the wbexport command, you need to send both of the queries
at once, by selecting both queries (first the WbExport
query and then the
exported query) and then running SWSqlExecuteSelected
. This happens because
the plugin will send after each statement a silent command to notice vim that
a new result is waiting. So, if you execute WbExport
, the exported statement
will be the silent one which is void and is not a select
statement.
Or you can execute the SWSqlExport
command. This will open an interactive
input dialog which will ask for the format and the destination file and will
export the last sql command. If you are in a database explorer, in the right
panel, you can click on "E". This shortcut is not modifiable. This will export
what ever is in the right panel, after asking for the format and the
destination file. Please note that because of extra dependencies required for
xls
export, vim-sqlworkbench
does not provide support for this format.
However, you can export as ods
, which is what you should use anyway. See
here or
here
Variables
SQL Workbench/j
supports user defined variables (you can have your queries
sent to the database parameterized). See
here.
By default, in SQL Workbench
, the variables are enclosed between $[
and
]
. These can be
changed.
You can use WbVarSet
and WbVarUnset
in a sql buffer. If you want the
system to ask for a value, then you can use the $[?
form of a parameter.
Please note that in VIM Sql Workbench
there is no difference between ?
and
&
, since there is no way to get a list of vars in vimscript
from SQL Workbench/J
Commands
SWDbExplorer
Parameters:
- profile name: the name of the profile for which to open the database explorer.
- port: the port on which the server listens
Opens a database explorer for the desired profile using the server from the specified port.
NOTE: If you set the
g:sw_config_dir
variable to point to the SQL Workbench/J
settings folder,
the command will autocomplete the profile names. See
here
SWDbExplorerClose
Parameters;
- profile name (optional): the name of the database explorer that should be closed.
Closes a database explorer. If no profile name is specified, if you are inside a database explorer, then that database explorer is closed. Otherwise, the system will generate an error.
If you specify a profile name, then the database explorer which is opened for the indicated profile is closed.
SWSqlExecuteCurrent
In an sql buffer executes the current statement. You can execute this command
in normal or insert mode. This is the statement between two consecutive
identifiers, or from the beginning of the file to the first identifier or from
the last identifier to the end of the file. You can change the delimiter using
the SWSqlDelimiter
command.
If you follow the command by a !
, then the alternate delimiter is used. You
can set the alternate delimiter in the connection properties.
NOTE: if the file that you are in is delimiter by a normal delimiter (;
) and
you want to execute the command with the alternate delimiter, you have to have
the alternate delimiter before and after the current query, otherwise, all the
other queries will be sent to the DBMS
. If you only want to execute one query
with the alternate delimiter and all the queries in your file are using the
standard semmicolumn delimiter, better select the query and execute
SWSqlExecuteSelected!
SWSqlExecuteSelected
In an sql buffer, executes the current selected statement. The command works in visual mode. Be careful to delete the range before typing the command.
If you follow the command by a !
, then the alternate delimiter is used. You
can set the alternate delimiter in the connection properties.
SWSqlExecuteAll
Send all sql statements from the buffer to the DBMS.
SWSqlToggleMessages
If you have a result set displayed in the result set buffer, you can toggle between the result displayed and the messages produced by the command with this command. The command works from the sql buffer and from the result set buffer.
SWSqlObjectInfo
In a sql buffer or in a result set buffer, you can position the cursor on top
of any word and call this command. The plugin will send to the DBMS DESC <word>
. If the word that you selected is a valid database object, you will
see its definition. Otherwise it will return an error.
SWSqlObjectSource
Like the previous command, if you are with your cursor on top of a word and call this command, the plugin will return it's source code, if the selected word is an object in the database. Otherwise, it will return an empty result set.
SWSqlExecuteNow
Parameters:
- port: the port on which to execute the command
- sql: The query to be sent to the DBMS
Executes a query against the DBMS on the indicated port.
SWSqlExecuteNowLastResult
Shows the communication with the server for the last SWSqlExecuteNow
command.
SWSqlExport
This command will export the last executed statement. Of course, if your last
statement did not produced any results, you will have an empty file. The
plugin will ask you about the format and about the output file. You can export
in one of the following formats: text
, sqlinsert
, sqlupdate
,
sqldeleteinsert
, xml
, ods
, html
, json
.
SWSearchObject
Parameters:
- search terms: the terms that you are searching.
This command performs a search in the source code of the database objects. It
uses the defaults of SQL Workbench/J
. The command which is used is
WbGrepSource
. You can see more details about the parameters and their
default values
here.
SWSearchObjectAdvanced
This command will perform an advanced search. It will ask for each possible parameter. You can cancel the search at any time by replying with an empty value. This, however, is not possible for the columns input, since the empty string in the columns means that you want all the columns but only the first row of each.
SWSearchObjectDefaults
Parameters:
- search terms: the terms that you are searching.
This command will perform a search using as default values for all the parameters the values defined through the vim variables:
g:sw_search_default_regex
g:sw_search_default_match_all
g:sw_search_default_ignore_case
g:sw_search_default_types
g:sw_search_default_compare_types
SWSearchData
Parameters:
- search terms: the terms that you are searching.
This command performs a search in the data in the tables. It uses the defaults
of SQL Workbench/J
. The command which is used is WbGrepData
. You can see
more details about the parameters and their default values
here.
SWSearchDataAdvanced
This command will perform an advanced search in the tables data. It will ask
for each possible parameter. You can cancel the search at any time by replying
with an empty value, with the exception of the excludeTables
parameter,
since an empty value here means that you want to search in all the tables and
is not an unusual request.
SWSearchDataDefaults
Parameters:
- search terms: the terms that you are searching.
This command will perform a search in tables data using as default values for all the parameters the values defined through the vim variables:
g:sw_search_default_ignore_case
g:sw_search_default_compare_types
g:sw_search_default_tables
g:sw_search_default_data_types
g:sw_search_default_exclude_tables
g:sw_search_default_exclude_lobs
SWDbExplorerToggleFormDisplay
If on a line in the results panel which contains a row in a resultset, then this row will be displayed as a form. If already displaying a form, then the resultset will be displayed.
SWSqlShowAllColumns
This will unhide all hidden columns from the current result set
SWSqlWipeoutResultsSets
This will wipeout the list of the resultsets. If you execute multiple sql statements, the results are stored in the resultsets buffer. When you close it, and then execute another sql statement, you will notice that the latest result sets are still there. If you don't want this, you can call this command. Next time you execute an sql statement, the resultsets will be empty.
If you want to wipeout all the resultsets for all buffers, you have to execute
the command followed by a !
(SWSqlWipeoutResultsSets!
).
SWSqlShowOnlyColumns
- column names: a list of white space separated list of columns to be shown
This will hide all the columns from the current resultset with the exception of the mentioned columns
Note: there is an autocomplete for the column names
SWSqlShowColumn
Parameters:
- column name: the name of the column to show
This will show the indicated column name (assuming that it is hidden)
Note: there is an autocomplete for the column name
SWSqlHideColumn
Parameters:
- column name: the name of the column to hide
This will hide the indeicated column.
Note: there is an autocomplete for the column name
SWSqlFilter
Parameters:
- where: The
where
condition for the current resultset.
This will construct a query from the given resultsets query with an added
where
to filter it.
Note: there is an autocomplete for the column name
SWSqlUnfilter
This will remove any filters applied on the specified resultset
#SWSqlBufferConnect
Parameters:
- buffer name: the name of the buffer to open and connect to an
SQL Workbench/J
instance (optional)
This command will open the selected buffer and connect it to an SQL Workbench/J
instance. If the parameter is missing, then the current buffer
will be connected to an SQL Workbench/J
instance.
Note: when you close the buffer, the SQL Workbench/J
instance process will
also be killed. If you want to close it gracefully, you can use
SWSqlBufferDisconnect
command, which will send an exit
to the SQL Workbench/J
.
SWSqlBufferDisconnect
This command will disconnect the current buffer from the SQL Workbench/J
and
close the sqlwbconsole
process.
SWSqlGetSqlCount
In a connected sql buffer, if you call this command, a query will be sent to
the DBMS fetching the number of rows of the current sql. For example, if your
cursor is on the select * from mu_table
; and you call this command, then
the query sent to the DBMS is select count(*) from (select * from my_table);
SWSqlGetObjRows
In a connected sql buffer, if you call this command, a query will be sent to
the DBMS to fetch the number of rows of the currently selected object. For
example, if your cursor is on top of the my_table
identifier and you call
this command, the query sent to the DBMS is select count(*) from my_table
.
SWSqlShowActiveConnections
This command will display a list of all the active connected buffers to a SQL Workbench/J
instance with their connection strings.
SWSqlShoLog
This command will open the log of the sql queries sent to the DBMS. If the
g:sw_log_to_file
is set to true, then the name of the file in which the log
is performed is returned. Otherwise you will see the log.
SWSqlShowLastResultset
This command will re-open the resultsets window without sending a new command to the DBMS.
SWSqlDeleteResultSet
This command will delete the currently selected resultset from the resultsets window.
SWSqlRefreshResultSet
This command will refresh the currently selected resultset from the resultsets window.
SWSqlBufferShareConnection
This command will share a connection between the current buffer and the one indicated in the command
SWSqlReferences
Parameters:
- reference: The column to follow.
Given a column name and a reference, this will fetch the rows from referenced from the current resultset in the destination table.
SWSqlReferencedBy
Paramaters:
- reference: The column to be followed in the current resultset
Given a column name and a reference, this will fetch the rows from the source table which are referencing the current row.
SWSqlGenerateInsert
Parameters:
- table: The first parameter is the table for which to generate the insert
- columns: The following parameters are the table columns (if missing, the insert will be generated for all table columns)
This will generate an insert for the given table and columns. The insert will
be copied to clipboard by default. If you want it to also be executed
immediatelly, you can expand it using the !
after the command (see :help bang
).
SWSqlGetMacroSql
If the cursor is on a macro, this command will return the current sql behind the macro see here. The sql is coppied to clipboard.
SWSqlInsertMatch
If you are with the cursor in the fields part of an sql, this will show you the corresponding value in a message. If your cursor is on the values part, then this will show you the corresponding column.
Note: This will not move the cursor by default. If you want you can add the
following shortcuts to your vimrc
:
nmap <Leader>* :SWSqlInsertMatch<cr>n
nmap <Leader># :SWSqlInsertMatch<cr>N
Then, in an insert columns part, you can click leader
and then #
and this
will also put the cursor on the value. However, if there is something else
between the cursor and the value with the same name, the cursor will stop
there (this is not 100% safe). Observe that the shortcut will execute
SWSqlInsertMatch
and then do a n
(next result).
CtrlPSW
If you activated the integration with CtrlP
, then this will open up directly
CtrlP
in the SQL Workbench/J profiles
tab
CtrlPClearSWCache
This will reset the profiles cache. Next time when you will access the CtrlP
workbench tab, the profiles will be read again.
SWInclude
Parameters:
- the file to include (optional, default the current file)
The command will include a given file or the current file. It will execute
wbinclude -file=<file or current file>;
. If you follow the command by a !
,
then the alternate delimiter is used.

+--------------------------------------+-----------------+-------------------+
Initially, I started this tool as a proof of concept for the console
capabilities of SQL Workbench/J
. It was just a toy. Without transactions, I
was basically using it just to do a few selects. Every time I would need
something more serious, I would open the GUI of SQL Workbench/J
and work
there.
In time though, this tool has become more powerfull with each version, and it
reached the phase where I don't need to open the GUI version for anything. The
last thing that I was using the GUI version for, was the dependencies tree.
Starting with version 7, once I succedeed in including this in the plugin
database explorer, I basically stopped using the GUI version and I work only
from within VIM
.
Another thing I noticed is that this plugin surpassed DbExt
in terms of
available features long time ago, so I thought to do a quick comparison.
From the beginning, I have to let the reader know that this comparison has
been done only based on the DbExt
documentation, since I was not able to
actually install DbExt
. Perl
dependency was a bump, and then trying to use
the mysql
client was a no go because I have mysql
installed in a non
standard path.
Another thing worth mentioning is that the comparison is with DbExt
perl
feature, since without Perl
and without transactions, DbExt
is just a
toy which cannot really be used profesionally. So the comparison is between
this plugin and the DbExt
ODBC features. Because of this, for example, when
it comes to cygwin
, there is no comparison to be made. I would go with this
plugin without thinking twice. This is why, for example I put a -
(missing
feature) to the asynchronous processing. DbExt
has asynchronous processing
only for the non ODBC
way of sending queries, which cannot even be
considered for professional usage. The ODBC does not have asynchronous
processing. So, let's begin.
Installation
When it comes to installing the two plugins, for DbExt
, you need root
permissions (if you don't have perl) installed on the computer, you need a vim
compiled with perl
and you need to install perl
modules. In comparison, for
vim-sql-workbench
, you only need to install the SQL Workbench/J
application,
which is a java app (so no root needed) and to download the required jdbc
driver. That's it. So, a big plus for this plugin.
GUI
In terms of GUI, DbExt has menus integration, which this plugin lacks. This is a plus for DbExt.
Profiles
DbExt has an option to ask for a connection parameters, which this plugin does
not have at the moment (will be implemented in a future version). Other than
that, the profiles for this plugin can be managed using the GUI of SQL Workbench/J
, which is a very convenient way of doing this, so in terms of
profile management, a plus again for vim-sql-workbench
. Also, another plus it
is represented by the possibility of SQL Workbench/J
to have readonly
profiles.
SQL windows and resultsets
When it comes to the basics that anyone could expect from a plugin made to execute SQL queries agains a database, both softwares have everything (refresh a resultset, parameters substitution, history, transactions etc.).
But when it comes to advanced features, there cannot be any comparison.
vim-sql-workbench
has asynchronious execution, very powerfull trully
intellisense autocompletion, export of results, import from various formats,
confirmation of commands execution, following of foreign keys (what other tables
are referencing the current row, or what other tables is the current row
referencing). DbExt
lacks all of these (the autocomplete of DbExt
is again,
a toy compared with the intellisense offered by this plugin), so again, a very
big plus for vim-sql-workbench
.
Also, this plugin has a database explorer, which includes a database references tree.
Tools
One thing that DbExt
is doing and this plugin is not is parsing non-sql files,
extracting a query and running it against a database. This is a plus for
DbExt
.
But in terms of tools, this plugin has macros (basically sql queries shortcuts),
can search for terms in table definitions or can search for data in tables, can
compare two databases, can copy data across databases or can use special
comments in queries which will be interpreted by the SQL Workbench/J
engine
(like annotations). Altough all these tools are comming as a part of SQL Workbench/J
, they can be used directly in vim with the help of this plugin. As
I was saying in the beginning of this chapter, no need to open the GUI SQL Workbench/J
. So, again, in terms of tools, a big plus for vim-sql-workbench
.
Conclusion
As seen, this plugin has surpassed DbExt
in terms of features long time ago.
However, if anyone considers that I've missed something, please open an issue
and let me know.
