DB Configuration

The connection to the RDBMS is essential to take advantage of the functionality provided by sqls. You need to set the connection to the RDBMS.

Configuration Methods

There are the following methods for RDBMS connection settings, and they are prioritized in order from the top. Whichever method you choose, the settings you make will remain the same.

  1. Configuration file specified by the -config flag
  2. workspace/configuration set to LSP client
  3. Configuration file located in the following location
    • $XDG_CONFIG_HOME/sqls/config.yml ("$HOME/.config" is used instead of $XDG_CONFIG_HOME if it's not set)

Configuration file sample

# Set to true to use lowercase keywords instead of uppercase.
lowercaseKeywords: false
connections:
  - alias: dsn_mysql
    driver: mysql
    dataSourceName: root:root@tcp(127.0.0.1:13306)/world
  - alias: individual_mysql
    driver: mysql
    proto: tcp
    user: root
    passwd: root
    host: 127.0.0.1
    port: 13306
    dbName: world
    params:
      autocommit: "true"
      tls: skip-verify
  - alias: mysql_via_ssh
    driver: mysql
    proto: tcp
    user: admin
    passwd: Q+ACgv12ABx/
    host: 192.168.121.163
    port: 3306
    dbName: world
    sshConfig:
      host: 192.168.121.168
      port: 22
      user: sshuser
      passPhrase: ssspass
      privateKey: /home/lighttiger2505/.ssh/id_rsa

Workspace configuration Sample

  • setting example with vim-lsp.
if executable('sqls')
    augroup LspSqls
        autocmd!
        autocmd User lsp_setup call lsp#register_server({
        \   'name': 'sqls',
        \   'cmd': {server_info->['sqls']},
        \   'whitelist': ['sql'],
        \   'workspace_config': {
        \     'sqls': {
        \       'connections': [
        \         {
        \           'driver': 'mysql',
        \           'dataSourceName': 'root:root@tcp(127.0.0.1:13306)/world',
        \         },
        \         {
        \           'driver': 'postgresql',
        \           'dataSourceName': 'host=127.0.0.1 port=15432 user=postgres password=mysecretpassword1234 dbname=dvdrental sslmode=disable',
        \         },
        \       ],
        \     },
        \   },
        \ })
    augroup END
endif
  • setting example with coc.nvim.

In coc-settings.json opened by :CocConfig

{
    "languageserver": {
        "sql": {
            "command": "sqls",
            "args": ["-config", "$HOME/.config/sqls/config.yml"],
            "filetypes": ["sql"],
            "shell": true
        }
    }
}
require'lspconfig'.sqls.setup{
  settings = {
    sqls = {
      connections = {
        {
          driver = 'mysql',
          dataSourceName = 'root:root@tcp(127.0.0.1:13306)/world',
        },
        {
          driver = 'postgresql',
          dataSourceName = 'host=127.0.0.1 port=15432 user=postgres password=mysecretpassword1234 dbname=dvdrental sslmode=disable',
        },
      },
    },
  },
}
  • Setting example for Sublime Text 4

    Install the LSP Client by Opening the command palette and run Package Control: Install Package, then select LSP.

    Open Preferences > Package Settings > LSP > Settings and add the "sqls" client configuration to the "clients":

{
    "show_diagnostics_count_in_view_status": true,
    "clients": {
        "sqls": {
            "enabled": true,
            "command": ["/path/to/sqls binary"],
            "selector": "source.sql"
        }
    }
}

I'm sorry. Please wait a little longer for other editor settings.
