Configuration using lazy.nvim with vim-dadbod-ui

return {
  {
    'kristijanhusak/vim-dadbod-ui',
    dependencies = {
      { 'tpope/vim-dadbod', lazy = true },
      { 'kristijanhusak/vim-dadbod-completion', ft = { 'sql', 'mysql', 'plsql' }, lazy = true },
    },
    cmd = {
      'DBUI',
      'DBUIToggle',
      'DBUIAddConnection',
      'DBUIFindBuffer',
    },
    init = function()
      -- Your DBUI configuration
      vim.g.db_ui_use_nerd_fonts = 1
    end,
  },
  { -- optional saghen/blink.cmp completion source
    'saghen/blink.cmp',
    opts = {
      sources = {
        -- add vim-dadbod-completion to your completion providers
        completion = {
          enabled_providers = { "lsp", "path", "snippets", "buffer", "dadbod" },
        },
        providers = {

        },
      },
    },
  }
}

Features

• Autocomplete table names, with automatic quoting where needed. Works for all schemes that vim-dadbod supports.
• Autocomplete table columns, context aware. Also knows to read aliases (select * from mytable tbl where tbl.id = 1). Currently works for PostgreSQL, MySQL, Oracle, SQLite (requires version 3.37.0 (2021-11-27)) and SQLserver/MSSQL.
• Out of the box integration with vim-dadbod-ui

How it works

• If an sql buffer is created by vim-dadbod-ui, it reads all the configuration from there. It should work out of the box.
• If vim-dadbod-ui is not used, vim-dadbod g:db or b:db is used. If you want, you can also add b:db_table to limit autocompletions to that table only.

Settings

Default mark for completion items is [DB]. To change it, add this to vimrc:

let g:vim_dadbod_completion_mark = 'MYMARK'

Commands

This plugin caches the database tables and columns to leverage maximum performance. If you want to clear the cache at any point just run:

:DBCompletionClearCache

Todo

• [ ] Integration for column autocompletion with more database types
