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,
}

• 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

• 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.

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

let g:vim_dadbod_completion_mark = 'MYMARK'

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

• Integration for column autocompletion with more database types
