vim-dadbod-ui

Simple UI for vim-dadbod. It allows simple navigation through databases and allows saving queries for later use.

With nerd fonts:

Video presentation by TJ:

Tested on Linux, Mac and Windows, Vim 8.1+ and Neovim.

Features:

• Navigate through multiple databases and it's tables and schemas
• Several ways to define your connections
• Save queries on single location for later use
• Define custom table helpers
• Bind parameters (see :help vim-dadbod-ui-bind-parameters)
• Autocompletion with vim-dadbod-completion
• Jump to foreign keys from the dadbod output (see :help <Plug>(DBUI_JumpToForeignKey))
• Support for nerd fonts (see :help g:db_ui_use_nerd_fonts)
• Async query execution

Installation

Use your favorite package manager. If you don't have one, I suggest vim-packager

function! PackagerInit() abort
  packadd vim-packager
  call packager#init()
  call packager#add('kristijanhusak/vim-packager', { 'type': 'opt' })
  call packager#add('tpope/vim-dadbod')
  call packager#add('kristijanhusak/vim-dadbod-ui')
endfunction

" This is just an example. Keep this out of version control. Check for more examples below.
let g:dbs = {
\  'dev': 'postgres://postgres:mypassword@localhost:5432/my-dev-db'
\ }

Configuration with lazy.nvim

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,
}

After installation, run :DBUI, which should open up a drawer with all databases provided. When you finish writing your query, just write the file (:w) and it will automatically execute the query for that database and it will automatically execute the query for selected database.

Databases

There are 3 ways to provide database connections to UI:

1. Through environment variables
2. Via g:dbs global variable
3. Via :DBUIAddConnection command

Through environment variables

If $DBUI_URL env variable exists, it will be added as a connection. Name for the connection will be parsed from the url. If you want to use a custom name, pass $DBUI_NAME alongside the url. Env variables that will be read can be customized like this:

let g:db_ui_env_variable_url = 'DATABASE_URL'
let g:db_ui_env_variable_name = 'DATABASE_NAME'

Optionally you can leverage dotenv.vim to specific any number of connections in an .env file by using a specific prefix (defaults to DB_UI_). The latter part of the env variable becomes the name of the connection (lowercased)

# .env
DB_UI_DEV=...          # becomes the `dev` connection
DB_UI_PRODUCTION=...   # becomes the `production` connection

The prefix can be customized like this:

let g:db_ui_dotenv_variable_prefix = 'MYPREFIX_'

Via g:dbs global variable

Provide list with all databases that you want to use through g:dbs variable as an array of objects or an object:

let g:dbs = {
\ 'dev': 'postgres://postgres:mypassword@localhost:5432/my-dev-db',
\ 'staging': 'postgres://postgres:mypassword@localhost:5432/my-staging-db',
\ 'wp': 'mysql://root@localhost/wp_awesome',
\ }

Or if you want them to be sorted in the order you define them, this way is also available:

let g:dbs = [
\ { 'name': 'dev', 'url': 'postgres://postgres:mypassword@localhost:5432/my-dev-db' }
\ { 'name': 'staging', 'url': 'postgres://postgres:mypassword@localhost:5432/my-staging-db' },
\ { 'name': 'wp', 'url': 'mysql://root@localhost/wp_awesome' },
\ ]

Just make sure to NOT COMMIT these. I suggest using project local vim config (:help exrc)

Via :DBUIAddConnection command

Using :DBUIAddConnection command or pressing A in dbui drawer opens up a prompt to enter database url and name, that will be saved in g:db_ui_save_location connections file. These connections are available from everywhere.

Connection related notes

It is possible to have two connections with same name, but from different source. for example, you can have my-db in env variable, in g:dbs and in saved connections. To view from which source the database is, press H in drawer. If there are duplicate connection names from same source, warning will be shown and first one added will be preserved.

Settings

Table helpers

Table helper is a predefined query that is available for each table in the list. Currently, default helper that each scheme has for it's tables is List, which for most schemes defaults to g:db_ui_default_query. Postgres, Mysql and Sqlite has some additional helpers defined, like "Indexes", "Foreign Keys", "Primary Keys".

Predefined query can inject current db name and table name via {table} and {dbname}.

To add your own for a specific scheme, provide it through .g:db_ui_table_helpers.

For example, to add a "count rows" helper for postgres, you would add this as a config:

let g:db_ui_table_helpers = {
\   'postgresql': {
\     'Count': 'select count(*) from "{table}"'
\   }
\ }

Or if you want to override any of the defaults, provide the same name as part of config:

let g:db_ui_table_helpers = {
\   'postgresql': {
\     'List': 'select * from "{table}" order by id asc'
\   }
\ }

Auto execute query

If this is set to 1, opening any of the table helpers will also automatically execute the query.

Default value is: 0

To enable it, add this to vimrc:

let g:db_ui_auto_execute_table_helpers = 1

Icons

These are the default icons used:

let g:db_ui_icons = {
    \ 'expanded': '▾',
    \ 'collapsed': '▸',
    \ 'saved_query': '*',
    \ 'new_query': '+',
    \ 'tables': '~',
    \ 'buffers': '»',
    \ 'connection_ok': '✓',
    \ 'connection_error': '✕',
    \ }

You can override any of these:

let g:db_ui_icons = {
    \ 'expanded': '+',
    \ 'collapsed': '-',
    \ }

Help text

To hide Press ? for help add this to vimrc:

let g:db_ui_show_help = 0

Pressing ? will show/hide help no matter if this option is set or not.

Drawer width

What should be the drawer width when opened. Default is 40.

let g:db_ui_winwidth = 30

Default query

DEPRECATED: Use Table helpers instead.

When opening up a table, buffer will be prepopulated with some basic select, which defaults to:

select * from table LIMIT 200;

To change the default value, use g:db_ui_default_query, where {table} is placeholder for table name.

let g:db_ui_default_query = 'select * from "{table}" limit 10'

Save location

All queries are by default written to tmp folder. There's a mapping to save them permanently for later to the specific location.

That location is by default ~/.local/share/db_ui. To change it, addd g:db_ui_save_location to your vimrc.

let g:db_ui_save_location = '~/Dropbox/db_ui_queries'

Mappings

These are the default mappings for dbui drawer:

• o / <CR> - Open/Toggle Drawer options (<Plug>(DBUI_SelectLine))
• S - Open in vertical split (<Plug>(DBUI_SelectLineVsplit))
• d - Delete buffer or saved sql (<Plug>(DBUI_DeleteLine))
• R - Redraw (<Plug>(DBUI_Redraw))
• A - Add connection (<Plug>(DBUI_AddConnection))
• H - Toggle database details (<Plug>(DBUI_ToggleDetails))

For queries, filetype is automatically set to sql. Also, two mappings is added for the sql filetype:

• <Leader>W - Permanently save query for later use (<Plug>(DBUI_SaveQuery))
• <Leader>E - Edit bind parameters (<Plug>(DBUI_EditBindParameters))

Any of these mappings can be overridden:

autocmd FileType dbui nmap <buffer> v <Plug>(DBUI_SelectLineVsplit)

If you don't want any mappings to be added, add this to vimrc:

let g:db_ui_disable_mappings = 1

TODO

• Test with more db types
