Features

  • Auto-completion as you type for SQL keywords as well as tables, views and columns in the database.
  • Syntax highlighting using Pygments.
  • Smart-completion (enabled by default) will suggest context-sensitive completion.
    • SELECT * FROM <tab> will only show table names.
    • SELECT * FROM users WHERE <tab> will only show column names.
  • Support for multiline queries.
  • Favorite queries with optional positional parameters. Save a query using \fs alias query and execute it with \f alias whenever you need.
  • Timing of sql statements and table rendering.
  • Config file is automatically created at ~/.myclirc at first launch.
  • Log every query and its results to a file (disabled by default).
  • Pretty prints tabular data (with colors!)
  • Support for SSL connections

Some features are only exposed as Key Bindings:

The following key bindings are special to mycli:

F2

Enable/Disable SmartCompletion Mode.

F3

Enable/Disable Multiline Mode.

F4

Toggle between Vi and Emacs mode.

Tab

Force autocompletion at cursor.

C-space

Initialize autocompletion at cursor.

If the autocompletion menu is not showing, display it with the appropriate completions for the context.

If the menu is showing, select the next completion.

ESC Enter

Introduce a line break in multi-line mode, or dispatch the command in single-line mode.

The sequence ESC-Enter is often sent by Alt-Enter.

C-x p (Emacs-mode) or > (Vi-mode)

Prettify and indent current statement, usually into multiple lines.

Only accepts buffers containing single SQL statements.

C-x u (Emacs-mode) or < (Vi-mode)

Unprettify and dedent current statement, usually into one line.

Only accepts buffers containing single SQL statements.
