SQL-Bless

<English> / <Japanese>

The SQL-Bless is a command-line database client like SQL*Plus or psql.

• Emacs-like keybindings for inline editing of multiple lines of SQL.
  • The action of Enter key will only insert a line feed code.
  • Press Ctrl-J or Ctrl-Enter to execute the input.
• Save the result of SELECT in CSV format
• Supported RDBMS
  • SQLite3
  • Oracle
  • PostgreSQL
  • Microsoft SQL Server
  • MySQL
• Allows editing database records directly, similar to a spreadsheet (with the EDIT command)
• Auto commit is disabled.

Key	Binding
Enter, Ctrl-M	Insert a linefeed
Ctrl-Enter/J	Execute text as SQL
Ctrl-F/B	Move Cursor forward or backward
Ctrl-N/P	Move Cursor or refer history
Ctrl-C	Exit with rollback
Ctrl-D	Delete character or submit EOF (exit with rollback)
ALT-P, Ctrl-Up, PageUp	Insert the previous SQL (history)
ALT-N, Ctrl-Down, PageDown	Insert the next SQL (history)

Supported commands

• SELECT / INSERT / UPDATE / DELETE

  • INSERT, UPDATE and DELETE begin the transaction automatically.

• COMMIT / ROLLBACK

• SPOOL

  • spool FILENAME .. open FILENAME and write log and output.
  • spool off .. stop spooling and close.

• EXIT / QUIT

  • Rollback a transaction and exit SQL-Bless.

• START filename

  • Start the SQL script given with filename

• REM comments

• DESC [tablename] / \D [tablename]

  • When the tablename is given, show the specification of the the table
  • Without the tablename, show the list of tables.

• HISTORY

  • Show the history of input SQLs

• EDIT tablename [WHERE conditions...]

  • Start an editor to modify the selected records of the table.
  • In the editor, these keys are bound.
    • x or d: set NULL to the current cell
    • c: apply changes
    • q or ESC: quit without applying changes
  • Because the EDIT statement automatically generates SQL from data changed in the editor, it may not be able to properly represent SQL data for special types specific to individual databases. If you find it, we would appreciate it if you could contact us.

• Semicolon ; is a statement seperator when script is executed.

• When sql is input interactively, Semicolon ; is ignored.
