Better indentation for sql-mode in Emacs
sql-smie-mode is an Emacs minor mode for indenting SQL. It depends
on the SMIE library introduced in Emacs 23.3.
The mode is currently incomplete, but I think it works better than
sql-indent.el in many cases already.
Place sql-smie-mode.el in a directory on your load path and add the
following to your emacs init file:
(require 'sql-smie-mode) (add-hook 'sql-mode-hook 'sql-smie-mode)
