Emacs sql-modes with intelligent indentation and hiliting?

I am looking for sql-modes for editing oracle sql-code in emacs. These are what I have found so far:

sql-mode.el by Rob Riepel, Revision 2.5 (version 2.0) from 12-feb-94. This seems to be particularly good, but I haven't had the chance to try it out properly.

sql-mode.el by Jim Lange, Revision 1.2 from 27-mar-90. I couldn't get the interactive mode to work with sqlplus. Doesn't seem to be very oriented towoards oracle.

sql.el by Lynn Slater from 3-nov-89. I haven't really used this at all, it's very badly documented. I don't quite understand how to use it.

  In all of the above modes abbreviations seems to be the major feature. What I would be more interested in is intelligent indentation and text hiliting. Are there any other sql-modes than the ones I have found? Since none of the above ones do any indentation I usually use indented-text-mode instead. I am also thinking about writing some hiliting code myself, but it would naturally be easier if someone else had done it before me.

Thanks in advance for any help.
