Here is my contribution:
1. Custom SQL lexer registered and implemented directly in ctlSQLBox
class.
I've done this to detect AS '....' construction.
Everything inside quotes after AS will be highlighted as in regular SQL
code. Escaped quotes (\') are also detected correctly.
Now, the more preferable way to edit/update stored procedures will be
using Query window (instead of Properties dialog). So, just select a
function, click SQL on toolbar and edit the code. Once your change is
ready just click "Play" and the procedure will updated in the DB. Way
more convenient, isn't it?
2. More keywords added such as UNIUON, INNER, OUTER, etc.
3. Find Dialog. Press Ctrl-F in any SQL box to activate Find dialog.
No regular expressions though, since wx UI does not support that in its
Find dialog. Custom Find dialog needs to be implemented for that.
4. Edit Menu in Query window. I also added Edit menu to the Query
window.

Yurgis,
please send the output of "cvs diff" to Dave, and he will merge your
