Hey All-
I am trying to improve the speed of a website and was wondering if
anyone had any ways I can rewrite these queries so that they actually
run with some descent speed.
Its a really nasty query and I'm not sure where to start, I'd like to
now have to redo the tables and I already put some indexes on it which
improved speed a lot but these queries are still very slow. You can most
certainly laugh to yourselves on this one... jsut trying to get some
opinions on what I should do with this.
Thanks-
Matt
