Oh heck, I hadn't even noticed he was asking about escaping things. I guess it really matters what he means by escaping them. If he's talking url encoding decoding, that's something you could do safely in the db (again, with something like pl/PHP or pl/perl) but SQL escaping should be done before the db ever sees the data. ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
