Regarding SQL Injection: Sorry to get into this, but I use ColdFusion and cfc's to query the database. Then I wrap my passed values in Val() so that no SQL injection can be performed. I've been told that this works well, and have had my code checked by others far better than I. They have confirmed. Do you agree? Thanks.
