Hi List I am trying to make a Database Abstraction Layer so I can which the DB of my application between MySQL and Postgresql. I have been looking at the way phpBB does it, and it seems that it is only then php-functions which are different. The SQL seems to be the same. Is it save to assume that I can use the same SQL, or should i make some exceptions?

Simple SQL is almost identical. But there are many of the more advanced functions that have major differences. Check out ADOdb for an existing abstraction layer that handles a lot of them. http://adodb.sourceforge.net/ -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk// Firebird - http://www.firebirdsql.org/index.php
