I just came across this: http://dev.mysql.com/doc/refman/5.0/en/faqs-sql-modes.html http://dev.mysql.com/doc/refman/5.0/en/server-sql-mode.html setting mode to ANSI should help to debug the code and improve portability to other DB even if I've heard that the ANSI mode is not as strict as you'd expect. I remember a similar proposal for increasing the "strictness" of PHP setting and verbose error reporting before committing to core. -- Ivan Sergio Borgonovo http://www.webthatworks.it
