mysql log of failed inserts?

Using debian stable...

Is there a log somewhere of failed mysql commands? These would have been generated by some bad php scripting... looking to find failed inserts.

Thanks

 

Maybe this helps you a bit: http://dev.mysql.com/doc/refman/5.1/en/server-system-variables.html#sysvar_log_warnings

But afaik you can not log mysql-errors caused by any script or whatsoever. So it's part of the script itself to do the errorhandling and logging.
