I'm running a security audit on my server. When UBB displays a MySQL Error, the security firm considers it a vulnerability because path and table information are displayed. How can I turn off the MySQL errors like the one below?

Code
Script: /Library/Tenon/WebServer/WebSites/www.realtree.com/forums/showmembers.php
Line#: 200
SQL Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-25, 25' at line 9
