You may wish to turn off RaiseErrors...you can still get the dbi
errors by doing: $dbi = $DBI::errstr; Embed this in your query -
if (!defined $rv) ... $dbi = $DBI::errstr; and so on.
The reason to do this is that you can then write your own stderr and
include the dbi errstr...this is very handy if you want to beef up the
debugging output that gets dumped to the apache error_log (I use DBI
alongside CGI in perl scripts).
The problem with RaiseErrors is that it overwrites any stderr the
script is looking to dump to the error_log...just an FYI.

The author of DBI (Tim Bunce) has an excellent book published by Tim
O'Reilly called Programming The Perl DBI Interface.
