# A.4. DBD::Sponge::db prepare failed

The following error message may appear due to a bug in DBD::mysql (over which the Bugzilla team have no control):

     DBD::Sponge::db prepare failed: Cannot determine NUM_OF_FIELDS at D:/Perl/site/lib/DBD/mysql.pm line 248.
      SV = NULL(0x0) at 0x20fc444
      REFCNT = 1
      FLAGS = (PADBUSY,PADMY)

To fix this, go to `<path-to-perl>/lib/DBD/sponge.pm` in your Perl installation and replace

     my $numFields;
     if ($attribs->{'NUM_OF_FIELDS'}) {
         $numFields = $attribs->{'NUM_OF_FIELDS'};
     } elsif ($attribs->{'NAME'}) {
         $numFields = @{$attribs->{NAME}};

with

     my $numFields;
     if ($attribs->{'NUM_OF_FIELDS'}) {
         $numFields = $attribs->{'NUM_OF_FIELDS'};
     } elsif ($attribs->{'NAMES'}) {
         $numFields = @{$attribs->{NAMES}};

(note the S added to NAME.)
