I installed the latest version of mod_perl (1.24), linked it statically to
apache 1.3.12. (use perl 5.6). I simply want to access a MySQL database
via the DBI package (v 1.14). I installed ApacheDBI 0.87
I wrote a simple script to access a mysql database. This script works fine,
both from the command line and as a CGI script. The script stops however
at the connect call when I run it as a mod_perl module. I disabled
PerlFreshRestart, because it produced segmentation faults. I found
some similar bug reports in the mailing list archive, but found no postings
about a solution to the problem.
Below I include the script text, and a DBI trace. Who could help? I can
supply more debug information upon request.
The script without a query string provides a popup menu. Hitting the submit
button will actually access the database.
#!/usr/local/bin/perl
use CGI qw/:standard/;
print header,
start_html('Database browser'),
h1('Database browser'),
start_form, "Which video",
p,popup_menu(-name=>'assetid',-values=>['16777267','16777269','16777260']),
submit,
end_form,
hr;
if (param() ) {
print em(join (", " , param('assetid'))), hr;
$assetid = param('assetid');
use DBI;
$Apache::DBI::DEBUG = 1;
#use strict;
DBI->trace(6,"/tmp/dbi.log");
#removed uid / pwd parameters....
$dbh = DBI->connect('dbi:mysql:vip;host=####', '###', '###');
$sql = "SELECT * FROM spoken_text WHERE asset_id = $assetid";
$sth = $dbh->prepare($sql);
$sth->execute || die "Could not execute SQL statement: $!\n";
while (@rows=$sth->fetchrow_array) {
print "@rows\n\n";
}
}
Here's the trace log from DBI:
DBI 1.14-nothread dispatch trace level set to 6
