MySQL ODBC hangs

Stephen Toney has asked for the wisdom of the Perl Monks concerning the following question:

Hi everyone,

Using MyODBC with MySQL 5.0 hangs after delivering the data from the database. Here's a tiny program the shows the problem.

#! /usr/local/bin/perl -w 
use strict; 
use CGI qw(:standard escapeHTML); 
$::DSN = "MWEBMYSQL"; 
use DBI; $::dbh = DBI->connect ("dbi:ODBC:$::DSN", "ODBC") || die ("Ca
+nnot connect to Data Source '$::DSN'"); 
my ($count) = $::dbh->selectrow_array ("select count(*) from logon"); 
print header ('text/html', '200 OK'); 
print "<html><body>Found $count records in LOGON</body></html>";

This works with SQL Server and Foxpro db's using ODBC, but with MySQL there is no response until the server times out. When I run it from the command line the correct results are shown, but the cursor stays right after </html> and there is no command prompt until the server times out. Since the correct results are shown, I know it's not a connection problem. So what could it be?

MySQL works correctly from mysql.exe and also when I issue ODBC queries from another language. Just not with Perl.

"marto" suggested (thanks!) that I should use DBD::MySQL. However, the latest on the ActiveState website is version 2.1004, November 16, 2001. Has anyone tried this with MySQL 5.0 yet?

Thanks a million for any ideas!

Stephen

Hi Stephen Toney, On Cpan the DBD::mysql module version is 3.0002. You may want to read A guide to installing modules for Win32 by holli from the Tutorials section of this site. Hope this helps.	[reply]

Thanks, I just grabbed it from theoryx5. Somehow I thought ActiveState would always be the most up-to-date. Silly me!	[reply]
