Hi all,
I thought I can hit a nice milestone today, but it seems that I have hit
a strange obstacle instead.
In my tests, the following code will run, but when it terminates an
error message will be shown.
use strict;
use warnings;
use DBI;
use threads;
doIt();
doIt();
sub doIt
{
my $dbh = DBI->connect('dbi:mysql:database','username','password');
my $stmt = $dbh->prepare ('select id from tablename');
$stmt->execute();
while (my $record=$stmt->fetchrow_hashref('NAME_lc')) {}
}
Change the database connection parameters (eg. username, password, table
name) to your database.
My analysis of the problem is as follows:
1. Using the ODBC driver is ok. I've tested with MSSQL connection and
it's fine.
2. The problem lies with using threads alongside DBI. If I take out 'use
threads' all is well.
3. There are 2x doIt() calls because it only fails on the second
database connection.
4. It seems to be related to fetchrow_hashref(), because if I take that
out, all is fine.
Can someone confirm this? Is there anybody who can suggest a workaround?
Thanks.
