DBD::MySQL

I have installed DBD:MySQL 4.0.18 on Perl 5.10, Mac OS X 10.6.

Any ideas about what I might have done wrong? About what I need to do to
fix it?
The following test script produces the errors shown below:
#!/usr/bin/perl -w
use strict;
use warnings;

use DBI;
use DBD::MySQL;

my $GCdbSchemaName = "gfrm";
my $GCdbUn = "gfrm";
my $GCdbPw = "gfrm";

my $dbHandle = DBI->connect("DBI:mysql:database=$GCdbSchemaName", $GCdbUn,
$GCdbPw);
exit;

Errors:

Well on my machine that code says "Can't locate DBD/MySQL.pm". It says
that because the module is actually called DBD::mysql.

So I doubt you have shown us the actual code you ran. Or do you have
some other module?

And you don't need to use DBD::mysql because DBI will do that.

Cheers, Dave

PS You don't need -w on the shebang line and on the command line and use
warnings as well! perl will get the hint with just one of them :)

..unless he's using it on a case-insensitive filesystem.

G'luck,

This sentence every third, but it still comprehensible.

Okay, that was a bit poorly-phrased :) Even if the original poster is
using the module on a case-insensitive filesystem, it would still be
called "DBD::mysql" and you'd still be right that it's actually called
"DBD::mysql" :) But this would not be a problem.

G'luck,
Peter

If you think this sentence is confusing, then change one pig.
