It should show up with that technique; if you just want to see whether that particular module's installed (i.e. you're not trying to get a full list of what drivers you have installed), try

perl -MDBD::Mysql -e '1'
[download]

in a DOS window, and see if you get an error (you might want to check my captialization on the module name, just to be sure.)

If that doesn't work, try it by hand: execute perl -V in a DOS window and look at the @INC directories; poke through them for a file in a directory that looks like DBD\Mysql.pm.

Hi i tried typing

perl -MDBD::Mysql -e '1'

and i did not get an error, i got no feedback at all.

I also checked in c:\perl\site\dbd\ and mysql.pm exists.

my @datasources = DBI->data_sources($driver);

If I remove the statements that deal with the data_sources, it works fine:

#!/usr/bin/perl

use strict;
use DBI;

my @drivers = DBI->available_drivers();

die "No drivers found!\n" unless @drivers;

foreach my $driver ( @drivers ) {
  print "Driver: $driver\n";
}

Which returns:

Driver: ADO
Driver: ExampleP
Driver: Oracle
Driver: Pg
Driver: Proxy
Driver: mysql
[download]

Maybe DBD::Proxy has a problem with data_sources?

Sutch, this works exactly the same for me.

Once I removed that line I get



Driver: ExampleP

Driver: Multiplex

Driver: Proxy

Driver: mysql
[download]


Does this glitch have any affect on any of the drivers (in particular mysql). Are these driver working functionaly, as normal, in other words will i have any problems using these drivers later on?

Without reading up too much about why DBD::Proxy may be choking on the data_sources call, I did find that DBD::Proxy should not have any effect on Mysql. From the DBD::Proxy documentation:

DBD::Proxy is a Perl module for connecting to a database via a remote DBI driver.

This is of course not needed for DBI drivers which already support connecting to a remote database, but there are engines which don't offer network connectivity.

I would suggest limiting your data_sources method calls to only driver(s) that your are going to use. For example, use a conditional such as if ($driver eq 'mysql') so that only the mysql driver is queried for data_sources.
