Situation: You want to connect to SQL Server through Perl. How would you do that?

Perl supports access to all of the major database systems through a number of extensions
provided through the DBI toolkit, a third-party module available from CPAN. Under Windows you can use either the DBI interfaces or the Win32::ODBC toolkit, which provides direct access to any ODBC-compliant database including SQL Server database products.
Using DBI:
use DBI;
my $dbh = DBI->connect(DSN);
Using ODBC:
Use Win32::ODBC;
$database = new Win32::ODBC("DSN" [, CONNECT_OPTION, ...]);
