Say my database name is Jessica_DB, my user name is jessica, and my password jessica_pwd.

Perl

To connect to Microsoft SQL Server using Perl with Win32::ODBC module

use Win32::ODBC;
my $dsn = "DSN=Jessica_DB;UID=jessica;PWD=jessica_pwd;";
my $DB  = Win32::ODBC->new($dsn);
$DB->Sql("SELECT f1, f2, f3 FROM MyTable");
$DB->FetchRow();
($f1, $f2) = $DB->Data("f1", "f2");
print "f1 = ". $f1;
$DB->Close();

VBScript

To connect to MS SQL Server using VBScript

Const adOpenStatic = 3
Const adLockOptimistic = 3
Set objConnection = CreateObject("ADODB.Connection")
Set objRecordSet = CreateObject("ADODB.Recordset")
objConnection.Open _
        "Provider=MSDASQL.1;Data Source=Jessica_DB;" & _
              "Trusted_Connection=Yes;" & _
                     "User ID=jessica;Password=jessica_pwd;"
objRecordSet.Open "SELECT * FROM MyTable", _
          objConnection, adOpenStatic, adLockOptimistic

objRecordSet.MoveFirst
Wscript.Echo objRecordSet.RecordCount

Python

Ever wonder how to create those cool images with reflection, such as the image below? You can create them using Inkscape and GIMP, two free Open Source tools, and of course, with Photoshop. When I need to add reflection to an image quickly, I usually use Inkscape. Check it out! It’s great for making simple site logo as well.
