Why don't you use SQL to do it for you? Here are two methods that will give random results:
select top 5000 * from [tablename] where ... order by newid()select * from [tablename] tablesample(5000 rows) where ...The second one is faster if you are on SQL Sever 2005 and up. You can also use %'s as in tablesample(5 percent) or top 5 percent. You can find this on StackOverflow.com
