I need to select random 5% rows from 100 records. The Select Top (5) percent gives me the first 5 rows. I want a random 5% but not in order. Any suggestions ?

Just select your top 5 percent rows and order by NEWID()

Even easier use the TABLESAMPLE funciton in sql 2005


select * from MyTable tablesample(5 percent)



there are some limitations on this though check BOL, the smaller the number of rows in your table the less accurate the % sample will be.
