SQL server select random rows

Code:
SELECT TOP n *
FROM            <table>
WHERE        <filter>
ORDER BY NEWID()


Please note that ORDER BY NEWID() will be very expensive for large result sets because it has to generate an id for every row, and then sort them.

You can also select top n percent.
