We said to ORDER by the rand() or newID() functions (depending on the platform)... rand() for MySQL and newID() for SQL Server
Select top 20 * field from table order by rand() Select top 20 * field from table order by newID() Try them. :-) -----Original Message----- From: Bader, Terrence C CTR MARMC, 231 [mailto:[EMAIL PROTECTED] Sent: Monday, April 02, 2007 10:52 AM To: CF-Talk Subject: RE: How to Random Pick records from a 10k record table via SQL when I use select top 20 ID, rand() as oID from table order by oID I get the 20 rows all with the same oID and basically all in a row; not so random. When I use newID instead, I get records from all over my 10k populated table.
