Ok - I'll see what that gives me. -----Original Message----- From: C. Hatton Humphrey [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 13, 2002 11:26 AM To: CF-Talk Subject: RE: Random row from SQL
Pulling the old BASIC memories out of the hat you could replace 100 with @@RowCount (not sure on syntax) so INT((RAND()*@@RowCount))... you'd want to add one to the result and subtract 1 from the rowcount to make sure you don't return out of bounds C.
