If you are using MySQL try looking at this page for the function rand(): http://www.mysql.com/doc/M/a/Mathematical_functions.html
Here's a little overview of what it says: "In MySQL Version 3.23, you can, however, do: SELECT * FROM table_name ORDER BY RAND() This is useful to get a random sample of a set SELECT * FROM table1,table2 WHERE a=b AND c<d ORDER BY RAND() LIMIT 1000. Note that a RAND() in a WHERE clause will be re-evaluated every time the WHERE is executed. RAND() is not meant to be a perfect random generator, but instead a fast way to generate ad hoc random numbers that will be portable between platforms for the same MySQL version. " Cheers!
