Selecting random record problem

Selecting random record problem

Hello,

I think that question was asked many times on the list but I searched
archives and found nothing suitable for me.

That's my problem: I need to select one (two, three...) random records from
a table.

Here's what I do:

SELECT * FROM banners ORDER BY RAND() LIMIT 1

It works for persistent connections BUT it returns the same record if the
connection is reestablished every time after running this query! (This takes
place is PHP scripts, for example.)

I also tried using sequence seed but that didn't help too:

SELECT * FROM banners ORDER BY RAND(NOW()) LIMIT 1

MySQL version is 3.23.

Any ideas?
