There’s also a theoretical PROD() aggregate function that is not actually implemented in most database servers.

I coded it once for MySQL server but it had some test fails that I couldn’t track down with the spare time I had available. I still have the diff here though (just checked&found, was for MySQL 4.1 in 2003/2004). I can see if I can add it into 5.1 without fuss, and otherwise hand it to someone who can look at it in more detail.
