ActiveRecord order by random broken on MySQL ?

[quote author="girv" date="1227047288"]I think explicitly using "RAND()" was deprecated a while ago in favour of using the "random" keyword, for better database independence in your code. It's RAND() on MySQL, but not on some other databases.

I agree with this, but I don't has enough time to replace this (and test) in huge codebase.
probably CI needed global config keys to make new versions backward compatible
