Query works in phpMyAdmin but not with CI Active Record in php

What is the definition of 'work' and 'not work'? Error messages? Unexpected behaviour?
What database engine are you using?

This should result in

Code:

UPDATE `MyTable` SET `MyBooleanValue` = 0 WHERE `ID1` = '$id1' AND `ID2` = '$id2'

which looks fine to me...
