Build Identifier: 

As IF(cond, exp1, exp2) function is MySQL specific, we should replace it with
CASE WHEN cond THEN exp1 ELSE exp2 END, which is supported by all major
databases (see bug 182136).
The patch will follow

Reproducible: Always
Steps to Reproduce:
Since when does MySQL support it?

"CASE was added in MySQL 3.23.3"  (see
http://dev.mysql.com/doc/mysql/en/Control_flow_functions.html). I think we
currently require 3.23.3 or higher, right?
yeah, just found that in the changelog myself before coming back here.  How
interesting.

Yes, we currently require 3.23.41 or newer, so that shouldn't be a problem at all.

(Although I do think IF() is easier to read, but compatibility rules...)
