-----------------------------------

I love this patch and it works good!
Actually, I had a problem with the query like followings and it also works well
now
{noformat}
select col1 from table1 where (case when col1 = '2014-03-21' then 1 else 0 end
IN (1) )
{noformat}
> Error occurs when FUNCTION and IN statement are used together.
