 Post subject: CASE statement not supported in SQL count function?

Good evening,
I need to execute a query using something like (SQL is obviously simplified a lot to focus on issue - I need count(distinct CASE..) combo)

select count(distinct (CASE WHEN obj.id < 1000 then 1 else null) )
from object obj

Stack trace is below.

The equivalent runs fine in SQL as aggregate functions support case statement.
select count(distinct (CASE WHEN ID < 1000 THEN 1 ELSE 0 END))
from TABLE

This looks like a bug in the parser?

Use session.createSQLQuery() and then query.setEntity() when you need to use SQL code that has no HQL equivalent.
