Multiple column selection using EJB-QL

I want to select multiple columns through EJB-QL, but whenever i write that
it gives an exception saying it was expecting 'from' instead of ','.
EJB-QL is like as follows:
select m1.code, m1.text from DROP_VALUE m1 where lang=?1
Home method for this is having return type as 'Collection'
Can you please tell can we select multiple columns at a time or not throgh EJB-QL and if yes, then how todo that.

implies that it should be possible.
I haven't tried it though and would recommend just returning m1 (the whole entity) if you having problems.
