Hi,

I wanna use "case ... when...else...end" in query, I found in the document it is said supported, but i had no luck to make it work. The query i made is:

Code:
"Select t.id" +
                        t.nameCN, " +
                        "case when t.checked=1 then '是' else '否' end," +
                        "t.checked "+
                        "from Types t where t.carSerie.brand.manufacturer.id=? order by t.id"


Did anyone ever use this? Please help me out. THanks a lot.

No - case is not supported by all databases. Move this into the Domain object or you could use a property with a formula.

Actually case is now supported on most DBs, and in HQL. But not yet in the select clause (there is an existing JIRA request for that).
