Named queries and EJBQL

I�m trying to write a named query which uses an �in� query �
something like : select * from Drink d where name in (�coke�,�7up�,�)
I can�t use parameters, since I don�t know how many of them are.
Neither can I pass a string like �coke,7up,�� .

Any idea?

You can't use a named query for this. Your choices are to do the query one drink name at a time or to use a native SQL query.

You can pass multiple parameters as a list.

For example:

It works!
