[jboss-user] [EJB 3.0] - how to write query for in select

[john_woo@canada.com]

Hi,

if table a (int av, varchar(10) an),
  table b (int bv, varchar(10) bn),

I want

select count(*) from a a where av in (select bv from b b where a.an = b.vn)

how to convert it into EJB QL using entityManager.createQuery?

Thanks

John
