Hibernate version: 3.0

I am trying to get the following query to work:

Session session = HibernateAbstractSessionUtil.getCurrentSession();
Double query = (Double) session.createSQLQuery(
"SELECT SUM(postAmount) sumPostAmount " +
" FROM ( SELECT (CASE WHEN ENTRY_TYPE = 'DEBIT' THEN POST_AMOUNT ELSE POST_AMOUNT * -1 END) postAmount " +
" from S_GL_ENTRY_E11 ) e11")
.addScalar("sumPostAmount", Hibernate.DOUBLE)
.addScalar("postAmount", Hibernate.DOUBLE)
.uniqueResult();

sumOfPostAmounts = query.doubleValue();




The query works fine through my SQuirrel SQL client. But Hibernate is telling me about an invalid column name. Can someone suggest some ideas for me? Is this a driver issue?

The error message is as follows:

you call addScalar for a column that is not in the select.
