This works

hql = "from State where StateCode like 'T%'";
Query query = session.createQuery(hql);

This does not

hql = "from State where StateCode like :StateCode";
Query query = session.createQuery(hql);
query.setParameter("StateCode", "T%");

I get this

1568 [main] DEBUG org.hibernate.hql.ast.ErrorCounter  - throwQueryException() : no errors
1596 [main] DEBUG org.hibernate.hql.antlr.HqlSqlBaseWalker  - select << begin [level=1, statement=select]

1611 [main] DEBUG org.hibernate.hql.ast.tree.FromReferenceNode  - Resolved :  {synthetic-alias}.StateCode -> state0_.StateCode
SELECT Exception: java.lang.reflect.UndeclaredThrowableException

Notice the UndeclaredThrowableException exception.

What am I doing wrong?

The database is SQL Server 2008 if that helps. But like I said, other queries work just fine.

Thanks
