session.createQuery("Select attribute from GoodsSection tgs " +
    "join gs.ascendants ags join ags.attributes attribute " +
    "where attribute.outerId = :outerId and tgs = :section ")
.setString("outerId", pOuterId)
.setEntity("section", section)
.setMaxResults(1)
.uniqueResult();

Looks fine to me, but the result is

java.lang.IllegalStateException: No data type for node: org.hibernate.hql.ast.tree.IdentNode

Why? What's wrong?

You haven't defined the "gs" alias. You only have "ags" and "tgs".

Damn, you're right, shame on me!

To be fair, that's a royally crap error message. Only Oracle could produce a less helpful message.

That is a hibernate error... nothing to do with Oracle?

Who said anything about Oracle?
