I have a following HQL query: SELECT s.id FROM stack s WHERE s.category is not empty

Basically, s.category is a one-to-many join to another table (Category). I need to check whether the collection is empty or no. I can do it in c# code (just run through all of the Stacks and check if Stack.category.count > 0. Is there any HQL way to do so?

Thank you!

I think this syntax works here:

from stack s where exists elements(s.category)
