passing list to IN clause in HQL or SQL?

问题

I get List<Strings> by executing a query. This must be passed to another query of IN clause values. How to pass them in HQL?

We can convert List to Array and can pass it, that's not a problem.

Finally, I must pass the list in List<String> or Array or String form to the IN clause.

回答1:

from AUTOS a where a.model in (select m.model from MODELS m) 

or

Query query1 = session.createQuery("select s.id from Salary s where s.salary < 50000 AND s.salary > 49980");
Query query2 = session.createQuery("from Employee e where e.id in (:ids)").setParameterList("ids", query1.list());
query2.list();

I know it's been a while and you have been trying to pass the value of a different query as a queryParameter, you can also pass set or collections to in clause in HQL with 'elements()' - here's a simple example of such usage: Hibernate query: does a Set contains a certain Object?
