Hibernate HQL Query : How to set a Collection as a named parameter of a Query?

Question

Given the following HQL Query:

FROM
    Foo
WHERE
    Id = :id AND
    Bar IN (:barList)

I set :id using the Query objects' setInteger() method.

I would like to set :barList using a List of objects, but looking at the Hibernate documentation and list of methods I cannot see an obvious choice of which to use. Any ideas?

Answer 1

I'm not sure about HQL, but in JPA you just call the query's setParameter with the parameter and collection.

Query q = entityManager.createQuery("SELECT p FROM Peron p WHERE name IN (:names)");
q.setParameter("names", names);

where names is the collection of names you're searching for

Collection<String> names = new ArrayList<String();
names.add("Joe");
names.add("Jane");
names.add("Bob");

Answer 2

Use Query.setParameterList(), [Javadoc here][1].

There are four variants to pick from.
