Question

Assuming that I want to write the following HQL query:

FROM Cat c WHERE c.id IN (1,2,3)

what is the proper way of writing this as a parametrized query, e.g.

FROM Cat c WHERE c.id IN (?)

Answer 1

I am unsure how to do this with positional parameter, but if you can use named parameters instead of positional, then named parameter can be placed inside brackets and setParameterList method from Query interface can be used to bind the list of values to this parameter.

...
Query query = session.createQuery("FROM Cat c WHERE c.id IN (:ids)");
query.setParameterList("ids", listOfIds);
