Question

I am trying to build query in Play framework, I have

select * from Candidate c where (:schools member of c.schools) 

After I bind :school with List with one element it returns result, but if I bind List with multiple elements nothing happens.

Caused by: org.hibernate.hql.ast.QuerySyntaxException: unexpected AST node: {vector} [select c from models.Candidate c where (:schools0_, :schools1_ member of c.schools)  group by c.id order by RAND()]

Actually I need something like

select * from candidate where schools in (x,x,x,x,x);

Relation between candidate and school is in linked table.

Is there any way to bind multiple values?

With Hibernate, you can also use directly the list itself.

select c from Candidate c join c.schools as school where school.id in (:schools)

The type of the :schools parameter is typed according to your ids, for example List<Int> or List<Long>.
