JPA Entity Bulk Delete not working

I have three related entities

public class EntityA
{
private Long id;
}


public class EntityB
{
private Long id;
private EntityA entityA;
private EntityC entityC;

}

public class EntityC
{
private Long id;
}

Query query = persistenceManager.createNamedQuery("DELETE FROM EntityB a WHERE a.entityA = :entityA AND a.entityC.id in :entityCList"); query.setParameter("entityA", entityAObj); query.setParameter("entityCList", entityCList); query.executeUpdate();

I am using MySQL database. The parameter :entityCList is an ArrayList of entityC ids i.e. List<Long> entityCList and :entityA is an Object of EntityA.

When i ran the delete query above, the records did not delete from the database and it did not throw an exception. What could be wrong with the query.

What was the SQL generated?

Try comparing entityC to a list of EntityC objects instead of ids.

Or, try using a sub-select, instead of a join.
