Hibernate batch delete not working?

Question

I am trying to batch delete data from table . For that am setting parameter list for deletion.

    ArrayList<Integer> ids = new ArrayList<Integer>();
    ids.add(1);
    ids.add(2);
    ids.add(3);
    ids.add(4);

    Session session1 = sfactory.openSession();
    Transaction txn1 = session1.beginTransaction();

    Query query = session1.createQuery("delete from QueueData tbl where tbl.iID in =:id");
    query.setParameter("id", ids);

    int i = query.executeUpdate();
    txn1.commit();

I am getting exception while executing statement.

   SEVERE: line 1:61: unexpected token: =
   Exception in thread "main"
   org.hibernate.hql.ast.QuerySyntaxException:    
   unexpected token: = near line 1, column 61 [delete from

Answer 1

You should be aware of basic sql.

IN condition syntax

Your delete query should look like:

"delete from QueueData tbl where tbl.iID in (:id)"
