NOT IN (select Emp_Code from EmployeeAllocation);

I was unable to find any solution for this on google. I dont know how to write NOT IN clause in HQL The result should must be fetched to a List. Like this:

I think you can do it like, As you haven't provided any information about the table structure, otherwise I would have suggested you some better query.

But here in the below shown query I am just trying to tell you about the NOT IN clause in Hibernate or hql.

list = select Emp_Code from EmployeeAllocation

Criteria criteria = DetachedCriteria.forClass(Employee.class);
criteria.add(Restrictions.not(Restrictions.in("Emp_Code", list);

return getHibernateTemplate().findByCriteria(criteria);
