Hibernate Query Language (HQL) is an object-oriented query language, similar to SQL, but instead of operating on tables and columns, HQL works with persistent objects and their properties. Open the Advanced Filter dialogue box in the Data tab (located in the Sort & Filter tools group). Criteria api select clause can be used to select whole entities, single expression or multiple expressions.
