Difference between HQL and Criteria Query in Hibernate

Hibernate » On Jul 14, 2011 | { 11 Comments }

Let us see the main differences between HQL and Criteria Query

  • HQL is to perform both select and non-select operations on the data,  but Criteria is only for selecting the data, we cannot perform non-select operations using criteria
  • HQL is suitable for executing Static Queries, where as Criteria is suitable for executing Dynamic Queries
  • HQL doesn’t support pagination concept, but we can achieve pagination with Criteria
  • Criteria used to take more time to execute then HQL
  • With Criteria we are safe with SQL Injection because of its dynamic query generation but in HQL as your queries are either fixed or parametrized, there is no safe from SQL Injection.

    @ramu :-) you bet, thanks for your feedback

  3. Ram says:

    I wont agree with pagination concept given by you
    please refer below
    Hibernate APIs provide few methods to set the pagination citerias in the query. We can use bothe normal Query and Criteria API. Look into the following code for how to create pagination using the Query object:

    Query query = session.createQuery(“from Studenet s”);
    For Criteria :

    Criteria criteria = session.createCriteria(Student.class);
    List result = criteria.list();

    Can u please explain select and non-select operations with example in both hql and criteria queries.i am nt clear with the above statement.


  6. puglist says:

    “HQL is suitable for executing Static Queries”. HQL is also suitable for executing dynamic

    queries by using Query.setParameter()mthod. In that method we can able to pass the values

    at run how we can able to say HQL is suitable to execute static query?.
