Difference between Hibernate createCriteria, createQuery, createSQLQuery functions

Question

Can anyone please tell me the difference between Hibernate\'s:

• createCriteria
• createQuery
• createSQLQuery

Answer 1

1. session.createQuery()-> Can create query using HQL and can perform CRUD Operations 

Example:

      Query query = session.createQuery("from Student");
      List list=quey.list();

      Query query = session.createQuery("update Student where studentid=9");
      int result=query.executeUpdate();

      Query query = session.createQuery("delete Student where studentid="+ studentId);
      int result=query.executeUpdate();

      Query query = session.createQuery("insert into Student where studentid="+ studentId);
      int result=query.executeUpdate();

2. session.createSQLQuery()-> Can create query using SQL and can perform CRUD Operations
3. session.createCriteria()->Can create query using Criteria API and can perform only Read Operations
