Hibernate named query using annotation

Named query is a concept of using queries by name. First a query is defined and a name is assigned to it. Then it can be used anywhere by this alias name.

Syntax of hibernate named query using annotation:

    @NamedQuery(name = " queryName ", query = " queryString ")

How to call a named query?

We can call the named query by getNamedQuery() method of Session interface.
Query query = session.getNamedQuery(“queryName”);

Hibernate: select hibernate_sequence.nextval from dual
Hibernate: insert into Student (First_Name, Last_Name, Class, 
RollNo, Age, Student_Id) values (?, ?, ?, ?, ?, ?)
Hibernate: select student0_.Student_Id as Student1_0_, 
student0_.First_Name as First2_0_, student0_.Last_Name as 
Last3_0_, student0_.Class as Class0_, student0_.RollNo as 
RollNo0_, student0_.Age as Age0_ from Student 
student0_ where student0_.RollNo=?
First Name: Sunil
