Hibernate native SQL

Native SQL refers to the real SQL for used database. Hibernate provides the facility to use native SQL. We can create a native SQL by createSQLQuery() method of Session interface.

Syntax of Hibernate native SQL which returns an object array:

Query query = session.createSQLQuery(“nativeSQL”);

Syntax of Hibernate native SQL which returns an entity:

Query query = session.createSQLQuery(“nativeSQL”).addEntity(entityName.class);

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
Last Name: Kunar
Class: MCA final
