Hibernate 4 ReturningWork and Session.doReturningWork Example for JDBC

By Arvind Rai, February 12, 2015
In this page we will learn Hibernate 4 ReturningWork and Session.doReturningWork example for JDBC. From hibernate session java connection object will be created and using JDBC interact to database and return the result. org.hibernate.jdbc.ReturningWork has execute() method that has argument as java Connection. To use in our hibernate program, there is a method in hibernate Session as given below.
<T> T	doReturningWork(ReturningWork<T> work) 


org.hibernate.jdbc.ReturningWork interacts through JDBC to fetch data from database and then return it. The JDBC connection instance is provided by hibernate. ReturningWork has a method as below.

T execute(Connection connection): This method is implemented to interact with database using JDBC. The Connection argument is provided by hibernate. Using this connection, we can fetch java PreparedStatement, CallableStatement and Statement. Finally return the data.


org.hibernate.Session.doReturningWork is the method which accepts argument of hibernate ReturningWork. After completing the work, the object retuned by ReturningWork is finally returned to calling doReturningWork.
