This confirms that hibernate was tracking the object for any changes and at the time of committing transaction, this value got saved. Hibernate Util; public class Hibernate Merge Example Hibernate: select employee0_.emp_id as emp_id1_1_0_, employee0_.emp_name as emp_name2_1_0_, employee0_.emp_salary as emp_sala3_1_0_, address1_.emp_id as emp_id1_0_1_, address1_.address_line1 as address_2_0_1_, address1_as city3_0_1_, address1_.zipcode as zipcode4_0_1_ from EMPLOYEE employee0_ left outer join ADDRESS address1_ on employee0_.emp_id=address1_.emp_id where employee0_.emp_id=? Id= 101, Name= Final updated name, Salary= 1000.0, false 15.

If we use this without transaction and we have cascading between entities, then only the primary entity gets saved unless we flush the session.

For our testing purposes we have two entity beans – package com.journaldev.hibernate.model; import javax.persistence.

After committing update transaction Hibernate: select employee0_.emp_id as emp_id1_1_0_, employee0_.emp_name as emp_name2_1_0_, employee0_.emp_salary as emp_sala3_1_0_, address1_.emp_id as emp_id1_0_1_, address1_.address_line1 as address_2_0_1_, address1_as city3_0_1_, address1_.zipcode as zipcode4_0_1_ from EMPLOYEE employee0_ left outer join ADDRESS address1_ on employee0_.emp_id=address1_.emp_id where employee0_.emp_id=? Id= 101, Name= Final updated name, Salary= 1000.0, 13. After committing update transaction Notice that there are no updates fired after first execution because there are no update in values. Also notice that in further execution, name is “Kumar”, this is because the returned object is tracked for any changes.

After committing merge transaction Notice that the entity object returned by merge() is different from the passed entity.

Let’s look at hibernate persist with a simple program.

Finally, persist doesn’t return anything so we need to use the persisted object to get the generated identifier value. Transaction; import com.journaldev.hibernate.model. With transaction employee object is tracked for any changes, thats why in last call there is no update in Employee table even though the value was changed in between, final value remains same. Transaction; import com.journaldev.hibernate.model. After committing save Or Update transaction ***** Notice that without transaction, only Employee gets saved and address information is lost. Hibernate Util; public class Hibernate Update Example Hibernate: select employee0_.emp_id as emp_id1_1_0_, employee0_.emp_name as emp_name2_1_0_, employee0_.emp_salary as emp_sala3_1_0_, address1_.emp_id as emp_id1_0_1_, address1_.address_line1 as address_2_0_1_, address1_as city3_0_1_, address1_.zipcode as zipcode4_0_1_ from EMPLOYEE employee0_ left outer join ADDRESS address1_ on employee0_.emp_id=address1_.emp_id where employee0_.emp_id=? ) ***** Hibernate: insert into EMPLOYEE (emp_name, emp_salary) values (? Before committing save transaction Hibernate: insert into ADDRESS (address_line1, city, zipcode, emp_id) values (? FIELD) public class Address package com.journaldev.hibernate.main; import org.hibernate.
