I have problem to utilize saveOrUpdate() method,

i have table user which is having columns name, address and id which is generated by hibernate Auto.

i wanna save first

(Mohan, BTM) == in DB (1, Mohan, BTM) it's working fine

i wanna update the same record in DB(1, Mohan, EC).

Instead of saving like this save or update method is creating one more row like

2 , mohan, EC.

Plz clarify my doubt .

'saveOrUpdate() ' method create a new row when ID field of object is null.

Please check id field value before caling 'saveOrUpdate() ' method. In case ID field is blank set appropriate id value in it.
