After begining the transaction for a particular session the Selection query is coming properly in hibernet. but incase of updation, when trying to commit the transaction instead of update query is not coming. We are able to fetch data but unable to update.

From a public function we are calling three private functions.
Each one of them having different functionalities but main goal is the updation of data.
After writing commit statement it is displaying the transaction has been commited. But in true sense it is not.And the table we are trying to update is not having any primary key.
