You cannot use ROLLBACK to undo the effect; however, if an error occurs during statement execution, the statement is rolled back. Now, you know how the autocommit works, let's now shift our attention to how MySQL Connector/Python deals with the transaction. Example: Program to update the age of a student named Rishi Kumar and commit it to the database. Primary key support: Supported PK modes are kafka, none, and record_value. To roll back instead and discard modifications, see the C#. This is the reason, why we had to use the commit() method of the connection object to commit the changes.
