How To End the Current Transaction?

There are several ways the current transaction can be ended implicitly or explicitly:

• In "Autocommit On" mode, a single-statement transaction will be ended implicitly when the execution of the statement ends. Changes will be committed.
• Running the COMMIT command will explicitly end the current transaction. Changes will be committed.
• Running the ROLLBACK command will explicitly end the current transaction. Changes will be rolled back.
• Running the START TRANSACTION command will explicitly end the current transaction. Changes will be committed.
• Running any DDL statement will implicitly end the current transaction. Changes will be committed.
• Disconnecting a client session will implicitly end the current transaction. Changes will be rolled back.
• Killing a client session will implicitly end the current transaction. Changes will be rolled back.
