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.
