Qu'arrive-t-il à la transaction MySQL en cours si une commande START TRANSACTION est exécutée au milieu de la transaction en cours ?

mysql> select * from marks; +------+---------+-----------+-------+ | Id | Name | Subject | Marks | +------+---------+-----------+-------+ | 1 | Aarav | Maths | 50 | | 1 | Harshit | Maths | 55 | | 3 | Gaurav | Comp | 69 | +------+---------+-----------+-------+ 3 rows in set (0.00 sec) mysql> START TRANSACTION; Query OK, 0 rows affected (0.00 sec) mysql> INSERT INTO Marks Values(4, 'Rahul','History',40); Query OK, 1 row affected (0.00 sec) mysql> INSERT INTO Marks Values(5, 'Yashraj','English',48); Query OK, 1 row affected (0.00 sec) mysql> START TRANSACTION; Query OK, 0 rows affected (0.00 sec)
