我們如何在mysql中使用commit，rollback和savepoint？

Answer 1

CREATE TABLE t_test (id INT NOT NULL PRIMARY KEY) ENGINE=InnoDB; 

START TRANSACTION; 

INSERT 
INTO t_test 
VALUES (1); 

SELECT * 
FROM t_test; 

id 
--- 
    1 

SAVEPOINT tran2; 

INSERT 
INTO t_test 
VALUES (2); 

SELECT * 
FROM t_test; 

id 
--- 
    1 
    2 

ROLLBACK TO tran2; 

SELECT * 
FROM t_test; 

id 
--- 
    1 

ROLLBACK; 

SELECT * 
FROM t_test; 

id 
--- 

Answer 2

mysql> start transaction; 
mysql> savepoint id; 

在這裏，您更改表數據，然後：

mysql> rollback to savepoint id; 

視圖中的數據和最後：

mysql> release savepoint id;
