What is the method for implementing transactions in MySQL?

In MySQL, you can achieve transactions using the following methods:

1. Begin, commit, and roll back transactions using the START TRANSACTION, COMMIT, and ROLLBACK statements.

START TRANSACTION;  -- 开始事务
-- 执行一系列的操作
COMMIT; -- 提交事务

START TRANSACTION; -- 开始事务
-- 执行一系列的操作
ROLLBACK; -- 回滚事务

1. Use SET autocommit=0 to disable the auto-commit feature, so that when executing SQL statements, transactions are not automatically committed. You will need to manually use COMMIT to commit transactions or use ROLLBACK to rollback transactions.

SET autocommit=0; -- 禁用自动提交
-- 执行一系列的操作
COMMIT; -- 提交事务

SET autocommit=0; -- 禁用自动提交
-- 执行一系列的操作
ROLLBACK; -- 回滚事务

1. Use SAVEPOINT and ROLLBACK TO statements to create savepoints and perform local rollbacks.

SAVEPOINT savepoint_name; -- 设置保存点
-- 执行一些操作
ROLLBACK TO savepoint_name; -- 回滚到保存点

The methods outlined above in MySQL allow for ensuring that a sequence of operations either all successfully commit or all rollback.
