mysql – ERROR 1305(42000)：SAVEPOINT …不存在

我在我的MYSQL DB中有这个SQL(sproc有空体,所以我猜没有隐式提交？).

DROP PROCEDURE IF EXISTS doOrder;

DELIMITER $$

CREATE PROCEDURE doOrder(IN orderUUID VARCHAR(40))
  BEGIN
    SAVEPOINT sp_doOrder;

    BEGIN
      DECLARE EXIT HANDLER FOR SQLEXCEPTION ROLLBACK TO sp_doOrder;

      -- doing my updates and selects here...

    END;

    RELEASE SAVEPOINT sp_doOrder;
  END $$

DELIMITER ;

当我

call doOrder('some-unique-id');

我得到：ERROR 1305(42000)：SAVEPOINT sp_doOrder不存在.

我可能会忽略一些事情……任何想法？

解决方法:

您必须使用START TRANSACTION而不是BEGIN来启动存储过程中的事务.

此外,您可能需要将SAVEPOINT语句移动到DECLARE之后(取决于您放置START TRANSACTION的位置)

Note

Within all stored programs (stored procedures and functions, triggers,
and events), the parser treats BEGIN [WORK] as the beginning of a
BEGIN … END block. Begin a transaction in this context with START
TRANSACTION instead.
