MySQL 相当于 MS SQL 的 TRIGGER_NESTLEVEL()？

Question

我正在将我的数据从 SQLSERVER 迁移到 MySQL。我在为 TRIGGER_NESTLEVEL().

寻找替代函数时遇到了一些麻烦

MySQL 中 TRIGGER_NESTLEVEL() SQLSERVER 函数的等价物是什么（递归结束时触发）。如果没有，我如何检测递归是否以另一种方式结束？

这是我的查询：

ALTER TRIGGER [dbo].[TGR_UPD_NAME] 
ON [dbo].[TBL_MS_NAME] FOR UPDATE,INSERT 
AS 
BEGIN
    IF ((SELECT TRIGGER_NESTLEVEL()) > 1 )
    RETURN

    /* SOME UPDATE QUERY */
END

Answer 1

MySql 不做递归。期间.

来自 docs:

Stored functions cannot be used recursively.

Within a stored function or trigger, it is not permitted to modify a table that is already being used (for reading or writing) by the statement that invoked the function or trigger.
