是否可以在视图中调用存储过程? [英] Is it possible to call stored procedure in view?

问题描述

有人在此处询问了有关sql-server的类似问题.我想知道它是否可以在MySql中使用.

A similar question about sql-server has been asked here. I'm wondering if its possible in MySql.

我想在视图中使用从过程返回的结果集.

I want to use result set returned from procedure in view.

推荐答案

如果要获取结果集并在FROM子句中使用例程-否. MySQL中存储的例程(过程或函数)无法将表作为结果值返回.

If you want to get result-set and use routine in FROM clause - NO. Stored routines (procedures or functions) in MySQL cannot return tables as result value.

但是您可以将函数用作简单值，例如-

But you can use functions as simple values, for example -

DELIMITER $$

CREATE FUNCTION mul10(Param1 INT)
RETURNS INT(11)
BEGIN
  RETURN Param1 * 10;
END
$$

DELIMITER ;

CREATE OR REPLACE VIEW view1
AS
SELECT mul10(2) AS column1;

SELECT column1 FROM view1;
----------
20
