Question

我有两个表公司（id，company_name）和用户（id，company_id，user_name）;

现在我想在公司表中插入数据时创建一个视图。

我使用了以下两种方法但在两种情况下都得到了相同的错误。错误是：

#1422 - Explicit or implicit commit is not allowed in stored function or trigger.

第一个查询是：

DELIMITER $$
CREATE TRIGGER testInsert 
    AFTER INSERT ON companies
    FOR EACH ROW BEGIN

   CREATE VIEW test(user_name) AS 
    SELECT user_name
    FROM users;
END$$
DELIMITER ;

然后我尝试首先创建过程并在触发器中调用该过程，如此

create procedure createView() 
 create view vt as select * from users; 


 CREATE TRIGGER `testInsert3` AFTER INSERT ON `companies`
FOR EACH ROW
BEGIN
   CALL createView();
END;

请帮帮我们。

全部谢谢。

try creating the view like this 


DELIMITER $$
CREATE TRIGGER testInsert 
    AFTER INSERT ON companies
    FOR EACH ROW BEGIN

   EXECUTE('CREATE VIEW test(user_name) AS SELECT user_name
    FROM users')
END$$
DELIMITER ;

插入触发器后创建视图
