如何在触发器MYSQL内将变量设置为存储过程的结果? [英] How to set a variable to the result of a stored procedure inside a Trigger MYSQL?

问题描述

我在这里有一个小问题，我正在为数据库工作创建一个触发器，但是我不知道如何在触发器中使用存储过程，我想将过程的结果保存在变量中，然后稍后在IF比较器上使用该变量，这是我的代码:

I have a little problem here, I'm making a trigger for my DB work, but I don't know how to use a stored procedure inside a trigger, I want to save the result of the procedure in a variable and then use the variable later on an IF comparator, this is my code:

DELIMITER @
CREATE TRIGGER insert_players AFTER INSERT ON players FOR EACH ROW
BEGIN
DECLARE A varchar(50);
set A = CALL consult_sex(player_name); //I WANT SOMETHING LIKE THIS
IF A != FEMALE THEN
INSERT INTO males (id_player, player_fullname, player_celphone)
VALUES (new.id_player, concat(new.player_name, " ", new.player_lastname), new.player_phone);
END IF; 
END;

Could someone help me with this doubt? Would be wonderfull, thanks.

推荐答案

让您的过程采用OUT参数，例如

have your procedure take a OUT parameter like

CREATE PROCEDURE consult_sex(player_name VARCHAR(20), OUT player_sex VARCHAR(10))

在您的过程SET中，值

SET player_sex = <your query to get sex>

通过参数调用过程

call consult_sex(player_name, @out_value);
select @out_value;
