解析逗号（，）字符串存储过程

Question

存储过程：

CREATE PROCEDURE lead_to_loan(xReffID_list text) 

我想用这个xReffID_list变量在SELECT语句中作为

SELECT * FROM XXXX where xreffID IN (xReffID_list); 

但xreffID是int可变

如何使用xReffID_list text这是的IN条件中的一串逗号分隔数字210个变量？

存储过程：

DELIMITER $$

CREATE PROCEDURE lead_to_loan(XRefID_list text)

Answer 1

您可以使用find_in_set做到这一点：

SELECT * FROM XXXX WHERE find_in_set(xreffID, xreffID_list) > 0 

Answer 2

嘿，你可以使用CAST（）函数可以与MySQL

希望这会帮助你。
