我怎样才能创建一个程序select语句在'IN子句'phpmyadmin

Question

我想创建一个选择查询的where子句将有一个IN子句的过程。我创造了一个过程像下面butu它不是working-

CREATE DEFINER = `root`@`localhost` PROCEDURE `agentin` (IN `code` VARCHAR(100)) NOT DETERMINISTIC NO SQL SQL SECURITY DEFINER 
BEGIN 
SELECT * FROM AgentInformation WHERE AgentCode IN (code); 
END 

把在子句值等之后 - > IN（“CG001”，“CG002”）

我得到空值和通过的phpmyadmin制成查询是

SET @p0 = '''CG001'',''CG002'''; 

CALL agentin（ @ P0 ）;

把它请帮帮忙，谢谢

Answer 1

这是一个例子 -

DELIMITER $$ 

CREATE PROCEDURE procedure1(IN id_param VARCHAR(255)) 
BEGIN 
    SET @sql = CONCAT('SELECT * FROM table WHERE id IN (', id_param, ')'); 
    PREPARE stmt FROM @sql; 
    EXECUTE stmt; 
    DEALLOCATE PREPARE stmt; 
END$$ 

DELIMITER ; 

SET @id = '1,2,3,4,5'; 
CALL procedure1(@id);
