Answer 1

经过多次尝试后，我发现IN()取代FIND_IN_SET()，而DELIMITER $$ USE `employee`$$ DROP PROCEDURE IF EXISTS `selectemployeebyids`$$ CREATE DEFINER=`root`@`localhost` PROCEDURE `selectemployeebyids`(IN empid VARCHAR(100)) BEGIN SELECT empname,salary,department from emp where empid FIND_IN_SET(empid) ORDER BY empid; END$$ DELIMITER ; 适用于我。

Answer 2

试试这个

DELIMITER $$ 

USE `employee`$$ 

DROP PROCEDURE IF EXISTS `selectemployeebyids`$$ 

CREATE DEFINER=`root`@`localhost` PROCEDURE `selectemployeebyids`(IN empid_in VARCHAR(100)) 
BEGIN 
    SELECT empname,salary,department from emp 
        where concat(',',empid_in,',') like concat('%,'cast  (empid as varchar(10)),',%')
        ORDER BY empid; 
   END$$ 


 DELIMITER ;
