在MYSQL存储过程中循环选择查询结果集

Question

如何循环查询结果集和循环结果集以获取列值并在数据库上执行插入查询。

以下是我的SP：

Input parameter listvalues and value is 1,2,3,4,5

SET @t1 = CONCAT("SELECT ID FROM interest WHERE ID IN(",listvalues,")");
PREPARE stmt1 FROM @t1;
EXECUTE stmt1;
DEALLOCATE PREPARE stmt1;

然后如何循环stmt1以获得所有ID值以插入到另一个表中。

我的SP：

BEGIN 
INSERT INTO `registration`(`FirstName`,`LastName`,`EMail`,`PhoneNumber`,`Gender`,`State`,`City`,`ImagePath`,`IsDeleted`,`CreatedDate`,`ModifiedDate`)
VALUES(FirstName,LastName,EMail,PhoneNumber,Gender,State,City,ImagePath,0,NOW(),NOW());

SET @RegID = LAST_INSERT_ID();

SET @t1 = CONCAT("INSERT INTO `userinterest` (`InterestId` , `UserId`) VALUES((SELECT ID FROM interest WHERE ID IN(",InterestList,")),",@RegID,")");
PREPARE stmt3 FROM @t1;
EXECUTE stmt3;
DEALLOCATE PREPARE stmt3;

END

但是它给错误子查询返回超过1行

Answer 1

最后，我将存储过程编写为：

BEGIN 
INSERT INTO `registration`(`FirstName`,`LastName`,`EMail`,`PhoneNumber`,`Gender`,`State`,`City`,`ImagePath`,`IsDeleted`,`CreatedDate`,`ModifiedDate`)
VALUES(FirstName,LastName,EMail,PhoneNumber,Gender,State,City,ImagePath,0,NOW(),NOW());

SET @RegID = LAST_INSERT_ID();

SET @t1 = CONCAT("INSERT INTO `userinterest` (`InterestId` , `UserId`) SELECT ID AS InterestId, ",@RegID," AS UserId FROM interest WHERE ID IN(",InterestList,")");
PREPARE stmt3 FROM @t1;
EXECUTE stmt3;
DEALLOCATE PREPARE stmt3;

END

Answer 2

在查询中执行INSERT ：

SET @t1 = CONCAT("INSERT INTO otherTable (interest_id)
                  SELECT ID FROM interest WHERE ID IN(",listvalues,")");
