在MYSQL存儲過程中循環選擇查詢結果集

Question

如何循環查詢結果集和循環結果集以獲取列值並在數據庫上執行插入查詢。

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;

然后如何循環stmt1以獲得所有ID值以插入到另一個表中。

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

但是它給錯誤子查詢返回超過1行

Answer 1

最后，我將存儲過程編寫為：

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

在查詢中執行INSERT ：

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