在MYSQL存储过程中循环选择查询结果集

Question

How to loop the resultset of query and in loop the resultset get the column value and fire insert query on database.

Below is My 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;

Then how to loop the stmt1 to get all ID values to insert in another table.

My 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

But it give error Subquery returns more than 1 row

Answer 1

Finally I've write stored procedure as:

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

Do the INSERT in the query:

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