Answer 1

試試這個按照SQL SERVER

DECLARE @id VARCHAR(50)= '1,2,3', 
@Answer VARCHAR(50)= 'i,know,you', 
@a VARCHAR(50), 
@b VARCHAR(50); 

WHILE LEN(@id) > 0 
    BEGIN 
     SET @a = LEFT(@id, CHARINDEX(',', @id+',')-1); 
     SET @b = LEFT(@Answer, CHARINDEX(',', @Answer+',')-1); 

     INSERT INTO #temp 
     VALUES 
     (@a, 
     @b 
     ); 

     SET @id = STUFF(@id, 1, CHARINDEX(',', @id+','), ''); 
     SET @Answer = STUFF(@Answer, 1, CHARINDEX(',', @Answer+','), ''); 
    END; 
SELECT * 
FROM #temp; 
DROP TABLE #temp; 

Answer 2

這是正常的INSERT語句。

INSERT INTO questions (question_id,answer) VALUES ('1', 'one'); 
INSERT INTO questions (question_id,answer) VALUES ('2', 'two'); 
INSERT INTO questions (question_id,answer) VALUES ('3', 'three');
