Question

我遇到了以下问题：

我有表'问题'（question_id，answer），其中有两列都是varchar。

输入值类似于（'1,2,3'，'一，二，三'）我需要插入查询，我希望值插入：

1 one 
2 two
3 three

提前致谢。

Answer 1

按照SQl服务器

尝试此操作

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

这是正常的插入声明。

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');

Answer 3

SET @var1 = '1,2,3' ;
SET @var2 = 'one,two,three' ; 

DROP TEMPORARY TABLE IF EXISTS temp1; 
CREATE TEMPORARY TABLE temp1( id INT NOT NULL AUTO_INCREMENT PRIMARY KEY , Question_Id int );

DROP TEMPORARY TABLE IF EXISTS temp2;
CREATE TEMPORARY TABLE temp2( id INT NOT NULL AUTO_INCREMENT PRIMARY KEY , Answer VARCHAR(10) );
SET @SQL1 = CONCAT("insert into temp1 (Question_Id) values ('", REPLACE(( @var1 ), ",", "'),('"),"'); " );
SET @SQL2 =  CONCAT("insert into temp2 (Answer) values ('", REPLACE(( @var2), ",", "'),('"),"'); ");

PREPARE stmt1 FROM @SQL1;
EXECUTE stmt1;

PREPARE stmt1 FROM @SQL2;
EXECUTE stmt1;

DEALLOCATE PREPARE stmt1;

select Question_Id, Answer FROM temp1 inner join temp2 on temp1.id = temp2.id
