SQL语句如下：
DECLARE @temp varchar(50)
DECLARE @post int
DECLARE @endpost int
DECLARE @flag bit
SET @flag = 1
SET @post = 0
SET @temp='1,2,3,4,'
WHILE(@flag = 1)
BEGIN
SET @endpost = charindex(',',@temp)
IF(@endpost > 0)
BEGIN
INSERT INTO [str] (chr) VALUES (substring(@temp,1,@endpost-1))
SET @temp = right(@temp,len(@temp)-@endpost)
END
ELSE
BEGIN
IF(@temp <> '')
BEGIN
INSERT INTO [str] (chr) VALUES (@temp)
SET @flag = 0
END
ELSE
SET @flag = 0
END
END
我使用的是下面这个版本
BEGIN
declare spot SMALLINT;
declare TId int;
WHILE (CampaignId_Array <> '') DO
SET spot=instr(CampaignId_Array,',');
IF spot > 0
THEN
SET TId = Cast(LEFT(CampaignId_Array, spot-1) as SIGNED);
SET CampaignId_Array = RIGHT(CampaignId_Array, LENGTH(CampaignId_Array)-spot);
ELSE
SET TId = Cast(CampaignId_Array as SIGNED);
SET CampaignId_Array = '';
END IF;
Insert into campaign_asset (campaign_id, asset_id, advertiser_id,created_by)
values (TId, Asset_id, Advertiser_id, Created_by);
END WHILE;
END
实际使用
DECLARE spot SMALLINT; -- 分隔符的位置
DECLARE tempCid VARCHAR(64); -- 循环插入到表tb_sc_tmrecive需要用到的临时的Cid
-- 这里要对 ClassId_Array 进行循环了，进行,分隔循环insert到表`tb_sc_tmrecive`来
WHILE (ClassId_Array <> '') DO
SET spot=INSTR(ClassId_Array,',');
IF spot > 0
THEN
SET tempCid = LEFT(ClassId_Array, spot-1) ;
SET ClassId_Array = RIGHT(ClassId_Array, LENGTH(ClassId_Array)-spot);
ELSE
SET tempCid = ClassId_Array ;
SET ClassId_Array = '';
END IF;
INSERT INTO `tb_sc_tmrecive`(`MId`,`CId`) VALUES (intId,tempCid); -- 循环了每个班级id，插入到表 tb_sc_TMRecive
END WHILE;
-- 分隔插入结束
