SQLSERVER 拆分拼接字符串，WHILE循環輸出
1 DECLARE @Items VARCHAR(1000) 2 SET @Items='148,149,150,151' +',' 3 DECLARE @ItemIndex INT 4 set @ItemIndex=CHARINDEX(',',@Items) 5 6 WHILE(@Items!=',' AND @ItemIndex>0) 7 BEGIN 8 PRINT LEFT(@Items,@ItemIndex-1) 9 SET @Items=RIGHT(@Items,LEN(@Items)-@ItemIndex) 10 SET @ItemIndex=CHARINDEX(',',@Items) 11 END
拆分字符串並插入臨時表
declare @s varchar(100),@sql varchar(1000) set @s='1,2,3,4,5,6,7,8,9,10' set @sql='select col='''+ replace(@s,',',''' union all select ''')+'''' PRINT @sql exec (@sql)
