SQLSERVER 拆分拼接字符串

SQLSERVER 拆分拼接字符串，WHILE循环输出

 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

拆分字符串并插入临时表

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)
