SQLSERVER 拆分拼接字符串

SQLSERVER 拆分拼接字符串，WHILE循环输出

DECLARE @Items VARCHAR(1000)
SET @Items='148,149,150,151' +',' 
DECLARE @ItemIndex INT
set @ItemIndex=CHARINDEX(',',@Items)
 
WHILE(@Items!=',' AND @ItemIndex>0)
BEGIN
    PRINT LEFT(@Items,@ItemIndex-1)
    SET @Items=RIGHT(@Items,LEN(@Items)-@ItemIndex)
    SET @ItemIndex=CHARINDEX(',',@Items)
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)
