实现类似split功能(charindex)

create procedure sp_split_string


(


@string NVARCHAR(4000)


)


AS


BEGIN


DECLARE @object_id nvarchar(500)


DECLARE @i INT


DECLARE @len INT


print @string


IF (@string IS NULL) OR (LTRIM(@string) = '')


RETURN




WHILE CHARINDEX(',',@string) > 0


BEGIN


SET @len = LEN(@string)


SET @i = CHARINDEX(',', @string)


SET @object_id = LEFT(@string, @i-1)




INSERT INTO a (id) VALUES (@object_id)--少做修改，改成需要的sql语句即可


SET @string = RIGHT(@string, @len - @i)


END


SET @object_id = @string


INSERT INTO a (id) VALUES (@object_id)--少做修改，改成需要的sql语句即可


END


go




--测试


-- select * from a


-- exec sp_split_string '102,103,105,106,107,108,200,500,306,408'


-- select * from a
