存储过程中实现类似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
10

print @string
11

IF (@string IS NULL) OR (LTRIM(@string) = '')
12

RETURN

WHILE CHARINDEX(',',@string) > 0
15

BEGIN
16

SET @len = LEN(@string)
17

SET @i = CHARINDEX(',', @string)
18

SET @object_id = LEFT(@string, @i-1)
19


20

INSERT INTO a (id) VALUES (@object_id)--少做修改，改成需要的sql语句即可
21

SET @string = RIGHT(@string, @len - @i)
22

END
23

SET @object_id = @string
24

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

END
