1.存储过程实现

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 a2.一个用于处理分隔","的函数tf_split_str
--1. 建立测试数据
--1.1 create table TypeAdv
CREATE TABLE TypeAdv
(
    id int,
    TypeName varchar(200)
)
--1.2 insert data
insert into TypeAdv(id,TypeName) values(1,'电脑网络')
insert into TypeAdv(id,TypeName) values(2,'游戏动漫')
insert into TypeAdv(id,TypeName) values(3,'软件下载')
insert into TypeAdv(id,TypeName) values(4,'商务商铺')
insert into TypeAdv(id,TypeName) values(5,'建站服务')
insert into TypeAdv(id,TypeName) values(6,'门户综合')
insert into TypeAdv(id,TypeName) values(7,'影视音乐')
insert into TypeAdv(id,TypeName) values(8,'休闲娱乐')
insert into TypeAdv(id,TypeName) values(9,'生活资讯')
insert into TypeAdv(id,TypeName) values(10,'文学小说')
   
--1.3 create table TypeAdv
CREATE TABLE GroupAdv
(
    id int,
    GroupName varchar(200),
    IntentionSet varchar(200)
)
--1.4 insert data
insert into GroupAdv(id,GroupName,IntentionSet) values(5,'广告分组一','1,2,3,4,5,6,7,10')
insert into GroupAdv(id,GroupName,IntentionSet) values(6,'广告分组二','1,2,3,4,5,6')
--2. 创建分隔“，”的函数
CREATE FUNCTION tf_split_str
(
    @string        NVARCHAR(4000)
)
RETURNS varchar(4000)
AS
BEGIN
    DECLARE @object_id     nvarchar(400)
    DECLARE    @i          INT
    DECLARE    @len        INT
    declare @return     varchar(400)
    set @return=''

    IF (@string IS NULL) OR (LTRIM(@string) = '')
        RETURN @return
   
    WHILE CHARINDEX(',',@string) > 0
        BEGIN
            SET @len = LEN(@string)
            SET @i = CHARINDEX(',', @string)
            SET @object_id = LEFT(@string, @i-1)
            select @return = @return+','+TypeName from TypeAdv where id = @object_id
            SET @string = RIGHT(@string, @len - @i)

        END

    SET @object_id = @string
    select @return = @return+','+TypeName from TypeAdv where id = @object_id
    set @return = stuff(@return,1,1,'')
    RETURN @return
END
--3.测试
select b.id,b.GroupName,dbo.tf_split_str(b.IntentionSet) from GroupAdv b
