怎样用SQL Server和c语言或C#编写个应用程序？比如说电话本
create table groups
(
g_id int identity(1,1) primary key,
g_name varchar(20),
up int
)
insert into groups values('显示所有组',1)
insert into groups values('显示所有用户',2)
select * from users
-- 组的存储过程
create procedure add_group
(
@g_name varchar(20),
@g_up int
)
as
begin
insert into dbo.groups (g_name,up) values(@g_name,@g_up)
end
select * from groups
alter procedure del_group
(
@id int
)
as
begin
declare @i int
select @i=g_id from groups where g_id = @id
delete groups where g_id = @i
declare @j int
select @j=count(*) from groups where up = @i
declare @h int
set @h =1
while(@h<=@j)
begin
declare @g int
select top(@h) @g=g_id from groups where up = @i
delete groups where g_id = @g
exec del_group1 @g
set @h = @h+1
end
end

C# ADO.net，看看就知道了，不是很难
C 就困难啊
