关于学生按分数排列名次的问题
把学生的分数按从高到低的顺序进行排序，然后产生排名的，所以没有引用任何参数。
-------代码开始--------
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_NULLS ON
GO
create procedure up_get_sort AS
declare @ll_sort int,
@ldc_value dec(9,2),
@ls_id varchar(16),
@ll_same int,
@ls_sql varchar(200)
Begin
set @ll_sort =1
declare cur cursor for SELECT id,use_value FROM exam_use_sort order by isnull(use_value,0) desc
OPEN cur
fetch next from cur into @ls_id,@ldc_value
WHILE @@FETCH_STATUS = 0
BEGIN
update exam_use_sort set use_sort = @ll_sort where use_value = @ldc_value
select @ll_same = isnull(count(*),0) from exam_use_sort where use_value = @ldc_value
set @ll_sort = @ll_sort+1
if(@ll_same>=2)
begin
set @ll_same=@ll_same-1
declare @i int
set @i=0
while(@i<@ll_same)
begin
fetch next from cur
set @i=@i+1
end
end
fetch next from cur into @ls_id,@ldc_value
END
CLOSE cur;
DEALLOCATE cur;
End
-------------SELECT * FROM exam_use_sort ORDER BY use_value desc----------
GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO
---------代码结束----------------------
-------函数用到的表------------------
CREATE TABLE [exam_use_sort] (
[id] [varchar] (20) COLLATE Chinese_PRC_CI_AS NOT NULL ,
[use_value] [decimal](18, 2) NULL ,
[use_sort] [int] NULL
) ON [PRIMARY]
GO
