SQL益智题目，有点难度！！！！

SQL code

CREATE TABLE #t(    [Id] [int] IDENTITY(1,1) NOT NULL,    [Title] [nvarchar](50),    [CreationTime] [datetime] DEFAULT (getdate()),    [OrderIndex] [int],) go insert into #t(title,orderIndex) values('文章A',0)insert into #t(title,orderIndex) values('文章B',0)insert into #t(title,orderIndex) values('文章C',2)insert into #t(title,orderIndex) values('文章D',0)insert into #t(title,orderIndex) values('文章E',6)insert into #t(title,orderIndex) values('文章F',3)insert into #t(title,orderIndex) values('文章G',0)insert into #t(title,orderIndex) values('文章H',4)insert into #t(title,orderIndex) values('文章I',0)select * from #t

原表结果：
IdTitleCreationTimeOrderIndex
1文章A2010-03-19 14:32:29.6530
2文章B2010-03-19 14:32:29.6530
3文章C2010-03-19 14:32:29.6532
4文章D2010-03-19 14:32:29.6530
5文章E2010-03-19 14:32:29.6536
6文章F2010-03-19 14:32:29.6533
7文章G2010-03-19 14:32:29.6530
8文章H2010-03-19 14:32:29.6534
9文章I2010-03-19 14:32:29.6530

输出后结果：
IdTitleCreationTimeOrderIndex
1文章A2010-03-19 14:32:29.6530
3文章C2010-03-19 14:32:29.6532
6文章F2010-03-19 14:32:29.6533
8文章H2010-03-19 14:32:29.6534
2文章B2010-03-19 14:32:29.6530
5文章E2010-03-19 14:32:29.6536
4文章D2010-03-19 14:32:29.6530
7文章G2010-03-19 14:32:29.6530
9文章I2010-03-19 14:32:29.6530

PS: OrderIndex的相应值指定输出到某行，如OrderIndex=2 该记录对应输出到第2行，＝6，则记录输出到第6行，其它OrderIndex=0则默认按id降序。

[解决办法]
这个需求,不好做.得用循环或游标.帮顶.
[解决办法]
这个太益智了...

探讨

SQL code
--DROP TABLE #T
CREATE TABLE #t(
[Id] [int] IDENTITY(1,1) NOT NULL,
[Title] [nvarchar](50),
[CreationTime] [datetime] DEFAULT (getdate()),
[OrderIndex] [int],
)

go ……

[解决办法]
刚才的不对,SORRY.
这个运行过了的:
select rowId,Id,Title,CreationTime,OrderIndex
from
(
select rowId = id,rn = Row_Number() over(order by id) from #t where ID NOT IN (select orderindex from #t)
) A INNER JOIN
(
select *,rn = Row_Number() over(order by id) from #t where OrderIndex=0
) B ON A.rn=B.rn
UNION
select OrderIndex,* from #t where OrderIndex>0
order by 1
