SQL code

Hi all,
I have the following data.

Table X

no name runtime

15 xyz 12:20:10
14 xya 12:20:10
13 xyb 12:20:10
12 xyc 12:20:10
11 xyd 12:20:10
10 xye 12:20:10
9 xyf 12:10:05
8 xyg 12:10:05
7 xyh 12:10:05
6 xyz 12:20:00
5 xya 12:20:00
4 xyb 12:20:00
3 xyc 12:20:00
2 xyd 12:20:00
2 xye 12:20:00


I need to build a view on this data and select only the latest rows that have run last at the same time runtime. I would NOT know the run when I run the statement. In the above, the result should have rows from no=15 thru no=10 (runtime 12:20:10).

I suppose I could do the following way:

select * from X
where runtime=(select runtime from X where rownum<2 order by runtime desc);

Any suggestion please.

Thanks,
Ramesh

select * from x where runtime=
(select max(runtime) from x);

Thanks Jurij
