To find 2nd highest salary in employee table

Hi,
I want to know how to calculate the 2nd highest salaried employee details.
rownum "=" sign cannot be used i suppose and
with and without using orderby clause.
both the methods needed.
cheers,

With order by
select * from
   ( select q.*, rownum as rn from
      ( select * from emp order by sal desc ) q
where rn=2
/With analytics:
select empno , sal
from ( select empno , sal
              , dense_rank () over (order by sal desc) as sal_rank
       from emp )
where sal_rank = 2Notice that DENSE_RANK() might give us a different result compared to RANK() and both give us a different result from the first example.

Pls help - can't find contacts easily on N95 8GB

Hi there. Just got my new N95 8GB -2 & when i add a new contact i can find it by scrolling all the way down but not by one letter. eg I have entered a contact just as M but when i go contacts> M , i get a list of everything with M starting at A!! eg Alan M,Bob m & so on -How do i set up to get it (1st letter) as 1st choice as with all my other phones? Have tried First name or surname but makes no difference......... Can anyone help?

Not giving excuses for Nokia.
But the way the search function seems to work is that when you type M it brings up all the contacts that contain M in it, in alphabetical order.
But if you have many many names then as you type it starts filtering them.
This is how Video Center and Music Player works as well. So it's a bit of backwards logic you think but really I think there's a reason.
Say you have many contacts saved. Now you know that this person first or last name starts with ME, but you don't know if it's the last or first name or that ME may be part of the name but not at the beginning then as you type ME it will bring all the contacts that have ME either at the beginning the middle or wherever.
So there's some logic to it but maybe not a lot...
640K Should be enough for everybody

Pls help me to find admin tool for latest bi linux version

Hello,
Oracle Business Intelligence, v. 11.1.1.5.0
I installed the latest version of OBIEE of linux version 64 bit on the server.
Installation went fine.
Now the only problem is finding Admin tool.
Could u pls tell me where its sitting.
I know i Windows it Admintool.exe
Thanks

Hi user,
Firstly you wont have admin tool for linux environment....you need to install the client on windows local machine and access the BI server of linux by setting up a connection.
So you need to download 64-bit or 32-bit windows one to install http://www.oracle.com/technetwork/middleware/bi-enterprise-edition/downloads/biee-111150-393613.html
