Answer / jvdwhinfo

Hi There,

The DFD given in answer is absolutely correct in
informatica.

But coming to sql override stuff i agree with answer 4.
And i want to do little modification keeping performance in
view.
The modified query looks like this.

With salorder
As
(select * from emp)
select * from salorder where rownum <= 5
minus
select * from salorder where rownum <= 4;

Thanks,
James

Answer / chandrasekar

Hi Venkatesh,

The above SQL query is not working correctly..

I have one answer for the above problem. The query is, try
it in the SQL override.

select * from emp where sal=(select max(sal) from emp a
where (select count(sal) from emp b where b.sal >=a.sal)=5)

If it wrong means send the correct answers to me
