which transformation should we use to get the 5th rank
member from a table in informatica?can we achieve this in
sql?
Answers were Sorted based on User's Feedback
FOR THIS WE HAVE 2 USE TWO T/R ie FIRST WE HAVE 2 USE RANK T/R
AND THEN USE A FILTER T/R IN FILTER GIVE THE CONDITION AS
RANK=5 CONNECT TO TARGET
THE FLOW IS LIKE THIS
SRC --->SQ--->RANK--->FILTER--->TRG
WE CAN ALSO DO THIS IN SQL USE THE FOLLOWING QUERY
SELECT * FROM <TABLE_NAME> WHERE ROWNUM <= 5 MINUS SELECT *
FROM <TABLE_NAME> WHERE ROWNUM <=4;

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

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
