I need to write a report from oracle sql that outputs the rows like columns so the analyst can compare the value
The output from oracle comes out to be
Year month   Product   Stats
200901         ABC          50.00
200902         ABC           40.00

it should look like
Product  Jan2009   STATS    Feb 2009  STATS  DElta (col3-5)

Are you looking for an arbitrary number of columns or just the two columns with the delta?

Assuming table name is samp

select yearmonth1, stats1, yearmonth2, stats2, stats1 - stats2 as delta from
 (select yearmonth as yearmonth1, stats as stats1 from samp where yearmonth = to_date('200901', 'yyyymm')) a,
 (select yearmonth as yearmonth2, stats as stats2 from samp where yearmonth = to_date('200902', 'yyyymm')) b
;

The sample data you gave contained only two rows. Perhaps you can explain your data in more detail?

I got the sql t work it was missing the where clause which I have to restrict,my only question is the table that I am refering to is already a view of 2 bigger tables of more than million rows, the query takes more time to execute just for a month as against directly querying the table for a month -

Yes, that is because views do not help speed up anything. they are simply stored queries. If you want to speed it up you'll need to create indexes on the columns that you are searching / limiting by.

Possibly the month column is not indexed.
