Oracle Pivot Queries

Hey there experts.

Say for example I have a query that returns a result set like:

Date          Job           Pay          Bonus        Tax
------------------------------------------------------------
07/2004    Manager    80000       5000        32000
07/2004    Clerk         20000        200          1000
08/2004    Clerk         25000        850          1300
08/2004    Cleaner     12000         0             500


What I would like to achieve is to perform a pivot on this result set so that the query returns the figures in the following way:


Job            Pay (July)       Bonus (July)       Tax (July)      Pay (August)       Bonus (August)       Tax (August)    
---------------------------------------------------------------------------------------------------------------------------------
Manager     80000              5000                    32000             0                         0                          0
Clerk          20000              200                       1000           25000                  850                      1300
Cleaner          0                    0                           0              12000                   0                          500


I hope that someone can help me out with this one!!

If you need some scripts to vreate and populate a test table then let me know!!!

Thanks

It will look something like this:

select job
,      sum(DECODE(to_char(date,'Month'),'July', pay)) as "sum_July_pay"
,      sum(DECODE(to_char(date,'Month'),'July', bonus)) as "sum_July_bonus"
,      sum(DECODE(to_char(date,'Month'),'July', tax)) as "sum_July_tax"
,      sum(DECODE(to_char(date,'Month'),'August', pay)) as "sum_August_pay"
,      sum(DECODE(to_char(date,'Month'),'August', bonus)) as "sum_August_bonus"
,      sum(DECODE(to_char(date,'Month'),'August', tax)) as "sum_August_tax"
from   mytable
group by job
order by job
