Creating matrix in SQL

Question

I have an SQL script
select
     substr(e,5,2) || '-' || substr(e,1,4) period_entered,
     r region,
     count(q) Count_of_quotes
from
(     select     distinct
          sps.region_code r,
          to_char(oq.date_entered,'YYYYMM') e,
          oq.quotation_no q
     from
          ifsapp.order_quotation oq,
          ifsapp.sales_part_salesman sps
     where
          oq.salesman_code=sps.salesman_code(+)
     and
          oq.objstate in ('Released','Revised')
     and
          oq.company= upper('OIA')
     and
          oq.date_entered >=      ifsapp.km_util_api.conv_from_date_fmt('OIA','11/01/2006')
     and
          oq.date_entered <= ifsapp.km_util_api.conv_from_date_fmt('OIA','03/31/2007')+ ( 1 - 1/ ( 60*60*24 ) )
     and
          ('' is null or upper('')=oq.authorize_code)
     and
          ('' is null or sps.region_code like upper('%'))
group by
     e,
     rwhich generates output like this:
Period_Entered     Region     Count_Of_Quotes
11-2006          44
11-2006     US     712
11-2006     US01     119

03-2007     US11     138
03-2007     US12     69

      11-2006  12-2006  01-2007  02-2007  03-2007
           44       61       53       48       86

Hi!
You can check the following script --
select decode(period_entered,'11-2006',Q,0) "11-2006",
       decode(period_entered,'12-2006',Q,0) "12-2006",
        decode(period_entered,'01-2007',Q,0) "01-2007",
        decode(period_entered,'02-2007',Q,0) "02-2007",
        decode(period_entered,'03-2007',Q,0) "03-2007",
from (
select      substr(e,5,2) || '-' || substr(e,1,4) period_entered,     
        r region,     
          q
from (     
        select     distinct sps.region_code r,          
                  to_char(oq.date_entered,'YYYYMM') e,          
                    oq.quotation_no q      
          from     ifsapp.order_quotation oq,ifsapp.sales_part_salesman sps      
          where     oq.salesman_code=sps.salesman_code(+)      
          and          oq.objstate in ('Released','Revised')      
          and          oq.company= upper('OIA')      
          and          oq.date_entered >= ifsapp.km_util_api.conv_from_date_fmt('OIA','11/01/2006')      
          and          oq.date_entered <= ifsapp.km_util_api.conv_from_date_fmt('OIA','03/31/2007') + ( 1 - 1/ ( 60*60*24 ) )      
          and          ('' is null or upper('')=oq.authorize_code)     
          and          ('' is null or sps.region_code like upper('%'))
group by     e,     r
group by RegionN.B: Not Tested.
