Summing columns to give a grand total

Question

Hi,
I'm sure this is simple using one of the GROUP BY extensions, but I'm having a particularly dumb day
I have the following SQL
  SELECT EGROUP.EDESC,
         SUM(DECODE(PERS.AGERANGE,'UNDER 16',1,0)) AS "UNDER 16",
         SUM(DECODE(PERS.AGERANGE,'16 - 25',1,0)) AS "16 - 25",
         SUM(DECODE(PERS.AGERANGE,'26 - 35',1,0)) AS "26 - 35",
         SUM(DECODE(PERS.AGERANGE,'36 - 45',1,0)) AS "36 - 45",
         SUM(DECODE(PERS.AGERANGE,'46 - 59',1,0)) AS "46 - 59",
         SUM(DECODE(PERS.AGERANGE,'60 +',1,0)) AS "60 +",
         SUM(DECODE(PERS.AGERANGE,'UNKNOWN',1,0)) AS "UNKNOWN",
         COUNT(PERS.PIN) AS "Total"
    FROM (SELECT 1 ORD, 'WBRI' ECODE, 'White British' EDESC FROM DUAL UNION ALL
          SELECT 2, 'WENG', 'White English' FROM DUAL UNION ALL
          SELECT 3, 'WSCO', 'White Scottish' FROM DUAL UNION ALL
          SELECT 4, 'WWEL', 'White Welsh' FROM DUAL UNION ALL
          SELECT 5, 'WIRI', 'White Irish' FROM DUAL UNION ALL
          SELECT 6, 'WOTH', 'White Other' FROM DUAL
         ) EGROUP,
         (SELECT 1234 PIN, 'WBRI' PCODE, 'UNDER 16' AGERANGE FROM DUAL UNION ALL
          SELECT 1235, 'WENG', '16 - 25' FROM DUAL UNION ALL
          SELECT 1236, 'WENG', '16 - 25' FROM DUAL
         ) PERS
   WHERE EGROUP.ECODE = PERS.PCODE(+)  
GROUP BY EGROUP.EDESC, EGROUP.ORD
ORDER BY EGROUP.ORD ASC  which produces
White British  1 0 0 0 0 0 0 1
White English  0 2 0 0 0 0 0 2
White Scottish 0 0 0 0 0 0 0 0
White Welsh    0 0 0 0 0 0 0 0
White Irish    0 0 0 0 0 0 0 0
White Other    0 0 0 0 0 0 0 0what I'd like is for a 'totals row' to also be output
White British  1 0 0 0 0 0 0 1
White English  0 2 0 0 0 0 0 2
White Scottish 0 0 0 0 0 0 0 0
White Welsh    0 0 0 0 0 0 0 0
White Irish    0 0 0 0 0 0 0 0
White Other    0 0 0 0 0 0 0 0
Total          1 2 0 0 0 0 0 3I really need to read the Data Warehousing manual, to try and understand how CUBE, ROLLUP and grouping sets work.
Thanks
Dave
