Month count

Question

Oracle -9i Release 2
How do I write a sql query to get month-wise count for actual working day, i.e. exclude saturday and sundays from the month count, is there a way to do it, i have the following query that gives total count for each month, also it is not ordered by month.
SELECT TO_CHAR(xmonth.ddate,'MON'),COUNT(1)
FROM (SELECT TRUNC(SYSDATE,'mon') + ROWNUM - 1 ddate
FROM ALL_OBJECTS
WHERE TRUNC(SYSDATE,'mon') + ROWNUM - 1 <= LAST_DAY(TO_DATE('12/31/2005','mm/dd/yyyy')) ) xmonth
GROUP BY TO_CHAR(xmonth.ddate,'MON')

Answer 1

The following example should help.
  1  SELECT TO_CHAR(MYDATE,'MONTH YYYY') MONTH, COUNT(*) COUNT
  2  FROM(SELECT DATE '2004-01-01'+ ROWNUM -1 MYDATE
  3         FROM(SELECT 1 FROM DUAL
  4               GROUP BY CUBE(1,2,3,4,5,6,7,8,9)))
  5  WHERE MYDATE < DATE '2005-01-01'
  6  AND TO_CHAR(MYDATE,'DY') NOT IN ('SAT','SUN')
  7  GROUP BY TO_CHAR(MYDATE,'MONTH YYYY')
  8* ORDER BY TO_DATE(TO_CHAR(MYDATE,'MONTH YYYY'),'MONTH YYYY')
