Needs another simple fix ! ( Sorry guys i was stuck w/something else! )

Question

Hi Guys,
What i m trying to do here is to sum all the transactions of current month from one table and get the balance of highest date of previous month from other table for a specific agent. I only want one single value. I wrote something (below) but it doesn't work. Please help me out; thnx
Select (Sum(a.Dollar)+(c.Balance)) Outstanding
From Sajjad.Agent_Trans a, Sajjad.Agent b, Sajjad.Agent_Payments c
Where a.Id = b.Id
And b.Source = c.Source
And b.Source = 'IQ'
And c.Pdate = (Select Max(Pdate)
From Sajjad.Agent_Payments
Where Source = 'IQ'
And Pdate Between Last_Day(Add_Months(Sysdate,-2)) + 1
And Last_Day(Add_Months(Sysdate,-1))
Group By c.Balance

sorry Guys i was stuck with somethng else and i thought that i have given enough intro to my problem. Anyways it was given me NO ROWS SELECTED msg. then i noticed that if i wrote pdate as To_Char(Pdate,'dd/mm/rr') = ... in all my query only than it gives result. But why i have to write like this ? As a side note i m taking input through this select statement (select sysdata into pdate from dual;) in my forms.

Look at the constraints on your subquery:
SELECT   (SUM (a.dollar) + (c.balance)) outstanding
    FROM sajjad.agent_trans a, sajjad.AGENT b, sajjad.agent_payments c
   WHERE a.ID = b.ID
     AND b.SOURCE = c.SOURCE
     AND b.SOURCE = 'IQ'
     AND c.pdate =
           (SELECT MAX (pdate)
              FROM sajjad.agent_payments
             WHERE SOURCE = 'IQ'
               AND pdate BETWEEN LAST_DAY (ADD_MONTHS (SYSDATE, -2)) + 1
                             AND LAST_DAY (ADD_MONTHS (SYSDATE, -1)))
GROUP BY c.balance;Examine the values you're looking between:
SQL> SELECT to_char(LAST_DAY (ADD_MONTHS (SYSDATE, -2)) + 1, 'yyyy-mm-dd hh24:mi:ss') AS d1,
  2         to_char(LAST_DAY (ADD_MONTHS (SYSDATE, -1)), 'yyyy-mm-dd hh24:mi:ss') AS d2
  3    FROM dual;
D1                  D2
2005-08-01 09:42:06 2005-08-31 09:42:06When you perform your to_char() conversion you're throwing away the hours/minutes/seconds components of the date. This may be what you're trying to do.
SELECT   (SUM (a.dollar) + (c.balance)) outstanding
    FROM sajjad.agent_trans a, sajjad.AGENT b, sajjad.agent_payments c
   WHERE a.ID = b.ID
     AND b.SOURCE = c.SOURCE
     AND b.SOURCE = 'IQ'
     AND c.pdate =
           (SELECT MAX (pdate)
              FROM sajjad.agent_payments
             WHERE SOURCE = 'IQ'
               AND pdate >= LAST_DAY (ADD_MONTHS (TRUNC(SYSDATE), -2)) + 1
               AND pdate < LAST_DAY (ADD_MONTHS (TRUNC(SYSDATE), -1)) + 1
GROUP BY c.balance;Oh, and it took me a bit to realized that you'd updated your initial post instead of adding a new one. I suspect that many folk look only at the newest posts instead of scrolling though all of the existing ones looking for changes that may have been made to them.
