Tabular Report Question

Question

Hi There,
I am in the middle of developing a tabular report my report format is the following and following parameters are passed. Its basically a LEDGER of a particular account therefore requrired to calculate the opening balance as well.
1. Account code
2. Start Date
3. End Date
Account : 3301001
Name : Bank of America
Start Date : 01-01-07 ..................End Date : 01-12-07 ..................
Acc_code.......Name ................Debit.........Credit...........Balance......................
...........Opening Balance of (Bank of America :)--------------> 800000 ..................
1.................Company 1.........5000.............................805000.......................
2.................Company 2.........2000.............................807000.......................
3.................Company 3.............................12000.......795000.......................
so based on that scenario I dont know how to do following things.
1. I need to pick current balance from main accounts table and put it on balance field at first line where it says "opening balance of (bank of america)
2. and add the balance into DEBIT or CREDIT which will act as a running balance.
3. User can leave the End date so how to teckle this...following is the query.
SELECT V_NO,VD_ENTRYDATE,V_VALUEDATE, ACC_CODE,ACCNAME,DEBIT,CREDIT FROM V_POOL
WHERE ACC_CODE <> &ACCODE AND COMPANYID = '01'
AND V_NO IN (SELECT DISTINCT V_NO FROM V_POOL WHERE ACC_CODE=&ACCODE AND COMPANYID=01 AND V_POSTED='T'
and TO_DATE(VD_ENTRYDATE,'DD-MM-YY') >= TO_DATE(&SDATE,'DD-MM-YY')
AND TO_DATE(VD_ENTRYDATE,'DD-MM-YY') <= TO_DATE(&EDATE,'DD-MM-YY')) order by v_no;

Hi,
try the following code for 2.
DECLARE
    vError VARCHAR2(32767);
BEGIN
    FOR i IN 1.. HTMLDB_APPLICATION.G_F03.COUNT
    LOOP
        IF HTMLDB_APPLICATION.G_F03(i) IS NULL
        THEN
            vError :=
                vError ||
                'Please enter a date on line ' || i ||
                '<br/>';
        END IF;
    END LOOP;
    FOR i IN 1.. HTMLDB_APPLICATION.G_F04.COUNT
    LOOP
        IF HTMLDB_APPLICATION.G_F04(i) <> ^[[:digit:]]{8}$
        THEN
            vError :=
                vError ||
                'Please enter an account number on line' || i ||
                '<br/>';
        END IF;
    END LOOP;
    FOR i IN 1.. HTMLDB_APPLICATION.G_F06.COUNT
    LOOP
        IF HTMLDB_APPLICATION.G_F06(i) IS NULL
        THEN
            vError :=
                vError ||
                'Please enter a quantity on line' || i ||
                '<br/>';
        END IF;
    END LOOP;
    RETURN vError;
END; BTW, are you sure that the regular expression "^[[:digit:]]{8}$" works that way in PL/SQL? Haven't used it very often yet, but I don't think you can specify it that way in PL/SQL.
