Query to get total for missing Dates

Question

Hi All
Please help in writing this query.
I have a table with the below values
Tx_code -- TX_date --- Amount -- Accumlated_amt
101 -- 01-Jul-2011 -- 100 -- 100
102 -- 01-Jul-2011 -- 300 -- 300
103 -- 01-Jul-2011 -- 500 -- 500
101 -- 02-Jul-2011 -- 150 -- 250
103 -- 02-Jul-2011 -- 100 -- 600
101 -- 03-Jul-2011 -- 250 -- 500
103 -- 03-Jul-2011 -- 50 -- 650
I want the output as below
101 -- 01-Jul-2011 -- 100 -- 100
102 -- 01-Jul-2011 -- 300 -- 300
103 -- 01-Jul-2011 -- 500 -- 500
101 -- 02-Jul-2011 -- 150 -- 250
102 -- 02-Jul-2011 -- 0 -- 300
103 -- 02-Jul-2011 -- 100 -- 600
101 -- 03-Jul-2011 -- 250 -- 500
102 -- 03-Jul-2011 -- 0 -- 300
103 -- 03-Jul-2011 -- 50 -- 650
For Tx_code 102 is available in 01-Jul-2011 but not in 02-Jul-2011 and 03-Jul-2011
But i want this row in my output for all other dates.
Below are my database version info
Oracle Database 10g Release 10.2.0.1.0 - Production
PL/SQL Release 10.2.0.1.0 - Production
"CORE     10.2.0.1.0     Production"
TNS for 32-bit Windows: Version 10.2.0.1.0 - Production
NLSRTL Version 10.2.0.1.0 - Production
Thanks

There you are:SQL>WITH t AS
  2       (SELECT 101 AS tx_code, TO_DATE('01-Jul-2011', 'DD-MON-YYYY') AS tx_date, 100 AS amount,
  3               100 AS accumlated_amt
  4          FROM DUAL
  5        UNION ALL
  6        SELECT 102, TO_DATE('01-Jul-2011', 'DD-MON-YYYY'), 300, 300
  7          FROM DUAL
  8        UNION ALL
  9        SELECT 103, TO_DATE('01-Jul-2011', 'DD-MON-YYYY'), 500, 500
10          FROM DUAL
11        UNION ALL

23  SELECT   c.tx_code AS tx_code, c.tx_date AS tx_date, NVL(t.amount, 0) AS amount,
24           (SELECT MAX(t.accumlated_amt)KEEP (DENSE_RANK FIRST ORDER BY tx_date DESC)
25              FROM t
26             WHERE t.tx_code = c.tx_code AND t.tx_date <= c.tx_date) AS accumlated_amt
27      FROM (SELECT b.tx_code, tx_date
28              FROM (SELECT     a.min_date + LEVEL - 1 AS tx_date
