ORA-24335 - cannot support more than 1000 columns - How to solve this?

Question

Hi,
I got error message 'ORA-24335 - cannot support more than 1000 columns ' when i try to insert x no of rows for a table with following code:
INSERT ALL
INTO tableA Values ('A', 'B', 'C', 1, 2, 3)
INTO tableA Values ('D', 'E', 'F', 4, 5, 6)
INTO tableA Values ('G', 'H', 'I', 7, 8, 9)
SELECT *
FROM DUAL
How to solve above?
What does it really mean? It's not as easy as if my table has 10 columns than I can't insert more than 100 rows (1000 columns divided with 10 columns = maximun 100 rows to insert), or?
Is there a better/more appropriate way to do insert many rows?
Should I do my inserts with an OracleTransaction (My application is developed with C# and asp.net), as ~follows
BEGIN
INSERT INTO tableA Values ('A', 'B', 'C', 1, 2, 3)
INSERT INTO tableA Values ('D', 'E', 'F', 4, 5, 6)
INSERT INTO tableA Values ('G', 'H', 'I', 7, 8, 9)
COMMIT
END
Thx in advance!

Hi,
So how did you solve the problem? Can you please give an example?
I have the same problem inserting over 1000 values into my Oracle DB. The table only has 51 columns but to speed up the insert command, I use bulk inserts via insert all command. I need to insert 100 rows at a time for a total of 5100 values.
Example:
SQLCmd = INSERT ALL INTO MYTABLE (VAL_ID,VAL_NAME,VAL_NUM,VAL_TIME,VAL_CMM,VAL_TIME1,VAL_TRIP,VAL_REMAINING,VAL_AGE,VAL_COUNT,VAL_RSTS,VAL_VOLT,VAL_RF,VAL_DC,VAL_HOPS,VAL_STATUS,VAL_ELAPSED,MODIFY_TIME) VALUES (?,?,?,TO_DATE(?,?),?,TO_DATE(?,?),?,?,?,?,?,?,?,?,?,?,?,SYSTIMESTAMP)
INTO MYTABLE (VAL_ID,VAL_NAME,VAL_NUM,VAL_TIME,VAL_CMM,VAL_TIME1,VAL_TRIP,VAL_REMAINING,VAL_AGE,VAL_COUNT,VAL_RSTS,VAL_VOLT,VAL_RF,VAL_DC,VAL_HOPS,VAL_STATUS,VAL_ELAPSED,MODIFY_TIME) VALUES (?,?,?,TO_DATE(?,?),?,TO_DATE(?,?),?,?,?,?,?,?,?,?,?,?,?,SYSTIMESTAMP)
INTO MYTABLE (VAL_ID,VAL_NAME,VAL_NUM,VAL_TIME,VAL_CMM,VAL_TIME1,VAL_TRIP,VAL_REMAINING,VAL_AGE,VAL_COUNT,VAL_RSTS,VAL_VOLT,VAL_RF,VAL_DC,VAL_HOPS,VAL_STATUS,VAL_ELAPSED,MODIFY_TIME) VALUES (?,?,?,TO_DATE(?,?),?,TO_DATE(?,?),?,?,?,?,?,?,?,?,?,?,?,SYSTIMESTAMP)
INTO MYTABLE (VAL_ID,VAL_NAME,VAL_NUM,VAL_TIME,VAL_CMM,VAL_TIME1,VAL_TRIP,VAL_REMAINING,VAL_AGE,VAL_COUNT,VAL_RSTS,VAL_VOLT,VAL_RF,VAL_DC,VAL_HOPS,VAL_STATUS,VAL_ELAPSED,MODIFY_TIME) VALUES (?,?,?,TO_DATE(?,?),?,TO_DATE(?,?),?,?,?,?,?,?,?,?,?,?,?,SYSTIMESTAMP)
SELECT 1 FROM DUAL
SQLVals = 1 22C38299 80700334 04-19-2012 13:55:33 mm-dd-yyyy hh24:mi:ss MCC93000 04/19/2012 13:55:42 mm-dd-yyyy hh24:mi:ss 12 4 0.792191 23 1 0.00 -113.50 13.48 9 1 9

Then I call: &DBInsert($sqlCmd, @sqlVals);
This is the error I get: ORA-24335: cannot support more than 1000 columns.
I need to insert about 879,500 rows (51 cols per row). The values I read from a text file in sets of about 48,000 and put them into a hash. I tried inserting one row at a time, but it takes too long, about 28 hrs! Then, I tried the bulk update with only 6 rows and the total time was about 25 minutes. Which is acceptable to us.
Thanks!
