If you are receiving ORA-1002 I suspect that you are using ODBC, and
if so, you need to update your ODBC driver.
The standard 8.1.7.4 ODBC driver does not allow you to control the
autocommit nature of ODBC.
Go to otn.oracle.com and click on Downloads.
Under the 'Drivers' section click on ODBC. There you will find
the 8.1.7.8.10 ODBC driver which will probably correct your ORA-1002
error.

I should also mention that along with the ORA-01722 error, I am also
receiving the ORA-01002: Fetch out of sequence error.
FYI, we are using version 8.1.7.4 and I am using TOAD on w2k pro.

I'm not sure why I'm leaning towards CAST...(I claim ignorance!)
In any case, I tried methods, both yours and Igor's, and received the
same error:
ORA-01722: invalid number
Somewhere in this table, there is a strange value. I was trying to make
life simpler without having to create multiple views to deal with these
data value issues (filter the view by some criteria).
So here's another question (just out of curiosity), how can I determine
which value is causing me problems?
Thanks for all your help so far! I appreciate the time.

Saira,
This worked:
CREATE OR REPLACE VIEW tomview
AS
SELECT
col1, col2,
cast(NVL(RTRIM(col1),0) AS NUMBER) col1_numb
FROM tomtest
Values for the TOMTEST table were (' ',1);
SELECT * FROM tomview
returns
values of (' ', 1, 0)
And I agree wih Igor - why are you using CAST rather than to_number?
