I need to use 1 record in a file to create another record in the same file. The new record has the same column values except 1 or 2 columns. Is there a simple way to do this? I try to avoid reading every column to parse a INSERT string? Thanks.

The only solution that I can think of ( If I understand your question correctly ) is to use a DB specific SQL statement like: insert into table2 ( column1, column2,... ) select column1, column2,... from table1 where .... the above example works for Oracle, but may vary for other DB vendors. Jamie

Thanks. Looks like there is no trick doing this. I need copy to happen in the same file.

why not just change table2 to table1. It will insert into table1 based on a query on the same table( table1 ).

Thanks again. I tried and the same table copy works. But now I am duplicating record. How can I alter 1 of the columns before insert? I am using this sql string: insert into cust01 (select * from cust01 where custid=1002) What I want is to change custid to 1003 before insert the record into database.

Hi Bruce, You 'll need to get rid of the ugly "select *". It 'll have to be something like this . Let me also suggest that you 'd do yourself a favour reading up on SQL, if you plan to do this sort of thing more often. Good riding, Rudy.
