RE: How to duplicate records
Just a thought on something I was reading with temp tables: 1. extract the records you want to change the date on from your existing table to a temp table. 2. update the date in the temp table 3. insert the new records back into the original table. This avoids the csv extract and changing then reinserting.

When extracting the records into the temporary table, just change SELECT Code, Model, Units, Year to SELECT Code, Model, Units, 2003 in your SQL. -- Keith C.

You can't do it with one SQL statement. MySQL has INSERT .. SELECT and REPLACe .. SELECT statements but you can't retrieve data from the same table into which you are inserting. What about inserting necessary data into temporary table and than upload them into your table? You can find info about INSERT .. SELECT and REPLACE ..
