I had a request to refresh and old database where the user uses an app tied to this database.  I'd be getting the data from the same database structure except the one column has been added to all of the source tables making them one column different than the target database tables.  Of course when I try to do the import I get errors because of this difference.  Is there an attribute for either exp or expdp that I should explore to allow this data (excluding this added column) to me imported into these older database tables?  

Also this old database is on a stand-alone laptop and not accessible to the network where the source database is or I world have looked at other options like 'insert into old_table...'

I don't believe there is a way to export or import specific columns.

Can you not just add the new column to the target database?

If the app doesn't use it, then it really shouldn't matter unless the developer did some very bad things and use '*' like: select * from sometable;

You could always create a new table in the source database without the column, export that and remap_table on import.

Ok I thought I'd ask.  Yes creating a new table in the source database without the column might be the way to go.
