Ken,
Just add the column with the correct name, and leave the other one alone.
You could create a check constraint to make sure it isn't used.
Better yet, create a real account and don't use SYS or SYSTEM, as that is never a good idea.
As you've already discovered, it really isn't all that convenient. ;)

Dave:
I am working on a database to do a DB conversion from IMS to 8.1.7. It is
only being used to load the data for the conversion process. No
application
software will be connected to it. So, for convenience I am doing
everything
as SYS. I am the only person using this DB on a dedicated W2000 server. I
accidentally added this column by the wrong name, so I want to delete the
column so I can add the column with the correct name. I would change the
name of the column but I have not found any syntax to do this.
Thanks,
Ken

Ken,
I rarely log into any of my databases as SYS - too much mischief can be made (and I'm just the fumble-fingered guy to make it). There are very few columns owned by SYS. Most of these are in tables designed to support the database. You need to be REAL careful. Could be that the table you're in is currently in use by virtue of the fact you're logged in as SYS.

8.1.7 logged in as SYS.
Will not let me drop a column because it belongs to SYS.
If I am logged in as SYS why can't I drop a column owned by SYS?
