Note that the address book (table userdb) already contains a 
phone_night column. 

Of course after adding the columns, someone will come along who will need 
a company_3 and phone_emergency or phone_mobile, phone_beeper or 
whatever. 

But let's assume this will never happen.
The following way will probably work.

Just in case, you can save your old data with 

	mysqldump databasename >dumpfile

and later restore it with

	mysql databasename <dumpfile

After taking precautions to make sure you can restore the old situation,
edit file
	/var/lib/interchange/storename/dbconf/mysql/userdb.mysql 

Add the columns that you want to add.

After that use mysql to edit the database. You can add the two 
columns, e.g. with

	ALTER TABLE ADD COLUMN COMPANY_2 char(30);
(and similar for the phone number).

After that, quit mysql and restart the interchange server, it should recognize
the new table layout for the store.

Not really an interchange question, but an SQL question; probably you can
do what you want by clearing the address column, 

	update userdb set column='' where code=' (user ID)  '

If you want to drop the entire column from the table use 

	drop column column_name

If you need to, wrap this in a query tag.
