ALTER TABLE INVOICING ADD COLUMN USERINT INT You could query the system tables, however it's probably just as easy to just execute your Alter statement above - if the column already exists, the statement will simply return you an exception, it won't cause any problem in the database. -- Wayne Niddery - Logic Fundamentals, Inc.
