Another method is to create a new table with only the desired fields with the SELECT INTO query i.e. SELECT <desired query> INTO TABLE <new table> FROM <old table> then, after deleting the old table, you will need to rename the new, temporary table, to that of your old table. Your conditions will need to be reset with the new table, as it will only contain data. Hope that help ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Kevin Drewiske '01 CE MSOE Webmaster Team: http://www.msoe.edu/ KJDesign Website Development: http://www.drewiske.com/KJDesign/ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -----Original Message----- From: Patrick Welche [SMTP:prlw1@newn.cam.ac.uk] Sent: Monday, August 13, 2001 09:37 To: Fariba Noorbakhsh Cc: pgsql-general@postgresql.org Subject: Re: delete columns from table!

Then drop the table and reload from table.txt. YMMV..
