I keep the RI constraints in a separate file so I can re-create them when I need to... >>> "Hillensbeck, Preston" <PHillensbeck@sfbcic.com> 04/26/02 01:49PM >>> There isn't a DROP COLUMN function yet, but you can do this... SELECT ... -- select all columns but the one you want to remove INTO TABLE new_table FROM old_table; DROP TABLE old_table; ALTER TABLE new_table RENAME TO old_table; This is straight out of Bruce Momjian's book, so you can give him credit for this :) -----Original Message----- From: webmaster [mailto:webmaster@harbornet.com] Sent: Friday, April 26, 2002 7:51 AM To: pgsql-general@postgresql.org Subject: [GENERAL] delete column I know this is an easy question, but I can't find any info on how do this in the PostgreSQL book. How do you delete a column? I've been able to delete tables, db's, rows, etc. But can't figure out how to just delete a column. I'm running RedHat 7.2 and PostgreSQL 7.1 Thanks for any help. ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to majordomo@postgresql.org ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to majordomo@postgresql.org so that your message can get through to the mailing list cleanly
