Subject: Delete with join -- deleting related table entries?
Date: Wed, 08 Feb 2006 09:14:11 -0800
Message-ID: <43EA26E3.9040903@obviously.com> (raw)

When I delete a record from a certain table, I need to delete a
(possibly) attached note as well.  How can I do this with postgres?  The
tables are like this:

reservation
    reservation_id
    stuff...

isuse
    issue_id
    reservation_id
    stuff..

note
    issue_id
    text comments...

A select that pulls out what I want to delete is:

    SELECT reservation_id,issue_id,note_id,eg_note.comments FROM
eg_reservation
       LEFT JOIN eg_issue USING (reservation_id)
       LEFT JOIN eg_note USING (issue_id)
       WHERE reservation_id > condition;

Can anyone help me turn this into a DELETE statement?
