PostgreSQL 9.2.3 I would like to have a generic strategy for updating a timestamp field on some tables whenever the table is updated. Is there a recommended strategy for doing this other than via the SQL UPDATE command? I think I read something about RULES. In the below example I have a table called test_table. I would ideally like to update the field called "updated_timestamp" whenever an update occurs by doing:
UPDATE test_table SET updated_timestamp=now() WHERE id=? While looking at the concept of RULES how do I say after an update happens update that particular record and not all of the records in test_table. Example table: CREATE TABLE test_table ( id integer NOT NULL, field1 character varying NOT NULL, field2 character varying NOT NULL, updated_timestamp timestamp with time zone DEFAULT now(), created_timestamp timestamp with time zone DEFAULT now() ); Thanks, Lance Campbell Software Architect Web Services at Public Affairs 217-333-0382 [University of Illinois at Urbana-Champaign logo]<http://illinois.edu/>
