I create a table (addresses) & its "historification". When an address is modified, it's moved to the historification which is basically a copy on "update" or "delete". I seem to have a proble & I wanna find the RULE I created to alter them. What command should I issue for that. I seem to not be able to find any \d command for that ... Could some one hint me ? Tx, Thomas, =============================== -- This table is really useless as such -- ************************************* CREATE TABLE historification ( pkh SERIAL, -- This will be the moment the record is "archived" dateend TIMESTAMP DEFAULT CURRENT_TIMESTAMP); -- Here is a basic address table CREATE TABLE addresses ( pk SERIAL, street CHAR(50) NOT NULL, street2 CHAR(50), zip CHAR(10) NOT NULL, city CHAR(30) NOT NULL, -- I have a table countries where the countries -- iso-codes are stored Country CHAR(2) REFERENCES COUNTRIES, datemodified TIMESTAMP DEFAULT CURRENT_TIMESTAMP); -- Here is the PostgreSQL historification CREATE TABLE AddressHistorics () INHERITS (historification, addresses); CREATE RULE update_address AS ON UPDATE TO addresses DO INSERT INTO AddressHistorics (pk, street, street2, zip, city, country, datemodified) VALUES (old.pk, old.street, old.street2, old.zip, old.city, old.country, old.datemodified); CREATE RULE delete_address AS ON DELETE TO Addresses DO INSERT INTO AddressHistorics (pk, street, street2, zip, city, country, datemodified) VALUES (old.pk, old.street, old.street2, old.zip, old.city, old.country, old.datemodified); -- Thomas SMETS rue J.
