Обсуждение: Probable error on docs
Hi Folks,
At programmer\rules1139.htm, (Rules on INSERT, UPDATE and DELETE),
there are the following statments:
CREATE TABLE shoelace_log (
sl_name char(10), -- shoelace changed
sl_avail integer, -- new available value
log_who name, -- who did it
log_when datetime -- when
);
CREATE RULE log_shoelace AS ON UPDATE TO shoelace_data
WHERE NEW.sl_avail != OLD.sl_avail
DO INSERT INTO shoelace_log VALUES (
NEW.sl_name,
NEW.sl_avail,
getpgusername(),
'now'::text
);
In the RULE statment (the second one) there is a reference to a
[shoelace_data] relation. Shouldn't it be the name of the table just
created, [shoelace_log] ?
In the RULE statment there is also a refernce to [shoelace_log].
I'm using the docs from the last snapshot. Files are dated 05/08/2000.
Best Regards,
Howe.
I think the docs are correct. showlace_log holds changes to shoelace_data. > Hi Folks, > > > At programmer\rules1139.htm, (Rules on INSERT, UPDATE and DELETE), > there are the following statments: > > CREATE TABLE shoelace_log ( > sl_name char(10), -- shoelace changed > sl_avail integer, -- new available value > log_who name, -- who did it > log_when datetime -- when > ); > > CREATE RULE log_shoelace AS ON UPDATE TO shoelace_data > WHERE NEW.sl_avail != OLD.sl_avail > DO INSERT INTO shoelace_log VALUES ( > NEW.sl_name, > NEW.sl_avail, > getpgusername(), > 'now'::text > ); > > In the RULE statment (the second one) there is a reference to a > [shoelace_data] relation.
