Hello all,
Encountered the problem with using RULEs. Cannot log
(e.g. write some info about insertions into sepearate table)
insertions properly. Detailed description (not long or sophisticated)
follows:
I do:
1) CREATE TABLE colors (id SERIAL, color TEXT);
2) Create table for log info:
CREATE TABLE colors_log (color_id INT4, color TEXT);
3) Create RULE that actually makes log:
CREATE RULE log_color
AS ON INSERT
TO colors
DO INSERT INTO colors_log VALUES (NEW.id, NEW.color);
4) Make some insertions:
INSERT INTO colors (color) VALUES ('red');
The same for 'green', 'blue'.
5) SELECT * FROM colors;
id|color
--+-----
2|red
4|green
6|blue
Here appears the first question:
why 'id' is 2, 4, 6, not 1, 2, 3?
7) SELECT * FROM colors_log;
color_id|color
--------+-----
1|red
3|green
5|blue
The problem is: the 'id's differ. E.g.,
In colors_log table the saved 'id' are wrong.
Thanks!
