Hi ...
I would be very happy if someone could please give me a hint on this subject, as PosgreSQL confuses me on this matter.
I have been trying to make a simple rule upon a insert statement to a table that refers to a sequence, but I keep getting this strange error every time i use this rule, saying :
ERROR: entity_seq.currval is not yet defined in this session
The idea is that I have two tables I like to bind on a insert to one of them, like this :
CREATE SEQUENCE entity_seq;
CREATE TABLE A (
id INTEGER DEFAULT nextval( 'entity_seq' ),
name TEXT
);
CREATE TABLE B (
name TEXT,
a_ref INTEGER NOT NULL -- REFERENCES A( id )
);
CREATE RULE insert_on_a
AS ON INSERT
TO A (
INSERT INTO B name, a_ref VALUES( name, currval( 'entity_seq' ));
);
Is this all wrong, or is the another way to get the new 'id' value from the A table ?
Im looking forward to be enlightened :-)
