Hi All,
I have a simple table below and I want to be able to traverse it using SQL. Can somebody please advise me how I can do this in postgreSQL.
CREATE TABLE grouping
(
grouping_id int4 NOT NULL,
version int4,
parent_grouping_id int4,
topic_topic_id int4,
CONSTRAINT grouping_pkey PRIMARY KEY (grouping_id),
CONSTRAINT fk1e2e9d036852722d FOREIGN KEY (topic_topic_id)
REFERENCES topic (topic_id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION,
CONSTRAINT fk1e2e9d03a1bfbfe FOREIGN KEY (topic_topic_id)
REFERENCES topic (topic_id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION,
CONSTRAINT fk1e2e9d03cdaf7222 FOREIGN KEY (parent_grouping_id)
REFERENCES grouping (grouping_id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION
)
WITHOUT OIDS;
ALTER TABLE grouping OWNER TO napdba;
Thanks In Advance.
Gibson.
