[ADMIN] INT array field referencing same table

[Gareth Kirwan]

Title: Gareth Stationery

I just wanted to check that this is the right syntax for a table. CREATE TABLE articles (         id              INT PRIMARY KEY DEFAULT nextval('articles_seq'),         category        INT,         type            INT,         title           VARCHAR(50),         description     TEXT,         link            INT,         date    timestamp,         related[]       INT,         CONSTRAINT articles_categories_const FOREIGN KEY (category) REFERENCES a_categories (id) ON DELETE CASCADE,         CONSTRAINT articles_types_const FOREIGN KEY (type) REFERENCES a_types (id) ON DELETE CASCADE,         CONSTRAINT articles_links_const FOREIGN KEY (link) REFERENCES a_links (id) ON DELETE CASCADE,         CONSTRAINT articles_related_const FOREIGN KEY (related) REFERENCES articles (id)         ); The bit that I'm curious about is the related field. Can I do it like this / Should I do it like this. The array of integers should reference the id of the same table.   If anyone has any more general comments about the design, They'd be welcome too :-)   Should I index the date field if i expect it to be searched upon regularly ???   Thanks Regards   Gareth Kirwan Programming & Development, Thermeon Europe Ltd, [EMAIL PROTECTED] Tel: +44 (0) 1293 864 303 Thermeon Europe e-Card: gbjk
