Here's a PL/pgsql implementation I wrote.....I'm sure critics will be able to improve upon it:
CREATE or REPLACE FUNCTION "common"."newid"() RETURNS "pg_catalog"."varchar" AS $BODY$ DECLARE v_seed_value varchar(32); BEGIN select md5( inet_client_addr()::varchar || timeofday() || inet_server_addr()::varchar || to_hex(inet_client_port()) ) into v_seed_value; return (substr(v_seed_value,1,8) || '-' || substr(v_seed_value,9,4) || '-' || substr(v_seed_value,13,4) || '-' || substr(v_seed_value,17,4) || '-' || substr(v_seed_value,21,12)); END; $BODY$ LANGUAGE 'plpgsql' VOLATILE SECURITY DEFINER; ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
