Hi folks. I'm looking at the possibility of implementing a photo gallery for my web site with a tree structure, something like:
create table gallery ( id serial, parent int4, name varchar(40), primary key (id)); create table photos ( pid serial, id int4 references gallery not null, added timestamp, pfile varchar(128) not null, pdesc varchar(40) not null, primary key (pid)); copy "gallery" from stdin; 1 0 Root 2 1 NYMR 3 1 Middleton 4 2 Steam Gala 5 2 Diesel Gala 6 2 From The Footplate 7 3 From The Footplate \. copy "photos" from stdin; 1 4 2004-11-10 10:10:00 80135-1.jpg 80135 light-engine 2 4 2004-11-10 12:12:00 6619-1.jpg 6619 on-shed 3 5 2004-10-01 10:00:00 D7628.jpg Sybilla 4 7 2004-01-01 09:12:12 mm-21.jpg No. 4 Mathew Murrey \. How would I go about creating a view to show a) the number of photos in a gallery and b) the timestamp of the most recent addition for a gallery, so that it interrogates all sub-galleries? For example NYMR should return 3, 2004-11-10 12:12, Middleton should return 1, 2004-01-01 09:12:12 and Root should return 4, 2004-11-10 12:12:00 -- Gary Stainburn This email does not contain private or confidential material as it may be snooped on by interested government parties for unknown and undisclosed purposes - Regulation of Investigatory Powers Act, 2000 ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
