Hi folks,
I know I'm missing something blindingly obvious, can someone point it out to
me please.
create table locos ( -- Locos table - contains details of locos
lid int4 default nextval('loco_lid_seq'::text) unique not null,
lclass int4 references lclass(lcid), -- Loco Class
lbuilt date, -- Date off-shed
lcme int4 references cme(cmid), -- Chief Mechanical Engineer
lname character varying(30), -- Name of Loco
lcomments text -- free text comments
);
NOTICE: CREATE TABLE / UNIQUE will create implicit index 'locos_lid_key' for
table 'locos'
NOTICE: CREATE TABLE will create implicit trigger(s) for FOREIGN KEY check(s)
CREATE
create table lnumbers ( -- alternate loco numbers
lnid int4 not null references locos(lid),
lnumber character varying(10),
lncurrent bool,
primary key (lnid, lnumber)
);
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index 'lnumbers_pkey'
for table 'lnumbers'
NOTICE: CREATE TABLE will create implicit trigger(s) for FOREIGN KEY check(s)

create view loco_dets as select * from locos l left outer join (select * from lclass) lc on lc.lcid =
