Hi list...
Please i have a problem with this...
I create the follow tables...
--------------------------------------------------------
CREATE TABLE empresa (
id_empresa integer NOT NULL primary key,
nombre varchar(45),
);
CREATE TABLE casino (
id_casino integer NOT NULL,
id_empresa integer REFERENCES empresa(id_empresa),
nombre varchar(45),
primary key(id_casino,id_empresa)
);
CREATE TABLE maq_casino (
id_empresa integer NOT NULL REFERENCES casino(id_empresa),
id_casino integer NOT NULL REFERENCES casino(id_casino),
ubicacion_sala varchar(45) default NULL,
primary key(id_empresa,id_casino,id_tipo_maquina,id_maq_casino)
);
--------------------------------------------------------
When i'm gonna to create the last table i got this error:
ERROR: no hay restriccion unique que coincida con las columnas dadas en la
tabla referida <<casino>>
That in english is like .. there is no a unique constraint with columns
referred in casino table.
