Hi Friends.Help me.I got an error when creating a view

create table usuario(
id_usuario int primary key auto_increment,
nombre varchar(100) not null
)engine=innodb;

create table afiliacion(
id_afiliacion int primary key auto_increment,
id_padre int not null,
id_hijo int not null,
foreign key(id_padre) references usuario(id_usuario),
foreign key(id_hijo) references usuario(id_usuario)
)engine=innodb;

CREATE VIEW usuafi_view AS SELECT *
FROM afiliacion
INNER JOIN usuario AS p ON p.id_usuario=afiliacion.id_padre
INNER JOIN usuario AS h ON h.id_usuario=afiliacion.id_hijo;
