Hi there.. Is is it possible to describe multi-column foreign keys with SA metadata?
I.e. create table customers ( customer_id string, primary key (customer_id) ) create table users ( customer_id string, username string, primary key (customer_id, username), foreign key (customer_id) references customers (customer_id) ) create table preferences ( customer_id string, username string, preference_id string, preference_value string, primary key (customer_id, username, perference_id), foreign key (customer_id, username) references users (customer_id, username) ) This model is a made-up simplification of what I need to do.. but basically it's the last foreign key I can't figure out if I can describe with SA metadata. The only solution I see is to put a relation property on the "user" mapper that uses a custom join condition. However, this is standard SQL so shouldn't SA be able to handle this automatically if there is a ForeignKey specification on the table-object?
