That’s what I thought.

For me, these 2 « problems » are the same. The mapping could be
miswrote, which makes ODB produce an incorrect schema. Or, as using an
Entity as a Key isn’t supported yet, the compiler can also misinterpret
the pragmas.

Here is a workaround I’ve found 2 minutes ago (line 3):
# ifdef     ODB_COMPILER
#   pragma  db  value(OfferKey)
#   pragma  db  member(OfferKey::o)             table("invoice_carts")
 column("")

#   pragma  db  model                           version(1, 1, open)
#   pragma  db  object(Invoice)                 table("invoices")
#   pragma  db  member(Invoice::m_cart)         table("invoice_carts") \
                                                id_column("invoice_id") \
                                                key_column("offer_id") \
                                                key_type("UNSIGNED INT") \
                                                value_column("quantity")
[...]
# endif

With this, the columns in « *-odb.cxx » are correct (and taken from the
member(Invoice::m_cart) line)

Thank you.
