Havingaprimarykeyconsistingofmorethanonefielditisnotpossibletodefinea

Having a primary key consisting of more than one field it
is not possible to define a relation to another table
properly.



e.g.:
Firm : int
Product: int

Both together define the primary key because the
product ID is only unique for each firm.
