The 'name' is the constraint-name specified in the FOREIGN KEY clause or, if a constraint-name was not specified, the first column-name specified in the clause.

Programmer response: The table definition must be modified to conform to the system-imposed limit of the sum of the length attributes of the columns identified in the PRIMARY KEY clause.
