Returns a Boolean value that indicates whether an Index object represents a foreign key in a table (Microsoft Jet workspaces only).
The return value is TRUE if the Index object represents a foreign key.
Syntax
BOOLGetForeign(VOID);
Remarks
A foreign key consists of one or more fields in a foreign table that uniquely identify all records in a primary table.
The Microsoft Jet database engine creates an Index object for the foreign table and sets the Foreign property when you create a relationship that enforces referential integrity.
