short GetRelationCount( );
throw( CDaoException, CMemoryException );
Return Value
The number of relations defined between tables in the database.
Remarks
Call this member function to obtain the number of relations defined between tables in the database. GetRelationCount is useful if you need to loop through all defined relations in the database’s Relations collection. To obtain information about a given relation in the collection, see GetRelationInfo.
To illustrate the concept of a relation, consider a Suppliers table and a Products table, which might have a one-to-many relationship. In this relationship, one supplier can supply more than one product. Other relations are one-to-one and many-to-many.
