RE: [MS_AccessPros] Primary Key

 

There can only be one primary key per table. That primary key may be a complex key combining two or more fields. The combination that makes the primary key cannot be duplicated within the table. The individual fields that participate in the primary key may be duplicated within the table.

Is it possible when  defining multiple primary keys for a table, to specify that only the combined primary keys can not have duplicates , but the individual key can have duplicate entries?
