A primary key is a field or set of fields with values that are unique throughout a table. Values of the key can be used to refer to entire records, because each record has a different value for the key. Each table can only have one primary key. Access can automatically create a primary key field for you when you create a table, or you can specify the fields that you want to use as the primary key. This article explains how and why to use primary keys.
To set a table’s primary key, open the table in Design view. Select the field (or fields) that you want to use, and then on the ribbon, click Primary Key.
