Setting a Primary Key Using the Table Wizard
When you create a table with the Table Wizard, you can choose either to set a primary key yourself or to have the wizard do it for you. If you set the primary key, a dialog box appears that allows you to select the primary key and define its data type. Access can generate primary key values automatically, or you can enter a unique value for each new record when you enter data.
