Question

What are the two ways of setting a field as a Primary Key field?​

Answer 1

Select the field or fields that you want to use as the primary key. To select one field, click the row selector for the field you want. To select more than one field to create a composite key, hold down CTRL and then click the row selector for each field. On the Design tab, in the Tools group, click Primary Key.
