What is the purpose of a primary key in a database? The primary key is the field-or combination of fields-that uniquely identify each record in a table. It is usually the primary key that is stored in other tables (in which â¦ case it is called a foreign key), to find the record in the specified table. For example, a client might be identified by a field ClientId, which uniquely identifies each client. In the client table, this field would be called the primary key; if used in other tables to refer to a client, it is called a foreign key. 40 people found this useful.
