Why must you use a primary key?

A primary key uniquely identifies a row in a table. A table without a key is not in normal form (i.e. considered a bad practice). Without a primary key, a database programmer risks inadvertently updating or deleting more records than they intended.All tables should have a primary key, although this key may be a composite of various fields.For example, if a developer uses "update contacts set firstname = 'John' where firstname='Jacob' and lastname = 'Smith'", they will likely update many records when they may have only intended to update a single record. By using a unique key, a developer can instead state "update contacts set firstname = 'John' where uid = 1234", and only a single record will be updated.Primary keys also increase access to specific records when the developer knows ahead of time what specific value they are looking for. For example, a developer might display a list of contacts matching a first name and last name, and when the user selects a specific record to view, retrieving by the primary key will be faster than querying by multiple indices (such as first name and last name).
