Every table should have a primary key for easier accessing/identifying data in this table. There can only be one primary key per table and it is named always **PRIMARY**. In fact a primary key is just an :term:`unique key` with the name **PRIMARY**. If no primary key is defined MySQL will use first *unique key* as primary key if there is one. You can create the primary key when creating the table (in phpMyAdmin just check the primary key radio buttons for each field you wish to be part of the primary key). You can also add a primary key to an existing table with `ALTER` `TABLE` or `CREATE` `INDEX` (in phpMyAdmin you can just click on 'add index' on the table structure page below the listed fields).
