<dt id="term-primary-key">primary key<a class="headerlink" href="#term-primary-key" title="Permalink to this term">¶</a></dt><dd><p>A primary key is an index over one or more fields in a table with
unique values for every single row in this table. 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 <strong>PRIMARY</strong>.
In fact, a primary key is just an <a class="reference internal" href="#term-unique-key"><span class="xref std std-term">unique key</span></a> with the name
<strong>PRIMARY</strong>. If no primary key is defined MySQL will use first <em>unique
key</em> as primary key if there is one.</p>
<p>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).</p>
<p>You can also add a primary key to an existing table with <cite>ALTER</cite> <cite>TABLE</cite>
or <cite>CREATE</cite> <cite>INDEX</cite> (in phpMyAdmin you can just click on ‘add index’ on
the table structure page below the listed fields).</p>
