 <h2><a name="add_key" id="add_key"></a>Adding Keys</h2>

 <p>Generally speaking, you'll want your table to have Keys. This is accomplished with <dfn>$this-&gt;dbforge-&gt;add_key('field')</dfn>. An optional second parameter set to TRUE will make it a primary key. Note that <dfn>add_key()</dfn> must be followed by a call to <dfn>create_table()</dfn>.</p>

+<p>Multiple column non-primary keys must be sent as an array.  Sample output below is for MySQL.</p>

 <p><code>$this-&gt;dbforge-&gt;add_key('blog_id', TRUE);<br />

-    // gives PRIMARY KEY (blog_id)<br />

+    // gives PRIMARY KEY `blog_id` (`blog_id`)<br />

     <br />

+    $this-&gt;dbforge-&gt;add_key('blog_id', TRUE);<br />

+    $this-&gt;dbforge-&gt;add_key('site_id', TRUE);<br />

+    // gives PRIMARY KEY `blog_id_site_id` (`blog_id`, `site_id`)<br />

+	<br />

     $this-&gt;dbforge-&gt;add_key('blog_name');<br />

-    // gives KEY (blog_name)</code></p>

+    // gives KEY `blog_name` (`blog_name`)<br />

+    <br />

+    $this-&gt;dbforge-&gt;add_key(array('blog_name', 'blog_label'));<br />

+    // gives KEY `blog_name_blog_label` (`blog_name`, `blog_label`)</code></p>

 <h2><a name="create_table" id="create_table"></a>Creating a table</h2>

 <p>After fields and keys have been declared, you can create a new table with</p>

 <p><code>$this-&gt;dbforge-&gt;create_table('table_name');<br />
