+<p><strong>row()</strong></p>
+<p>This method returns a single result row. If your query has more than

+<strong>object</strong>. Here&#8217;s a usage example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$query</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">query</span><span class="p">(</span><span class="s2">&quot;YOUR QUERY&quot;</span><span class="p">);</span>

+</pre></div>
+</div>
+<p>If you want a specific row returned you can submit the row number as a

+</pre></div>
+</div>
+<p>You can also add a second String parameter, which is the name of a class
+to instantiate the row with:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$query</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">query</span><span class="p">(</span><span class="s2">&quot;SELECT * FROM users LIMIT 1;&quot;</span><span class="p">);</span>

+</div>
+<p><strong>row_array()</strong></p>
+<p>Identical to the above <tt class="docutils literal"><span class="pre">row()</span></tt> method, except it returns an array.

+<span class="p">}</span>
+</pre></div>
+</div>
+<p>If you want a specific row returned you can submit the row number as a
+digit in the first parameter:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$row</span> <span class="o">=</span> <span class="nv">$query</span><span class="o">-&gt;</span><span class="na">row_array</span><span class="p">(</span><span class="mi">5</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>In addition, you can walk forward/backwards/first/last through your
+results using these variations:</p>
+<blockquote>
+<div><div class="line-block">
+<div class="line"><strong>$row = $query-&gt;first_row()</strong></div>

+<div class="line"><strong>$row = $query-&gt;previous_row()</strong></div>
+</div>
+</div></blockquote>
+<p>By default they return an object unless you put the word &#8220;array&#8221; in the
+parameter:</p>
+<blockquote>
+<div><div class="line-block">
+<div class="line"><strong>$row = $query-&gt;first_row(&#8216;array&#8217;)</strong></div>
+<div class="line"><strong>$row = $query-&gt;last_row(&#8216;array&#8217;)</strong></div>

+<div class="line"><strong>$row = $query-&gt;previous_row(&#8216;array&#8217;)</strong></div>
+</div>
+</div></blockquote>
+<div class="admonition note">

+</div>
+<p><strong>unbuffered_row()</strong></p>
+<p>This method returns a single result row without prefetching the whole

+<p><strong>num_rows()</strong></p>
+<p>The number of rows returned by the query. Note: In this example, $query

+<p><strong>free_result()</strong></p>
+<p>It frees the memory associated with the result and deletes the result

+result has been generated in order to cut down on memory consumption.</p>
