SQL Remove all rows where one value repeats
<p>Let's assume that I have table with one column like this</p>

<pre><code>1
1
1
2
3
4
5
5
</code></pre>

<p>I need to do something to make it look like this:</p>

<pre><code>2
3
4
</code></pre>

<p>I can't use DISTINCT, because it will keep at least one of "1" and one of "5". So, I just want to delete everything if it has same value for that column anywhere in table.</p>
