Could someone explain what the following SQL query does?
<p>I have my suspicions but I want to independently verify, what does this query do? It's for a mybb forum database:</p>

<pre><code>SHOW COLUMNS FROM mybb_users LIKE 'unreadpms'
</code></pre>

<p>For clarification, I'm asking if this is a query to view all users' unread PMs (the suspicious part)? I know it seems 'Captain Obvious' but I'm attempting to "independently verify" "my suspicions".</p>
