Is typing date as string faster than using CURDATE()
<p>I'm writing a mysql query that finds all the records created in the last 90 days.  Does it make any difference in terms of speed to use:</p>

<pre><code>SELECT user_id
FROM users 
WHERE created_at &gt; '2016-06-16'
</code></pre>

<p>compared to:</p>

<pre><code>SELECT user_id
FROM users
WHERE created_at &gt; date_sub(curdate(), interval 90 day)
</code></pre>

<p>Is there another way that would be even faster?</p>
