title: Select min value AND timestamp of that min value from mysql query
body: <p>I am trying to query min value of column and its timestamp.</p>
  
  <p>Table "cars":</p>
  
  <pre><code>+----+------------+-------+
  | id | epoch_time | cars  |
  +----+------------+-------+
  |  1 |          1 |     5 |
  |  2 |          2 |    10 |
  |  3 |          3 |    15 |
  |  4 |          4 |    10 |
  |  5 |          5 |     3 |
  +----+------------+-------+
  </code></pre>
  
  <p>Expected result:</p>
  
  <pre><code>+----+------------+-------+
  | id | epoch_time | cars  |
  +----+------------+-------+
  |  5 |          5 |     3 |
  +----+------------+-------+
  
  </code></pre>
  
  <p>Tried so far: </p>
  
  <pre><code>SELECT min(cars), epoch_time FROM cars;
  </code></pre>
  
  <p>It picks up min value fine, but epoch_time is incorrect.</p>
  
  <p>I am expecting epoch_time to be corresponding to min(value) associated (by row).</p>
