title: get most updated parameter (SQL)
body: <p>consider the following table:</p>
  
  <pre><code>+-------+-----------+-----------+-----------+
  |   ID  |   param1  |   param2  |   param3  |
  +-------+-----------+-----------+-----------+
  |   1   |   12      |   21      |   1       |
  +-------+-----------+-----------+-----------+
  |   2   |   11      |   3       |   22      |
  +-------+-----------+-----------+-----------+
  |   3   |   55      |   17      |   22      |
  +-------+-----------+-----------+-----------+
  </code></pre>
  
  <p>I need an SQL query which gets the value of the most updated (= highest ID) value of a single parameter (for example, if I want the most updated param2 I want the query to return 17).
  I must say that I don't have any knowledge in SQL, I just encountered it at work and I need a solution for this specific problem. when I searched for solutions I only found solutions for getting the whole row, I only need a single parameter from it.
  thanks.</p>
