title: Sum of two fields
body: <p>I have a mysql table with 2 fields: <code>numPears</code>(int) and <code>numApples</code>(int) and i'd like to have a <code>numFruit</code>(int) that automatically get these 2 values and sum them. Is that possible? </p>
  
  <p><strong>Example</strong></p>
  
  <p>So that if a query </p>
  
  <pre><code>INSERT INTO strange_table (fruitID, numPears, numApples) VALUES (1, 1, 5);
  </code></pre>
  
  <p>And then query</p>
  
  <pre><code>SELECT numFruit FROM strange_table WHERE fruitID = 1;
  </code></pre>
  
  <p>It returns me <code>6</code>.</p>
