title: SQL: select where either column is matched
body: <p>I'll illustrate my problem:</p>
  
  <p>Look at the table with two columns: Col1 and Col2.</p>
  
  <pre><code>-----------------   
  | Col1  | Col2  |
  -----------------
  | 1a1   | 2b2   |
  -----------------
  | 11b   | 22a   |
  -----------------
  </code></pre>
  
  <p>I am trying to select values that contain an <strong><code>a</code></strong> in either column.</p>
  
  <p>The desired output would be:</p>
  
  <pre><code>------------
  | MyNewCol |
  ------------
  | 1a1      |
  ------------
  | 22a      |
  ------------ 
  </code></pre>
  
  <p>Thank you in advance for your time.</p>
