body: <p>What is the best FUNCTION to search for a character inside a string sql?</p>
  
  <p>I've been trying to search if there exists a character inside a fixed string.</p>
  
  <p>For example I have: </p>
  
  <pre><code>1OF2. 040713 08:07 AM
  </code></pre>
  
  <p>And I want to know if there is a <code>'.'</code> inside the string.</p>
