title: How to remove the first character if it is a specific character in SQL
body: <p>I currently have a table <code>Telephone</code> it has entries like the following:</p>
  
  <pre><code>9073456789101
  +773456789101
  0773456789101
  </code></pre>
  
  <p>What I want to do is remove only the 9 from the start of all the entries that have a 9 there but leave the others as they are.</p>
  
  <p>any help would be greatly appreciated. </p>
