title: Remove some text from a column values
body: <p>I have a column in my table named title_id with some title ids. Each title id is stored like  </p>
  
  <pre><code>title_1 
  title_2
  title_3
  </code></pre>
  
  <p>where 1, 2, 3 are the actual ids of the titles. 
  I want to remove the " title_ " text from all the records. I have around 5000 records so I can't edit them manually.</p>
  
  <p>How can I do it with a query.</p>
  
  <p>Thanks in advance </p>
