title: How to cast column within select query
body: <p>I have this query:</p>
  
  <pre><code>SELECT * FROM students
  WHERE name LIKE '%ka%' OR 
  tel LIKE '%12%' OR 
  address LIKE '%ka%'; 
  </code></pre>
  
  <p>but <code>tel</code> is an integer-type column and therefore I can't use the <code>%abc%</code> operator there (although I need to do it like that)</p>
  
  <p>How can I cast the <code>tel</code> column within this query?</p>
