title: A regular expression to check if a column contains another column value
body: <p>I have a specific scenarios which is stated like below :
  Table <code>T1</code> contains <code>Name</code> and <code>status</code>. Table <code>T2</code> contains column <code>Name_status</code>. <code>status</code> will have values of <code>pass</code> and <code>fail</code>. <code>Name_status</code> should have values like <code>&lt;Name&gt;_&lt;status&gt;ed</code>. </p>
  
  <p>Can we think of a regular expression which would fetch all the values in <code>&lt;Name&gt;_&lt;status&gt;ed</code> format.</p>
  
  <p>Any help would be appreciated. Thanks</p>
