title: Update SQL table with values to update and values to compare both in separate comma delimited strings
body: <p>I have a SQL table where I need to update <code>Date</code> field of multiple Users. The primary key (<code>userId</code>) field is int. Now I am sending the <code>Date</code> values in a comma separated string (like "10/06/2013,12/05/2013,16/07/2013") and corresponding <code>userId</code> values also in a comma separated string (like "1001,1002,1005").</p>
  
  <p>How can I update all relevant Users in my stored procedure? Or should I send the <code>userId</code>s and <code>Date</code>s in any other way?</p>
