title: Integration services string length need to be truncated
body: <p>I'm using integration services (SSIS), at the moment I'm getting the data from an excel source, the string <code>Description</code> comes with a length greater than 15 chars: the problem is that I can't find a way to truncate this data in order to save it in the database (the column database is varchar(15) and I can't change it).</p>
  
  <p>I was trying to use a derived column in order to truncate the data with no success.</p>
