title: send email task on error in sql
body: <p>HI All,</p>
  
  <p>I have a simple lookup transformation which finds matched and unmatched records, it creates table for matched and unmatched records. Now I want to send an email when the package finds any unmatched records and package should stop right there.</p>
  
  <p>Thanks </p>
