title: Data Factory expression substring? Is there a function similar like right?
body: <p>Please help,</p>
  <p>How could I extract <strong>2019-04-02</strong> out of the following string with Azure data flow expression?</p>
  <p>ABC_DATASET-2019-04-02T02:10:03.5249248Z.parquet</p>
  <p>The first part of the string received as a ChildItem from a GetMetaData activity is dynamically. So in this case it is ABC_DATASET that is dynamic.</p>
  <p>Kind regards,</p>
  <p>D</p>
