    <p>
      <indexterm audience="hidden">DROP VIEW statement</indexterm>
      Removes the specified view, which was originally created by the <codeph>CREATE VIEW</codeph> statement.
      Because a view is purely a logical construct (an alias for a query) with no physical data behind it,
      <codeph>DROP VIEW</codeph> only involves changes to metadata in the metastore database, not any data files in
      HDFS.
