      ** SAMPLE: How to delete table data
      **
      **         This program shows how to delete table data. It shows how
      **         to delete all the managers recorded in the 'staff' table
      **         of the sample database. ROLLBACK is issued at the end of
      **         program so that the sample database remains unchanged.
      **
      ** SQL STATEMENTS USED:
      **         BEGIN DECLARE SECTION
      **         END DECLARE SECTION
      **         EXECUTE IMMEDIATE
      **         CONNECT
      **         ROLLBACK
      **
      ** OUTPUT FILE: delet.out (available in the online documentation)
