  ****************************************************************
  SQLCODE -811 can occur when using FETCH FIRST ROW ONLY
  in conjunction with optimization hints.
  Optimization hints cause the code for FETCH FIRST to be
  skipped inadvertently when the hint is used.  When
  FETCH FIRST is used, we could attempt to fetch more than one
  row.

Problem conclusion

• Code is changed to allow FETCH FIRST processing even when
  optimization hints are active.
