EOF

property EOF: Boolean read;

Example​

procedure ProcessRows(const View: TdaSQLQueryDataView);
begin
  View.First;
  while not View.EOF do
  begin
    { process current row }
    View.Next;
  end;
end;

Usage​

EOF reports whether the client cursor is at or beyond its last visible record and is the normal forward-loop boundary.

  • Use First; while not EOF do ... Next for forward traversal.
  • Do not confuse EOF with Empty, which is implemented as pipeline EOF and is a cursor-state misnomer.
  • Avoid retaining field references/values without copying them before the next movement.

Additional Technical Info​

EOF is the forward cursor-boundary flag for a concrete DataView.

Source-backed behaviour​

The hidden base getter reads DataPipelines[0].EOF. TdaSQLQueryDataView and TdaCDSQueryDataView override it with FQuery.EOF, reading the underlying client dataset directly. EOF is true on an empty dataset and after movement beyond the last visible row. It is false while positioned on a valid last row.

Filters and master/detail ranges define the visible result. The read does not fetch or move by itself. SQL-view Next performs primary-key capture before movement, so a conventional loop has that additional side effect.
