Witam,
Robię coś takiego (w skrócie):
baza.toFile.FieldDefs.Clear;
AnyField := TIBStringField.Create(baza.toFile);
AnyField.FieldName := 'ANYTXT';
AnyField.Calculated := True;
AnyFieldield.DataSet := baza.toFile;
myFieldsList := AnyField.FieldName;
if baza.toFile.Active = TRUE then
baza.toFile.Active := FALSE;
with baza.toFile do
begin
SQL.Clear;
SQL.Add(' SELECT ');
SQL.Add(myFieldsList);
SQL.Add(' FROM ANYTABLE ');
Prepare;
Open;
end;
OutputFile := TIBOutputDelimitedFile.Create;
try
OutputFile.ColDelimiter := ',';
OutputFile.OutputTitles := TRUE;
OutputFile.FileName := 'D:\temp\tmp.csv';
baza.toFile.State
baza.toFile.BatchOutput(OutputFile);
finally
OutputFile.Destroy;
end;
toFile to TIBQuery ze zdefiniowanym zdarzeniem OnCalcFields. Podłączyłem na próbe TDBGrid przez DataSource i rzeczywiście dane textowe z selecta zmienił w DBGridzie. Natomiast w pliku nie mam wartości wyliczonej tylko to co jest faktycznie w tabeli.
procedure TDataModule.toFileCalcFields(DataSet: TDataSet);
begin
DataSet.FieldByName('ANYTXT').AsString := 'asdfg'; // example
end;
Jak zmusić OutputFile by używał metody onCalcFields obiektu(toFile) ?
Ver IBX 5.06
