Enrico,
check out this :
procedure TForm1.PumpClick(Sender: TObject);
begin
Table1.Open;
Table1.First;
IB_DSQL1.SQL.Clear;
IB_DSQL1.SQL.Add('insert into T (FIRST_NAME,LAST_NAME) values (:FIRST_NAME,:LAST_NAME)');
IB_DSQL1.Prepare;
while not Table1.Eof do begin
Table1.Next;
IB_DSQL1.ParamByName('FIRST_NAME').AsString := Table1.FieldByName('LAST_NAME').AsString;
IB_DSQL1.ParamByName('LAST_NAME').AsString := Table1.FieldByName('LAST_NAME').AsString;
IB_DSQL1.ExecSQL;
end;
// no AutoCommit !!
IB_Transaction1.Commit;
end;
Bevor, consider to deactivate your Indexes on your destination table !
Do you have any triggers active on destination table ?
This should be speed up your import.
