Hi.

I'm new user of ODAC.
I have the latest stable version and using Delphi 2007.
I tried to use TOraLoader, but I can't even compile project and Delphi returns me an error.

My code is like this:

Code: Select all

unit aOraLoader;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, DB, DBAccess, Ora, DALoader, OraLoader, Buttons, BCBtns;

type
  TForm1 = class(TForm)
    OraSession1: TOraSession;
    OraLoader1: TOraLoader;
    ExtSpeedButton1: TExtSpeedButton;
    procedure ExtSpeedButton1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.ExtSpeedButton1Click(Sender: TObject);
begin
  OraLoader1.PutColumnData(0,1,'ABDUL');
  OraLoader1.PutColumnData(1,1,17);
  OraLoader1.Load;
end;

end.

When I compile, Delphi returns: [DCC Error] F2092 Program or unit 'ORALOADER' recursively uses itself

What am I doing wrong? In this example I try to insert one row in first field (type string) and second field (type number).
Thanks for help.

I created new project with same code and the code is fine I guess.
Now I got other error, after first statement is executed (OraLoader1.PutColumnData(0,1,'ABDUL');):

Access violation at address 62CDF5EC in module 'OraClient11.Dll'. Read of address 00000010.

Does anyone know why?

I have installed Oracle client(x86) 10g and 11g. Default is 11g on WinXP. I'm using DB 11gR2.

Hello,

You are using the TOraLoader component incorrectly. You should use the OnPutData event handler in the following way:

Code: Select all

procedure TForm1.ExtSpeedButton1Click(Sender: TObject); 
begin 
  OraLoader1.Load; 
end;

procedure TForm1.OraLoader1PutData(Sender: TOraLoader);
begin
  OraLoader1.PutColumnData(0,1,'ABDUL');
  OraLoader1.PutColumnData(1,1,17);
end;

You can also look at the example of the TOraLoader component using in ODACDemo. You can find ODACDemo in the %ODAC_Install_Directory%\Demos directory.
