当我将“connected”设置为“true”时会引发异常。

在使用表单设计器和可见的TSQLConnection组件时,我也会收到此消息。

有什么想法吗?

function TDBExpressConnector.GetConnection(username, password, servername: string) : TSQLConnection;
begin
  //take a username, password, and server
  //return a connected TSQLConnection
  try
    FSqlDB := TSQLConnection.Create(nil);
    with FSqlDB do begin
      Connected := False;
      DriverName := 'Oracle';
      GetDriverFunc := 'getSQLDriverORACLE';
      KeepConnection := True;
      LibraryName := 'dbxora30.dll';
      ConnectionName := 'OracleConnection';;

      Params.Clear;
      Params.Add('DriverName=Oracle');
      Params.Add('DataBase=' + servername);
      Params.Add('User_Name=' + username);
      Params.Add('Password=' + password);
      Params.Add('RowsetSize=20');
      Params.Add('BlobSize=-1');
      Params.Add('ErrorResourceFile=');
      Params.Add('LocaleCode=0000');
      Params.Add('Oracle TransIsolation=ReadCommited');
      Params.Add('OS Authentication=False');
      Params.Add('Multiple Transaction=False');
      Params.Add('Trim Char=False');
      Params.Add('Decimal Separator=.');

      LoginPrompt := False;
      Connected := True;
    end;

    Result := FSqlDB;
  except on e:Exception do
    raise;
  end;  //try-except
end;
