关于SQLSERVER表中的TEXT字段问题？

Question

unit Unit1;interfaceuses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  StdCtrls, Db, DBCtrls, ADODB;type
  TForm1 = class(TForm)
    ADOTable1: TADOTable;
    DBMemo1: TDBMemo;
    Memo1: TMemo;
    DataSource1: TDataSource;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;var
  Form1: TForm1;implementation{$R *.DFM}procedure TForm1.Button1Click(Sender: TObject);
begin    ADOTable1.Edit;
    ADOTable1.FieldByName('hgfdgf').Text:=Memo1.text;
    if ADOTable1.State=dsedit then
    ADOTable1.Post;
end;end.以上代码想把MEMO中的内容加入到表中的hgfdgf字段，该字段为TEXT型。
为什么执行出错？

我自已搞好了。多谢unit Unit1;interfaceuses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  StdCtrls, Db, DBCtrls, ADODB;type
  TForm1 = class(TForm)
    ADOTable1: TADOTable;
    DBMemo1: TDBMemo;
    Memo1: TMemo;
    DataSource1: TDataSource;
    Button1: TButton;
    Memo2: TMemo;
    procedure Button1Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;var
  Form1: TForm1;implementation{$R *.DFM}procedure TForm1.Button1Click(Sender: TObject);
begin    ADOTable1.Edit;
    ADOTable1.FieldByName('hgfdgf').AsVariant:=Memo2.text+memo1.text;
    if ADOTable1.State=dsedit then
    ADOTable1.Post;
end;procedure TForm1.FormCreate(Sender: TObject);
begin
   memo2.text:=ADOTable1.FieldByName('hgfdgf').AsVariant;
end;end.
