[zhongzhen2014]

procedure TForm1.Button10Click(Sender: TObject);
var
StrSQL:string;
begin
ClientDataSet1.Close;
StrSQL:='select * from Input';
ClientDataSet1.CommandText:=StrSQL;
ClientDataSet1.Open;
ClientDataSet1.First;
while not ClientDataSet1.Eof do
begin
if ClientDataSet1.Fields[9].Value <> Null then ClientDataSet1.Fields[9].AsBoolean := True;
if ClientDataSet1.Fields[9].AsBoolean then
begin
ClientDataSet1.Edit;
ClientDataSet1.FieldByName('*****').AsString:=loginForm.edit2.Text;
ClientDataSet1.Post;
end;
ClientDataSet1.Next;
end;
ClientDataSet1.ApplyUpdates (-1);
