关于Tquery的用法求助!

Question

Tquery可不可以用APPEND属性?我觉得可以用.代码如下:会报错.
query1.Close;
     query1.SQL.Clear;
     query1.SQL.Text:='delete show128';
     query1.ExecSQL;
     query1.Close;
     query1.SQL.Text:='select * from show128';
     query1.Open;
     try
            GetTable.Open;
       except
            Continue;
     end;
       //逐条写入数据库
      GetTable.First;
      while not GetTable.EOF do
      try
             query1.Append;//单步调试到这里报错
             for j:=0 to GetTable.FieldCount-1 do
                 if query1.FindField(GetTable.Fields[j].FieldName)<>nil then
                       query1.FindField(GetTable.Fields[j].FieldName).Value:=GetTable.Fields[j].Value;             Application.ProcessMessages;
             GetTable.Next;
        except
        //即使只有1条数据出错，也忽略整个文件
         GetTable.Close;
         Screen.Cursor:=crDefault;      end; //try

Answer 1

query1.SQL.Clear;
query1.SQL.Text:='select * from show128';

Answer 2

是啊，来晚了，requestlive就是read-only

Answer 3

query1.SQL.Clear;
     query1.SQL.Text:='delete show128';
     query1.ExecSQL;
     query1.Close;//query.sql.clear;这一句！
     query1.SQL.Text:='select * from show128';
     query1.Open;
