执行以下程序后，系统提示出错："Invalid use of Keyword Token 
ate>=?'
Query1.Sql.Clear;
Query1.Sql.Add('Select * from fp');
Query1.Sql.Add('Where Date>=ate1 And Date<=ate2');
Query1.Prepare;
Query1.Params[0].AsDate:=DateTimePicker1.Date;
Query1.Params[1].AsDate:=DateTimePicker2.Date;
Query1.Open;
不知是何道理？应如何改？请专家赐教！谢谢！！
我用的是Delphi4，数据库是DBF。
