Есть параметрический запрос.Я создаю параметры ,называю их даю значения ,подставляю в запрос все ок.Но как только p1.free
вылазит Acces violation.......

query2.Params.Clear;
P1 := TParam.Create(Query2.Params, ptInput);
Query2.Params[0].Name := "card_no";
Query2.ParamByname("card_no").Asfloat:=12......
