Форма 4 запрос SQL. На данной форме выводится параметрический запрос по полям “Название лекарства” и по ”Количеству проданных лекарств”.
Процедура Запроса SQL:
Процедура кнопки обновить список:
procedure TForm4.Button1Click(Sender: TObject);
Begin
Query1.Filtered:=false;
Query1.Active:=true;
end;
Процедура кнопки поиска:
procedure TForm4.Button3Click(Sender: TObject);
Begin
Query1.Filtered:=false;
Case Radiogroup1.itemindex of
0:pole:='Name_lek';
1:pole:='Kolvo_p_lek'
end;
Query1.Filtered:=true;
end;
procedure TForm4.Query1FilterRecord(DataSet: TDataSet;
var Accept: Boolean);
Begin
Accept:=Dataset[pole]=edit1.text;
end;
Форма 5 на ней показана информация о Программе.
ЗАКЛЮЧЕНИЕ
Данная программа пригодится небольшим фирмам занимающихся продажей и учетом лекарственных средств. Моя программа облегчит им работу, уменьшит работу с бумагами накладными и т.д.
После разработки своей программы я узнал более подробно о языке программирования Delphi и приложений к нему в частности BDE Administrator и Database Desktop. BDE Administrator нужен для установления псевдонима. При переносе базы данных на другой компьютер надо обязательно установить псевдоним т.е. каталог где она находится иначе при запуске базы данных выйдет сообщение об ошибке. Database Desktop нужна для создания и редактирования таблиц баз данных. Язык программирования Delphi является более простым для написания баз данных в нем есть все возможные компоненты упрощающие работу. На Delphi написано довольно большое число баз данных.
ЛИТЕРАТУРА
1. Delphi 3 и создание приложений баз данных Шумаков П.В. 704 с. иллюстрации есть.
2. Delphi 4 для профессионалов издание Питер М.Кенту 1088 с. иллюстрации есть.
