Генерация sql сценария базы данных
На основе созданной физической модели данных PowerDesigner может автоматически сгенерироватьSQL сценарий базы данных
Перед генерацией SQL сценария создайте последовательность значений (SEQUENCE)и триггер для автоматического заполнения колонкиLIBNUMBER таблицыLIBRARY: Откройте свойства таблицыLIBRARY, щелкните на закладкеColumns, откройте свойства колонкиLIBNUMBERи создайте новую последовательностьSEQ_LIBNUMBERдля этой колонки. Выполните генерацию триггеров: Tools\RebuildObjects\RebuildTriggers
При генерации SQL сценария необходимо учитывать ограничения целевой СУБД, в частности в СУБДORACLE(8.1.6i) длина идентификаторов ограничена 30 символами.
Для генерации SQL сценария базы данных перейдите к физической модели и в выберите командуDatabase\GenerateDatabase…:
Проверьте параметры генерации SQL сценария (в частности убедитесь, что на закладкеDatabase включена генерация последовательностейCreate/Drop Sequences), укажите имя файла в который следует сохранитьSQL сценарий и нажмитеOk.
В результате будет создан следующий сценарий:
