Как упомянуто в ссылке ниже, я сначала запускаю поиск. Он дает мне идентификаторы электронной почты, а затем для каждого идентификатора электронной почты я вызываю запрос POST.
Перебор таблицы SQL Azure в фабрике данных Azure
Я упомянул @pipeline (). Parameters.tableList в пунктах настроек для каждого. И после каждого для меня я установил уведомление по электронной почте, чтобы проверить вывод @pipeline (). Parameters.leadList. Я все правильно понимаю, пока все хорошо.
Но когда я использую @item (), он возвращает мне ноль.
Я запутался, почему @item () дает мне ноль, хотя
@pipeline (). parameters.leadList в дочернем конвейере дает мне правильный
значение?
И я следовал этому подходу: https://docs.microsoft.com/en-us/azure/data-factory/tutorial-bulk-copy-portal
