, когда я выполнил это, на первой скорости было хорошо, но сейчас это занимает много времени, а скорость очень низкая Я не знаю почему, но я думаю, что мне следует очистить кеш.
Я хочу сказать, занимает около 1 дня, но еще не финиширует на 20%.
на самом деле это около SELECT в TABLE в базе данных [spt] и INSERT в другой базе данных [AB_Warehouse], но оба они находятся на одном сервере.
Обратите внимание: один файл хранится в базе данных [spt] у нас есть такие данные
«aa + tt + bb + rr + yy», и я разделился с помощью функции StringSplitXML, и каждый из них вставил в [Workspaces_Tbl] Level1 ... 15
это мой запрос:
