Я собираю таблицу, содержащую наши данные календаря и связанные с ней метрики.Я должен отметить, что в настоящее время у нас есть очень индивидуальный розничный календарь, основанный на 4-5-4 розничных версиях.Так что, если что-то выглядит немного странно, вот почему (например, 31.03.19 классифицируется как часть 19 апреля)
Вот пример
| day | day_of_wk | day_of_mnth | day_of_qtr | day_of_yr | wk | wk_of_mnth | wk_of_yr | mnth | mnth_of_yr | qtr_of_yr | _yr |

Я пытаюсьсоздать таблицу, которая идентифицирует
Какова дата совпадения для этого дня в прошлом году с использованием поля day_of_yr (Пример: в то время как сегодня - 4/11/19, соответствующий день в прошлом годуна самом деле 4/12/18, потому что day_of_yr это 103)?То же самое для вчерашнего дня
Какие дни соответствуют текущей неделе и этой неделе в прошлом году
Какие дни соответствуют текущему месяцу и этому месяцу в прошломгод
Какие дни соответствуют текущему кварталу за этот квартал прошлого года
Окончательный результат будет выглядеть как
| day | day_of_wk | day_of_mnth | day_of_qtr | day_of_yr | wk | wk_of_mnth | wk_of_yr | mnth | mnth_of_yr | qtr_of_yr | _yr | today | today_last_yr | yesterday | yesterday_last_yr | this_wk | this_wk_last_yr | this_mnth | this_mnth_last_yr | this_qtr | this_qtr_last_yr |
