Запрос SQL Server 2008 для запуска за последние 8 недель

Question

У меня есть база данных для заказов. Каждый заказ содержит введенную дату.

Я написал запрос, который возвращает заказы между датами x и y .... и он работает.

Но теперь мне нужно написать запрос для каждой недели за последние 8 недель.

Так что сначала следует запросить между воскресенью и субботой этой недели. Должна быть в состоянии определить, какая дата в воскресенье на этой неделе.

Следующий запрос должен запрашивать предыдущую неделю с воскресенья по субботу.

Затем предыдущий.

И так далее ........

Затем я планирую присоединиться все вместе в конце.

Любые идеи?

Я должен был быть более понятным, вот запрос, который я использую. Мне нужно запустить это 8 раз .... Один на текущую неделю в воскресенье, чтобы сидеть .. затем предыдущий и так далее.

ВЫБОР [ДатаРазмещения], COUNT (*) AS OrderTotal из [Заказы] ГДЕ ORDER_DATE между AND'2013 '2013/06/05'/06/11' группа по OrderComp

Answer 1

не версию, которую я использую лично, но должен быть прекрасным типичным сценарием создания таблицы даты. Нашел его, как через 2 секунды после создания таблицы даты. Создать один Присоединиться к нему по неделям.

Answer 2

Прежде всего, вам необходимо определить воскресенье текущей недели. Для этого вам понадобится следующий код

SELECT DATEADD(DAY, 1-DATEPART(WEEKDAY, GETDATE()), GETDATE()) 

Теперь в запросе, чтобы это виртуальная таблица в предложении FROM

FROM ...,(SELECT DATEADD(DAY, 1-DATEPART(WEEKDAY, GETDATE()), GETDATE()) AS THIS_SUNDAY) SQ1 

Затем в пункте WHERE можно применять условия, как followng который будет дайте вам заказы на предыдущую неделю.

ORDER DATE >= DATEADD(DAY,-7,SQ1.THIS_SUNDAY) AND ORDER DATE < SQ1.THIS_SUNDAY
