Question

它有很多具有NULL值的行，我使用以下查询删除了它：

/* DELETE EVERY ROW EXCEPT THE ROW WE NEED */
DELETE FROM [Database].[dbo].[Table]
    WHERE
    ([Week Of*] IS NULL)

如何编写一个查询，该查询将从当前滚动周开始前12周并将[F4]值插入表格

Answer 1

SELECT f4
FROM yourtable
WHERE DATEADD(week, -12, [Week Of*]) >= 12

Answer 2

我最后使用了以下这些给了我最近12周的时间（我怎么用14来获得12周的时间。仍然试图找出原因：

SELECT CONVERT(VARCHAR(10),[Week Of*],110) AS [Date], [F18] AS [TOTALS] FROM [db].[DBO].[table] WHERE CONVERT(VARCHAR(10),[Week Of*],110) >= DATEADD(week, -14, GETDATE())

如何在SQL中选择前12周
