WHERE子句中的日期範圍從90天前到今天的日期

我寫了以下查詢，但是在WHERE子句中，我已經使用了日期範圍的特定日期。我希望日期範圍能夠自動計算 - 也就是說，截至今天的日期爲90天。我該怎麼做？WHERE子句中的日期範圍從90天前到今天的日期

SELECT Orders.Day,

你真的不把你的SQL查詢保存在這麼混亂嗎？ –

這不是今天的90天 - 這是從過去3個月到過去2天的121天。你今天想要一個90天的窗口，或者你現在擁有的東西嗎？如果是後者，實際的規則是什麼？ –

我想要一個90天的日期範圍。我剛剛在上面的查詢中顯示了120天的示例。 – user818671

如果它是微軟SQL 2000和最多（05，08，10）。然後只需使用：其中YourDate> =（GETDATE（） - 90）

select * from mytable where mydate > date_sub(now(), interval 90 day)

如果你想，直到「當月結束」，這是「當前的前3個月的月初」一切從你現在確實有，你可以使用DATEDIFF和DATEADD在一起：

WHERE 
    Orders.OrderDate >= DATEADD(month,DATEDIFF(month,20010101,CURRENT_TIMESTAMP),'20001001') and 
    Orders.OrderDate < DATEADD(month,DATEDIFF(month,20010101,CURRENT_TIMESTAMP),'20010201')

雖然我不知道這是什麼意思爲OrderDate是在未來。

日期文字是經過精心挑選的，它們之間有我們正在尋找的關係 - 例如， 20001001是20010101之前3個月的開始。20010201是20010101之前1個月的開始。
