Question

在我的查询中，我试图获取昨天的日期和所选年份的完全相同的日期。所以今天是12/08/2010

我想要12/07/2010和12/07/2009

我忘了提到创建数据库的最后一个人将所有预订日期存储为intgers所以基本上

我的日期看起来像这样：（

所以这将取代我的上一个查询

Declare @YearToget Integer 
Set @yearToGet = 2008

SELECT TOP (100) PERCENT DIVISION, SDESCR, 
      DYYYY, SUM(APRICE) AS Sales, SUM(PARTY) AS PAX, 
      SUM(NetAmount) AS NetSales, 
      SUM(InsAmount) AS InsSales, 
      SUM(CancelRevenue) AS CXSales, 
      SUM(OtherAmount) AS OtherSales, 
      SUM(CXVALUE) AS CXValue 
FROM  dbo.B101BookingsDetails AS B101BookingsDetails 
WHERE BOOKED <= DateAdd(year, @YearToGet - Year(getdate()), 
                 DateAdd(day, DateDiff(day, 1, getdate()), 0) )
  AND @YearToGet
GROUP BY SDESCR, DYYYY, DIVISION 
HAVING      (DYYYY = @YearToGet) 
ORDER BY DIVISION, SDESCR, DYYYY

Answer 1

一些笔记。首先，你不应该使用“TOP 100 PERCENT”。它没有任何好处。如果您尝试在View中使用它，您应该知道在查询View时使用带有ORDER BY的TOP 100 PERCENT将无法保证顺序。其次，您的整数值似乎有问题，因为与DateDiff(d,0, <date>)相比，它们已经过了两天。我在使用BD.Booked = N.DateInt - 2的Where子句中对此进行了补偿，但您应该查看原因。

Declare @YearToGet int
Set @YearToGet = 2008

;With RawData As
    (
    Select 39503 As Booked
    Union All Select 39509
    Union All Select 39535
    Union All Select 39620
    Union All Select 39791
    Union All Select 39838

    )
    , Numbers As 
    (
    Select 0 As Value, Year(GetDate()) As [Year]
        , Cast( DateDiff(d,0,GetDate()) as datetime ) As [Date]
        , DateDiff(d,0,GetDate()) As [DateInt]
    Union All 
    Select Value + 1, [Year] - 1
        , DateAdd(yyyy, -1, [Date])
        , DateDiff(d, 0, DateAdd(yyyy, -1, [Date]))
    From Numbers
    Where Value <= ( Year(GetDate()) - @YearToGet )
    )
Select DIVISION, SDESCR, DYYYY

    , SUM(OtherAmount) AS OtherSales
    , SUM(CXVALUE) AS CXValue
From dbo.B101BookingsDetails As BD
    Join Numbers As N
        On Cast(N.[Year] As char(4)) = BD.DYYYY
Where BD.Booked = N.DateInt - 2
Group By DIVISION, SDESCR, DYYYY

Answer 2

昨天

convert(varchar, getDate()-1, 101)

一年前从昨天开始

convert(varchar, dateadd(year, -1, getDate()-1), 101)

Answer 3

尝试：

Declare @YearToget Integer 
Set @yearToGet = 2008

  Select DateAdd(year, @YearToGet - Year(getdate()), 
         DateAdd(day, DateDiff(day, 1, getdate()), 0) )

在您的查询中：

   Where Booked = DateAdd(year, 2008- Year(getdate()), 
             DateAdd(day, DateDiff(day, 1, getdate()), 0) )
      Or Booked = DateAdd(year, 2009- Year(getdate()), 
             DateAdd(day, DateDiff(day, 1, getdate()), 0) )
      Or Booked = DateAdd(year, 2010- Year(getdate()), 
             DateAdd(day, DateDiff(day, 1, getdate()), 0) )
      Or Booked = DateAdd(year, 2011- Year(getdate()), 
             DateAdd(day, DateDiff(day, 1, getdate()), 0) )

或

   Where Booked In
      (DateAdd(year, 2008- Year(getdate()), 
             DateAdd(day, DateDiff(day, 1, getdate()), 0) ),
       DateAdd(year, 2009- Year(getdate()), 
             DateAdd(day, DateDiff(day, 1, getdate()), 0) ),
       DateAdd(year, 2010- Year(getdate()), 
             DateAdd(day, DateDiff(day, 1, getdate()), 0) ),
       DateAdd(year, 2011- Year(getdate()), 
             DateAdd(day, DateDiff(day, 1, getdate()), 0) ) )

上面的查询，重写：

Declare @YearToget Integer  
Set @yearToGet = 2008  
Select Division, SDESCR,        
    DYYYY, Sum(APRICE) Sales, 
    Sum(PARTY) AS PAX,        
    Sum(NetAmount) NetSales,        
    Sum(InsAmount) InsSales,        
    Sum(CancelRevenue) CXSales,        
    Sum(OtherAmount) OtherSales,        
    Sum(CXVALUE) CXValue  
From dbo.B101BookingsDetails 
Where Booked <= DateAdd(year, @YearToGet - Year(getdate()),                   
                DateAdd(day, DateDiff(day, 1, getdate()), 0) )      
-- AND @YearToGet -- This line appears to be incomplete
Group By SDESCR, DYYYY, Division
Having (DYYYY = @YearToGet)  
Order By Division, SDESCR, DYYYY

Answer 4

select getdate() /* Today */
select dateadd(day, -1, getdate()) /* Yesterday */
select dateadd(year, -1, dateadd(day, -1, getdate())) /* 1 year ago yesterday */
