SQL 返回同一年的最后 30 条记录

Question

In my query I want to return only the records that saved in last 30 days within same year but my query returns all the records that happened in last 30 days from today's month and day regardless of the year. I don't know what the reason I tried the condition in smaller query and it gives right result.

select top 10000 
      cb.billNo , MAX(cb.subCategoryID) subCategory ,
      Max(cb.cateogryID) categoryID ,
      MAX(tracking.date ) trackingDate,

      Max(Station.Code) Dest,Max(cb.picesCount) PieceCount, 
      Max(case when cb.productCount > 1 then 1 else 0 end) isMultiProduct ,
      Max(case when tt.ID = 1 and (cb. subCategoryID = 65 or cb. 
      subCategoryID 
      = 56) then 1 else 0 end) isReceived,
      
from CustomerBillss cb
     join Tracking on cw.billNo = Tracking.billNo
     join trackingtype tt on Tracking.TrackingTypeID = tt.ID
     join Station on cb.destinationStationID = Station.ID

where 
tracking.date > dateadd(dd,-30,cast(getdate() as date))
--(YEAR(tracking.Date) = YEAR(GETDATE()) AND
--tracking.Date >= DATEADD(day,-30,GETDATE()))
AND
cb. cateogryID in (1, 3)
AND Tracking.TrackingTypeID not in (8 , 4 ,20) 
AND cb.subCategoryID != 30 or (
   subCategoryID = 30 and cb.DestinationStationID = tracking.StationID)
group by cb.billNo;

Just uncomment the year filter in your select

select top 10000 
          cb.billNo , MAX(cb.subCategoryID) subCategory ,
          Max(cb.cateogryID) categoryID ,
          MAX(tracking.date ) trackingDate,
    
          Max(Station.Code) Dest,Max(cb.picesCount) PieceCount, 
          Max(case when cb.productCount > 1 then 1 else 0 end) isMultiProduct ,
          Max(case when tt.ID = 1 and (cb. subCategoryID = 65 or cb. 
          subCategoryID 
          = 56) then 1 else 0 end) isReceived,
          
    from CustomerBillss cb
         join Tracking on cw.billNo = Tracking.billNo
         join trackingtype tt on Tracking.TrackingTypeID = tt.ID
         join Station on cb.destinationStationID = Station.ID
    
    where 
    tracking.date > dateadd(dd,-30,cast(getdate() as date))
    (YEAR(tracking.Date) = YEAR(GETDATE()) AND
    --tracking.Date >= DATEADD(day,-30,GETDATE()))
    AND
    cb. cateogryID in (1, 3)
    AND Tracking.TrackingTypeID not in (8 , 4 ,20) 
    AND cb.subCategoryID != 30 or (
       subCategoryID = 30 and cb.DestinationStationID = tracking.StationID)
    group by cb.billNo;
