日付を取得し、過去7日間にデポにスキャンされたが、指定された日付までにスキャンアウトされなかったパレットの数を報告するSQLクエリがあります。実行には約1秒かかります。過去14日間、この番号を（SSRSレポートを使用して）報告する必要があります。ただし、CTEまたは一時テーブルを作成してレポートする日付を生成すると、10秒（約10日付）ではなく、3分以上になります。

お知らせ下さい。

単一の日付レポートは次のとおりです。

DECLARE @back integer
SET @back = 7
Declare @testDate DateTime
SET @testDate = '2012-10-09'
--opening balance query
select count(p.PalletID) as Opening_Balance
FROM [POSTALE].[dbo].[Pallet] p
join [POSTALE].[dbo].[Tracking] t on t.PalletID = p.PalletID
--scan was before indicated day
where CAST(DateAdd(hour, -6, t.TrackDateTime) as DATE) <= @testDate
--scan was after number of days to look back
and CAST(DateAdd(hour, -6, t.TrackDateTime) as DATE) >= dateadd(day, 0 - @back, @testDate)
--scanned into hub (get only the earliest occurence)
and t.TrackingID = (select top 1 tr.TrackingID from [POSTALE].[dbo].[Tracking] tr 
                where tr.TrackCode in ('SCAN OFF TRUNK HUB', 'DAYS') 
                and tr.PalletID = t.PalletID order by tr.TrackingID)
--not scanned out of hub by the indicated day
and (select count(tr.TrackingID) from [POSTALE].[dbo].[Tracking] tr where t.PalletID = tr.PalletID and 
    CAST(DateAdd(hour, -6, tr.TrackDateTime) as DATE) <= @testDate and tr.TrackCode in 
    ('SCAN ONTO TRUNK DEPOT', 'SCAN OFF TRUNK DEPOT', 'SECURITY SCAN AT DEPOT', 'SCAN OFF TRUNK DEPOT', 'SCANNER BROKEN',
    'SCAN ON DEPOT VEHICLE', 'POD ADDED','NO POD ADDED')) = 0

CTEと結合するためのコードは次のとおりです。

DECLARE @back integer
SET @back = 7
declare @start_date as date;
set @start_date = cast(getdate() - 14 as date);
declare @end_date as date;
set @end_date = cast(getdate() as date);
WITH DateList AS
(
    SELECT @start_date AS start_date
    UNION ALL
    SELECT DATEADD(DAY, 1, start_date)
    FROM DateList
    WHERE DATEADD(DAY, 1, start_date) < @end_date
)
SELECT
    (select count(p.PalletID) as Opening_Balance
...
,datediff(DAY, d.start_date, getdate()) as daysBack
from DateList d
order by d.start_date

..そしてこれが一時テーブルのバージョンです：

DECLARE @back integer
SET @back = 7
--hours into day that get pushed back to previous day
DECLARE @dayStart integer
set @dayStart = 12
--today + 12 hours as datetime
Declare @date12 as datetime
set @date12 = DateAdd(hour, @dayStart, cast(cast(getdate() as date) as datetime))
--temporary table to create list of dates to report on
DECLARE @DateList TABLE(
        DayDate DateTime
)
insert into @DateList (DayDate) Select DateAdd(day, - 14, @date12) where datepart(weekday, getdate() - 14) <> 7 and datepart(weekday, getdate() - 14) <> 1
insert into @DateList (DayDate) Select DateAdd(day, - 13, @date12) where datepart(weekday, getdate() - 13) <> 7 and datepart(weekday, getdate() - 13) <> 1
insert into @DateList (DayDate) Select DateAdd(day, - 12, @date12) where datepart(weekday, getdate() - 12) <> 7 and datepart(weekday, getdate() - 12) <> 1
insert into @DateList (DayDate) Select DateAdd(day, - 11, @date12) where datepart(weekday, getdate() - 11) <> 7 and datepart(weekday, getdate() - 11) <> 1
insert into @DateList (DayDate) Select DateAdd(day, - 10, @date12) where datepart(weekday, getdate() - 10) <> 7 and datepart(weekday, getdate() - 10) <> 1
insert into @DateList (DayDate) Select DateAdd(day, - 9, @date12) where datepart(weekday, getdate() - 9) <> 7 and datepart(weekday, getdate() - 9) <> 1
insert into @DateList (DayDate) Select DateAdd(day, - 8, @date12) where datepart(weekday, getdate() - 8) <> 7 and datepart(weekday, getdate() - 8) <> 1
insert into @DateList (DayDate) Select DateAdd(day, - 7, @date12) where datepart(weekday, getdate() - 7) <> 7 and datepart(weekday, getdate() - 7) <> 1
insert into @DateList (DayDate) Select DateAdd(day, - 6, @date12) where datepart(weekday, getdate() - 6) <> 7 and datepart(weekday, getdate() - 6) <> 1
insert into @DateList (DayDate) Select DateAdd(day, - 5, @date12) where datepart(weekday, getdate() - 5) <> 7 and datepart(weekday, getdate() - 5) <> 1
insert into @DateList (DayDate) Select DateAdd(day, - 4, @date12) where datepart(weekday, getdate() - 4) <> 7 and datepart(weekday, getdate() - 4) <> 1
insert into @DateList (DayDate) Select DateAdd(day, - 3, @date12) where datepart(weekday, getdate() - 3) <> 7 and datepart(weekday, getdate() - 3) <> 1
insert into @DateList (DayDate) Select DateAdd(day, - 2, @date12) where datepart(weekday, getdate() - 2) <> 7 and datepart(weekday, getdate() - 2) <> 1
insert into @DateList (DayDate) Select DateAdd(day, - 1, @date12) where datepart(weekday, getdate() - 1) <> 7 and datepart(weekday, getdate() - 1) <> 1
SELECT
    (select count(p.PalletID) as Opening_Balance
...
,datediff(DAY, d.DayDate, getdate()) as daysBack
from @DateList d
order by d.DayDate

明らかに大きな要因となる可能性のあるインデックス付けについては説明していませんが、私が気付いた1つのことは、WHERE句にsargableではない要素が含まれていることです。

たとえば、次のように変更してみてください。

where CAST(DateAdd(hour, -6, t.TrackDateTime) as DATE) <= @testDate

に

where t.TrackDateTime < dateadd(hour, 6, dateadd(day, 1, @testDate))

この行でも同様のことを行う必要があります。

and CAST(DateAdd(hour, -6, t.TrackDateTime) as DATE) >= dateadd(day, 0 - @back, @testDate)
