减少T-SQL查询的运行时间

- WITH POD导致问题，删除此代码减少了2年拉到3分钟。 将发布新问题以找出包含POD数据的最佳方式。

- 为了清晰起见，我是这些表的只读用户。

我写了下面的查询，但是执行需要很长时间（20分钟）。 它目前仅限于1个月，但用户希望至少1年，最好是2年。我认为这会将时间缩短到数小时。 任何人都可以看一下，如果有一个BKM我不会用来提高性能让我知道吗？ 或者，如果有更好的方法来处理这种规模的报告？在2年时，它将从17个表中返回~100K行。

CTE只是语法
我怀疑CTE被评估了很多次 使用索引将CTE物化为#temp，使其运行一次

这个演员会伤害它 将这些列设为真实日期并将其编入索引

ON CAST(FD.CALENDAR_DAY AS DATE) = CAST(GI.ACTUAL_PGI_DATE AS DATE)

在那里否定左边所以你可以加入

此外，MAX（Load_Date）可以在另一批货物上匹配

SELECT SHIPMENTS.Delivery
  ,SHIPMENTS.Shipment_Number
  ,PROOF_OF_DELIVERY.Shipping_Carrier
  ,PROOF_OF_DELIVERY.Tracking_Number
  ,PROOF_OF_DELIVERY.Ship_Method
  ,PROOF_OF_DELIVERY.POD_Signature
  ,PROOF_OF_DELIVERY.POD_Date
  ,PROOF_OF_DELIVERY.POD_Time
 FROM SHIPMENTS 
 JOIN PROOF_OF_DELIVERY
   ON SHIPMENTS.Shipment_Number = PROOF_OF_DELIVERY.Delivery_Or_Shipment
WHERE PROOF_OF_DELIVERY.Load_Date IN
(
    SELECT MAX(Load_Date)
    FROM PROOF_OF_DELIVERY
    GROUP BY Delivery_Or_Shipment
)

将其拉入联接

INNER JOIN dbo.Customer_View AS SOLD
  ON GI.SOLD_TO_CUSTOMER_ID = SOLD.CUSTOMER_CODE 
 AND GI.SOLD_TO_CUSTOMER_ID IN (0010000252,0010000898,0010001121,0010001409,0010001842,0010001852,0010001879,0010001977,0010001978,0010002021,0010002202,0010002227,0010002982,0010003118,0010003176,0010003294,0010005492,0010006904,0010007048,0010007080,0010010381,0010010572,0010010905,0010011999,0010012014,0010012048,0010012571,0010013124,0010013711,0010013713,0010013824,0010014180,0010014188,0010014333,0010015059,0010015313,0010015414,0010015541,0010015544,0010015550)
