减少 T-SQL 查询的运行时间

Question

-- WITH POD 导致了问题，删除此代码将 2 年的拉取时间减少到 3 分钟。 将发布新问题以找出包含 POD 数据的最佳方法。

--为清楚起见进行编辑，我是这些表的只读用户。

我编写了以下查询，但执行需要很长时间（20 分钟）。 目前限制为 1 个月，但用户希望至少 1 年，最好是 2 年。我认为这会将时间扩展到数小时。 任何人都可以看看让我知道是否有我没有使用的 BKM 来提高性能？ 或者对于这种大小的报告是否有更好的方法？ 2 年后，它将从 17 个表中返回约 100K 行。

Answer 1

CTE 只是语法
我怀疑CTE被评估了很多次
使用 indexe(s) 将 CTE 实体化为 #temp，使其运行一次

这个演员会伤害它
使这些列成为真实日期并为它们编制索引

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

where 否定左边，所以你可以做一个 join

另外，MAX(Load_Date) 可以匹配另一批货物

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
)

把它拉到连接中

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)
