尝试从ShipHead.Ship日期而不是所有记录中获取最后/最新记录如何使用此查询进行最后一次记录?
SELECT
OrderRel.ReqDate
,OrderHed.EntryPerson
,ShipHead.ShipDate
,Customer.Name
,ShipDtl.OrderNum
,ShipDtl.OrderLine
,ShipDtl.OrderRelNum
FROM
OrderHed
INNER JOIN OrderDtl
ON OrderHed.Company = OrderDtl.Company AND OrderHed.OrderNum = OrderDtl.OrderNum
INNER JOIN OrderRel
ON OrderDtl.Company = OrderRel.Company AND OrderDtl.OrderNum = OrderRel.OrderNum AND OrderDtl.OrderLine = OrderRel.OrderLine
INNER JOIN ShipDtl
ON OrderRel.Company = ShipDtl.Company AND OrderRel.OrderNum = ShipDtl.OrderNum AND OrderRel.OrderLine = ShipDtl.OrderLine AND OrderRel.OrderRelNum = ShipDtl.OrderRelNum
INNER JOIN ShipHead
ON ShipDtl.Company = ShipHead.Company AND ShipDtl.PackNum = ShipHead.PackNum
INNER JOIN Customer
ON ShipHead.Company = Customer.Company AND ShipHead.CustNum = Customer.CustNum
WHERE
OrderRel.OrderNum = 603205

您可以尝试以下方法。如果您想要每个参赛人员的最后日期记录,请转到B:
SELECT
X.ReqDate,
X.EntryPerson,
X.ShipDate,
X.Name,
X.OrderNum,
X.OrderLine,
X.OrderRelNum
FROM
(
SELECT
ORl.ReqDate,
OH.EntryPerson,
SH.ShipDate,
rn = row_number() OVER(ORDER BY SH.ShipDate DESC),
--rn = row_number() OVER(PARTITION BY OH.EntryPerson ORDER BY SH.ShipDate DESC) --<<B
C.Name,
SD.OrderNum,
SD.OrderLine,
SD.OrderRelNum
FROM
OrderHed OH
INNER JOIN OrderDtl OD ON
OH.Company = OD.Company AND
OH.OrderNum = OD.OrderNum
INNER JOIN OrderRel ORl ON
OD.Company = ORl.Company AND
OD.OrderNum = ORl.OrderNum AND
OD.OrderLine = ORl.OrderLine
INNER JOIN ShipDtl SD ON
ORl.Company = SD.Company AND
ORl.OrderNum = SD.OrderNum AND
ORl.OrderLine = SD.OrderLine AND
ORl.OrderRelNum = SD.OrderRelNum
INNER JOIN ShipHead SH ON
SD.Company = SH.Company AND
SD.PackNum = SH.PackNum
INNER JOIN Customer C ON
SH.Company = C.Company AND
SH.CustNum = C.CustNum
WHERE
ORl.OrderNum = 603205
) X
WHERE X.rn = 1
P.S。为什么不使用较短的别名 - 这是别名的一部分
