记录的更新取决于sql中的数量
我有2个这样的查询：
select
F_In_Out_Date ,
F_QTY, F_lot_number, F_BillOf_entryNumber
from
T_Tra_Transaction
where
F_lot_number = '160427A161'
and F_Stock_Type = 'IN'
select
F_In_Out_Date ,
F_QTY, F_lot_number, F_BillOf_entryNumber
from
T_Tra_Transaction
where
F_lot_number = '160427A161'
and F_Stock_Type = 'out'
我的输出如下：
我的第一个查询显示In Qty，我的第二个查询显示OUT数量取决于我的BOE编号。在我的结果中，首先100个数量来自Billof条目号14-2-4-15451983，因此在我的状态查询中，我需要使用以上条目号码更新前100个数量。另外70个数量需要更新其他条目号（14-2-4-15546475）。我怎样才能做到这一点？
我做了一个查询，但是用第一个条目号更新所有记录。
update tout
set F_BillOf_entryNumber = tin.F_BillOf_entryNumber
from
(select
F_QTY, F_lot_number, F_BillOf_entryNumber,
rn = row_number() over (partition by F_QTY, F_lot_number order by F_In_Out_Date desc)
from
T_Tra_Transaction
where
F_Stock_Type = 'out') tout
join
(select
F_QTY, F_lot_number, F_BillOf_entryNumber,
rn = row_number() over (partition by F_QTY, F_lot_number order by F_In_Out_Date desc)
from
T_Tra_Transaction
where
F_Stock_Type = 'IN') tin on tout.F_lot_number = tin.F_lot_number

它有些复杂。你需要一个递归的CTE才能实现它。
上述架构：
CREATE TABLE #T_TRA_TRANSACTION (F_Id INT IDENTITY PRIMARY KEY
,F_IN_OUT_DTE DATETIME
,F_QTY INT
,F_LOT_NUMBER VARCHAR(50)
,F_BILLOF_ENTRYNUMBER VARCHAR(50)
,F_STOCK_TYPE VARCHAR(10))
INSERT INTO #T_TRA_TRANSACTION
SELECT '2016-05-31',15,'160427A161','14-2-4-15451983','IN'
UNION ALL
SELECT '2016-05-31',5,'160427A161','14-2-4-15451983','IN'
UNION ALL
SELECT '2016-08-02',10,'160427A161','14-2-4-15546475','IN'
UNION ALL
SELECT '2016-08-02',10,'160427A161','14-2-4-15546475','IN'
UNION ALL
SELECT '2016-08-02',5,'160427A161','14-2-4-15546475','IN'
UNION ALL
SELECT '2016-08-14',5,'160427A161','14-2-4-15546475','OUT'
UNION ALL
SELECT '2016-08-14',5,'160427A161','14-2-4-15546475','OUT'
UNION ALL
SELECT '2016-08-14',5,'160427A161','14-2-4-15546475','OUT'
UNION ALL
SELECT '2016-08-14',5,'160427A161','14-2-4-15546475','OUT'
UNION ALL
SELECT '2016-08-18',5,'160427A161','14-2-4-15546475','OUT'
UNION ALL
SELECT '2016-08-18',5,'160427A161','14-2-4-15546475','OUT'
UNION ALL
SELECT '2016-08-18',5,'160427A161','14-2-4-15546475','OUT'
UNION ALL
SELECT '2016-08-18',5,'160427A161','14-2-4-15546475','OUT'
UNION ALL
SELECT '2016-08-18',5,'160427A161','14-2-4-15546475','OUT'
然后尝试以下查询。我已经添加了每个CTE的中间结果，以了解我们从中获取的内容
;WITH CTE_BILL_WISE AS(

您可以将最后一个选择更改为更新，如
UPDATE #T_TRA_TRANSACTION SET #T_TRA_TRANSACTION.F_BILLOF_ENTRYNUMBER = C4.F_BILLOF_ENTRYNUMBER
FROM CTE_OUT_QTY_SUM C3
INNER JOIN CTE_BILL_QTY_RANGE C4 ON C3.F_QTY BETWEEN C4.START_QTY AND C4.END_QTY
INNER JOIN #T_TRA_TRANSACTION ON #T_TRA_TRANSACTION.F_Id = C3.F_Id
