我如何使一个增量1串行基于多个条件Sql服务器?

Question

编辑#1:代码可以包含随机字母和数字，如"A123BC56xa">

编辑#2:我试过这个subquery，但它给了我Syntax Error

SELECT DocDtls.Warehouse, Transactions.Code, DocDtls.zDate, Transactions.ID, Transactions.QtyIn, Transactions.QtyOut, Transactions.BalanceAfter, (SELECT Count("*") FROM Transactions AS B WHERE  B.[ID]<A.[ID] And B.[Warehouse] = A.[Warehouse] And B.[Code] = A.[Code])+1 AS Serial
FROM DocDtls INNER JOIN Transactions ON DocDtls.DocNum = Transactions.DocNum
ORDER BY DocDtls.Warehouse, Transactions.Code, DocDtls.zDate, Transactions.ID As A;

我有这个查询

SELECT DocDtls.Warehouse, DocDtls.zDate, Transactions.Code, Transactions.ID, Transactions.QtyIn, Transactions.QtyOut, Transactions.BalanceAfter
FROM DocDtls INNER JOIN Transactions ON DocDtls.DocNum = Transactions.DocNum
ORDER BY DocDtls.Warehouse, Transactions.Code, DocDtls.zDate, Transactions.ID;

这是当前的查询结果:

Warehouse | zDate   |   ID  |   Code    |   QtyIn   |QtyOut |   BalanceAfter
MainWh  |   20-03-2022  |   7   |   00001   |   5000|   0   |   0
MainWh  |   21-03-2022  |   8   |   00001   |   0   |   1000|   0
MainWh  |   20-03-2022  |   9   |   00002   |   7000|   0   |   0
MainWh  |   21-03-2022  |   10  |   00002   |   0   |   2500|   0
Wh1     |   21-03-2022  |   1   |   00001   |   1000|   0   |   0
Wh1     |   25-04-2022  |   5   |   00001   |   0   |   250 |   0
Wh1     |   25-04-2022  |   5   |   00001   |   0   |   300 |   0
Wh1     |   21-03-2022  |   2   |   00002   |   2500|   0   |   0
Wh1     |   25-04-2022  |   6   |   00002   |   0   |   500 |   0

我需要添加一个类似ID的串行列，但根据Code和Warehouse增加1，结果应该像

Warehouse | zDate   |   ID  |   Code    |   QtyIn   |QtyOut |   BalanceAfter|   Serial
MainWh  |   20-03-2022  |   7   |   00001   |   5000|   0   |   0|               1  
MainWh  |   21-03-2022  |   8   |   00001   |   0   |   1000|    0|              2  
MainWh  |   20-03-2022  |   9   |   00002   |   7000|   0   |    0|              1  
MainWh  |   21-03-2022  |   10  |   00002   |   0   |   2500|   0|               2  
Wh1     |   21-03-2022  |   1   |   00001   |   1000|   0   |   0    |           1  
Wh1     |   25-04-2022  |   5   |   00001   |   0   |   250 |   0|               2  
Wh1     |   25-04-2022  |   5   |   00001   |   0   |   300 |   0|               3  
Wh1     |   21-03-2022  |   2   |   00002   |   2500|   0   |   0    |           1
Wh1     |   25-04-2022  |   6   |   00002   |   0   |   500 |   0|               2  

我用的是sqlserver 2014，提前谢谢。

Answer 1

SQL server 2014非常老旧，应该尽快更换。

你可以使用像row_number这样的窗口函数来实现你的目标

CREATE TABLE DocDtls 
([Warehouse] varchar(6), [zDate] varchar(10), [ID] int, [Code] int, [QtyIn] int, [QtyOut] int, [BalanceAfter] int)
;

INSERT INTO DocDtls 
([Warehouse], [zDate], [ID], [Code], [QtyIn], [QtyOut], [BalanceAfter])
VALUES
('MainWh', '20-03-2022', 7, 00001, 5000, 0, 0),
('MainWh', '21-03-2022', 8, 00001, 0, 1000, 0),
('MainWh', '20-03-2022', 9, 00002, 7000, 0, 0),
('MainWh', '21-03-2022', 10, 00002, 0, 2500, 0),
('Wh1', '21-03-2022', 1, 00001, 1000, 0, 0),
('Wh1', '25-04-2022', 5, 00001, 0, 250, 0),
('Wh1', '25-04-2022', 5, 00001, 0, 300, 0),
('Wh1', '21-03-2022', 2, 00002, 2500, 0, 0),
('Wh1', '25-04-2022', 6, 00002, 0, 500, 0)
;

GO

受影响的9行

SELECT *,
ROW_NUMBER() OVER( PARTITION BY [Warehouse],[Code] ORDER BY [ID]) as Serial
FROM DocDtls

GO

Warehouse | zDate | ID | Code | QtyIn | QtyOut | BalanceAfter | Serial:-------- | :--------- | -: | ---: | ----: | -----: | -----------: | -----:MainWh | 20-03-2022 | 7 | 1 | 5000 | 0 | 0 | 1MainWh | 21-03-2022 | 8 | 1 | 0 | 1000 | 0 | 2MainWh | 20-03-2022 | 9 | 2 | 7000 | 0 | 0 | 1MainWh | 21-03-2022 | 10 | 2 | 0 | 2500 | 0 | 2Wh1 | 21-03-2022 | 1 | 1 | 1000 | 0 | 0 | 1Wh1 | 25-04-2022 | 5 | 1 | 0 | 250 | 0 | 2Wh1 | 25-04-2022 | 5 | 1 | 0 | 300 | 0 | 3Wh1 | 21-03-2022 | 2 | 2 | 2500 | 0 | 0 | 1Wh1 | 25-04-2022 | 6 | 2 | 0 | 500 | 0 | 2

Answer 2

如果Code列始终是'00001'，'00002'，'00101'等格式，则可以使用强制转换。

SELECT DocDtls.Warehouse, DocDtls.zDate, Transactions.Code, Transactions.ID, Transactions.QtyIn, Transactions.QtyOut, Transactions.BalanceAfter
FROM DocDtls INNER JOIN Transactions ON DocDtls.DocNum = Transactions.DocNum
ORDER BY DocDtls.Warehouse, Transactions.Code, DocDtls.zDate, Transactions.ID, CAST(Transactions.Code AS INT) AS Serial;
