SQL查詢來計算基於給定的條件

我有一個股票的交易表這樣的剩餘運行餘額：SQL查詢來計算基於給定的條件

StockID Item TransDate TranType BatchNo Qty Price 
10001 ABC 01-Apr-2012 IN  71001000 200 750.0 
10002 ABC 02-Apr-2012 OUT    100  
10003 ABC 03-Apr-2012 IN  71001001 50 700.0 
10004 ABC 04-Apr-2012 IN  71001002 75 800.0 
10005 ABC 10-Apr-2012 OUT    125  
10006 XYZ 05-Apr-2012 IN  71001003 150 350.0 
10007 XYZ 05-Apr-2012 OUT    120  
10008 XYZ 15-Apr-2012 OUT    10  
10009 XYZ 20-Apr-2012 IN  71001004 90 340.0 
10010 PQR 06-Apr-2012 IN  71001005 50 510.0 
10011 PQR 15-Apr-2012 IN  71001006 60 505.0 
10012 MNO 01-Apr-2012 IN  71001007 76 410.0 
10013 MNO 11-Apr-2012 OUT    76

每個我的交易已經價格相關聯，並批號（批號）。現在我想通過先入先出（FIFO）規則計算剩餘數量，這意味着首先應該先進行調整。調整量後的剩餘餘額要針對每個IN事務同樣項目計算，如下所示：

StockID Item TransDate TranType BatchNo Qty Price RemainingQty 
10001 ABC 01-Apr-2012 IN  71001000 200 750.0 0   
10002 ABC 02-Apr-2012 OUT    100    
10003 ABC 03-Apr-2012 IN  71001001 50 700.0 25   
10004 ABC 04-Apr-2012 IN  71001002 75 800.0 75   
10005 ABC 10-Apr-2012 OUT    125    
10006 XYZ 05-Apr-2012 IN  71001003 150 350.0 20   
10007 XYZ 05-Apr-2012 OUT    120    
10008 XYZ 15-Apr-2012 OUT    10    
10009 XYZ 20-Apr-2012 IN  71001004 90 340.0 90   
10010 PQR 06-Apr-2012 IN  71001005 50 510.0 50   
10011 PQR 15-Apr-2012 IN  71001006 60 505.0 60   
10012 MNO 01-Apr-2012 IN  71001007 76 410.0 0   
10013 MNO 11-Apr-2012 OUT    76

正如我們可以從項ABC上表中，調整（125 + 100）後OUT見數量與使用FIFO的IN數量（100 + 50 + 75）相比，批次71001000的剩餘數量爲0，71001001爲25，批次71001002爲75.從剩餘數量可以推導出數值。

請幫助我使用任何方法（基於遊標或CTE或JOINS等）實現這一點預先感謝您的幫助。

要問的一個顯而易見的問題是爲什麼你沒有將BatchNo分配給OUT記錄？這會讓事情更容易解決你的問題。你的問題清楚地說明了這種關係，但是你的表格定義並不反映這一點。 – Brad

Hi @Brad批號只是一個創建的交易號碼，用於標識很多。但是，所有這些地塊都是混在一起發行的。但爲了會計目的，結果是必需的。 – Nagesh

親愛的@達文，謝謝你的回答，你是第一個解決方案的人。所有學分給你。讓我檢查並確認這一點。 – Nagesh

您的問題對於我如何應用FIFO邏輯不是很清楚。我假設你想將每個IN記錄與下一個OUT記錄相關聯（如果存在）。要做到這一點，你需要加入表上本身像下面

select 
    t1.BatchNo, 
    isnull(t1.Qty,0) as 'IN Qty', 
    isnull(t2.Qty,0) as 'OUT Qty', 
    isnull(t1.Qty,0) - isnull(t2.Qty,0) as 'Remaining Qty' 
from 
    tbl_test t1 
left join tbl_test t2 
    on t2.StockID = (t1.StockID + 1) 
    and t2.TranType = 'OUT' 
where 
    t1.TranType = 'IN'

結果將顯示你從你的問題前5條記錄爲ABC以下。

BatchNo | IN Qty | OUT Qty | Remaining Qty 
71001000 | 200 | 100  | 100 
71001001 | 50  | 0  | 50 
71001002 | 75  | 125  | -50

左側加入假設作品的StockID對中的每個記錄總是少了一個數比對應的輸出記錄。我個人認爲你的數據模型需要改進。

OUT記錄應該有分配BatchNo或訂購
添加日期時間字段用於處理IN/OUT存在的對同來的在創紀錄的
關聯添加時間戳字段順序的 StockID參考天

Hi @Brad，時間戳和日期時間存在於數據模型中，爲簡單起見，此處未顯示。但是BatchNo引用不存在，這就是數據模型設計的方式。請幫助達到所需的結果。 – Nagesh

如果您可以更多地闡明邏輯，我可以嘗試進一步回答我的答案。我不明白爲什麼你想要的結果中的第一條記錄在BatchNo 71001000的IN = 200和OUT = 100時具有'RemainingQty = 0'。我期望'RemainingQty = 100' – Brad

感謝您的回覆@Brad。對於ABC項目，有5個交易 - 3個IN和2個OUT。所有IN的淨流入量爲325，OUT流出淨流量爲225，剩餘淨流量爲100.這100個數量將根據FIFO分配給每個批次。由於200 Qty是第一個IN交易，因此它被取消。 – Nagesh
