如何在另一個數據表中的數據表上的每個循環

Question

我有一個網絡民意調查應用程序，它讀取和處理來自sql server後端的訂單並插入到windss（jda）中。

1）I來自未加工
2）然後我需要的命令分成兩組
在SQL Server表中讀取所有的命令流 - 組1個訂單束試劑盒（ 1個爲了與幾個亞目）
- 組2個僅僅是訂單沒有束試劑盒
3）然後每個訂單處理後我需要更新isprocessed SQL字段設置爲1

1）代碼，用於讀取所有訂單

Frmmain.vb

dt = WebDatabase.GetAllOrdersFromDatabase()**'this method is below** 

For Each drow In dt.Rows 
    If CDbl(WinDSSStoreNumber) = 123 Or CDbl(WinDSSStoreNumber) = 124 Then 
    ' Store 123 and 124 = customer service - only orders with qualifying source codes 

我的問題是：

上述每個檢查，如果賣場爲123或124，但現在我要實現的另一個每個循環讀取所有InvoiceHeader_Id然後檢查數據表中的第二個字段，然後檢查它是否有捆綁工具包，如果它沒有，然後處理它並更新數據表中的最後一個isprocessed字段，則不處理任何捆綁工具包的訂單，並且對於那些更新進行處理。請任何幫助慷慨讚賞，請在下面的評論中問我任何問題，然後再標記我的問題。

WebData.vb

Public Function GetAllOrdersFromDatabase() As DataTable 
      DrivePath = "C:\Users\somjething\Documents\files\somefiles\" 
      Dim ds As DataTable = Nothing 
      WinDSS.connectionString = ConfigurationManager.AppSettings("WinDSS_Connection").Replace("%DrivePath%", DrivePath) 
      ds = WinDSS.GetSysMst() 

      If ds.Rows.Count > 0 Then 
       WinDSSStoreNumber = ds.Rows(0)("store_no") 

      End If 
      Dim dt As New DataTable() 
      Dim conn As New SqlConnection(ConfigurationManager.AppSettings("WebData_Connection") & ConfigurationManager.AppSettings("WebDataSource")) 
      Dim cmd As SqlCommand 
      Dim da As New SqlDataAdapter 
      conn.Open() 
      cmd = conn.CreateCommand() 
      cmd.CommandType = CommandType.Text 
     cmd.CommandText= SELECT InvoiceDetail_Id, InvoiceHeader_Id, ActualFreightCharge, AmountCollected, 
     ChargedActualFreight, CollectedExternally, CollectedThroughAR, DateInvoiced, InvoiceNo, 
     InvoiceType, LineSubTotal, MasterInvoiceNo, OrderInvoiceKey, Reference1, TotalAmount, 
     TotalTax, isprocessed, storetoprocess 
      FROM dbo.InvoiceHeader 
     WHERE (isprocessed = 0) AND (storetoprocess = N'123') 
    da.SelectCommand = cmd 
     da.Fill(dt) 
     conn.Close() 

     Return dt 
    End Function 

Additoinal信息

這是我的經理給我的信息：

循環throught下面每個

SELECT InvoiceDetail_Id, InvoiceHeader_Id, ActualFreightCharge, AmountCollected, 
ChargedActualFreight, CollectedExternally, CollectedThroughAR, DateInvoiced, InvoiceNo, 
InvoiceType, LineSubTotal, MasterInvoiceNo, OrderInvoiceKey, Reference1, TotalAmount, 
TotalTax, isprocessed, storetoprocess 
FROM dbo.InvoiceHeader WHERE (isprocessed = 0) AND (storetoprocess = N'195') 

使用以上InvoiceHeader_Id爲l完成所有訂單信息。處理每個包（包/）

SELECT InvoiceHeader_Id, LineDetails_Id, LineDetail_Id, OrderLine_Id, GiftFlag, [References], 
GiftWrap, IsBundleParent, KitCode, KitQty, LevelOfService, LineSeqNo, LineType, 
MaxLineStatus, MaxLineStatusDesc, MinLineStatus, MinLineStatusDesc, MinShipByDate, 
OpenQty, OrderHeaderKey, OrderLineKey, OrderedQty, OriginalOrderedQty, OtherCharges, 
OverallStatus, PipelineKey, PrimeLineNo, ReceivingNode, RemainingQty, ReqCancelDate, 
ReqDeliveryDate, 
ReqShipDate, SCAC, ScacAndService, ScacAndServiceKey, ShipNode, ShipToID, ShipToKey, 
StatusQuantity, SubLineNo, SubstituteItemID, isprocessed 
FROM dbo.OrderLine 
WHERE (isprocessed = 0) AND (InvoiceHeader_Id = 13) AND (IsBundleParent = 'Y') 
ORDER BY PrimeLineNo, SubLineNo 

對於低於上述列表查詢的每個記錄，並添加作爲零（0）美元金額。成本與上述記錄的信息相關聯（您可能需要查詢表格以獲取值） 從上述記錄中獲取OrderLineKey，並在下面查詢以獲取關聯的子項目。

SELECT TOP (100) PERCENT dbo.BundleParentLine.InvoiceHeader_Id AS BPL_InvoiceHeader_Id, 
dbo.BundleParentLine.LineDetails_Id AS BPL_LineDetails_Id, dbo.BundleParentLine.LineDetail_Id AS BPL_LineDetail_Id, dbo.BundleParentLine.OrderLine_Id AS BPL_OrderLine_Id, dbo.BundleParentLine.BundleParentLine_id, dbo.BundleParentLine.SubLineNo AS BPL_SubLineNo, dbo.BundleParentLine.PrimeLineNo AS BPL_PrimeLineNo, dbo.BundleParentLine.OrderLineKey AS BPL_OrderLineKey, dbo.OrderLine.* 
FROM dbo.BundleParentLine INNER JOIN dbo.OrderLine ON dbo.BundleParentLine.OrderLine_Id = dbo.OrderLine.OrderLine_Id AND dbo.BundleParentLine.LineDetail_Id = dbo.OrderLine.LineDetail_Id AND dbo.BundleParentLine.LineDetails_Id = dbo.OrderLine.LineDetails_Id AND dbo.BundleParentLine.InvoiceHeader_Id = dbo.OrderLine.InvoiceHeader_Id 
WHERE (dbo.BundleParentLine.OrderLineKey = N'76873264832') AND (dbo.BundleParentLine.InvoiceHeader_Id = 13) AND (dbo.BundleParentLine.LineDetails_Id = 6) AND (dbo.OrderLine.isprocessed = 0) 
ORDER BY BPL_PrimeLineNo, BPL_SubLineNo 

處理之後，設置isprocessed = 1

使用上述InvoiceHeader_Id循環throught所有的加工

SELECT InvoiceHeader_Id, LineDetails_Id, LineDetail_Id, OrderLine_Id, GiftFlag, [References], 
GiftWrap, IsBundleParent, KitCode, KitQty, LevelOfService, LineSeqNo, 
LineType, 
MaxLineStatus, MaxLineStatusDesc, MinLineStatus, MinLineStatusDesc, MinShipByDate, 
OpenQty, OrderHeaderKey, OrderLineKey, OrderedQty, 
    OriginalOrderedQty, 
OtherCharges, OverallStatus, PipelineKey, PrimeLineNo, ReceivingNode, RemainingQty, 
ReqCancelDate, ReqDeliveryDate, ReqShipDate, SCAC, 
ScacAndService, 
ScacAndServiceKey, ShipNode, ShipToID, ShipToKey, StatusQuantity, 
SubLineNo, SubstituteItemID, isprocessed 
FROM dbo.OrderLine 
WHERE (isprocessed = 0) AND (InvoiceHeader_Id = 13) AND (IsBundleParent <> 'Y') 
ORDER BY PrimeLineNo, SubLineNo 

後的順序信息，設置isprocessed = 1

Answer 1

這是不是一個答案，但我想提出這個提示你做一些澄清，這在評論中是不實際的。

首先，接近 Visual Studio和打開SQL Server Management Studio並連接到數據庫

我們將建立一些select語句來獲取數據回來，然後我們可以想想UPDATE語句

您發佈的第一個查詢會爲您提供商店195的未處理標題（直接來自您的帖子）。我不知道你是否想爲所有商店做這件事。將其粘貼到SSMS並運行它

SELECT H.* 
FROM dbo.InvoiceHeader H 
WHERE H.isprocessed = 0 AND H.storetoprocess = N'195' 

現在，這第二個查詢爲您提供未處理的行鍼對頭部有IsBundleParent =「Y」。

看！沒有循環！

SELECT H.*, L.* 
FROM dbo.InvoiceHeader H 
INNER JOIN 
dbo.OrderLine L 
ON L.InvoiceHeader_Id = H.InvoiceHeader_Id 
WHERE H.isprocessed = 0 AND H.storetoprocess = N'195' 
AND L.isprocessed = 0 AND L.IsBundleParent = 'Y' 

然後在你的解釋，你有對於低於上述列表查詢每個記錄，並添加零（0），這是沒有意義的，我金額所以也許你可以澄清

現在我們將添加第三個查詢中增加了BundleParentLine（它確實有它的內部連接了，但是這是一個非常奇怪的連接字段列表）

SELECT H.*, L.*, BPL.* 
FROM dbo.InvoiceHeader H 
INNER JOIN 
dbo.OrderLine L 
ON L.InvoiceHeader_Id = H.InvoiceHeader_Id 
INNER JOIN 
dbo.BundleParentLine BPL 
ON BPL.OrderLine_Id = L.OrderLine_Id 
AND BPL.LineDetail_Id = L.LineDetail_Id 
AND BPL.LineDetails_Id = L.LineDetails_Id 
AND BPL.InvoiceHeader_Id = L.InvoiceHeader_Id  
WHERE H.isprocessed = 0 AND H.storetoprocess = N'195' 
AND L.isprocessed = 0 AND L.IsBundleParent = 'Y' 

然後在你的解釋，你有P上之後rocessed，set isprocessed = 1，但是這裏的'處理'是什麼？它只是將它設置爲在表格中處理？

要做到這一點，你只需寫一條UPDATE聲明。這裏有一種方法來更新頭部信息（不要運行它，直到我們明白你想要做什麼爲止）。這裏的問題是您想要設置同時處理的標題和行嗎？

UPDATE InvoiceHeader 
SET Processed = 1 
WHERE isprocessed = 0 AND storetoprocess = N'195' 

你有第四個查詢似乎佔IsBundleParent <> 'Y'情況

再次，我們需要知道什麼加零（0）金額和處理意味着再往前走。
