SQL将多个行插入第二个/子表

Question

我一直呆在整个下午，最后放弃了。 我需要每月定期为多个客户创建月度发票。

因此，我从[Customers-Main]表中获取了数据，并创建了我需要的所有[INVOICES]行。 但是，我无法让[客户-发票]正确填充每张发票。 应该发生的是，[发票-库存链接]填充有[客户-发票]的正确信息。 当前，每个客户项目都填充1张发票。

这是我到目前为止已到达的代码，将不胜感激地收到任何帮助。

ALTER PROCEDURE [aa test]

AS 

INSERT INTO dbo.[INVOICES] 
(
    CompanyName, InvoiceDate, PurchaseOrderNo, Terms
    , JobNumber, PrintableNotes, Initials
) 
SELECT dbo.[CUSTOMERS - Main].CompanyName
    , DATEADD(d, - 15, DATEADD(mm, DATEDIFF(m, 0, GETDATE()) + 1, 0)) AS Expr1
    , 'test3' AS pono, 7 AS terms, 0 AS jobno
    , 'We will attempt to collect this invoice by Direct Debit' AS printnotes
    , 'KA' AS initials 
FROM dbo.[CUSTOMERS - Main] 
INNER JOIN dbo.[CUSTOMERS - Invoices] 
ON dbo.[CUSTOMERS - Main].CustID = dbo.[CUSTOMERS - Invoices].CustID 
WHERE (dbo.[CUSTOMERS - Invoices].Annual <> 1) And 
    (dbo.[CUSTOMERS - Invoices].DayofMonth = 15) 
GROUP BY dbo.[CUSTOMERS - Main].CompanyName

SELECT @endInvoice=MAX(InvoiceNo) FROM INVOICES 

INSERT INTO dbo.[INVOICES - Stock Link] (InvoiceNo, StockID, SalePrice) 
SELECT @endinvoice, StockID, Price 
FROM dbo.[CUSTOMERS - Invoices]

您可以使用NikolaMarkovinović提到的OUTPUT子句：

ALTER PROCEDURE [aa test]

AS

-- Setup storage for the inserted keys
DECLARE @INVOICES TABLE (InvoiceNo int not null primary key)

INSERT INTO dbo.[INVOICES]
(
    CompanyName, InvoiceDate, PurchaseOrderNo, Terms
    , JobNumber, PrintableNotes, Initials
)
-- Grab the inserted keys
OUTPUT INSERTED.InvoiceNo INTO @INVOICES
SELECT dbo.[CUSTOMERS - Main].CompanyName
    , DATEADD(d, - 15, DATEADD(mm, DATEDIFF(m, 0, GETDATE()) + 1, 0)) AS Expr1
    , 'test3' AS pono, 7 AS terms, 0 AS jobno
    , 'We will attempt to collect this invoice by Direct Debit' AS printnotes
    , 'KA' AS initials
FROM dbo.[CUSTOMERS - Main]
INNER JOIN dbo.[CUSTOMERS - Invoices]
ON dbo.[CUSTOMERS - Main].CustID = dbo.[CUSTOMERS - Invoices].CustID
WHERE (dbo.[CUSTOMERS - Invoices].Annual <> 1) And
    (dbo.[CUSTOMERS - Invoices].DayofMonth = 15)
GROUP BY dbo.[CUSTOMERS - Main].CompanyName

INSERT INTO dbo.[INVOICES - Stock Link] (InvoiceNo, StockID, SalePrice)
 -- Not sure where StockID and Price come from
SELECT a.InvoiceNo, a.StockID, a.Price
FROM dbo.[CUSTOMERS - Invoices] a
    -- Join on the keys from above
    JOIN @INVOICES b ON a.InvoiceNo = b.InvoiceNo
