Question

以下SQL查找找到符合某些要求的订单，然后在此阶段创建一个带有发票行（_btblInvoiceLines）的新订单（InvNum），它只创建了基本信息。

DECLARE @gid varchar(50) SELECT @gid = newid()

INSERT INTO InvNum (DocType,DocState,AccountID,ucIDSOrdTempInvID) 
SELECT 4,1,AccountID,@gid 
FROM (SELECT DISTINCT AccountID 
      FROM InvNum 
      WHERE ubIDSOrdConsolOrder = '1' 
      AND DocState = '1' 
      AND DocType <> '5') A


INSERT INTO _btblInvoiceLines (iInvoiceID, iStockCodeID, fQuantity) 
SELECT AutoIndex, iStockCodeID, qty 
FROM (SELECT AutoIndex, iStockCodeID, qty 
      FROM (SELECT AutoIndex,AccountId,ucIDSOrdTempInvID 
            FROM InvNum
            WHERE ucIDSOrdTempInvID = @gid) T1 
      INNER JOIN (SELECT B.iStockCodeID,A.AccountID,sum(B.fQuantity) AS qty 
                  FROM (SELECT * 
                        FROM  InvNum  
                        WHERE ubIDSOrdConsolOrder = '1' 
                        AND DocState = '1' 
                        AND DocType <> '5') A    
                  INNER JOIN (SELECT * 
                              FROM _btblInvoiceLines) B ON A.AutoIndex = B.iInvoiceID 
                  GROUP BY iStockCodeID, AccountID) T2 ON T1.AccountId = T2.AccountID) T3

此后，InvNum列全部更新，这样可以正常工作。我的问题是以下内容，即更新新订单的_btblInvoiceLines和新订单的新行，匹配：WHERE ubIDSOrdConsolOrder = '1' AND DocState = '1' AND DocType <> '5'

这个FROM子句是不正确的：

SELECT D1.*
FROM (SELECT A.* 
      FROM _btblInvoiceLines A
      INNER JOIN (SELECT max(idInvoiceLines) as idInvoiceLines, iStockCodeID 
                  FROM _btblInvoiceLines 
                  GROUP BY iStockCodeID) B ON A.idInvoiceLines = B.idInvoiceLines) D1
      INNER JOIN (SELECT * 
                  FROM _btblInvoiceLines I1 
                  INNER JOIN (SELECT accountid,autoindex,ucIDSOrdTempInvID 
                              FROM InvNum 
                              WHERE ucIDSOrdTempInvID = @gid) I2 ON I1.iInvoiceID = I2.AutoIndex) D2 ON D1.iStockCodeID = D2.iStockCodeID 
      WHERE _btblInvoiceLines.idInvoiceLines = D2.idInvoiceLines

我迷失了如何制作D1。*从最新的原始_btblInvoiceLines中提取信息，该信息被添加到新订单D2中。我认为我能做到这一点的唯一方法是使用以下SELECT DISTINCT AccountID,ubIDSOrdConsolOrder FROM InvNum WHERE ubIDSOrdConsolOrder = '1' AND DocState = '1' AND DocType <> '5'，但我不知道如何正确地使用它。很抱歉，如果这是一个简单的问题，但我一直在寻找并尝试解决此问题2天，现在没有任何运气。

谢谢。

我的INNER JOIN顺序错误。我做了以下操作，现在可以正常工作了：

SELECT D1.*
FROM (SELECT DISTINCT AccountID, AutoIndex FROM InvNum WHERE ubIDSOrdConsolOrder = '1' AND DocState = '1' AND DocType <> '5') A1

  INNER JOIN (SELECT * FROM _btblInvoiceLines) D1 ON A1.AutoIndex = D1.iInvoiceID----

  INNER JOIN (SELECT max(idInvoiceLines) as idInvoiceLines, iStockCodeID FROM _btblInvoiceLines GROUP BY iStockCodeID) I1  ON D1.iStockCodeID = I1.iStockCodeID

  INNER JOIN (SELECT * FROM _btblInvoiceLines I1 INNER JOIN (select accountid,autoindex,ucIDSOrdTempInvID FROM InvNum where ucIDSOrdTempInvID = @gid) I2 ON I1.iInvoiceID=I2.AutoIndex) D2 ---- @gid
ON D1.iStockCodeID=D2.iStockCodeID

WHERE _btblInvoiceLines.idInvoiceLines = D2.idInvoiceLines

MSSQL INNER JOIN WHERE子句
