我今天在T-sql中写了一个完全正常的查询。对于客户，我需要以XML格式提供数据。我尝试使用显式方法和路径方法，但没有任何成功。
我的查询如下：
select
allShopsItem.ShopCode as ShopCode
, allShopsItem.ItemCode as ItemCode
, allShopsItem.SupplyNumber as SupplyNumber
, CONVERT (date, GETDATE()-1) as Fulldate
, isnull(sales.SumQtyTransactions, 0) as Sales
, isnull(stock.Qty, 0) as Stock
, isnull(outstandingorders.sumQTY, 0) as Outstanding
from (
select
S.SHOP_CODE as ShopCode,
I.ITEM_CODE as ItemCode,
I.ITEM_NAME as ItemName,
CVI.CUSTVENDRELATION as SupplyNumber
from
BI_DWH_BC.D_SHOP S
CROSS JOIN BI_DWH_BC.D_ITEM I
INNER JOIN BI_STAGING.ERP_CUSTVENDEXTERNALITEM CVI
ON I.ITEM_CODE = CVI.ITEMID AND CVI.CUSTVENDRELATION = 900520
WHERE
I.ITEM_GRP_CODE = 'HW-ACC' /*and I.ITEM_CYCLE = 'Normaal'*/ and I.ROW_IS_CURRENT = 1
AND S.SHOP_TYPE IN ('Telenet Store','Telenet Concept Store')
AND S.SHOP_IS_CLOSED = 0
) as allShopsItem
LEFT OUTER JOIN (
SELECT
S.SHOP_CODE as ShopCode,
I.ITEM_CODE as ItemCode,
CAST(SUM(TR.TRANS_QUANTITY*-1) AS INTEGER) as SumQtyTransactions
FROM
BI_DWH_BC.F_TRANSACTION TR
INNER JOIN BI_DWH_BC.D_DATE D ON D.PK_DATE = TR.FK_TRANS_DATE
INNER JOIN BI_DWH_BC.D_SHOP S ON S.PK_SHOP = TR.FK_TRANS_SHOP
INNER JOIN BI_DWH_BC.D_ITEM I ON I.PK_ITEM = TR.FK_TRANS_ITEM
WHERE
D.DATE_FULLDATE = CONVERT (date, GETDATE()-1)
--TR.FK_TRANS_DATE = 20140702
GROUP BY
S.SHOP_CODE, I.ITEM_CODE
) as sales ON allShopsItem.ShopCode = sales.ShopCode AND allShopsItem.ItemCode = sales.ItemCode
LEFT OUTER JOIN (
SELECT
S.SHOP_CODE as ShopCode
, IT.ITEM_CODE as ItemCode
, SUM(SM.STMOV_QTY) Qty
FROM BI_DWH_BC.F_STOCK_MOVEMENT SM
INNER JOIN BI_DWH_BC.D_DATE D ON D.PK_DATE = SM.FK_STMOV_DATE
INNER JOIN BI_DWH_BC.D_ITEM IT ON IT.PK_ITEM = SM.FK_STMOV_ITEM
INNER JOIN BI_DWH_BC.D_SHOP S ON S.PK_SHOP = SM.FK_STMOV_SHOP
WHERE
D.DATE_FULLDATE <= CONVERT (date, GETDATE()-1)
GROUP BY
S.SHOP_CODE, IT.ITEM_CODE
HAVING
SUM(SM.STMOV_QTY) <> 0
) as stock ON allShopsItem.ShopCode = stock.ShopCode AND allShopsItem.ItemCode = stock.ItemCode
LEFT OUTER JOIN (
SELECT
S.SHOP_CODE as ShopCode,
PL.ITEMID as ItemID,
SUM(CAST(PL.REMAINPURCHPHYSICAL AS INTEGER)) as sumQTY
FROM
BI_STAGING.ERP_PURCHLINE PL
INNER JOIN BI_STAGING.ERP_PURCHTABLE PT ON PT.PURCHID = PL.PURCHID
LEFT OUTER JOIN BI_STAGING.ERP_VENDTABLECUBE V ON PT.INVOICEACCOUNT = V.ACCOUNTNUM
LEFT OUTER JOIN BI_DWH_BC.D_SHOP S ON S.SHOP_CODE = RIGHT(PT.INVENTLOCATIONID,3)
WHERE
PL.REMAINPURCHPHYSICAL <> 0 AND PL.QTYORDERED <> 0
GROUP BY
S.SHOP_CODE, PL.ITEMID
) as outstandingorders ON allShopsItem.ShopCode = outstandingorders.ShopCode AND allShopsItem.ItemCode = outstandingorders.ItemID
GROUP BY
allShopsItem.ShopCode, allShopsItem.ItemCode,allShopsItem.SupplyNumber, sales.SumQtyTransactions, stock.Qty, outstandingorders.sumQTY
ORDER BY
allShopsItem.ShopCode, allShopsItem.ItemCode
以下示例的输出可通过以下示例进行比较：
shopcode itemcode Sales Stock
-------- -------- ----- -----
0013 121212 2 1
0013 122224 3 2
0032 121545 1 1
0032 121211 2 5
现在我需要以下xml：
<shopcode>
<itemcode>
<sales>
</sales>
<stock>
</stock>
</itemcode>
<itemcode>
<sales>
</sales>
<stock>
</stock>
</itemcode>
</shopcode>
简而言之，我想要概述每个商店的所有商品。 有人在我的查询中进行一些调整后，是否知道如何以相对简单的方式做到这一点？
提前致谢！

我不确定您希望XML结构如何（例如，您是否需要将商店/商品代码作为属性？），但这样的内容可能对您有用..
SELECT
