我試圖在使用FOR XML AUTO返回時，在我的SQL結果中理解一些異常。奇怪的是，我在XML中得到了不同的結果。總之，機構計數應該永遠是603，但XML數據讓我在這套片斷顯示3次不同的總計： 
與正常的行集相比，FOR XML AUTO子句可以提供意外的結果嗎？
的ORDER BY下面簡單地通過選擇訂購的結果。爲了進行調試，我手動運行了存儲過程（註釋掉FOR XML子句並創建了3個後綴爲SORT參數後綴的「調試」表（當沒有使用FOR XML AUTO時，每個結果集包含603行）。 。
希望，現已清楚地示出的問題這裏是存儲過程（底部邏輯其中@Sort值確定ORDER BY是最相關的我認爲）：
ALTER Procedure [dbo].[FLAS2_List_Awards_V4]
-- EXECUTE FLAS2_List_Awards_V4 2,0
(
@Sort int = 1
-- 1 = descending order on TotalAmount
-- 2 = descending order on TotalAwards
-- 3 = ascending order on Institution
,@Range int = 0
-- 0 = no filtering
-- 1 = < $1 million
-- 2 = < $5 million
-- 3 = < $10 million
-- 4 = < $15 million
-- 5 = < $20 million
-- 6 = > $20 million

順便提及，每個無論在使用INTO子句創建期間的順序如何，「DEBUG」表都有1117行。
