我有一個XML文件，我將其分解爲SQL Server 2008中的一個表。它深入幾個節點，這是我第一次嘗試這樣做，所以我確信我在某處錯過了這一點。將XML分解爲SQL Server 2008會創建重複的信息
我得到它的工作，但對於97條記錄的XML我得到每個記錄97次，即在結果集中總共9409行！這大概需要37秒。如果我使用SELECT DISTINCT我得到97行，但它（可預測）也需要37秒。該XML的

我可以表現生活（這將是持續的進口和XML文件可以是6-7倍比這更大），因爲我可以提取正確的結果集。但我真的很想知道如何做到這一點！我剛剛在這裏閱讀（http://stackoverflow.com/questions/61233/the-best-way-to-shred-xml-data-into-sql-server-database-columns）添加架構將有助於巨大的表現，我會在明天嘗試。多行對我來說是令人困惑的問題。
很多感謝:)
