SQL Server 2014查詢更新插入XML節點成功但未插入節點

Question

我正在嘗試完成家庭作業分配以創建，插入，修改和查詢XML表。到目前爲止，我已經能夠創建表格並插入一些數據行;但是，我卡在修改後的部分。我創建了查詢併成功執行，但未插入新的材料節點。我必須在所有功能節點下插入此子節點。

CREATE TABLE Prod_Catalog 
(
ID int NOT NULL Primary Key, 
xCol xml NOT NULL, 
) 

-

INSERT INTO dbo.Prod_Catalog VALUES 
(1,'<root><productdescription ProductID="P5500xs" ProductName="Brava 55 TV"> 
     <features>Features 
      <warranty>5 years</warranty> 
      <maintenance>Dont hit with hammer</maintenance> 
     </features></productdescription> 
    </root>'), 
(2,'<root><productdescription ProductID="G29-2" ProductName="Panasonic 1100Watt Microwave"> 
     <features>Features 
      <warranty>1 year</warranty> 
      <maintenance>Dont cook metal forks!</maintenance> 
     </features></productdescription> 
    </root>'), 
(3,'<root><productdescription ProductID="LG22-XL" ProductName="LG 20 cubic refrigerator"> 
     <features>Features 
      <warranty>1 year</warranty> 
      <maintenance>Makes things cold.</maintenance> 
     </features></productdescription> 
    </root>') 

-

UPDATE dbo.Prod_Catalog 
SET xCol.modify('insert <materials>Electronics,Glass,Flashy Lights</materials> as first into (/root/productiondescription[@ProductID=("P5500xs")]/features)[1]'); 
GO

productiondescription不是元素名稱。產品描述是。 - Damien_The_Unbeliever 11小時以前
