Question

我正在尝试完成一项家庭作业，以创建，插入，修改和xquery XML表。到目前为止，我已经能够创建表并插入一些数据行;但是，我被困在修改过的部分。我已创建查询并成功执行，但未插入新的材料节点。我必须在所有功能节点下插入此子节点。

    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
