使用TSQL选择XML节点

Question

我的SQL Server 2008数据库表有一个XML字段.我想从字段中选择节点以及其他字段.例如,请考虑下表:

DECLARE @TestTable AS TABLE ([Id] VARCHAR(20),  [Name] XML )
INSERT INTO @TestTable SELECT 
    '001', 
    '<Name><First>Ross</First><Last>Geller</Last></Name>'
UNION ALL SELECT
    '002', 
    '<Name><First>Rachel</First><Last>Green</Last></Name>'

我希望结果是:

001  |  Ross  |  Geller     
002  | Rachel | Green

那可能吗？谢谢,

这应该这样做:

DECLARE @TestTable AS TABLE (
     [Id] VARCHAR(20),
     [Name] XML
    )
INSERT  INTO @TestTable
        SELECT  '001',
                '<Name><First>Ross</First><Last>Geller</Last></Name>'
        UNION ALL
        SELECT  '002',
                '<Name><First>Rachel</First><Last>Green</Last></Name>'

SELECT  Id,
        x.value('(/Name/First)[1]', 'varchar(20)') AS [First],
        x.value('(/Name/Last)[1]', 'varchar(20)') AS [Last]
FROM    @TestTable t
CROSS APPLY [Name].nodes('/Name') AS tbl ( x )
