假设您的表名为YourTable，XML列名为XmlData，请根据您的实际情况进行调整和更改！，您可以尝试以下XQuery代码：

-- declare the XML namespace as the DEFAULT
;WITH XMLNAMESPACES(DEFAULT 'bb_appfx_dataforms')
    SELECT
        -- extract the value from the <Value> subnode of the <fv> node, if found
        FvValue = XC.value('(Value)[1]', 'varchar(200)')
    FROM
        dbo.YourTable
    CROSS APPLY
        -- get a list of XML fragments - one for each <fv> node
        XmlData.nodes('/DataFormItem/Values/fv') AS XT(XC)
    WHERE
        -- find the XML fragment with the ID="Description"
        XC.value('@ID', 'varchar(50)') = 'Description'
