SQL Server XML数据导入

在将xml日期字段导入sql server时遇到问题，其他字段也可以。我尝试了很多方法，但它总是返回空值。需要帮忙吗

2014-02-18T12:15:21.357是问题所在

XML是

<?xml version="1.0" encoding="utf-8"?>
<MISRoot xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/IGUK.Evolution.FieldToolLite.Lib.MIS">
    <Claims>
        <Claim>
            <Amalgamation>
                <ChannelSolutions /> 
                <Name i:nil="true" /> 
            </Amalgamation>
            <Appointments>
                <Appointment>
                    <Access /> 
                    <AccessGranted>true</AccessGranted> 
                    <AppointmentId>320</AppointmentId> 
                    <EnterTime>2014-02-18T12:15:21.357</EnterTime> 
                    <LeaveTime i:nil="true" /> 
                    <Name i:nil="true" /> 
                </Appointment>
            </Appointments>
            <CustomProducts /> 
            <Id>1220</Id> 
            <Payments /> 
            <Tasks /> 
        </Claim>
    </Claims>
</MISRoot>

有问题，我已将您的文件复制到

XML

变量中，并能够使用以下查询进行检索

DECLARE @MyXMLVariable XML = 
'<?xml version="1.0" encoding="utf-8"?>

        </Amalgamation>
        <Appointments>
            <Appointment>
                <Access /> 
                <AccessGranted>true</AccessGranted> 
                <AppointmentId>320</AppointmentId>
