sqloptions:clientNetworkID 标头元素
后续版本的 Microsoft SQL Server 将删除该功能。 请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。
sqloptions:clientNetworkID 登录选项允许客户端指定用于登录的客户端网络 ID，例如：
<SOAP-ENV:Header
xmlns:SOAP-ENV="https://schemas.xmlsoap.org/soap/envelope/"
xmlns:sqloptions="https://schemas.microsoft.com/sqlserver/2004/SOAP/Options">
<sqloptions:clientNetworkID SOAP-ENV:mustUnderstand="1" value="networkID" />
</SOAP-ENV:Header>
sqloptions:clientNetworkID 登录选项显示为 SOAP 标头。它由一个名为 sqloptions:clientNetworkID 的元素组成。该元素有一个属性 (value)，它是一个 base64 编码的二进制值。它提供了可为登录设置的客户端网络 ID。它显示在 sys.sysprocesses 兼容视图的 net_address 列中。
一个请求中只能出现 sqloptions:clientNetworkID 选项的一个实例。此标头不能出现在响应中。多个选项实例将会生成错误。
服务器可能限制 sqloptions:clientNetworkID 值的可识别值的范围。如果客户端提交的值超出了允许的范围，则服务器将自行截断该值，截断方式不定。
如果使用 SOAP 会话，则必须在与 sqloptions:sqlsession initiate 属性相同的请求中显示此选项。如果在任何带有 sqloptions:sqlSession 标头但不包含 initiate 属性的请求中显示此选项，则将生成错误。
下面是 sqloptions:clientNetworkID 选项的架构片断：
<xs:element name="clientNetworkID" form="qualified">
<xs:annotation>
<xs:documentation>
Set the client network ID for the login.
</xs:documentation>
</xs:annotation>
<xs:complexType>
<xs:attribute
use="required"
name="value"
type="xs:base64Binary"
form="unqualified">
<xs:annotation>
<xs:documentation>
The client network ID to set for the login.
</xs:documentation>
</xs:annotation>
</xs:attribute>
</xs:complexType>
</xs:element>
