sqloptions:applicationName 标头元素
sqloptions:applicationName 登录选项使客户端可以指定用于登录的应用程序名称,例如:
<SOAP-ENV:Header
xmlns:SOAP-ENV="https://schemas.xmlsoap.org/soap/envelope/"
xmlns:sqloptions="https://schemas.microsoft.com/sqlserver/2004/SOAP/Options">
<SOAP-ENV:Header>
<sqloptions:applicationName SOAP-ENV:mustUnderstand="1" value="application name" />
</SOAP-ENV:Header>
<SOAP-ENV:Body>
</SOAP-ENV:Body>
</SOAP-ENV:Header>
sqloptions:applicationName
登录选项就是 SOAP 标头。它由一个名为 sqloptions:applicationName
的元素组成。该元素具有一个必需的属性 value
。此属性是一个字符串。value
属性指定要为登录设置的“应用程序名称**”。此名称将显示在 sys.sysprocesses 兼容性视图的 program_name 列中。
一个 SOAP 请求中只能出现一个 sqloptions:applicationName 可选标头实例。此标头不能显示在 SOAP 响应中。多个选项实例将会生成错误。
服务器可能会限制 sqloptions:applicationName 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。
如果正在使用 SOAP 会话,则此选项必须出现在用于启动 SOAP 会话的同一请求中。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。
以下是 sqloptions:applicationName
选项的架构片断:
<xs:element name="applicationName" form="qualified">
<xs:annotation>
<xs:documentation>
Set the application name for the login.
</xs:documentation>
</xs:annotation>
<xs:complexType>
<xs:attribute use="required" name="value" type="xs:string" form="unqualified">
<xs:annotation>
<xs:documentation>
The application name to set for the login.
</xs:documentation>
</xs:annotation>
</xs:attribute>
</xs:complexType>
</xs:element>
示例
以下是在 SOAP 请求和响应消息中使用 sqloptions:applicationName
标头的示例。
