sqloptions:initialLanguage 标头元素
sqloptions:initialLanguage SOAP 标头使客户端可以指定要设置的初始语言，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:initialLanguage
SOAP-ENV:mustUnderstand="1"
value="name of initial language to use"
optional="true" | "false" />
</SOAP-ENV:Header>
sqloptions:initialLanguage 选项就是一个 SOAP 标头。该标头由一个名为 sqloptions:initialLanguage 的元素组成。该元素具有一个必需的属性 value。这是一个字符串值。value 属性指定要设置的初始语言的名称。解释该字符串的方式与解释 SET LANGUAGE Transact-SQL 语句的方式相同。此元素有一个可选属性 optional。这是一个布尔值（默认值为 false）。可选属性指定无法连接到数据库时登录是否会失败：false 表示登录应失败，true 表示登录可以继续。
一个请求中只能出现 sqloptions:initialLanguage 选项的一个实例。该选项无法在响应中出现。多个选项实例将会生成错误。
如果使用 SOAP 会话，则此选项必须出现在与 sqloptions:sqlsession initiate 属性相同的请求中。如果在任何带有 sqloptions:sqlSession 标头但不包含 initiate 属性的请求中出现此选项，则将生成错误。
下面是 sqloptions:initialLanguage 选项的架构片段：
<xs:element name="initialLanguage" form="qualified">
<xs:annotation>
<xs:documentation>
Set initial language to set.
</xs:documentation>
</xs:annotation>
<xs:complexType>
<xs:attribute use="required" name="value" type="xs:string" form="unqualified">
<xs:annotation>
<xs:documentation>
The name of the initial language to set.
</xs:documentation>
</xs:annotation>
</xs:attribute>
<xs:attribute
name="optional"
default="false"
type="xs:boolean"
form="unqualified">
<xs:annotation>
<xs:documentation>
Whether the initial language is optional or not.
</xs:documentation>
</xs:annotation>
</xs:attribute>
</xs:complexType>
</xs:element>
