sqloptions:environmentChangeNotifications 헤더 요소
sqloptions:environmentChangeNotifications SOAP 헤더를 사용하면 클라이언트가 받을 환경 변경 알림을 지정할 수 있습니다. 예를 들면 다음과 같습니다.
<SOAP-ENV:Header
xmlns:SOAP-ENV="https://schemas.xmlsoap.org/soap/envelope/"
xmlns:sqloptions="https://schemas.microsoft.com/sqlserver/2004/SOAP/Options">
<sqloptions:environmentChangeNotifications
SOAP-ENV:mustUnderstand="1"
databaseChange="true" | "false"
languageChange="true" | "false"
transactionBoundary="true" | "false" />
</SOAP-ENV:Header>
sqloptions:environmentChangeNotifications 옵션은 SOAP 헤더로 나타납니다. 이 헤더는 sqloptions:environmentChangeNotifications라는 하나의 요소로 구성됩니다. 이 요소에는 databaseChange, languageChange, partnerChange 및 transactionBoundary의 4가지 선택적 특성이 있습니다. 각 특성은 부울 값입니다. 이러한 4가지 선택적 특성의 기본값은 모두 false입니다. 선택적 특성은 클라이언트가 받을 알림을 지정합니다.
sqloptions:environmentChangeNotifications 옵션은 한 요청에서 한 번만 나타날 수 있습니다. 이 옵션은 응답에는 나타날 수 없습니다. 이 옵션이 여러 개 나타나면 오류가 발생합니다. sqloptions:environmentChangeNotifications 노드 내에 내용이 있어도 오류가 발생합니다.
SOAP 세션을 사용하고 있는 경우 이 옵션은 sqloptions:sqlsession initiate 특성과 같은 요청에 나타나야 합니다. sqloptions:sqlSession 헤더가 있으며 initiate 특성이 포함되지 않은 요청에 이 옵션이 나타나면 오류가 발생합니다.
