sqloptions:environmentChangeNotifications Header Element

The sqloptions:environmentChangeNotifications SOAP header enables the client to specify which environment change notifications the client wishes to receive, for example:

<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>

The sqloptions:environmentChangeNotifications option appears as a SOAP header. The header is made up of one element, named sqloptions:environmentChangeNotifications. The element has four optional attributes: databaseChange, languageChange, partnerChange, and transactionBoundary; each of which is a Boolean value. The default value for all four is false. The optional attributes specify which notifications the client wants to receive.

Only one instance of the sqloptions:environmentChangeNotifications option can appear in a request. The option cannot appear in a response. Multiple instances of the option will generate an error, as will the existence of any content within the sqloptions:environmentChangeNotifications node.

If SOAP sessions are being used, this option must appear in the same request as the sqloptions:sqlsession initiate attribute. If this option appears in any request with a sqloptions:sqlSession header that does not also contain the initiate attribute, an error is generated.

The following is a schema fragment for the sqloptions:environmentChangeNotifications option:.
