ConnectionBroken Event
Questa caratteristica verrà rimossa a partire da una delle prossime versioni di Microsoft SQL Server. Evitare di utilizzare questa funzionalità in un nuovo progetto di sviluppo e prevedere interventi di modifica nelle applicazioni in cui è attualmente implementata.
The ConnectionBroken event occurs when a connected SQLServer object loses its connection to an instance of Microsoft SQL Server.
Sintassi

Prototype (C/C++)
HRESULT ConnectionBroken(SQLDMO_LPCSTR Message,
LPBOOL Retry);
Osservazioni
SQL Distributed Management Objects (SQL-DMO) raises the ConnectionBroken event only when the AutoReConnect property of the SQLServer object is False. When AutoReConnect is True, SQL-DMO will not raise the event, even when automatic reconnection fails.
When a ConnectionBroken event handler returns True, SQL-DMO attempts to reconnect to an instance of SQL Server indicated when the Connect method of the SQLServer object connected successfully. When a ConnectionBroken event handler does not return a value, or returns False, SQL-DMO does not attempt to reconnect the SQLServer object upon return from the event handler.
