ConnectionBroken Event
未來的 Microsoft SQL Server 版本將移除這項功能。請避免在新的開發工作中使用這項功能,並規劃修改目前使用這項功能的應用程式。
The ConnectionBroken event occurs when a connected SQLServer object loses its connection to an instance of Microsoft SQL Server.

Parts
object
Expression that evaluates to an object in the Applies To list.Message
String that contains descriptive message text.
Prototype (C/C++)
HRESULT ConnectionBroken(SQLDMO_LPCSTR Message,
LPBOOL Retry);
備註
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.
