ConnectionBroken Event

后续版本的 Microsoft SQL Server 将删除该功能。 请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。

The ConnectionBroken event occurs when a connected SQLServer object loses its connection to an instance of Microsoft SQL Server.

语法

Private Functionobject_ConnectionBroken(Message as String)asBoolean

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);

注释

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.

Applies To:

SQLServer Object
