ExpirationDate Property

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 ExpirationDate property specifies the last valid date for the backup data.

语法

object
.ExpirationDate [=value]

Parts

• object
  An expression that evaluates to an object in the Applies To list.

• value
  A string that specifies a date.

Data Type

String

Modifiable

Read/write

Prototype (C/C++)

HRESULT GetExpirationDate(SQLDMO_LPBSTR pRetVal);
HRESULT SetExpirationDate(SQLDMO_LPCSTR NewValue);

注意：
SQL Distributed Management Objects (SQL-DMO) strings are always returned as OLE BSTR objects. A C/C++ application obtains a reference to the string. The application must release the reference using SysFreeString.

备注

The ExpirationDate property is valid only for backup data stored on disk or tape devices. Backup sets older than the expiration date can be overwritten by a later backup.
