ExpirationDate Property
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 ExpirationDate property specifies the last valid date for the backup data.
語法
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);
[!附註]
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.
備註
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.
