RetainDays Property
未來的 Microsoft SQL Server 發行版本將不再提供此功能。請避免在新的開發工作中使用此功能，並計劃修改目前使用此功能的應用程式。
The RetainDays property specifies the number of days that must elapse before a backup set can be overwritten.
語法
object
.RetainDays [= value]
Parts
- object
An expression that evaluates to an object in the Applies To list
- value
A long integer that specifies a number of days
Data Type
Long
Modifiable
Read/write
Prototype (C/C++)
HRESULT GetRetainDays(LPLONG pRetVal);
HRESULT SetRetainDays(long NewValue);
備註
For Microsoft SQL Server, backup set retention period is set when media is initialized. If SQL Distributed Management Objects (SQL-DMO) is used to automate SQL Server backup, the RetainDays property is only evaluated if the Initialize property is TRUE.
