DatabaseFileGroups Property
Questa caratteristica verrà rimossa a partire da una delle prossime versioni di Microsoft SQL Server. Evitare di utilizzare questa funzionalità in un nuovo progetto di sviluppo e prevedere interventi di modifica nelle applicazioni in cui è attualmente implementata.
The DatabaseFileGroups property identifies filegroups targeted by a backup or restore operation.
Sintassi
object.DatabaseFileGroups [=value]
Parts
object
An expression that evaluates to an object in the Applies To listvalue
A SQL Distributed Management Objects (SQL-DMO) multistring identifying one or more filegroups by name
Data Type
String
Modifiable
Read/write
Prototype (C/C++)
HRESULT GetDatabaseFileGroups(SQLDMO_LPBSTR pRetVal);
HRESULT SetDatabaseFileGroups(SQLDMO_LPCSTR NewValue);
[!NOTA]
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.
Osservazioni
Setting DatabaseFileGroups directs backup or restore processing to include only those filegroups listed.
Set DatabaseFileGroups to an empty string to reset processing and target the entire database.
