Prototype (C/C++)
HRESULT GetStandbyFiles(SQLDMO_LPBSTR pRetVal);
HRESULT SetStandbyFiles(SQLDMO_LPCSTR NewValue);

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
Database log restoration with undo is available against a read-only image of a SQL Server database and offers one strategy for maintaining a standby image of a critical instance.
