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. |
注释
Setting DatabaseFiles directs backup or restore processing to include only those operating system files listed. To specify an operating system file, use its logical name as visible to Microsoft SQL Server, not its physical or operating system name.
Set DatabaseFiles to an empty string to reset processing and target the entire database.
