| 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
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.
