HRESULT GetMediaDescription(SQLDMO_LPBSTR pRetVal);
HRESULT SetMediaDescription(SQLDMO_LPCSTR NewValue);

注意
SQL Distributed Management Objects (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.
