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. |
備註
The ExpirationDate property is valid only for backup data stored on disk or tape devices. Backup sets older than the expiration date can be overwritten by a later backup.
