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.

备注

Members of the sysadmin fixed server role or the db_owner fixed database role can set the UserName property to impersonate the specified database user. For more information, see SETUSER (Transact-SQL).
