CDaoQueryDef::CanUpdate
Call this member function to determine whether you can modify the querydef — such as changing its name or SQL string.
BOOL CanUpdate( );
Возвращаемое значение
Nonzero if you are permitted to modify the querydef; otherwise 0.
Заметки
You can modify the querydef if:
It is not based on a database that is open read-only.
You have update permissions for the database.
This depends on whether you have implemented security features. MFC does not provide support for security; you must implement it yourself by calling DAO directly or by using Microsoft Access. See the topic "Permissions Property" in DAO Help.
