IPersist* Objects

COM objects can be stored in columns in a rowset. Such objects are required to expose IPersistStream, IPersistStreamInit, or IPersistStorage. The rowset has to know how to create instances of these objects, so it must store the objects' class IDs. How this is done is provider-specific.

This section contains the following topics:

• Getting and Setting IPersist* Objects
