Implementation Details By Method

The Advantage OLE DB Provider supports IViewChapter interface member functions as described in the following table.

Member Function	Description
GetSpecification	Returns the rowset from which the view was created.
OpenViewChapter	Returns a chapter that can be passed to rowset methods that accept HCHAPTER handles. A chapter is an opaque object that contains the necessary filter information to be used by the rowset methods.

The Advantage OLE DB Provider supports IViewFilter interface member functions as described in the following table.

Member Function	Description
GetFilter	Returns E_NOTIMPL.
GetFilterBindings	Returns E_NOTIMPL.
SetFilter	Specifies a filter condition for a view. Note that the accessor handle must be created on the rowset from which the view was created. View objects in the Advantage OLE DB Provider do not support the IAccessor interface. Note that the Advantage OLE DB Provider does not support filtering on memo, raw, or BLOB fields. If the accessor references fields of these types, this method returns DB_E_CANTFILTER.

The Advantage OLE DB Provider supports ISupportErrorInfo interface member functions as described in the following table.

Member Function	Description
InterfaceSupportsErrorInfo	Indicates whether a specific OLE DB interface can return OLE DB error objects.
