Figure 17-3. The ADO object model
There are potentially four ways in which to determine whether a particular feature is
supported by a particular data provider:
Check the documentation for the data provider (if you can find it).
•
Use the
Supports
method of the
Recordset
object to determine whether certain
features are supported (but this only applies to the
Recordset
object).
•
Use dynamic properties, discussed later.
•
Experiment. If you get the error message shown in Figure 17-4, then you know
that the operation that caused the message is not supported!
•

Note that we will discuss most of the properties and methods in the ADO object model,
with the primary exception of those that relate to batch processing or transaction
processing.
