Note Although the Supports method may return True for a given functionality, it does not guarantee that the provider can make the feature available under all circumstances. The Supports method simply returns whether or not the provider can support the specified functionality assuming certain conditions are met. For example, the Supports method may indicate that a Recordset object supports updates even though the cursor is based on a multi-table join, some of the columns of which are not updatable.
