If you take a look at the first paragraph of the PI OLEDB Enterprise 2016 Release Notes, you will find;
"PI OLEDB Enterprise is an OLE DB data provider which provides access to the PI System in a relational view, accessible through SQL queries. The provider supports read-only access to asset and event data stored in the PI Asset Framework (AF), such as AF Elements, AF Attributes, and PI Event Frames...."
Therefore, as PI OLEDB Enterprise is still read-only, I suggest you to use PI Web API or PI AF SDK instead in order to update an attribute.
Hope this helps!
