Clear Method (ADO)
Use the Clear method on the Errors collection to remove all existing Error objects from the collection. When an error occurs, ADO automatically clears the Errors collection and fills it with Error objects based on the new error.
Some properties and methods return warnings that appear as Error objects in the Errors collection but do not halt a program's execution. Before you call the Resync, UpdateBatch, or CancelBatch methods on a Recordset object; the Open method on a Connection object; or set the Filter property on a Recordset object, call the Clear method on the Errors collection. That way, you can read the Count property of the Errors collection to test for returned warnings.
