I suppose so. Quite difficult for the last-used info to get updated for an object that no longer exists :-) Hardly seems a /resolution/ however:

<sarcasm> Damned optimizer choosing to implement with /the wrong/ keyed access path. Nothing like a good use of [an effective] DROP INDEX to /teach a lesson/ to that query optimizer ;-) The optimizer should stop finding that AccPth and start creating plans to find the data [rows to be changed] using a less-optimal\efficient path! </sarcasm>
