Symptom
-
Extra table scan operator on update target table exists in 'set showplan on' output
- The query joins two tables; update target table name qualified as dbo.tablename, but table name in "from clause" does not include owner name dbo.
- Only regular users (non-DBO / non-SA) get into this problem. DBO or SA gets expected query plan.
- The update query may produce wrong results due to invalid query plan.
