2619053 - Getting wrong result on UPDATE by regular user when target table name includes owner name dbo.tablename -- SAP ASE

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.
