Also, how about v$open_cursor or v$object_dependency or v$db_object_cache, and ultimately x$kglob or its cursor "subsection" x$kglcursor? If the SQL is a pseudo SQL like table_x_x_x_x_x (where x is a number) representing a cursor accessing a LOB column or object, it won't be in any v$sql% views, but will be in the other views. Not all other views use sql_id's yet; you need the hash value.
