Re: SELECT Output Default Ordering ?

It depends on the access path and any other implicit sorting.

Access path - on a full table scan, the data is returned in the physical order it is stored in the object. An index scan will return the data sorted according to the rule of the index.
Implicit sorting - distinct will cause an implicit sort, as will group by.
