If you want the data returned in an order, you can create an index with the order you want, and in your query provide a hint for Oracle to use that index. If your query is such that Oracle actually uses that index, the data will be returned in that order. I work with a large application that entirely depends on this principle. Crude but nevertheless effective.

When NOT Giving any Order by Clause , How is the Output of the SELECT Clause ordered by Default ?
Assuming There exists a Unique index on the Table

Is some Rule followed ?

NOTE Records may have been INSERTED into the Table in some manner differing from the Order of the data of the Unique index Key fields.

Thanks
