| hi all,
|
| can any body tell me,
| in which order oracle scans the rows in a table in normal select
| quries?

In any order it wants.
It depends on Oracle version, structure (partition, index...), query, parallelism...
Btw, there is neither top nor bottom of a table.
Why do you want to know that?
