Dear Friends,

I need one urgent clarification regarding the ROWID in Oracle 8i & 9i. Yesterday we have migrated our application database from 8i to 9i and we are facing some data sorting issues. Is there any difference between 8i & 9i in terms of rowid ?

Almost in all the master tables, after migration the displaying order of the data is changed. In some of the LOV's we have not specified the sorting order and hence the sorting order will be based on ROWID.

The 8i display order is (As per the rows inserted order)

code    description
--------------------
AAA    AAAAAAAAAAA
BBB     BBBBBBBBBBBB
YYY     YYYYYYYYYY

In the 9i database after migration

Code   description
----------------------
YYY     YYYYYYYYYY
AAA    AAAAAAAAAAA
BBB     BBBBBBBBBBBB

What could be the reason for that? Advanced thanks for your solutions.

Thanks & Regards,
B.Prasad

>>> hence the sorting order will be based on ROWID.

Oracle doesnt return rows in any predifined order ,unless you explicitly sort them by a column.
Ordering by ROWIDS may not give you consistent result.
It is all becuase ROWID's may be reused.
