Hi All

Is there any method in Oracle to capture or order the rows in a table in the order they were entered.
I tried it with rowid but when a row is deleted, the rowid corresponding to this row is reassigned for a new row
which is inserted into the table at a later stage.

Eg.

SQL> select rowid,abc.* from abc order by rowid;

ROWID                       A
------------------ ----------
AAAFmYAASAAAYsqAAA        100
AAAFmYAASAAAYsqAAB        200
AAAFmYAASAAAYsqAAC        300

I deleted one transaction.

delete from abc where a=200;
commit;

Then I inserted two rows.

insert into abc values(500);
insert into abc values(600);
commit;

Now when I order by rowid

SQL> select rowid,abc.* from abc order by rowid;

ROWID                       A
------------------ ----------
AAAFmYAASAAAYsqAAA        100
AAAFmYAASAAAYsqAAB        600
AAAFmYAASAAAYsqAAC        300
AAAFmYAASAAAYsqAAD        500

I.e The values I entered last appeared second.The rowid (AAAFmYAASAAAYsqAAB ) corresponding to the row I deleted was reassigned for the last entered row (a=600).
What I want is that this must be sorted in the order of its entry. Can anyone help me out.
Thanks in advance
Systems.
