that works unless there is also a reason to see insert not just in order but by
"inserted on a particular date or time". I suppose in that case, add two fields,
a date field for the time range and a numeric field for the sequence of insert

using a date will work unless you get multiple records created in a given
second. Use a sequence generated number. The larger the number, the newer
the record. Just order by the sequence to see the order the records were
inserted.

Do you want to physically order them or do you just want to know by time the
order in which they were entered.
if the first, no, not that I know of. If the later, yes, add another column
(ins_date date) and a trigger to populate that column with sysdate when you
insert a row. You can then order by ins_date

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.
