can i use order by clause while selecting the rowid.
because largle table (example 200,000 records).the rowid is different .in oracle 7.3.

at the same time i am selecting max(rowid) it is giving some other rowid.

Hi,
Can you tell me why you want the data to be ordered by rowid? the rowid allocated will not be in the same sequence as data inserted. they ususally take up the next available rowid.
So, you might have to order by the data in the table and not by rowid to acheive the order you want.

To answer your question, yes you can order by rowid and it will still work in Oracle 8i.
As Kavitha asks though - why would you want to. Rowid is not garanteed to follow the order in which the rows were inserted into different blocks in the table extents.
