Hi everybody:

Now I have an issue with the create_table_cost procedure. I have executed
it for a table and got the following results (oracle 10.2.0.3)

used - 11141112
allocated - 1114112

That seem to indicate that there is no space wasted associates with this
table

But when I queried dba_segments  select sum(bytes/1024)/1024 from
dba_segments where segment_name =  and owner =
I got 2785280 - or more than twice the size that I received from
create_table_cost. What is the reason for this discrepancy?

thank you

Gene Gurevich
