Re: Oracle Hash

Just a few points:

What if my block size isn't 8K?
You do know that underscore is a single character wildcard in Oracle?
Why limit your self to tables with a name starting with "PS"?
Why not use DBI? Say I want to run this script on something other than Windows?
Why select all of the tables when the script only prints out the value for a single table?
Why build two hashes when a single one will do? (specifically $TabNam{$tabnam} = $tabname; is completely redundant)
use warnings?
use strict?

Would this be better written as an SQL script or stored procedure? After all, it's just:

select round(bytes/1048576,2)
from user_segments
where segment_name = upper('&1');

The script prints out the size of each table in block, but what if I have 200 tables? 300? Given the description of the script, was this intended behaviour?
Your output is to any number of decimal place, surely a sprintf would be beneficial?
