I need to Validate Column Names(check to see if the columns are the same or spelt the same in both tables) in 2 Identical ORACLE tables. Can someone help me with that. I am trying to use ALL_TAB_COLUMNS data dictionary view.
Any help will be appreciated.

the following table should return no rows...
(select table_name, column_name, data_type, data_length, data_precision, nullable
from all_tab_columns
where table_name = 'T1'
and owner = 'SCOTT'
MINUS
select table_name, column_name, data_type, data_length, data_precision, nullable
from all_tab_columns
where table_name = 'T2'
and owner = 'SCOTT')
UNION
(select table_name, column_name, data_type, data_length, data_precision, nullable
from all_tab_columns
where table_name = 'T2'
and owner = 'SCOTT'
MINUS
select table_name, column_name, data_type, data_length, data_precision, nullable
from all_tab_columns
where table_name = 'T1'
and owner = 'SCOTT');
