Question

I have two problematic columns: Fee NUMBER type, AdjFee also NUMBER.

After

column Fee format a5;
select Fee ID smth
from Visit;
<         


        

Answer 1

Yes, column names can be truncated (or) changed to the name you want

From your above select statement.

If you want to truncate 'Fee' column to 'Fe'. Here is the procedure -

col c1 heading "Fe" for a5

col c2 heading "ID" for 999

col c3 heading "smth" for a5

select fee c1, ID c2, smth c3 from visit;
