to_number question 2004-07-14 - By Stephen.Lee@(protected)
Well now I 'm not so sure about the previous post I did. Observe!
(The reason for the subquery is that I have been screwing around with what
was in it.)
select distinct nbr_cc_fop_name, X, Y
from (
select nbr_cc_fop_name, to_number(trim(nbr_cc_no_high)) X ,
to_number(trim(nbr_cc_no_low)) Y
from nbr_cc
where nbr_cc_fop_name in ( 'AX ', 'MC ', 'VI ', 'DS ')
)
NBR_CC X Y
-- --- -- ---- ---- ------ -- ---- ---- ------

======= AND NOW =======
select distinct nbr_cc_fop_name, X, Y
from (

to_number(trim(nbr_cc_no_low)) Y
from nbr_cc
where nbr_cc_fop_name in ( 'AX ', 'MC ', 'VI ', 'DS ')
)
where X - Y > 0 < <-- -- SCREWS IT UP
