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
------ ------------------- -------------------
AX         349999999999999     340000000000000
AX         379999999999999     370000000000000
DS        6011999999999999    6011000000000000
MC        5590999999999999    5000000000000000
MC        5999999999999999    5592000000000000
VI           4999999999999       4000000000000
VI        4999999999999999    4000000000000000

AND NOW =======

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')
)

where X - Y > 0 <<----- SCREWS IT UP

select nbr_cc_fop_name, to_number(trim(nbr_cc_no_high)) X , to_number(trim(nbr_cc_no_low)) Y
