to_number question 2004-07-14 - By Stephen.Lee@(protected)
OK. It 's something about the WHERE clause being outside the subquery.
(Mebbe somebody can explain it.)
select nbr_cc_fop_name from nbr_cc
where nbr_cc_fop_name in ( 'AX ', 'MC ', 'VI ', 'DS ')
and to_number(trim(nbr_cc_no_high)) - to_number(trim(nbr_cc_no_low)) > 0
WORKS!
