Danny,
What people trying to tell you is that you probably need this -

update lincbase.genrawdata set fuel_fill_dt2 =

to_date(substr(fuelfilldate,-8,2) || '/' ||
substr(to_char(fuelfilldate),-6,2) || '/' ||
substr(to_char(fuelfilldate),-4),'mm/dd/yyyy')

where fuel_fill_dt2 is null and length(to_char(fuelfilldate)) = 8;
