When I add a "Dest_carrier" VARCHAR(3) field to a "destinations" table, that field contains nothing. As I gradually fill in values and want to display only the records in which that field is not yet filled in
> how do I spell the SQL statement < ?
Select * from destinations
where Dest_carrier = NULL doesn't do the trick
where Dest_Carrier = ''
where len(trim(Dest_Carrier)) = 0
