Question

select *
from ss.mailer_data
where
id = 249122
and address_3 like'%%'

will not hit on address_3. I’ve tried changing the last line to

and address_3 is null

and address_3 = ''

and address_3 = ' '

I tried using char_length, ascii functions and they return nothing for that filed value. Anyone have any ideas?

Answer 1

could also be that id = 249122 is not true for that combination. What happens when you do

select *
from ss.mailer_data
where address_3 is null

or

select *
from ss.mailer_data
where address_3 = ''
