Question

Based on the SELECT CASE below I want to show two separate columns within one WHEN. Is this possible?

The two commented out lines below are something like what I would like to have. I am sure it is something very simple I am missing. As it is, there is a syntax error.

select 
    person.FirstName,
    person.LastName,
    CASE 
        --WHEN substatus is not null then 'HasSubstatus', null
        --else null, 'DoesNotHaveSubstatus'
        WHEN substatus is not null then 'HasSubstatus'
        else null
    end
from Person person

Answer 1

You cannot do it in a single Case expressions as a Case expression returns a single value. You must use two Case expressions.

Select  person.FirstName
    , person.LastName
    , Case When substatus is not null Then 'HasSubstatus' End As [HasSubstatus]
    , Case When substatus is null Then 'DoesNotHaveSubstatus' End As [DoesNotHaveSubstatus]
From Person person
