Question

I am trying to access a field from a table and give different output based on the field content.
If the field has 0 I want to fetch No else if 1 or NULL I want to fetch yes.
It is working well for 0 or 1 but not for NULL.

Select  distinct(convert(varchar(255),( CASE Field1
                                         WHEN 0 
                                             THEN 'No'
                                         WHEN 1
                                             THEN 'Yes'
                                         WHEN NULL 
                                             THEN 'Yes' 
                                       END ))) AS Field1 FROM Table1

Answer 1

CASE Field1
WHEN 0 THEN 'No'              
ELSE 'Yes'
END

or this:

CASE ISNULL(Field1, 1)
WHEN 0 THEN 'No'              
WHEN 1 THEN 'Yes'
END
