Case when a value is different to other value, SQL Server

Question

I have this table structure for table prices:

CREATE TABLE prices
(
     id int, 
     priceFrom int, 
     priceUp int
);

INSERT INTO prices (id,          


        

Answer 1

You have to CAST to VARCHAR:

select pricefrom, priceup,
       case
          when pricefrom = 0 then null
          when priceFrom <> priceUp then concat(cast(priceFrom as varchar(8)),
                                                ' - ', 
                                                cast(priceUp as varchar(8)))
          when priceFrom = priceUp then cast(priceFrom as varchar(8))
       end as FinalPrice
from prices
