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

I think you're looking for the concat function here.

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