CONCAT will work with strings/varchar, but not with numbers. So if primerNombre and segundNombre are INT data types, CONCAT will fail. Try using the CONVERT function:

SELECT DISTINCT nIdentidad, 
       CONCAT( CONVERT(primerNombre, char(8)), ' ', 
               CONVERT(segundoNombre, char(8))  ) as nombre
