CI3 error with query SQLSERVER

Hi I think CI has a problem when I use pivot function in sqlserver, I made another test usign the next query

PHP Code:

SELECT * FROM ( 
SELECT DAY(CC.FECHA) AS DIA,CC.DOMINIO,CC.INCALLS
FROM [dbo].[CCOD_INFORME_COLA_DIARIO_AUX] AS CC 
LEFT JOIN [dbo].[COLAS] AS C ON C.COLA = CC.COLA
WHERE CC.AÑO = 2021 AND MONTH(CC.FECHA) = 1 AND C.IDAREA = 1 
) X PIVOT ( SUM(INCALLS) FOR DIA IN ([4],[5])) P 


It´s simple but when I print the result in the controller only show me.

PHP Code:

(
    [0] => stdClass Object
        (
            [DOMINIO] => IT HELP DESK
        )

    [1] => stdClass Object
        (
            [DOMINIO] => PAYROLL
        )

) 


When If I run it in SQlServerStudio gave a table that I want

Code:

DOMINIO             4    5
IT HELP DESK    14    19
PAYROLL            484    437

Anyone could fix this or have an example?
