How to create a table in a week and divide by day and hour

enter image description here

I can get courses for this request:

$qb
    ->select("c")
    ->from("ATLReservationBundle:Course", "c")
    ->where("WEEK(c.courseDate, 1) = WEEK(CURRENT_DATE(), 1)")
    ->orderBy("c.courseDate", "ASC");

But I want to group this data, for example:

DAY - 31
    HOUR - 12:15 > Coursename
    HOUR - 19:30 > Coursename
DAY - 01
    HOUR - 10:00...

I don't know how to do this, anyone?

UPDATE

New request:

   $qb
        ->select("c, HOUR(c.courseDate) as hour, DAY(c.courseDate) as day")
        ->from("ATLReservationBundle:Course", "c")
        ->where("WEEK(c.courseDate, 1) = WEEK(CURRENT_DATE(), 1)")
        ->orderBy("c.courseDate", "ASC")
        ->groupBy("hour, day");

But; There is a problem with this query, I could not group by HOUR(c.courseDate), DAY(c.courseDate)because I received this error:

Error: cannot be grouped by identifier or result variable undefined.

So, I defined the hour and day as a variable in the selection area. I do not want to see day and hour as different variables.

select hour(date), -- group by hour
case when weekday(date)=0 then course_name else null end as Monday, -- 1 col for each weekday
