How to Generate a Week Table and Split by Day and Hour
Question
First, to be clear; there is an example like this:
I can get courses with this query:
$qb
->select("c")
->from("ATLReservationBundle:Course", "c")
->where("WEEK(c.courseDate, 1) = WEEK(CURRENT_DATE(), 1)")
->orderBy("c.courseDate", "ASC");
QueryResult:

But i want to group this data like;
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 Query:
$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 got this error:
Error: Cannot group by undefined identification or result variable.
So, i defined hour and day as variable in select area. I don't want to see day and hour as different variables.

"id": 1,

}
},
"hour": "14",
"day": "5"
}
]
}
I think i'm close now. But it must be like;
DAY
HOUR
HOUR
DAY
HOUR
HOUR

TO get your visual example table, use:
WEEKDAY(date)
Returns the weekday index for date (0 = Monday, 1 = Tuesday, … 6 = Sunday
select hour(date), -- group by hour
case when weekday(date)=0 then course_name else null end as Monday, -- 1 col for each weekday
.....
case when weekday(date)=6 then course_name else null end as Sunday
from table
where -- select a monday to sunday calendar week unique by year
date(date) - interval weekday(date)=date(curdate()) - interval weekday(curdate())
group by hour(date)
To get the other variant you mentioned:
select right(date, 2), -- day of month,
hour(date) --hour,
course_name
from table
group by 1,2
