首先，要清楚;有這樣一個例子：如何生成周表並按天和小時分割

我能得到這個查詢課程：

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

QueryResult中：

，但我想這個數據類基團;

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

我不知道該怎麼做，有人嗎？

UPDATE

新查詢：

$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");

但是，在那裏，我不能組與此查詢的問題通過HOUR(c.courseDate), DAY(c.courseDate)，因爲我得到這個錯誤：

Error: Cannot group by undefined identification or result variable.

所以，我定義小時，一天，在選擇區域變量。我不想看到日和小時爲不同的變量。

      "name": "-" 
     } 
     }, 
     "hour": "14", 
     "day": "5" 
    } 
    ] 
}

我想我現在很接近。但它一定是這樣的;

DAY 
    HOUR 
    HOUR 
DAY 
    HOUR 
    HOUR

您可以使用組通過 –

心中已經試過groupby小時和day。修復錯誤後會看到。 –

你能否給我提供一些數據的表架構 –

，讓您的視覺示例表，使用方法：

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)

要得到你提到的其他變種：

select right(date, 2), -- day of month, 
hour(date) --hour, 
course_name 
from table 
group by 1,2
