php – 如何生成星期表并按日和小时分组

分类：PHP作者：编程之家

首先,要明确;有一个这样的例子：

enter image description here

我可以通过这个查询获得课程：

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

QueryResult中：

    },
    {
      "id": 141,
      "name": "Crunch 30 Min.",

      },
      "trainer": {
        "id": 1,
        "name": "-"
      }
    }   ] }

但我想将这些数据分组为;

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

我不知道怎么做,有人吗？

UPDATE

新查询：

   $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;这个查询有问题我不能按小时(c.courseDate),DAY(c.courseDate)分组,因为我收到了这个错误：

Error: Cannot group by undefined identification or result variable.

因此,我将时间和日期定义为选择区域中的变量.
我不希望将日和小时视为不同的变量.

}

我想我现在很接近.但它一定是这样的;

DAY
    HOUR
    HOUR
DAY
    HOUR
    HOUR

解决方法:

要获取可视化示例表,请使用：

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)

要获得您提到的其他变体：

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