从sql查询生成完整日历的json事件

我正在使用item request使用学生id检索学生的出勤信息

<Request method="GET" item="true">
    <Query>
     select subject, in_time, out_time 
     from tbl_attendance where student_id = $id
    </Query>   
</Request>

我正试图根据这个答案生成事件json

将资源xml中的SQL更改如下：

    <Query>
       SELECT subject AS title, DATE_FORMAT(in_time,'%Y-%m-%dT%T') AS start,
          DATE_FORMAT(out_time,'%Y-%m-%dT%T') AS end 
             FROM tbl_attendance WHERE student_id=$id
    </Query>

我在json中得到了T，但它现在可以工作了。e、 g.“2017-03-19T13:00:01”

    <Query>
       SELECT subject AS title, DATE_FORMAT(in_time,'%Y-%m-%dT%T') AS start,
          DATE_FORMAT(out_time,'%Y-%m-%dT%T') AS end 
             FROM tbl_attendance WHERE student_id=$id
    </Query> 

[
    {
        "end": "2017-03-18 12:00:01",
        "start": "2017-03-18 12:00:01",
        "title": "Maths"
    },
    {
        "end": "2017-03-19 13:00:01",
        "start": "2017-03-18 12:00:01",
        "title": "Bio"
    }
]
