Question

想像下面的图[] [2]一样显示每月和每年的所有支出，并且代码如下所示

SELECT 
    monthname(date_added) as monthname,
    year(date_added) as year,
    SUM(amount) as amounts 
    FROM incomes GROUP BY year ORDER BY monthname

2017年
一月$ 100
2月$ 200
7月$ 90
6月$ 300

2018年
一月$ 100
2月$ 200
7月$ 90
6月$ 300

Answer 1

似乎您需要按日期和月份订购

    select t.year, t.monthname, t.amounts
    from(
         SELECT monthname(date_added) as monthname, 
                month(date_added) month, 
                year(date_added) as year,
                SUM(amount) as amounts 
                FROM incomes 
                GROUP BY year, month, monthname
    )
    ORDER BY t.year, t.month

或者如果您需要今年和前一年的两个分开的结果

对于实际年份，您可以

select t.year, t.monthname, t.amounts
from(
     SELECT monthname(date_added) as monthname, 
            month(date_added) month, 
            year(date_added) as year,
            SUM(amount) as amounts 
            FROM incomes 
            where year(date_added) = year(curdate())
            GROUP BY year, month, monthname
)
ORDER BY t.year, t.month

上一年您可以

select t.year, t.monthname, t.amounts
from(
     SELECT monthname(date_added) as monthname, 
            month(date_added) month, 
            year(date_added) as year,
            SUM(amount) as amounts 
            FROM incomes 
            where year(date_added) = year(curdate()) -1 
            GROUP BY year, month, monthname
)
ORDER BY t.year, t.month
