mysql将分组中的每一行按

我有一张这样的桌子：

id   weekday   money   rank
---------------------------
1    0         20      1
2    1         30      1
3    2         40      1
4    3         50      1
5    4         60      1
6    5         70      1
7    6         80      1

我想得到这个结果：

rank   Sun   Mon   Tue   Wed   Thu   Fri   Sat
----------------------------------------------
1      20    30    40    50    60    70    80

到目前为止，我的问题是：

SELECT rank,
    CASE WHEN weekday = 0 THEN money END AS 'Sun',
    CASE WHEN weekday = 1 THEN money END AS 'Mon',
    CASE WHEN weekday = 2 THEN money END AS 'Tue',
    CASE WHEN weekday = 3 THEN money END AS 'Wed',
    CASE WHEN weekday = 4 THEN money END AS 'Thu',
    CASE WHEN weekday = 5 THEN money END AS 'Fri',
    CASE WHEN weekday = 6 THEN money END AS 'Sat'
FROM weekday
GROUP BY rank

此查询仅显示sun的资金。如何修改MySQL查询以获得所需结果？

请检查：

select rank,sum(sun) as sun, 
        sum(mon) as Mon,sum(tue) as tue, 
        sum(wed) as wed, sum(thu) as thu ,
        sum(fri) as Fri, sum(sat) as sat 
    from 
        (SELECT rank, 
            CASE WHEN weekday = 0 THEN money END AS 'Sun', 
            CASE WHEN weekday = 1 THEN money END AS 'Mon', 
            CASE WHEN weekday = 2 THEN money END AS 'Tue', 
            CASE WHEN weekday = 3 THEN money END AS 'Wed', 
            CASE WHEN weekday = 4 THEN money END AS 'Thu', 
            CASE WHEN weekday = 5 THEN money END AS 'Fri', 
            CASE WHEN weekday = 6 THEN money END AS 'Sat' 
        FROM weekday where rank =1) 
    as Tbl2
    group by rank

请核对：

select rank,sum(sun) as sun, 
        sum(mon) as Mon,sum(tue) as tue, 
        sum(wed) as wed, sum(thu) as thu ,
        sum(fri) as Fri, sum(sat) as sat 
    from 
        (SELECT rank, 
            CASE WHEN weekday = 0 THEN money END AS 'Sun', 
            CASE WHEN weekday = 1 THEN money END AS 'Mon', 
            CASE WHEN weekday = 2 THEN money END AS 'Tue', 
            CASE WHEN weekday = 3 THEN money END AS 'Wed', 
            CASE WHEN weekday = 4 THEN money END AS 'Thu', 
            CASE WHEN weekday = 5 THEN money END AS 'Fri', 
            CASE WHEN weekday = 6 THEN money END AS 'Sat' 
        FROM weekday where rank =1) 
    as Tbl2
    group by rank

到目前为止，您尝试了什么查询？选择排名，工作日=0时案例，然后货币结束为“Sun”，工作日=1时案例，然后货币结束为“Mon”，工作日=2时案例，然后货币结束为“Tue”，工作日=3时案例，然后货币结束为“Wed”，工作日=4时案例，然后货币结束为“Thu”，工作日=5时案例，然后货币结束为“Fri”，案例当weekday=6时，则在

weekday

GROUP BY rank中，money以“Sat”结尾。这只显示sun money您需要编辑您的问题，并将查询添加到那里，以便其格式清晰，便于其他人查看。好的，谢谢，这是我的第一个问题。我不知道如何格式化我的word。到目前为止，您尝试了什么查询？选择rank，当工作日=0时，货币以“太阳”结尾；当工作日=1时，货币以“周一”结尾；当工作日=2时，货币以“周二”结尾；当工作日=3时，货币以“周三”结尾；当工作日=4时，货币以“周四”结尾；当工作日=5时，货币以“周五”结尾，案例：当weekday=6时，则在
