mysql - mySQL 子查询

Question

我编写了这段代码，它具有以下结果，现在我想将联合后获得的两行的结果相加。知道我该怎么做（我的意思是我需要在这个新的“表”上进行另一个选择）。任何帮助表示赞赏

SELECT Date_format(`creation`, '%Y-%m-%d') AS short_date,
       Sum(`param7`)                       AS time_spent_in_sessions,
       Count(*)                            AS nb_of_sessions
FROM   `f_colony_ios_play_resume_pn__20120823`
WHERE  `id` IN ( '22965', '22966' )

UNION

SELECT Date_format(`creation`, '%Y-%m-%d') AS short_date,
       Sum(`param8`)                       AS time_spent_in_sessions,
       Count(*)                            AS nb_of_sessions
FROM   `f_colony_ios_play_resume_pn__20120823`
WHERE  `id` IN ( '22970', '22971' )

-----------------------------
result:
    short_date       time_spent_in_sessions      nb_of_sessions
    2012-08-23               7                        2
    2012-08-23               10                       1

Answer 1

SELECT short_date, SUM(time_spent_in_sessions), SUM(nb_of_sessions) 
FROM (both your queries here) AS subquerytable

我认为这是要走的路...
