mySQL子查询

Question

我写了这个代码，它有以下结果，现在我想总结一下联合后得到的两行的结果。 任何想法我怎么能这样做（我的意思是我需要在这个新的“桌子”上另一个选择）。 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......
