SQL-DateAdded 函数和 Sum 问题

Question

我有以下查询：

SELECT 
    p.name as Name, SUM(r.attempts) as Attempts, SUM(r.gains) as Positive,       
    SUM(r.losses) as Negative, SUM(r.yards) as Net, SUM(r.touchdowns) as TD,
    SUM(r.longest) as Long, year(g.date_) as Season 
FROM 
    Rush AS r 
INNER JOIN                
    PlayerGame AS pg ON r.playerGame_Id = pg.playerGame_Id 
INNER JOIN 
    Players AS p ON p.player_Id = pg.player_Id
INNER JOIN 
    Games as g ON g.game_Id = pg.game_Id 
WHERE
    g.date_ LIKE CASE 
                    WHEN month(g.date_) = 1 
                       THEN DATEADD(year, -1, g.date_)
                    ELSE g.date_ 
                 END
GROUP BY
    year(date_), name
ORDER BY 
    Season DESC, Attempts DESC, Positive, Negative, Net, TD, Long

我正在尝试获取每个赛季所有统计数据的总和。我正在尝试将一月份的所有额外比赛添加到整个赛季。当我运行这个查询时，季节与一月份的日期是分开的。但是，对于 1 月份进行的所有比赛，它不会将它们添加到所有尝试、码数等的总和中。如果有人可以提供帮助或者如果您需要额外的背景信息，请告诉我。谢谢

Answer 1

您应该使用减去月份的年份这是 mysql

SELECT p.name as Name, SUM(r.attempts) as Attempts, SUM(r.gains) as Positive,       
SUM(r.losses) as Negative, SUM(r.yards) as Net, SUM(r.touchdowns) as TD,
SUM(r.longest) as Long, year(DATE_SUB(date_,INTERVAL 1  MONTH)) as Season 
FROM Rush AS r INNER JOIN                
PlayerGame AS pg ON r.playerGame_Id = pg.playerGame_Id 
INNER JOIN Players AS p ON p.player_Id = pg.player_Id
INNER JOIN Games as g ON g.game_Id = pg.game_Id 

Group by year(DATE_SUB(date_,INTERVAL 1  MONTH)), name
Order by Season DESC, Attempts DESC, Positive, Negative, Net, TD, Long

这用于 sql-服务器

SELECT p.name as Name, SUM(r.attempts) as Attempts, SUM(r.gains) as Positive,       
SUM(r.losses) as Negative, SUM(r.yards) as Net, SUM(r.touchdowns) as TD,
SUM(r.longest) as Long, year(DATEADD(month, -1, date_)) as Season 
FROM Rush AS r INNER JOIN                
PlayerGame AS pg ON r.playerGame_Id = pg.playerGame_Id 
INNER JOIN Players AS p ON p.player_Id = pg.player_Id
INNER JOIN Games as g ON g.game_Id = pg.game_Id 

Group by year(DATEADD(month, -1, date_)), name
Order by Season DESC, Attempts DESC, Positive, Negative, Net, TD, Long

Answer 2

创建一个包含 Season、SeasonStart 和 SeasonEnd.

列的 table Seasons

SELECT p.name as Name, SUM(r.attempts) as Attempts, SUM(r.gains) as Positive,       
SUM(r.losses) as Negative, SUM(r.yards) as Net, SUM(r.touchdowns) as TD,
SUM(r.longest) as Long, s.Season as Season 
FROM Rush AS r INNER JOIN                
PlayerGame AS pg ON r.playerGame_Id = pg.playerGame_Id 
INNER JOIN Players AS p ON p.player_Id = pg.player_Id
INNER JOIN Games as g ON g.game_Id = pg.game_Id 
INNER JOIN Seasons AS s on g.date_ BETWEEN s.SeasonStart AND s.SeasonEnd
Group by s.Season, name
Order by s.Season DESC, Attempts DESC, Positive, Negative, Net, TD, Long

那么对特殊日期逻辑的需求就消失了，由 table 表示。
