Question

以下是我正在使用的两个表：

NBAGameLog：

Player_ID, Team, Minutes, Date_Played

玩家：

Player_ID, First Name, Last Name, Position

我现在有这两个问题：

AvgMP15：

SELECT DISTINCTROW Players.FirstName, Players.LastName, Players.Position, NBAGameLog.Tm, ROUND(AVG(AvgMP1),2) AS AvgMP
FROM (SELECT Players.FirstName, Players.LastName, Players.Position, NBAGameLog.Tm, ROUND(AVG(NBAGameLog.MP),2) As AvgMP1
FROM NBAGameLog INNER JOIN Players ON NBAGameLog.Player_ID = Players.Player_ID
WHERE (((NBAGameLog.Date_Played) Between Date()-15 And Date()))
GROUP BY NBAGameLog.Date_Played, Players.Position, NBAGameLog.FD_Points, Players.FirstName, Players.LastName, NBAGameLog.Tm, Players.Player_ID)  AS [%$##@_Alias]
GROUP BY Players.FirstName, Players.LastName, Players.Position, NBAGameLog.Tm;

AvgMP：

SELECT DISTINCTROW p.FirstName, p.LastName, gl.Tm, ROUND(Avg(gl.MP),2) AS AvgMPS
FROM NBAGameLog AS gl INNER JOIN Players AS p ON gl.Player_ID = p.Player_ID
GROUP BY p.FirstName, p.LastName, gl.Tm
ORDER BY Avg(gl.MP) DESC;

第一个给我一个球员的名字，位置，球队和他在过去15场比赛中的平均上场时间。

第二个给了我他整个赛季的平均上场时间。

我想比较这两个，所以我想要一个提取的查询：

名字，姓氏，位置，球队，分钟在过去的15场比赛中出场，整个赛季的分钟比赛，15场和赛季之间的差距。

这可能吗？

Answer 1

我明白了！

以下是查询：

SELECT DISTINCTROW p.FirstName, p.LastName, gl.Tm, ROUND(Avg(gl.MP),2) AS Season, ROUND(Avg(gl2.MP),2) AS Last15, ROUND((Last15-Season),2) AS Diff
FROM (NBAGameLog AS gl INNER JOIN Players AS p ON gl.Player_ID = p.Player_ID) INNER JOIN NBAGameLog AS gl2 ON gl2.Player_ID = gl.Player_ID
WHERE gl2.Date_Played Between Date()-15 And Date()
GROUP BY p.FirstName, p.LastName, gl.Tm
ORDER BY p.LastName;

组合两个查询的字段
