如何在 MS Access 中使用 RIGHT JOIN 连接表

Question

我对以下 SQL 有疑问：

SELECT tours_atp.NAME_T
      ,today_atp.TOUR
      ,today_atp.ID1
      ,today_atp.ID2
      ,qry_today_Elo_ov_prep_atp.LastOfnElo_Ov AS ID1_nElo_ov
FROM (today_atp INNER JOIN tours_atp ON today_atp.TOUR = tours_atp.ID_T)
INNER JOIN qry_today_Elo_ov_prep_atp ON today_atp.ID1 = qry_today_Elo_ov_prep_atp.ID
WHERE ((tours_atp.RANK_T Between 1 And 4) AND today_atp.RESULT="")
ORDER BY tours_atp.NAME_T;

它工作正常。

我现在想使用RIGHT JOIN将另一个表构建到查询中，如下所示：

RIGHT JOIN qry_today_Elo_sur1_prep_atp ON qry_today_Elo_sur1_prep_atp.ID = today_atp.ID1

我尝试将其添加到FROM的末尾，如下所示：

SELECT tours_atp.NAME_T, today_atp.TOUR, today_atp.ID1, today_atp.ID2, qry_today_Elo_ov_prep_atp.LastOfnElo_Ov AS ID1_nElo_ov
FROM ((today_atp INNER JOIN tours_atp ON today_atp.TOUR = tours_atp.ID_T) INNER JOIN qry_today_Elo_ov_prep_atp ON today_atp.ID1 = qry_today_Elo_ov_prep_atp.ID) RIGHT JOIN qry_today_Elo_sur1_prep_atp ON qry_today_Elo_sur1_prep_atp.ID = today_atp.ID1
WHERE (((tours_atp.RANK_T) Between 1 And 4) AND ((today_atp.RESULT)=""))
ORDER BY tours_atp.NAME_T;

但是，我收到“不支持 JOIN 表达式”错误 - 为什么会这样？ 正确的语法是什么样的？

尝试将其粘贴到 SQL 编辑器中，让 MSAccess 添加它想要的 ()：

SELECT tours_atp.NAME_T
     , today_atp.TOUR
     , today_atp.ID1
     , today_atp.ID2
     , qry_today_Elo_ov_prep_atp.LastOfnElo_Ov AS ID1_nElo_ov
FROM today_atp 
INNER JOIN tours_atp 
   ON today_atp.TOUR = tours_atp.ID_T
  and tours_atp.RANK_T Between 1 And 4
  and today_atp.RESULT=""
INNER JOIN qry_today_Elo_ov_prep_atp 
   ON today_atp.ID1 = qry_today_Elo_ov_prep_atp.ID
RIGHT JOIN qry_today_Elo_sur1_prep_atp 
   ON qry_today_Elo_sur1_prep_atp.ID = today_atp.ID1
ORDER BY tours_atp.NAME_T

或重新安排使用左...

SELECT tours_atp.NAME_T
     , today_atp.TOUR
     , today_atp.ID1
     , today_atp.ID2
     , qry_today_Elo_ov_prep_atp.LastOfnElo_Ov AS ID1_nElo_ov
FROM qry_today_Elo_sur1_prep_atp 
LEFT JOIN today_atp 
   ON qry_today_Elo_sur1_prep_atp.ID = today_atp.ID1
INNER JOIN tours_atp 
   ON today_atp.TOUR = tours_atp.ID_T
  and tours_atp.RANK_T Between 1 And 4
  and today_atp.RESULT=""
INNER JOIN qry_today_Elo_ov_prep_atp 
   ON today_atp.ID1 = qry_today_Elo_ov_prep_atp.ID 
ORDER BY tours_atp.NAME_T
