訪問SQL JOIN表達式不支持

Question

我知道在這裏處理不支持的連接表達式時存在一堆問題，我找不到指向我的情況的問題。

我的查詢看起來是這樣的：

SELECT T1.*, T2.Year, T3.Force, T4.Group AS myGroup 
FROM ((AllQuestions AS T1 
INNER JOIN Years AS T2 ON T1.ID_Year = T2.ID) 
INNER JOIN Forces AS T3 ON T1.Questions_Force = T3.ID) 
INNER JOIN Groups AS T4 ON T4.ID = " & (Me.Texte423) & " 
ORDER BY Categories, T1.Questions; 

正如你可以在網上指的T4，我想匹配表族的ID在報告中從匹配的文本框的值看（它可能很重要）。

我收到的錯誤看起來像：不支持JOIN表達式。 「看起來」，因爲我使用法語版的Access，所以它是一個基本的翻譯...

我在做什麼錯誤請？

Answer 1

我想你會需要CROSS JOIN表Groups，然後將T4.ID查詢的WHERE子句中，但這並不解決可能T4.ID和正在使用加入其他ID列之間存在的關係其他表：

SELECT T1.*, T2.Year, T3.Force, T4.Group AS myGroup 
FROM ((AllQuestions AS T1 
INNER JOIN Years AS T2 ON T1.ID_Year = T2.ID) 
INNER JOIN Forces AS T3 ON T1.Questions_Force = T3.ID) 
CROSS JOIN Groups AS T4 
WHERE T4.ID = " & (Me.Texte423) & " 
ORDER BY Categories, T1.Questions; 

如果有團體和ID AllQuestions之間的關係，那麼你需要繼續沿着這條修改查詢：

SELECT T1.*, T2.Year, T3.Force, T4.Group AS myGroup 
FROM ((AllQuestions AS T1 
INNER JOIN Years AS T2 ON T1.ID_Year = T2.ID) 
INNER JOIN Forces AS T3 ON T1.Questions_Force = T3.ID) 
INNER JOIN Groups AS T4 ON T1.{Group ID Relation} = T4.ID 
WHERE T4.ID = " & (Me.Texte423) & " 
ORDER BY Categories, T1.Questions; 

Answer 2

你不能那樣做。但是你可以修改查詢的SQL。其設置爲：

SELECT T1.*, T2.Year, T3.Force, T4.Group AS myGroup 
FROM ((AllQuestions AS T1 
INNER JOIN Years AS T2 ON T1.ID_Year = T2.ID) 
INNER JOIN Forces AS T3 ON T1.Questions_Force = T3.ID) 
INNER JOIN Groups AS T4 ON T4.ID = {0} 
ORDER BY Categories, T1.Questions; 

然後設置/修改SQL當你需要它：

MyQdy.SQL = Replace(SQL, "{0}", Me!Texte423.Value)
