sql查詢左連接mysql的VS MS-Access數據庫

Question

此查詢

SELECT * 
FROM tblContracts 
LEFT JOIN tblPartys ON tblContracts.id = tblPartys.Contract_id 
INNER JOIN tblAdministrators 
     ON tblContracts.AdministratorID = tblAdministrators.ID 

作品上的MySQL數據庫，但它並沒有對Access數據庫工作！

我收到此錯誤的打擊：

System.Data.OleDb.OleDbException：在 查詢表達式「tblContracts.id = tblPartys.Contract_id語法錯誤（缺少操作員）INNER JOIN tblAdministrators ON tblContracts。 AdministratorID = tblAdministrators.I'。在在 System.Data.OleDb.OleDbCommand.ExecuteCommandTextForSingleResult System.Data.OleDb.OleDbCommand.ExecuteCommandTextErrorHandling（OleDbHResult 小時）在 System.Data.OleDb.OleDbCommand.ExecuteCommandText（對象&（tagDBPARAMS dbParams，對象&的ExecuteReuslt） 的ExecuteReuslt）在 System.Data.OleDb.OleDbCommand.ExecuteCommand（的CommandBehavior 行爲，在 System.Data.OleDb對象在 System.Data.OleDb.OleDbCommand.ExecuteReaderInternal（的CommandBehavior 行爲，字符串方法）&的ExecuteReuslt）。 OleDbCommand.ExecuteReader（CommandBehavior行爲）

Answer 1

嘗試添加一對夫婦括號圍繞首次加入

SELECT * 
FROM (tblContracts 
LEFT JOIN tblPartys ON tblContracts.id = tblPartys.Contract_id) 
INNER JOIN tblAdministrators 
     ON tblContracts.AdministratorID = tblAdministrators.ID 

Answer 2

從您發佈的錯誤，則miswrite ON tblContracts.AdministratorID = tblAdministrators.ID成ON tblContracts.AdministratorID = tblAdministrators.I所解釋：

語法錯誤（缺少操作者）在查詢表達式「tblContracts.id = tblPartys.Contract_id INNER JOIN tblAdministrators ON tblContracts.AdministratorID = tblAdministrators.I'。在...

所以確保它是這樣寫ON tblContracts.AdministratorID = tblAdministrators.ID

Answer 3

試試這個：

SELECT * FROM ((tblContracts 
    LEFT JOIN tblPartys ON tblContracts.id = tblPartys.Contract_id) 
    INNER JOIN tblAdministrators ON tblContracts.AdministratorID = tblAdministrators.ID) 

根據我的經驗，如果你問我，Access喜歡括號......太多了。
