【问题标题】："Join expression not supported" for multiple Left Join in MS AccessMS Access 中多个左连接的“连接表达式不支持”

【问题描述】：

我在我的 ASP.NET 项目中作为字符串传递了以下查询：

SELECT creditorName, amount, interestRate, interestType, interestCalculationMethod, insertedDate, o.fullName AS owner, u.fullName AS dataInsertedBy FROM ((tbl_savings s) LEFT JOIN tbl_users o ON (ownerID = o.userID)) LEFT JOIN tbl_users u ON (dataEnteredByID = u.userID);

我收到以下错误：

+       $exception  {"Join expression not supported."}  System.Data.OleDb.OleDbException

我使用 MS Access 2016 作为数据库。

怎么了？

对于没有在我发布的链接中提供正确答案，我深表歉意。正确答案如下：

select savingsID, creditorName, amount, interestRate, interestType, interestCalculationMethod, insertedDate, ownerID, o.fullName as owner, u.fullName as dataEnteredBy from((tbl_savings as s) left join tbl_users as o on s.ownerID = o.userID) left join tbl_users as u on s.dataEnteredByID = u.userID
