Question

我有以下查询，我在ASP.NET项目中作为字符串传递：

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？

我在MSDN上找到了解决方案。这是链接：

我很抱歉没有提供正确的答案以及我发布的链接。这是正确的答案：

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

对于MS Access中的多个Left Join，“不支持连接表达式”
