Question

我无法将每日数据（已汇总到月度数据）与月度数据相关联。我在Excel中有一个财务数据库，有两个表：

支出 - 购买时所有带有类别和日期（日/月/年）的购买
收入 - 按日期（月/年）的月收入

我有一个查询，它将每日支出汇总并按月分组：

SELECT Format(Outlays.period,"mmm-yy") AS Period, Sum(Outlays.Value) AS [Living Cost]
FROM Outlays
GROUP BY Format(Outlays.period,"mmm-yy"), Outlays.[Living Cost]
HAVING (((Outlays.[Living Cost])=True));

我遇到麻烦的地方是将收入数据加入此查询：

SELECT Format(Outlays.period,"mmm-yy") AS Period, Sum(Outlays.Value) AS [Living Cost]
FROM Outlays
JOIN Income ON Outlays.period = Income.Period
GROUP BY Format(Outlays.period,"mmm-yy"), Outlays.[Living Cost]
HAVING (((Outlays.[Living Cost])=True));

此查询返回“FROM子句中的语法错误”。

非常感谢有关正确语法的任何想法。

在MS Access SQL中，您需要显式声明JOIN的类型，而不是将其一般地保留为JOIN。而在其他RDMS中，JOIN默认为INNER JOIN，在MS Access中您必须声明它。

FROM Outlays INNER JOIN Income ON Outlays.period = Income.Period

对于多个连接，必须将表/查询配对括在括号中：

FROM ((Outlays 
INNER JOIN Income ON Outlays.period = Income.Period)
INNER JOIN OtherTable ON Outlays.id = OtherTable.id)
INNER JOIN AnotherTable ON Outlays.id = AnotherTable.id

使用每月数据MS-Access 2010加入每日数据
