我在编写此SQL查询时遇到困难

Question

我是这里的新手，所以我很抱歉立即提出一个（我认为是）困难的问题，但我被困住了，希望你们能为我提供帮助。我已为其附上一张图像，该图像显示了我的表设计以及它们之间的关系（MS Access的屏幕截图）。这可能有助于阅读我的问题时看到：

我正在尝试编写一个查询，该查询给出了“客户参与”表中的“会计年度结束”，并返回当前年份（会计年度结束）“客户K1”中不存在的“投资名称”字段/ Tax Report”列表中列出了上一会计年度末存在的DID / DO。

基本上，我想要一个列表，其中存在去年的投资名称列表，而今年没有报告/列表。

请原谅我的基本语法技能或我可能犯的任何错误。

在此先感谢您提供的任何帮助！

我现在的SQL代码是：

PARAMETERS [CURRENT FISCAL YEAR] DateTime, [COMPARATIVE FISCAL YEAR] DateTime;
SELECT Investments.[Investment Name], [Client Engagement].[Fiscal Year End]
FROM Investments INNER JOIN ([Investment Year] INNER JOIN ([Client Engagement] INNER JOIN [Client K1/Tax Report] ON [Client Engagement].EngagementID = [Client K1/Tax Report].[Client Engagement ID]) ON [Investment Year].[Investment FS ID] = [Client K1/Tax Report].[Investment FS ID]) ON Investments.[Investment Name] = [Investment Year].[Investment Name]
WHERE ((([Client Engagement].[Fiscal Year End])=[CURRENT FISCAL YEAR])) NOT IN
(
SELECT Investments.[Investment Name], [Client Engagement].[Fiscal Year End]
FROM Investments INNER JOIN ([Investment Year] INNER JOIN ([Client Engagement] INNER JOIN [Client K1/Tax Report] ON [Client Engagement].EngagementID = [Client K1/Tax Report].[Client Engagement ID]) ON [Investment Year].[Investment FS ID] = [Client K1/Tax Report].[Investment FS ID]) ON Investments.[Investment Name] = [Investment Year].[Investment Name]
WHERE ((([Client Engagement].[Fiscal Year End])=[COMPARATIVE FISCAL YEAR]))
)

经过格式化以提高可读性：

PARAMETERS [CURRENT FISCAL YEAR] DATETIME
    ,[COMPARATIVE FISCAL YEAR] DATETIME;

SELECT Investments.[Investment Name]
    ,[Client Engagement].[Fiscal Year End]
FROM Investments
INNER JOIN (
    [Investment Year] INNER JOIN (
        [Client Engagement] INNER JOIN [Client K1/Tax Report] ON [Client Engagement].EngagementID = [Client K1/Tax Report].[Client Engagement ID]
        ) ON [Investment Year].[Investment FS ID] = [Client K1/Tax Report].[Investment FS ID]
    ) ON Investments.[Investment Name] = [Investment Year].[Investment Name]
WHERE ((([Client Engagement].[Fiscal Year End]) = [CURRENT FISCAL YEAR])) NOT IN (
        SELECT Investments.[Investment Name]
            ,[Client Engagement].[Fiscal Year End]
        FROM Investments
        INNER JOIN (
            [Investment Year] INNER JOIN (
                [Client Engagement] INNER JOIN [Client K1/Tax Report] ON [Client Engagement].EngagementID = [Client K1/Tax Report].[Client Engagement ID]
                ) ON [Investment Year].[Investment FS ID] = [Client K1/Tax Report].[Investment FS ID]
            ) ON Investments.[Investment Name] = [Investment Year].[Investment Name]
        WHERE ((([Client Engagement].[Fiscal Year End]) = [COMPARATIVE FISCAL YEAR]))
        )
