MS Access SQL 左连接不起作用

Question

无法让这个 ms JET sql 查询（查询我没有编写的 2007 Access 数据库）工作。错误提到“参数太少，需要 4 个”。我认为这与我的 JOIN 有关。

有人知道我错过了什么吗？

SELECT TOP 500 [Load Items].[LoadItemsID] AS load_order_line_id,
        lo.[LoadOrderID] AS load_order_id,
        sp.[Description] AS product_description,
        sp.[Common Name] AS product_common_name,
        c.[Bill To Name] AS company_name,
        lp.[Ship Date] AS ship_date,
        al.[Ordered] AS order_quantity,
        al.[Price] AS sell_price,
        a.[Order Date] AS order_date,
        a.[Due Date] AS due_date
        FROM ((((((([Load Items]
            LEFT JOIN [Acknowledgement Lines] AS al
                ON al.[AcknowledgmentLineID] = [Load Items].[AcknowledgmentLineID])
            LEFT JOIN [Product] AS p
                ON p.[ProductID] = al.[ProductID])
            LEFT JOIN [Product Master] AS pm
                ON pm.[ProductMasterID] = p.[ProductMasterID])
            LEFT JOIN [Species] AS sp
                ON sp.[SpeciesID] = pm.[SpeciesID])
            LEFT JOIN [Acknowledgement] AS a
                ON a.[AcknowledgmentID] = al.[AcknowledgmentID])
            LEFT JOIN [Customer] AS c
                ON c.[CustomerID] = a.[CustomerID])
            LEFT JOIN [Load Orders] AS lo
                ON lo.[LoadOrderID] = [Load Items].[LoadOrderID])
            LEFT JOIN [Load Planner] AS lp
                ON lp.[LoadPlannerID] = lo.[LoadPlannerID]
        GROUP BY [Load Items].[LoadItemsID],
            lo.[LoadOrderID],
            sp.[Description],
            sp.[Common Name],
            c.[Bill To Name],
            lp.[Ship Date],
            al.[Ordered],
            al.[Price],
            a.[Order Date],
            a.[Due Date];

最可能的原因是字段名称中的拼写错误。就解析器而言，与您尝试在表中访问的字段名称不正确匹配的每个带括号的字段名称都是一个缺失参数。
