Question

无法使此ms JET sql查询（查询我未编写的2007 Access数据库）正常工作。错误提到“参数太少，期望4”。我相信这与我的加入有关。

有人知道我想念什么吗？

SELECT TOP 500 [Load Items].[LoadItemsID] AS load_order_line_id,
        lo.[LoadOrderID] AS load_order_id,
        sp.[Description] AS product_description,

        c.[Bill To Name] AS company_name,

        al.[Price] AS sell_price,

最可能的原因是字段名称中的拼写错误。就解析器而言，每个与表中试图访问的字段名称都不正确匹配的带括号的字段名称都是一个缺少的参数。
