Question

 SELECT  
   Incoming.`Incoming_ItemNumber` AS ItemNumber,
   Incoming.`Date_Incoming` AS 'Date',
   allItems.`Description` , Incoming.`Quantity` ,
   Incoming.`Supplier` , Incoming.`Invoice_Number` ,
   Incoming.`Price` , Incoming.`JO` 
FROM 
   allItems 
INNER JOIN 
   Incoming ON allItems.Item_Number = Incoming.Item_Number;

我在MS Access 2013中尝试过此代码，但是如果我在Ireport中为我的报表创建查询时使用相同的代码，则会出现以下错误：

java.sql.SQLException：[Microsoft] [ODBC Microsoft Access Driver] Too 几个参数。预计1。

查询有效如果我只使用一个表，但如果我尝试连接两个表，这就是我得到的：

Query error

编辑：我要做的是从表传入和allItems中获取值

以下是我的表格的内容：

allItems：Item_Number [primary]，描述传入：Incoming_ItemNumber [主]，ITEM_NUMBER [外国]，Date_Incoming，数量，供应商，INVOICE_NUMBER，单价，金额，JO

请注意，我使用的查询在MS ACCESS 2013中正常运行

Answer 1

在我的代码中经过大量实验后，我想出了自己的解决方案：

1。）我重新 - ＆＃34;链接＆＃34;我的表关系

2.。）我使用MS Access使用查询设计工具创建了一个新查询其中：我选择了我需要的表格和数据列并按日期排序

3。）我保存了查询设计并转到了SQL查看＆＃39;

4.。）我复制了sql查询。

5.）转到我的IReport报告查询并粘贴在那里

然后我点击了“查询查询”。按钮

并且它有效。这是Access生成的代码：

SELECT 
   allItems.Item_Number,
   Incoming.Date_Incoming,
   allItems.Description,
   Incoming.Quantity, 
   Incoming.Supplier,
   Incoming.Invoice_Number,
   Incoming.Price,
   Incoming.Amount,
   Incoming.JO
FROM 
   allItems 
RIGHT JOIN 
   Incoming 
ON 
   allItems.Item_Number = Incoming.Item_Number
ORDER BY 
   Incoming.Date_Incoming ASC;

MS Access：INNER JOIN的问题
