在SQL Server 2008中连接几个表以获取报告

Question

我是SQL Server数据库的新手，我还在学习基本的SQL。

请有人帮忙解决以下问题吗？

我的数据库表结构如下

现在我尝试编写一个查询来显示所有五个表中的一些记录。我目前的查询如下：

SELECT        
   Item.ItemCode, Item.ItemDescription, 
   Purchase.Date, 
   PurchaseDetails.GRNCode, PurchaseDetails.ReceivedQty, 
   Issue.Date AS Expr1, 
   IssueDetails.MRNCode, IssueDetails.IssueQty
FROM            
   Purchase 
INNER JOIN
   PurchaseDetails ON Purchase.GRNCode = PurchaseDetails.GRNCode 
INNER JOIN
   Issue 
INNER JOIN
   IssueDetails ON Issue.MRNCode = IssueDetails.MRNCode 
INNER JOIN
   Item ON IssueDetails.ItemCode = Item.ItemCode ON PurchaseDetails.ItemCode = Item.ItemCode
WHERE
   (Item.ItemCode = 10001)

它将产生如下输出，但这里的问题是一些数据正在重复突出显示

请有人帮我执行上述查询，以显示如下数据和缩短日期

因为我的表结构可以执行吗？

如果可以请某人帮助我该怎么做。

谢谢！

我为SQL做了一个尝试，这就是我想出的：

SELECT           Item.ItemCode, 
                 Item.ItemDescription, 
                 Purchase.Date, 
                 PurchaseDetails.GRNCode, 
                 PurchaseDetails.ReceivedQty, 
                 Issue.Date AS Expr1, 
                 IssueDetails.MRNCode, 
                 IssueDetails.IssueQty
FROM             Purchase 
INNER JOIN       PurchaseDetails ON Purchase.GRNCode = PurchaseDetails.GRNCode 
INNER JOIN       Item ON PurchaseDetails.ItemCode = Item.ItemCode
INNER JOIN       IssueDetails ON IssueDetails.ItemCode = Item.ItemCode
INNER JOIN       Issue ON Issue.MRNCode = IssueDetails.MRNCode
WHERE            (Item.ItemCode = 10001)
GROUP BY PurchaseDetails.GRNCode
ORDER BY Purchase.Date asc;

在加入问题表时，您似乎忘记了您的ON子句。

我添加了ORDER BY Purchase.Date asc子句，按日期按升序排列结果。

请告诉我这是否对您有所帮助:)。
