SQL Server 2008中的给定错误导致分区过度

我有以下疑问：

SELECT 
    *, 
    SUM(BalanceQty) OVER (PARTITION BY Item_Code ORDER BY [Date])
FROM 
    (SELECT
         Date, Item_Code, 
         SUM(In_Quantity) AS In_Quantity, 
         SUM(Issue_Quantity) AS Issue_Quantity, 
         (SUM(In_Quantity) - SUM(issue_Quantity)) AS BalanceQty    
     FROM
         (SELECT
              tbl_add_product.Date as Date, 
              tbl_add_product.Item_Code, 
              tbl_add_product.In_Quantity, 
              0 as Issue_Quantity 
          FROM 
              tbl_add_product
          WHERE
              Item_Code = 'pen' 

          UNION ALL

          SELECT 
              tbl_issue_product.Date as Date, 
              tbl_issue_product.Item_Code, 
              0 as In_Quantity, 
              Issue_Quantity 
          FROM
              tbl_issue_product
          WHERE
              Item_Code = 'pen') X 
    GROUP BY 
        Item_Code, Date) o

它在SQL Server 2012中工作正常，但在SQL Server 2008中导致错误。请建议解决方案。

您需要在SQL SERVER 2008中更改数据库兼容性模式，右键单击数据库选择属性，单击选项更改兼容性级别：

如果您想要一个同时适用于两者的解决方案，请尝试以下方法：

;WITH cte
     AS (SELECT Date,
                Item_Code,
                Sum(In_Quantity)                           AS In_Quantity,
                Sum(Issue_Quantity)                        AS Issue_Quantity,
                ( Sum(In_Quantity) - Sum(issue_Quantity) ) AS BalanceQty
         FROM   (SELECT tbl_add_product.Date AS Date,
                        tbl_add_product.Item_Code,
                        tbl_add_product.In_Quantity,
                        0                    AS Issue_Quantity
                 FROM   tbl_add_product
                 WHERE  Item_Code = 'pen'
                 UNION ALL
                 SELECT tbl_issue_product.Date AS Date,
                        tbl_issue_product.Item_Code,
                        0                      AS In_Quantity,
                        Issue_Quantity
                 FROM   tbl_issue_product
                 WHERE  Item_Code = 'pen') X
         GROUP  BY Item_Code,Date)
SELECT *,(select SUM(BalanceQty) from cte c2 where c2.Date <=c1.Date)
FROM   cte c1

可以使用外部应用或相关子查询执行此操作：

with t as (<your big subquery here>)
select t.*
       (select sum(BalanceQty)
        from t t2
        where t2.Item_Code = t.Item_Code and t2.[Date] <= t.[Date]
       ) as RunningBalance
from t;

如果要将结果限制为一项，可以将项_Code='pen'添加到外部查询。

在sql server 2008中，支持按分区，但不支持按顺序。解决方案是什么？解决方案：使用2012-您已经说过它可以工作，尽管提到了一个解决方案，包含实际的错误消息可能有助于将来的搜索。它在SQL Server 2008中会导致什么错误？我不确定，但如果是SQL Server 2008 smss，则不会在该组合中显示SQL Server 2012。2008下当前选择的值是什么您可以删除项目代码条件，因为根据给定的查询，所有行都将具有相同的项目代码。
