Mysql 已添加具有相同密钥的项-SQL Server 2012子查询问题

我正在SQL server 2012中编写代码，以便将其传输到报表生成器3.0的查询设计器中

我的代码在Management studio中运行完美，在actualy query designer中也可以运行，但在query designer中按OK后，它会抛出错误：

"Could not update a list of fields for the query. Verify that you can connect to the data source and that your query syntax is correct"

详情如下：

"An item with the same key has already been added"

这是我正在使用的代码：

Select * 
from
(Select distinct srt.Name,
    percentile_disc(.5) WITHIN GROUP(ORDER BY (sr.price)) OVER(PARTITION BY srt.Name) AS    MedianSpend
    from ServiceReq sr inner join ServiceReqTemplate srt 
    on srt.RecId = sr.SvcReqTmplLink_RecID Where Name like '%') medQuery
    inner join

(select distinct srt.Name,
    cast(sum(sr.price) as int) as AvgCost,cast(sum(sr.cost) as int) as 
    AvgTransCost,cast(avg(sr.TotalTimeSpent) as int) as TotalTimeSpent
    from ServiceReq sr, ServiceReqTemplate srt
    where sr.SvcReqTmplLink_RecID = srt.RecId
    group by srt.Name) avgQuery
    on medQuery.Name LIKE avgQuery.Name

我认为问题是在一个表中会有两列同时被称为Name，这是不允许的。我想我可以在同一个表中添加另一列，并将其命名为Name_2，然后将Name表中的所有数据复制并粘贴到Name_2中，然后使用它。这是在报表生成器中成功实现此代码的最简单方法吗？

您可以将asname2添加到第二个查询中，然后在最后的avgQuery之后调用它
