c# - 通过导致数据网格失败进行分组

Question

我有 ac# 应用程序，其 GUI 具有数据网格，目前正在使用以下 sql 填充

      UPDATE    mi
      SET       mi.ClientName = c.ClientName
      FROM      generic.MasterInventory mi INNER JOIN
                generic.Client c ON mi.FK_Client = c.PK_Client
      SELECT DISTINCT 
                ClientName, FundName, PK_MasterInventory, FK_Fund, FK_Client, ISIN,  Status, ShareCurrency, PriceFrequency, ClassCode, Simulation, Hedged, 
                                              FundCurrency, [Type]                                                             FROM         generic.MasterInventory

但是我无法删除重复的记录。我试过使用 groupby

      UPDATE    mi
      SET       mi.ClientName = c.ClientName
      FROM      generic.MasterInventory mi INNER JOIN
                generic.Client c ON mi.FK_Client = c.PK_Client
      SELECT DISTINCT 
                ClientName, FundName, PK_MasterInventory, FK_Fund, FK_Client, ISIN,  Status, ShareCurrency, PriceFrequency, ClassCode, Simulation, Hedged, 
                                              FundCurrency, [Type]                                                               FROM         generic.MasterInventory
       GROUP BY ClientName

然而，这样做会导致一个空的数据网格......有谁知道为什么这是/一种解决方法？

在查询生成器中运行 Group by 会给出此错误消息

      Column generic.masterInventory.FundName is invalid 
      in the select list because it is not contained in 
      either an aggregate function or the group by clause
