Question

通过select语句检索数据集时，我想基于每个检索到的记录的列中的值来更新现有记录。我不能使用函数来更新记录，也不能在select语句中使用存储过程。我还认为我无法通过从函数执行存储过程来规避这些限制。

有什么想法吗？以下是带有注释的当前代码，我觉得我需要调用一些会更新记录的内容。该代码将在SSRS中使用，因此一种解决方案可能是在报表自定义代码中执行存储过程，但我也无法使它正常工作。

在数据查询之前将UPDATE查询添加到报表查询的TSQL中。只要您的查询有效且具有权限，SSRS就会运行TSQL来更新数据，使用TEMP表等。SSRS查询编辑器可能不喜欢您可以做的所有事情，因此您可能需要在SSMS中进行查询（无论如何我通常都会这样做。

我认为您的查询将类似于：

UPDATE sw
SET Update_Mode = CASE WHEN ab.ABURRF >0 THEN 'Manually Update'
                        ELSE CASE WHEN @Update_Mode ='Yes' THEN 'Yes/Error' ELSE @Update_Mode END
                        END
FROM [dbo].[crp_F44H501] sw  
INNER JOIN [dbo].[stg_F0101] ab on ab.aban8 = sw.SMBYR


select sw.SMACTVSEQ as JDE_ActiveRec 
    ,sw.SMCSSEQ as JDE_SalesSeq
    ,bu.MCRP04 as JDE_DivID
    ,sw.SMHBMCUS as JDE_CommID
    ,cm.CMDL01 as JDE_CommunityName
    ,rtrim(sw.SMMCU) as JDE_LotID
    ,sw.SMBYR as JDE_BuyerABNo
    ,JDE_SSID = case
        When ab.ABURRF is null then cast(0 as int)
        When ab.ABURRF = '' then cast(0 as int)
        else cast(ab.ABURRF as int)
        end
    ,ss.Customer_ID as SS_CustID
    ,ss.Lot_ID as SS_LotID
    ,ss.Customer_Status as SS_CustStatus
    ,[dbo].[udf_ConvertJDEdate](sw.SMCDJ) as JDE_DateClosed
    ,sw.Update_Mode

请记住，必须在运行此更新之前声明@Update_Mode变量，否则会出现错误。
