sql - SSIS使用参数映射多步骤执行SQL任务

Question

我有一个 DTSX 文件，其中有一个更新语句，该语句在更新语句中从自身进行选择，并且它正在填充临时数据库。它在更新语句中使用变量的参数映射。

我重写了它，首先将 select 语句运行到临时表中，然后运行 ​​update 语句，但出现以下错误“多步 OLE DB 操作生成错误...”

我对SSIS包不太熟悉，想知道我是否写错了语句。

下面是查询。请注意底部的更新语句有“？”在其中，我认为这会将参数映射到它。

我认为主要问题是由别名引起的，因为您在 FROM 子句中将 currentdata 作为 stg_fct_rierfi​​nancial 的别名，但您没有在UPDATE 子句。

尝试使用以下查询:

update currentdata
    set currentdata.cafi_freqkey = newdata.cafi_freqkey,
    currentdata.cafi_carrierchargekey = newdata.cafi_carrierchargekey,
    currentdata.cafi_carrierratekey = newdata.cafi_carrierratekey,
    currentdata.cafi_modifyloadkey = ?
from stg_fct_carrierfinancial currentdata 
inner join (select
        cafi_key,
        cafi_freqkey,
        cafi_carrierchargekey,
        cafi_carrierratekey
FROM #QUERYCF
) newdata
on currentdata.cafi_key = newdata.cafi_key

GO
