c# - C# で SSIS を使用して oledbsource から oledbdestination に列をマッピングする方法

Question

からマッピングしたい

OleDbSource (select mFK_Prefix,mFK_Sufix,mElement_Base,mBase_Value,mPeriode_Start,mPeriode_End,mSandi_Pelapor,mOrder from [dbo].[STG_AAKL])

に

OledbDestination(select FK_Prefix,FK_Sufix,Element_Base,Base_Value,Periode_Start,Periode_End,Sandi_Pelapor,Order from [dbo].[TM_AAKL])

ssis inc# を使用して、oledbsource から oledbdestination へのマッピングをプログラムで作成する方法。

完全または私のプログラムについては、この下にあります
