You mean a poweshell script that writes to another file? If so, that seems like a waste. I can see having a PoSh that creates the proper BCP format file, which requires no duplication of data on disk.

or better yet powershell that reads file and loads directly to the database (although if this powershell is part of the SSIS package doing it in c# script would even be better)

SSIS task is setup to run the script. The powershell script overwrites the existing ones.

I prefer to using C# to handle the loading and moving files etc. I am more familiar with C# than I am with powershell.

If your any good at all with good ol' DOS (Cmd Line), you can do it all from T-SQL.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

I've been meaning to ask someone and it would seem that you have the experience to answer... have you done a performance comparison between such a PoSh push to the database compared to using BULK INSERT? I have not but I'm curious to know, if you have the time.

No I have not. The BULK INSERT did the job so I stopped there. It is part of SSIS so I will set up the job to run it unattended. So if it takes 5 minutes or 20 minutes it won't matter. I am not sitting there waiting for it.
