Cannot bulk load because the file could not be opened. Operating system error code (null).

Hello everbody,

I have a Azure SQL Database a side of that that I'm working on a Windows 10 with vSQL Server Management Studio 15.0.18386.0

The last week I imported some data successfully with bulk method.

Today the execution of the same query launched this error ;

"Cannot bulk load because the file could not be opened C:****. Operating system error code (null)."

After this I searched about and found that people was having trouble because the file was on read only.

In my case I didn't set any file to read only anyways I tried some things:

-Set total control permission for the user that MMSS uses behind.

-Run as admin the CMD and connect trought sqlcmd to the server and launch the same querry.

-Moved the files to another device and change the path of the query

I don't know where the error can be. In this gap of time, I only installed a secure software. Beside that nothing more.

Maybe this is not the right forum to ask this, tell me if that's the case. But I found someone with the same asking a simila error.

Thanks in advance

    I think I found one thing that will explain at least why It is not working.

    On this doc about the bulk command.

    This is shown:


    Anyway this does not resolve why the week before It worked.

    I did not have at anytime a blob where to upload the files from.

    I insist again, the paths were local and I saved them exactly as they worked because I knew I would reuse it again.

    Hi @Alex Blanes ,

    Yes. You find the correct doc.
    Azure SQL Database only supports reading from Azure Blob Storage. File Storage is not supported.
    So i recommend you to use Blob Storage.
