Insert Blob from large file

[Rossati Giovanni]

Hello

I am writing a Python automa for upload documents. When the documents are larger than about 1,5 M the upload fail.
I think to work around by uploading chunks, and this can works but usin CONCAT function I must set the internal variable @@session.max_allowed_packet to a sufficent value.

There is an alternative to CONCAT, somethings like a function APPEND_CHUNK wich simple append data?

Thanks
