sorry, I still can't reproduce the issue, even using the same stock
Emacs and org-mode from Debian 9 as you do.

Could you _attach_ the emacs init file and the org-mode file which
shows the issue?  (so I can simply start “emacs -Q -l sqlite.emacs
sqlite.org” and then press C-c C-c inside the sqlite code to see the
issue?

My emacs init has grown over the years and it includes a lot of others. I should try to create

 

a clean one.

I think I am almost there. Is it possible to create a memory database with org-babel instead of a file based

 

one. That would make more transparent I think.
