External forms: direct connection to mysql

I have the following set-up:

A) a msqlv database with all tables
B) an odb file that links to A
C) an external form (ie a writer document) that refers to B

That works fine but the odb-file in B only serves as a proxy between A and C.

Is there a way to directly connect from an external form to a mysql database

Thanks for any hints.

Data Sources are only accessible to registered databases. Therefore, the .odb is necessary for registering it. I wouldn’t call a Writer document an external form since there is a lot of interconnectivity in LibreOffice. For example, Base forms are little more than Writer documents.

OK, thanks for your answer.
