Is copyleft superimposed on the mysql protocol?

Question

MySQL

I am developing a comet service that provides Saas services and instead of writing an api for every more or less popular language, I want to implement support for the mysql protocol so that I can work with my service using the mysql client.
By analogy with how Sphinx works on the mysql protocol using SphinxQL, I want to create my own CometQL.
Thus, I would cover support for at least 14 languages.
But I am concerned about the legal side of this issue. mysql under gpl like Sphinx and I'm developing a proprietary service.
If I plan to use the mysql protocol will it not impose gpl restrictions on my project?

Answer 1

MySQL is licensed under the GPL. So, if you do not use MySQL source code in your product and do not link its static libraries, then you can use any license.

Answer 2

Not in theory unless you use mysql code.

Answer 3

In theory, he will impose, i.e. you must distribute your software with source code.
We did not bother and switched to PostgreSQL.

Make one site. What I saw on the link is a tin. Google will immediately drop this in the search results.
