Early. I am using netCore2.2, corresponding is Pomelo EntityFrameworkCore. MySql version 2.2.6, test is no problem, now. NetCore2.2 upgrading to. NetCore3.1, Pomelo. EntityFrameworkCore. 2.2.6 MySql version upgrade to 3.1.1, is wrong.

Make sure that you set the ServerVersion() accordingly. Take a look at our sample.

Pomelo 3.x uses newer features of newer MySQL/MariaDB versions. And if you don't specify the server version explicitly, the newest one (and MySQL) will be assumed.

Thank you very much for your help so that the problem can be solved quickly.
