Answer 1

Apart from creating the table hibernate_sequence which has a column next_val you can also set quarkus.hibernate-orm.database.generation = drop-and-create. Note this will delete all the record in you database.

Answer 2

For me, what was causing this error was the wrong version of the MySql.Data library.

I had a version 6.9.6.0 defined in the web.config and yet the actual referenced version was older.

I just commented out :

     <system.data>
      <DbProviderFactories>
      <remove invariant="MySql.Data.MySqlClient" />
        <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.9.6.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
     </DbProviderFactories>
   </system.data>
