          This view provides the current
          sys schema and MySQL server
          versions.
Note
            As of MySQL 8.0.18, this view is deprecated and subject to
            removal in a future MySQL version. Applications that use it
            should be migrated to use an alternative instead. For
            example, use the VERSION()
            function to retrieve the MySQL server version.
          The version view has these
          columns:
- sys_version- The - sysschema version.
- mysql_version- The MySQL server version.
