When I execute this sql, some setting can't recognized. As the picture shows. And this sql execute in mariadb 5.5 is right.

This is the same issue: https://www.heidisql.com/forum.php?t=24014#p24019

With MySQL and MariaDB 10.1 the server quotes defaults' values. Heidi's parser should be modified to correctly extract non-quoted default values and everything that are going after them.
