After upgrade MariaDB from 10.1.15 to 10.3.7 one view stop working:
CREATE OR REPLACE VIEW first_view AS SELECT o.order_pk FROM second_view AS o LEFT JOIN third_view AS d ON o.order_pk=d.order_pk;
Unknown column 'd.order_pk' in 'on clause'
If i change LEFT JOIN to RIGHT JOIN no errors.
I have 10.1.15 in the same cluster and this view works fine.
