Description
Have trigger functionality for data "change log" collecting in separate table.
Trigger compares OLD. with NEW. and changes are inserted into H table.
This works correctly with MySQL (5.6, 8.0 atleast).
In MariaDB this does not work.
Script provided shoud produce 4+5+4 rows in H table, and should not end up with error
Unknown column 'I4' in 'field list'
Now works only middle part of trigger - with removed WHERE clause.
