Which parameters I should use to change connection collation to MySQL?
IIRC, this can be done with a query, or updating your my.cnf
[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake
Or, run this to set your specific collate:
ALTER DATABASE <database_name> CHARACTER SET utf8 COLLATE utf8_unicode_ci;
More info here:
and
It’s a legacy database and can’t alter it.
DROP TABLE table_name;
should help with that
