I woud like to make join between tables in different collations. But it throws me an error #1267 - Illegal mix of collations (utf8_unicode_ci,IMPLICIT) and (utf8_slovak_ci,IMPLICIT) for operation '='
SELECT `orders`.* from `orders`
JOIN `users` ON `orders`.`users_id` = `users`.`id`
JOIN `acl_users` ON `acl_users`.`email` = `users`.`email`
AND `acl_users`.`id` != `users`.`id`
How can I solve this issue?
