"The database is missing some indexes." and "Some columns in the database are missing a conversion to big int." with phpmyadmin and-or CRON job (can't use occ command in shared hosting)

Hello everybody,
First of all I wish you all very happy celebrations! :partying_face::tada::santa::confetti_ball::snowman_with_snow:

I turn to you regarding the new alerts in my configuration since the update from 17.0.1 to 17.0.2:
β€œSome columns in the database are missing a conversion to big int. […]”
mounts.storage_id
mounts.root_id
mounts.mount_id

I don’t know how to identify the characteristics to make the necessary sql commands myself, if someone can help me?

I know it should look something like this:

ALTER TABLE `???` MODIFY `mounts.storage_id` bigint ???;
ALTER TABLE `???` MODIFY `mounts.root_id` bigint ???;
ALTER TABLE `???` MODIFY `mounts.mount_id` bigint ???;

But I don’t know how to identify in which table (oc_filecache, oc_mimetypes, oc_storages, …) and what value to configure for each column (NOT NULL DEFAULT β€˜0’ or NOT NULL AUTO_INCREMENT)?

In advance thank you for your help and all wishes of happiness and good health to all :metal::kissing_heart::hugs:
