Custom table in database

[MaxDau]

Is it possible to create an additional table in the database or is there a risk that the table will be deleted during an update or rebuild?

As nobody have respond, i. will try :

no, no issue in upgrade..
but you can not use ORM or any other (certainly 100%) EspoCrm function to access to this table.

But maybe, https://docs.espocrm.com/administrat.../#hard-rebuild can delete table.. (not verified the command code), but hard-rebuild is not for everyone to use as advice by Yuri.

I use custom table and retrieve data with sqlExecutor by running plain sql. No issues for about a month since I implemented this logic.

Tables are not removed on hard rebuild, as stated in the docs.
