Creating a DOMAIN in MySQL or MariaDB?

As far as I know, DOMAINS cannot be created in MySQL. Is there any disadvantage for that? Is there something to be used instead of using CREATE DOMAIN?

No, check constraints are supported by MariaDB. Domains are user defined datatypes. The domain mechanism allows you to put constraints on the datatype instead of having to put constraints on every single column where the specific datatype is being used.
