You can specify the character set and collation at various levels in MariaDB. You can specify them at the connection level, the server level, the database level, the table level, and the column level.
You can also specify a collation in your queries so that it overrides any collation that has been previously specified at the aforementioned levels.
To set the character set and collation at the database level, use the CREATE DATABASE
statement or ALTER DATABASE
statement (depending on whether you’re creating the database or modifying it).
