In other words, if you try to create a database that already exists with the if not exist option, MariaDB will do nothing.įinally, optionally specify a character set and collation for the new database. Third, use the if not exist option to conditionally create a database if it does not exist. ![]() Note that MariaDB has supported the or replace clause since version 10.1.3.
