USE db_name

From MariaDB 11.7, one can also use



The 'USE db_name' statement tells MariaDB to use the db_name database as the default (current) database for subsequent statements. The database remains the default until the end of the session or another USE statement is issued:

USE db1;
SELECT COUNT(*) FROM mytable;   # selects from db1.mytable
USE db2;
SELECT COUNT(*) FROM mytable;   # selects from db2.mytable

The DATABASE() function (SCHEMA() is a synonym) returns the default database.

Another way to set the default database is specifying its name at mariadb command line client startup.

One cannot use USE DATABASE to a database one has no privileges to. The reason is that a user with no privileges to a database should not be able to know if a database exists or not.
