Syntax

USE db_name

Description

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() and SCHEMA() functions returns the default database.

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