The database is created only once but it is necessary to select it each time we begin a MySQL
session. It can be done with the help of USE db_name statement on MySQL command line tool.
mysql> Use Query; Database changed
It shows that we are now using query database.
We can also select the database while invoking the MySQL from Windows command line. It can be done with the help of the following command −
C:\Program Files\MySQL\bin>mysql -u root -p query Enter password: *****
Here, query is the name of the database we are going to use for current MySQL session
