Suppose currently we are using a tutorial database so it would be the default MySQL database for subsequent queries. Now, with the help of USE db_name statement, we can change the default database to other given database subsequent queries.
mysql> USE Sample Database changed
The database has been changed to Sample from the tutorial. To verify this we can run the following command −
mysql> select database(); +------------+ | database() | +------------+ | sample | +------------+ 1 row in set (0.00 sec)
