the MySQL command line client directly (including the name of the

database to operate on). The MySQL user used has to have enough

privileges to do all necessary operations (among others CREATE, ALTER,

DROP, UPDATE, INSERT, DELETE).

You might need to enter the mysql password multiple times if you

specify the -p option.
