When configuring the ODB examples you can use --with-mysql-* options
(run configure --help to see the list of them) to specify the MySQL
user, password, and database that the examples should use.

Running examples as the root MySQL user is a really bad idea. Instead,
I suggest that you use a different database user. Here is how you can
create a separate user and database for ODB:

Login to mysql as root and then run these SQL statements:

CREATE USER odb_test@'%';
CREATE USER odb_test@'localhost';
GRANT ALL PRIVILEGES ON odb_test.* to odb_test@'%';

This will create a new user called odb_test and a new database
also called odb_test. The odb_test user will have no password.

Once this is done, configure the ODB examples like this:

./configure --with-database=mysql --with-mysql-user=odb_test \
--with-mysql-password=no --with-mysql-db=odb_test ...

Also note that here we assume that you run the examples on the
same machine as the the MySQL server itself. If that's not the
case, then use the --with-mysql-host option to specify the
remote MySQL host.
