The next step is to create a database table. Since, MySQL is one of the most popular open-source database systems available today, we shall use it to demonstrate hibernate. We assume that a MySQL instance is running in the host having IP address 172.16.5.81 and the user name and password to access this database are root and nbuser respectively. We also assume that a database test is already created and configured. If it does not exist, create it using the following command at the MySQL command prompt:
mysql> create database test;
Query OK, 1 row affected (0.00 sec)
Now, connect to test database using the following SQL command:
mysql> connect test;
Connection id: 88
Current database: test
Our database is now ready. We can create tables in it. For each class, there should exist a database table which will hold object’s state (attribute values). Since, a Book object will have three fields (b_id, b_titie and b_price), let us create a table tbi_book having three columns using the following SQL command:
create table tbl_book (
no int auto_increment,
primary key (no)
Here no, name and pr columns correspond to id, title and price fields of the Book class respectively.
