Preparing table for HQL Examples


In this lesson we will create insurance table and populate it with the data. We will use insurance table for rest of the HQL tutorial.

To create the insurance table and insert the sample data, run the following sql query:


/*Table structure for table `insurance` */

drop table if exists `insurance`;

CREATE TABLE `insurance` (
`ID` int(11) NOT NULL default '0',
`insurance_name` varchar(50) default NULL,
`invested_amount` int(11) default NULL,
`investement_date` datetime default NULL,
PRIMARY KEY (`ID`)
) TYPE=MyISAM;

/*Data for the table `insurance` */

insert into `insurance` values (1,'Car Insurance',1000,'2005-01-05 00:00:00');
insert into `insurance` values (2,'Life Insurance',100,'2005-10-01 00:00:00');
insert into `insurance` values (3,'Life Insurance',500,'2005-10-15 00:00:00');
insert into `insurance` values (4,'Car Insurance',2500,'2005-01-01 00:00:00');
insert into `insurance` values (5,'Dental Insurance',500,'2004-01-01 00:00:00');
insert into `insurance` values (6,'Life Insurance',900,'2003-01-01 00:00:00');
insert into `insurance` values (7,'Travel Insurance',2000,'2005-02-02 00:00:00');
insert into `insurance` values (8,'Travel Insurance',600,'2005-03-03 00:00:00');
insert into `insurance` values (9,'Medical Insurance',700,'2005-04-04 00:00:00');
insert into `insurance` values (10,'Medical Insurance',900,'2005-03-03 00:00:00');
insert into `insurance` values (11,'Home Insurance',800,'2005-02-02 00:00:00');
insert into `insurance` values (12,'Home Insurance',750,'2004-09-09 00:00:00');
insert into `insurance` values (13,'Motorcycle Insurance',900,'2004-06-06 00:00:00');

Above Sql query will create insurance table and add the

ID insurance_name invested_amount investement_date
1 Car Insurance 1000 2005-01-05 00:00:00
2 Life Insurance 100 2005-10-01 00:00:00
3 Life Insurance 500 2005-10-15 00:00:00
4 Car Insurance 2500 2005-01-01 00:00:00
5 Dental Insurance 500 2004-01-01 00:00:00
6 Life Insurance 900 2003-01-01 00:00:00
7 Travel Insurance 2000 2005-02-02 00:00:00
8 Travel Insurance 600 2005-03-03 00:00:00
9 Medical Insurance 700 2005-04-04 00:00:00
10 Medical Insurance 900 2005-03-03 00:00:00
11 Home Insurance 800 2005-02-02 00:00:00
12 Home Insurance 750 2004-09-09 00:00:00
13 Motorcycle Insurance 900 2004-06-06 00:00:00
14 Motorcycle Insurance 780 2005-03-03 00:00:00
In the future lessons we will use this table to write
different HQL examples.
