Hi,
I have
two tables User and Address. The primary key of the User table is also the
foreign key of Address table.
It is
possible that a user may or may not have address ( Property ) associated with
him and also one user can have more than one address (property). I have two Java
classes which are useful to set and get the values
of the data
members.
public
class User {
private
String UserId ;
private String UserName;
private String Designation;
private String Address;
private String UserName;
private String Designation;
private String Address;
public
String getAddress() { return
Address; }
public
String getDesignation() { return
Designation; }
public
String getUserId() { return UserId; }
public String getUserName() { return UserName; }
public void setAddress(String address) { Address = address; }
public String getUserName() { return UserName; }
public void setAddress(String address) { Address = address; }
public
void setDesignation(String designation) { Designation =
designation; }
public
void setUserId(String userId) { UserId =
userId; }
public void setUserName(String userName) { UserName = userName; }
public void setUserName(String userName) { UserName = userName; }
}
public class
Address
{
private
String UserId;
private String City;
private String State;
private String City;
private String State;
public
String getCity() { return
City; }
public
String getState() { return State; }
public
String getUserId() { return
UserId; }
public
void setCity(String city) { City =
city; }
public
void setState(String state) { State =
state; }
public void setUserId(String userId) { UserId = userId; }
public void setUserId(String userId) { UserId = userId; }
}
The following table
shows the structure of the table.
User
===============
UserId - PrimaryKey
UserName
Designation
Address
Address
===============
UserId -
ForeignKey
City
State
the
following table data is an example data.
User
======================================================
UserId UserName
Designation
Address
1
Abc
S.E City,
New
Yark
2
Xyz
S.E ---
3
Cde
P.M
----
Address
=======================================================
UserId PropertyName PropertyName
1 City New
Yark
1 Country America
2
--
---
3
City
NewYark
4 City London
When I am trying to get the data from both the tables
using the following Query
select * from User, Address where User.UserId =
Address.UserId
the result
is
1, Abc ,
S.E
1, City, New
Yark
1, Country, America
Now my
requirement is to get the data from both the tables and store them as User
Object.
Can any one specify
1. IBatis SQL Mappings for the tables.
2.
SQL Qury to get the data from both the tables and store it in User
Object.
regards,
rambabu
