   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;

 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 void setDesignation(String designation) {  Designation =
designation; }

 public void setUserId(String userId) {  UserId = userId; }

 public void setUserName(String userName) {  UserName = userName; }


public class Address

 private String UserId;
 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; }


The following table shows the structure of the table.

UserId  - PrimaryKey

UserId - ForeignKey

the following table data is an example data.

UserId                UserName               Designation

    1                    Abc                        S.E
City, New Yark                         
    2                    Xyz                         S.E
    3                    Cde                        P.M

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.
