Updating spatial data USING JAVA

Question

I want to update spatial data using java.Does anyone know how can i do this;;;
for example i have created the following table.
CREATE TABLE customers (
customer_id NUMBER,
last_name VARCHAR2(30),
first_name VARCHAR2(30),
street_address VARCHAR2(40),
city VARCHAR2(30),
state_province_code VARCHAR2(2),
postal_code VARCHAR2(9),
cust_geo_location SDO_GEOMETRY);
HOW CAN I UPDATE THE FIELD:cust_geo_location,
WHICH TYPE IS: SDO_GEOMETRY;;;;;
I wrote a programm in java, which updates the FIELD CUSTOMER_ID.
( rset.absolute(3);
rset.updateInt("CUSTOMER_ID",2222 );
CUSTOMER_ID = rset.getInt("CUSTOMER_ID");
rset.next();
rset.updateRow(); ).
---------- THE FULL JAVA PROGRAMM
import java.sql.*;
import java.io.*;
import java.util.Date;
public class update{
public static void main (String args [])
throws SQLException, IOException
System.out.println ("Loading Oracle driver");
try {
Class.forName ("oracle.jdbc.driver.OracleDriver");
catch (ClassNotFoundException e)
System.out.println ("Could not load the driver");
e.printStackTrace ();
System.out.println ("Connecting to the local database");
try{
Connection conn =
DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:XE", "sp", "spgianna");
Statement stmt = conn.createStatement (ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_UPDATABLE);
// String LAST_NAME,FIRST_NAME ;
int CUSTOMER_ID ;
ResultSet rset = stmt.executeQuery("SELECT CUSTOMER_ID FROM CUSTOMERS");
/* while ( rset.next() ) {
CUSTOMER_ID = rset.getInt("CUSTOMER_ID");
LAST_NAME = rset.getString("LAST_NAME");
FIRST_NAME = rset.getString("FIRST_NAME");
System.out.println( CUSTOMER_ID+""+LAST_NAME + " " +FIRST_NAME);
rset.absolute(3);
rset.updateInt("CUSTOMER_ID",2222 );
CUSTOMER_ID = rset.getInt("CUSTOMER_ID");
rset.next();
rset.updateRow();
System.out.println(CUSTOMER_ID);
catch(SQLException sqle) {
System.out.println("SQL Exception encountered: " );
} catch(Exception e) {
System.out.println("Unexpected Exception: " );
HOW CAN I UPDATE THE FIELD:cust_geo_location,
WHICH TYPE IS: SDO_GEOMETRY;;;;;;;;;;;;;;

Hi Guys,
Dont forget to close your stmt and connection after execution
Use this as a template if you like:
try{
     /**make connection**/
     ServerConnection sc = new ServerConnection();
Statement stmt = sc.conn.createStatement();
/**create statement & execute**/
String insertstmt = "insert into .......";
//execute
stmt.execute(insertstmt);
/**Close and catch exception**/
stmt.close();
sc.conn.close();
catch(SQLException sqlE){
     sqlE.printStackTrace();
     System.out.println(sqlE.getMessage());
As for the string "insertstmt" itself, this is where your standard SQL statement goes
So get it working using a standard SQL editor first, then copy and paste it in to this string variable. The string should be a series of concatenated strings and variables to recreate the SQL atatement in Java. For example
the SQL statement:
insert into Mytable(SESSIONID, TIME1) values ('300', '4.45pm' );
assuming the values are stored in variables called 'sessionnumber' and 'time'
will become
String stmt =
"insert into Mytable(SESSIONID, TIME1) values ('"+sessionnumber+"', '"+time+"')";
Hope this helps.
E
Ps. Do a system.out.println after you create the stmt. The statement printed out to the console should be a valid SQL statement that you can use in your editor. (minus the ;)
...keep working on the string until you can do this.
