Invalid operation for read only resultset: moveToInsertRow

I try to insert record without using insert query, but I get:
SQLException - Invalid operation for read only resultset: moveToInsertRow.
I've attached my code:
package com.phoenix.demos;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class RandomAccessData {
public static void main(String[] args) {
//Class.forName("oracle.jdbc.driver.OracleDriver");
try {
Connection con = DriverManager.getConnection("jdbc:oracle:thin:#localhost:1521:XE","system","deepa1994");
String query ="Select * from users";
Statement stmt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);
ResultSet rs = stmt.executeQuery(query);
rs.next();
rs.last();
rs.next();
rs.absolute(4);
rs.previous();
rs.relative(-2);
System.out.println(rs.getString(1));
//To add a record - here i get error**
rs.moveToInsertRow();;
rs.updateString(1,"B");
rs.updateString(2, "C");
rs.insertRow();
con.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
I attached output screen to understand error message:

JDBC SQL Server errors: ClassNotFound & Not Suitable Driver Found

I am very new to Java and am simply trying to connect to my MSSQL database and return a list of customers. When I try the JDBC connection, I get a "no suitable driver found" error. When I add a Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver") statement, I get a ClassNotFound error. This seems like it should be a lot easier than it's turning out to be. Please help me either find a suitable driver or how to get access through the Class.forName usage.
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.ResultSet;
import java.sql.Statement;
public class DbConn {
public static String getConnString(){
return "jdbc:sqlserver://localhost\\SQLEXPRESS:1433;database=OhHold;";
}
public static void getConnection() {
try
{
//Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String user = "<USER>";
String pw = "****************";
Connection connection = DriverManager.getConnection(getConnString(), user, pw);
Statement statement = connection.createStatement();
String sql = "select txtCompanyName as company from tblCustomers where intNotActive <> 1";
ResultSet result = statement.executeQuery(sql);
while (result.next()) {
System.out.println(result.getString(1));
}
}

CData JDBC Couchbase Java app connection problem

I can't manage to get this right. I'm not sure of what is wrong. Apparently the connection is ok but can't get the result back of the query.
package probandoCouch;
import cdata.jdbc.couchbase.CouchbaseDriver;
import java.sql.Statement;
import java.util.Properties;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
public class App {
public static void main(String[] args) {
try {
Connection conn = DriverManager.getConnection(
"jdbc:couchbase:User=\"Administrator\";Password=\"Administrator\";Server=\"127.0.0.1\";");
Statement stat = conn.createStatement();
boolean ret = stat.execute("SELECT message FROM greeting WHERE author='foo';");
if (ret) {
ResultSet rs = stat.getResultSet();
while (rs.next()) {
for (int i = 1; i <= rs.getMetaData().getColumnCount(); i++) {
System.out.println(rs.getMetaData().getColumnName(i) + "=" + rs.getString(i));
}
}
}
} catch (SQLException e) {
}
}
}

Can you please remove semicolon(;) from query and try
SELECT message FROM greeting WHERE author='foo';
Updated Query:
SELECT message FROM greeting WHERE author='foo'
With semicolon jdbc will fail with error
java.sql.SQLException: ORA-00933: SQL command not properly ended
In your code you may print the exception to see if any exception is thrown.

Table not found error in eclipse IDE, what to do?

I recently started working on JDBC and I got an Error as Table not found
Table TRIAL not found; SQL statement:
insert into trial values(1,'hello') [42102-73]
Here is my code, also I have already created a table in h2 DB
package trial1;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.Statement;
public class Customer {
public static void main(String[] args) {
Connection conn = null;
try {
conn = DriverManager.getConnection("jdbc:h2:~/test","Aziz", "password");
Statement st = conn.createStatement();
String str = "insert into trial values(1,'hello')";
st.execute(str);
System.out.println("Succes");
}
catch(Exception e) {
e.printStackTrace();
}
}
}
