Cassandra jdbc connection with Authentication

I am trying to connect to the Cassandra using cdata jdbc connector. However, I cannot find how to provide username and password in connection url. Here are my java code.
package com.dremio.exec.store.jdbc.conf;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
public class TestConnection {
public static void main(String[] args) throws Exception {
Connection con = null;
Class.forName("org.apache.cassandra.cql.jdbc.CassandraDriver");
con = DriverManager.getConnection("jdbc:cassandra://localhost:9160");
String query = "SELECT * FROM emp";
Statement stmt = con.createStatement();
ResultSet result = stmt.executeQuery(query);
while (result.next()) {
System.out.println(result.getString("emp_id"));
System.out.println(result.getString("emp_name"));
System.out.println(result.getString("emp_city"));
}
con.close();
}
}
Currently, I am providing url as without Authentication. How can i provide username and password there.

CData's (poor) documentation lists User and Password as available properties to add to a JDBC connection string. You can add these with your username and password to authenticate:
con = DriverManager.getConnection(
"jdbc:cassandra://localhost:9160;User=ayush;Password=yourpwd");
You could also add them as properties, as detailed in their Connecting From Code examples:
Properties prop = new Properties();
prop.setProperty("Port","9042");
prop.setProperty("Server","127.0.0.1");
prop.setProperty("User","ayush");
prop.setProperty("Password","yourpwd");
Connection conn = DriverManager.getConnection("jdbc:cassandra:",prop);
Also, unless you're using an old Cassandra cluster or 3.x cluster with Thrift enabled, 9160 isn't going to work. In fact, the Thrift project hasn't had a pull request in a few years now, so I would suggest moving away from it and using the native binary protocol on 9042.

Login failed for user 'DESKTOP-6U7R1AC\Amit'

I want to connect my sql server database with java. here is the code I have
package myPackage;
import java.beans.Statement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
public class Test1 {
public static void main(String[] args) throws SQLException, ClassNotFoundException {
// TODO Auto-generated method stub
String url = "jdbc:sqlserver://DESKTOP-6U7R1AC\\SQLEXPRESS;databaseName=sample1;";
String uname="DESKTOP-6U7R1AC\\Amit";
String pass="";
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection conn = DriverManager.getConnection(url,uname,pass);
System.out.println("command completed sucessfully");
Statement stmt =(Statement) conn.createStatement();
String query ="SELECT * FROM tblPerson";
ResultSet rs =((java.sql.Statement) stmt).executeQuery(query);
while(rs.next()){
System.out.println(rs.getInt(1) +" "+rs.getString(2) +" "+rs.getString(3) );
}
}
}
Please note that
I am using Microsoft SQL server management studio 18.
I have added the mssql-jdbc-8.4.1.jar in the build path.
my SQL server details
server type: Database Engine

The problem is solved now. here is the correct code for...
package myPackage;
import java.sql.Statement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
public class Test1 {
public static void main(String[] args) throws SQLException, ClassNotFoundException {
// TODO Auto-generated method stub
String url = "jdbc:sqlserver://DESKTOP-6U7R1AC\\SQLEXPRESS;databaseName=sample1;integratedSecurity=true";
String uname="DESKTOP-6U7R1AC\\Amit";
String pass="";
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection conn = DriverManager.getConnection(url,uname,pass);
System.out.println("command completed sucessfully");
Statement stmt = conn.createStatement();
String query ="SELECT * FROM tblPerson";
ResultSet rs =((java.sql.Statement) stmt).executeQuery(query);
while(rs.next()){
System.out.println(rs.getInt(1) +" "+rs.getString(2) +" "+rs.getString(3) );
}
}
}
The changes I did.
fist set the integratedSecurity=true and then I was getting an error saying that sqljdbc_auth.dll is not found in java.library.path . Then I added the sqljdbc_auth.dll in java.library.path and it worked.

Can anyone please help me fix this.
I am giving all credentials correctly , even then it says Access Denied.

It is possible that MySQL is only setup to accept connections on local host. Can you update the grant statement to use 'user#%'

String USERNAME = System.getEnv("OPENSHIFT_MYSQL_DB_USERNAME");
String PASSWORD = System.getEnv("OPENSHIFT_MYSQL_DB_PASSWORD");
String DB_NAME = System.getEnv("OPENSHIFT_APP_NAME");
String FORNAME_URL = "com.mysql.jdbc.Driver";
String URL = "jdbc:"+System.getEnv("OPENSHIFT_MYSQL_DB_URL")+ DB_NAME;
Connection m_connection = DriverManager.getConnection(URL , USERNAME , PASSWORD);
Use it like this.Openshift will not relay on static ip so they will not accept your connection via that ip or the localhost. Also if you are trying it on your local server rather that deploying it on openshift you have to use ssh tokens for the connection and i think it's not allowed.

Android-MysqlConnectivity in eclipse

I am new to android, So i need a basic knowledge,How to connect to the database and Select some of the values from it.
These are all the following steps i have already completed by watching and reading some online tutorials.
Created a New ANDROID Project Named And2.
Created a New JAVA Project named MYSQLConnection which is used to store the database connection.
I have Downloaded mysql-connector-java-5.1.34 file Online and added it.
I have attached the Screen Shot the total overview of my eclipse.
Now i just needed to access the database in And2 and Write a Simple Select Query So that i can make sure that connection is created.
Shown below is the Java file for DB Connection.
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Connection;
import java.sql.Statement;
import com.mysql.jdbc.*;
//import com.mysql.jdbc.Connection;
//import com.mysql.jdbc.Statement;
public class Main {
public static void main(String[] args) throws Exception
{
Class.forName("com.mysql.jdbc.Driver");
try
{
String connectionUrl = "jdbc:mysql://localhost:3306/testdatabase";
String connectionUser = "root";
String connectionPassword = "12345";
Connection conn = DriverManager.getConnection(connectionUrl, connectionUser,
connectionPassword);
//Statement stmt = conn.createStatement();
// ResultSet reset = stmt.executeQuery("select * from TableName");
//
// //Print the data to the console
// while(reset.next()){
// Log.w("Data:",reset.getString(3));
//
// }
}
catch ( SQLException err )
{
System.out.println("Database connection failed");
}
}

Any Help appreciated.

Connect to MySQL using JDBC driver through a proxy [duplicate]

This question already has an answer here:
MySQL Connect via proxy in Java
(1 answer)
Closed 2 years ago.
In Java, I would like to make a connection to a MySQL server which is on the web from a client computer that is behind a http proxy. I have read few solutions some say http tunnelling might work and some suggest a very old link from oracle which is not available anymore. So the question is:
How can we connect to a MySQL server from a computer which is behind a http proxy?

You can try the following code and see if it works. It worked for me over TCP
package indika.jdbc.connectivity;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.Properties;
public class ConnectOverProxy {
public static void main(String[] args) {
new ConnectOverProxy();
}
public ConnectOverProxy() {
try {
Class.forName("com.mysql.jdbc.Driver");
Connection conn = null;
Properties info = new Properties();
//info.put("proxy_type", "4"); // SSL Tunneling
info.put("proxy_host", "[proxy host]");
info.put("proxy_port", "[proxy port]");
info.put("proxy_user", "[proxy user]");
info.put("proxy_password", "[proxy password]");
info.put("user", "[db user]");
info.put("password", "[db pass word]");
conn = DriverManager.getConnection("jdbc:mysql://[db host]/",info);
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("Select NOW()");
rs.next();
System.out.println("Data- " + rs.getString(1));
rs.close();
stmt.close();
conn.close();
} catch (SQLException er) {
er.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
}
Also look at "http://www.idssoftware.com/jdbchttps.html", However I have not used this personally.
