Connection to MySQL by using mysql-connector.jar file and displaying data

MySQL Configuration using mysql-connector.jar file

After configuration of mysql-connector.jar file, you can try this code.

In our script we used following values.

Database Name = my_tutorial
User id = root
Password = my_password ( use your password )

Table name = student

Query = "SELECT * FROM student"

To get details of student table you can check here.

MySQL student table dump

We will use the above details to connect and get the data from MySQL table.

import java.sql.*;
public class mysql_connect1 {
public static void main(String[] args) throws Exception
{
	String url = "jdbc:mysql://localhost:3306/my_tutorial";
	String uname = "root";
	String pass = ""; // your password 
	String query = " SELECT * FROM STUDENT ";
	
	Class.forName("com.mysql.jdbc.Driver");
	Connection conn = DriverManager.getConnection(url,uname,pass);
	Statement st= conn.createStatement();
	ResultSet rs= st.executeQuery(query);
	
	rs.next();
	System.out.println(rs.getString("name"));
	
	rs.next();
	System.out.println(rs.getString("name"));
	
	st.close();
	conn.close();
}	
}

The output is here

This output has shown us two records ( names of two student ) .
Now we will use the ResultSet to display all the records of our student table.

import java.sql.*;
public class my_connect {
	public static void main(String args[]) 
	{  
	try{  
	Class.forName("com.mysql.jdbc.Driver");  
	Connection con=DriverManager.getConnection(  
	"jdbc:mysql://localhost:3306/my_tutorial","root","password_here");  
	Statement st=con.createStatement();  
	ResultSet rs=st.executeQuery("SELECT * FROM STUDENT"); 
		
	while(rs.next())  
	System.out.println(rs.getInt(1)+" "+rs.getString("name"));  
		
	con.close();  
	}catch(Exception e){ System.out.println(e);} 
		
	}
}

Output ( all records )
