Question

this is my code snippet,

import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Statement;

public class Delete
{
    public static void main(String args[])
    {
        try
        {
            Class.forName("com.mysql.jdbc.Driver");

            Connection con = DriverManager.getConnection("mysql:jdbc://localhost:3306/raja","root","459805");
            Statement stmt=con.createStatement();
            int count=stmt.executeUpdate("DELETE GENNU WHERE USER_ID=3;");
            if(count>0)
                System.out.println(" Ok Deletion done");
        }
        catch(ClassNotFoundException e)
        {
            System.out.println(e.getMessage());
        }
        catch(SQLException e)
        {
            System.out.println(e.getMessage());
        }
    }
}

and when I execute it , i got like this.

Answer 1

actually you have an error in your DELETE statement, you lack FROM keyword. it should be

DELETE FROM GENNU WHERE USER_ID=3

see the error, it’s pointing on DELETE.

UPDATE 1

try, jdbc:mysql not mysql:jdbc

Class.forName("com.mysql.jdbc.Driver");
connect = DriverManager.getConnection("jdbc:mysql://localhost:3306/raja"
              + "user=root&password=459805");
