MySQLSyntaxErrorException

Question

I've just started to learn MySQL and JDBC.

I created a table called testdb using phpmyadmin. Table just has 2 columns called first and last. When I am trying to connect the database from my java class, I get MySQLSyntaxError. However I could not figure it out.

Here is my class:

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

public class Main {

    public static void main(String[] args) throws ClassNotFoundException, SQLException {
        String url = "jdbc:mysql://localhost:3306/testdb";

        //Accessing driver from the JAR file.
        Class.forName("com.mysql.jdbc.Driver");

        //Creating a variable for the connection "con"
        Connection con = DriverManager.getConnection(url,"root","password");

        //Here is the query
        PreparedStatement statement = con.prepareStatement("select * from name");

        //Execute query
        ResultSet result = statement.executeQuery();

        while(result.next()) {
            System.out.println(result.getString(1) + " " + result.getString(2));
        }


    }

}

And here is the exception:

MySQLSyntaxErrorException: Table 'testdb.name' doesn't exist

error is pretty much descriptive. There is not table with name "name" in testdb schema.

I created a table called testdb using phpmyadmin.

If you have created table testdb then it should be select * from testdb. isn't it?

You've created a table named testdb therefore your query should be

select * from testdb

not select * from name

you should really check your stacktraces.
