I have both a Java application and a MySQL database on my local machine. My Java application uses ibatis files. What would be the connection url to connect with the MySQL database on my local machine? The name of the database is broker and I have a table called "example."

Use the following code by editing your table name and database name , i guess this would fix your problem .

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

public class CountRows_MySQL {

public static Connection getConnection() throws Exception {
String driver = "org.gjt.mm.mysql.Driver";
String url = "jdbc:mysql://localhost/octopus";
String username = "root";
String password = "root";

Class.forName(driver); // load MySQL driver
Connection conn = DriverManager.getConnection(url, username, password);
return conn;

public static int countRows(Connection conn, String tableName) throws SQLException {
// select the number of rows in the table
Statement stmt = null;
ResultSet rs = null;
int rowCount = -1;
try {
stmt = conn.createStatement();
rs = stmt.executeQuery("SELECT COUNT(*) FROM " + tableName);
// get the number of rows from the result set
rowCount = rs.getInt(1);
} finally {
return rowCount;

public static void main(String[] args) {
Connection conn = null;
try {
conn = getConnection();
String tableName = "myTable";
System.out.println("tableName=" + tableName);
System.out.println("conn=" + conn);
System.out.println("rowCount=" + countRows(conn, tableName));
} catch (Exception e) {
} finally {
// release database resources
try {
} catch (SQLException e) {
