postgres数据库使用dbutils

每次都报this method is not yet implemented以及SQL Exception图片说明
求大神帮助解决啊。。。
package com.ezio.mvc.mar4.test;

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

import javax.sql.DataSource;

import org.apache.commons.dbutils.QueryRunner;
import org.junit.Test;

import com.ezio.mvc.mar4.db.JdbcUtils;
import com.mchange.v2.c3p0.ComboPooledDataSource;

public class TestConnection {

@Test
public void test() throws SQLException {
    Connection conn = JdbcUtils.getConnection();
    /*String sql = "INSERT INTO customers(name, address, phone) VALUES(?, ?, ?)";
    PreparedStatement pstm = conn.prepareStatement(sql);
    pstm.setString(1, "123");
    pstm.setString(2, "asdfasdfasf");
    pstm.setString(3, "abc");
    pstm.executeQuery();*/
    QueryRunner queryRunner = new QueryRunner();
    String sql = "INSERT INTO customers(name, address, phone) VALUES(?,?,?)";
    queryRunner.update(conn, sql, 10, 32, 63);
}

}
这个是我的源码，数据库连接没有问题，我本人已经测试过。不管我怎么搞，都无法执行操作啊。

先不用参数试试看，检查你的表名、字段是否正确。
