我正在尝试通过从 https://github.com/ascendix/salesforce-jdbc获得的 JDBC 驱动程序与 Salesforce 建立连接

我已经在 SQLWorkbench 工具中设置了这个驱动程序。连接成功。在此处输入图像描述但是，当我执行任何查询（例如SELECT Id from Account）时，它会失败并出现错误

详细日志：

我检查了数据库资源管理器-> 对象选项卡有一个所有对象的列表（帐户、联系人等）但是当我单击数据选项卡检查数据时，也出现了上述相同的错误。

所以我什至尝试在eclipse中编写JDBC代码，那里也连接成功，但是在执行代码时我得到了以下错误

 Connected to Salesforce.
com.ascendix.jdbc.salesforce.ForceConnection createStatement
INFO: createStatement
java.lang.NullPointerException
    at SFJDBC.main(SFJDBC.java:77)

参考代码：

try 
    {

        final String UserName = "user";

        final String Password = "password";

        String dbURL = "jdbc:ascendix:salesforce://login.salesforce.com";
        String dbUsername = "xyz";
        String dbPassword = "xyz";

        java.util.Properties connProperties = new java.util.Properties();
        connProperties.put(UserName, dbUsername);
        connProperties.put(Password, dbPassword);

        Class.forName("com.ascendix.jdbc.salesforce.ForceDriver");
        Properties connectionProps = new Properties();
        connectionProps.put(UserName,dbUsername);
        connectionProps.put(Password,dbPassword);
        Connection connection = DriverManager.getConnection(dbURL, connectionProps);
        System.out.println(connection.toString());

        if(!connection.isClosed())
        {
            System.out.println("Connected to Salesforce.");

            Statement stmt = null;
            ResultSet rs = null;
            stmt = connection.createStatement();
            rs = stmt.executeQuery("SELECT Id FROM ACCOUNT");
            while (rs.next()) {
                System.out.println(rs.getString(1));
            }

        }   

    } 



    catch (Exception e) {
        e.printStackTrace();

    }

我更关心让驱动程序为 SQL Workbench 工作。任何解决此问题的帮助将不胜感激。

**** 更新 ****

感谢@Mark Rotteveel 根据他的建议对代码进行了更改并发布代码成功。但也需要让这个驱动程序在 SQL Workbench 中工作。

PreparedStatement preparedStatement = connection.prepareStatement("SELECT Id FROM Account limit 3");
            preparedStatement = connection.prepareStatement("SELECT Id FROM Account limit 3");
            ResultSet resultSet = preparedStatement.executeQuery();
            while (resultSet.next())
            {
                 System.out.println(resultSet.getString(1));
            }
