CONMISANMA的正确答案——PreparedStatement获取完整SQL

测试系统：DEEPIN LINX 15.6

测试软件：NETBEANS 8.2 & arduino 1.8.4 

JDK版本：1.8

 

PreparedStatement preparedStatement = connection.prepareStatement("select * from ?");

preparedStatement.setString(1,"USER");

System.out.println(preparedStatement.toString());

  输出：select * from USER

没错，什么根据问号填充参数函数全都不如这一个 toString() 好用！
