使用DbUtils执行sql不能带有引号的参数如何解决?：报错

代码: // 带单引号的字符串，插入到数据库中
  String sql = "INSERT INTO Test(testException) VALUES ('0')";

  QueryRunner qr = DBHelper.getQueryRunner();
  try {
   qr.update(sql);
  } catch (SQLException e) {
   e.printStackTrace();
  }

异常:

java.sql.SQLException: Duplicate entry '0' for key 'PRIMARY' Query: INSERT INTO Test(testException) VALUES ('0') Parameters: []
