因此，我编写了一个 PHP 脚本，以便将我以前的 MySQL 数据库升级到具有新关系和内容的新数据库。一切似乎都运行良好，直到我注意到我的新数据库中缺少一些条目。我的旧数据库显示该表的 322 条记录，而我的新鞋仅显示 95 条记录。因此，由于有一些条目，我不知道问题出在哪里，谁能帮助我？

这是我的代码，我只在具有 bigint、varchar、double 和 float 的表 POIS 中遇到此问题：

<?
include("mysql.class.php");


$db_old = new mysqli("localhost", "root", "admin", "smarturbia_old");

既然两个数据库都驻留在同一台主机上，为什么不简单地使用 SQL 将它们复制过来呢？大致取自您的代码：

INSERT INTO SMARTURBIA.cities 
SELECT SMARTURBIA_OLD.cities.*,catagories.name 
  from SMARTURBIA_OLD.cities, SMARTURBIA.CATEGORIES 
 WHERE cities.path=categories.name;

和

INSERT INTO SMARTURBIA.kmz SELECT * FROM SMARTURBIA_OLD.kmz;

和

INSERT INTO SMARTURBIA.pois SELECT * FROM SMARTURBIA_OLD.pois;

等等 ：）

这样，如果所有行都已迁移，您可以立即查看（受影响的行数）。
