所以我编写了一个PHP脚本，以便将我以前的MySQL数据库升级到一个新的关系和新东西。一切似乎工作正常，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，而我的新表只有95条。所以，由于有些条目成功，我不知道问题出在哪里可以帮助我吗？
这是我的代码，我只在包含bigint，varchar，double和float的表POIS中遇到此问题：

由于两个数据库都位于同一主机上，为什么不简单地使用SQL复制它们？从你的代码中轻松取出：
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;
依此类推:)）
这样，如果已迁移所有行，您可以立即看到（受影响的行数）。

所以我想出来了，问题是我的特殊角色，所以我mysqli real_escape_string（）来解决我的问题。不管怎样，谢谢你们。
