在MySQL數據庫中缺少數據

Question

因此，我編寫了一個PHP腳本，以便將我以前的MySQL數據庫升級到具有新關係和新功能的新數據庫。一切似乎都工作正常，直到我注意到我的新數據庫中缺少一些條目。我的舊數據庫顯示了該表的322條記錄，而我的新鞋只有95條。因此，由於有些條目是成功的，所以我不知道問題出在哪裏？

這裏是我的代碼，我只有在表POIS這個問題有BIGINT，VARCHAR，雙和float：

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


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

Answer 1

所以我想通了，問題是我的特殊字符，所以我mysqli real_escape_string（）來解決我的問題。無論如何，謝謝你們。

Answer 2

由於這兩個數據庫駐留在同一臺主機上，你爲什麼不只需使用SQL複製它們？從您的代碼鬆散採取：

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:)

這樣的話，你可以立即看到（受影響的行數）如果所有行都已被遷移。
