mysql - 简单插入语句的问题

Question

我正在处理这段代码，我正在使用一个简单的插入语句，但我不明白为什么它不起作用。如果有人能看到我做错了什么，请告诉我。谢谢!这是我收到的错误:

You have an error in your SQL syntax; check the manual that corresponds 
to your MySQL     server version for the right syntax to use near 'long,comments) 
VALUES (2 ,2012-11-18 21:25:30, 39.3436984, -76.5856958, hh)' at line 1

这是代码:

 mysql_query ("INSERT INTO incidents (emergency_type,date_time,lat,long,comments)  
VALUES  (2 ,$catchDate, $catchLat, $catchLong, $catchDescription)") or die(mysql_error());   
 echo"<br /> Data inserted";

Answer 1

Long 是一个保留字，请尝试用反引号括起来“long”。

快速浏览一下文档就会发现您应该调查 PDO::prepare和 PDO::execute去做这个。您当前的方法似乎容易受到 SQL 注入(inject)的攻击。<​​/p>

我不是 PHP 程序员，但类似:

$db = get a db handle from somewhere
$st = $db->prepare('Insert Into Incidents (emergency_type, date_time, lat, `long`, comments) Values (?, ?, ?, ?, ?)');
$st->execute(array(2 ,$catchDate, $catchLat, $catchLong, $catchDescription));
