mysql中的SQL语法错误

Question

我正在从我的MySQL表中插入值php:

$journey = $_POST['way'];
$from = $_POST['from'];
$to = $_POST['to'];
$dpdt = $_POST['dp_date'];
$rtdt = $_POST['rt_date'];
$fare = $_POST['fare'];
$sql = "insert into tours set " .
        "journey='$journey', from='$from', to='$to', dp_date=CAST('$dpdt' AS DATE), " .
        "rt_date=CAST('$rtdt' AS DATE), fare='$fare'";

在努力echo为$sql我得到输出:

insert into tours set journey='round', from='Aurangabad', to='Kashmir', dp_date=CAST('27-08-2013' AS DATE), rt_date=CAST('21-08-2013' AS DATE), fare='2500'

但我不断得到相同的错误信息:

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 'from=Aurangabad, to='Kashmir', dp_date=CAST('27-08-2013' AS DATE), rt_date=CAST(' at line 1

即使我尝试删除'列名称的值.
我使用相同的语法来插入数据,并且工作正常.
这有什么问题？
为什么MySQL没有为这样可怕的错误提供正确的错误？

Answer 1

`from`='$from', `to`='$to'

FROM 是保留字使用反击围绕它.
