php在MYsql中查询的问题??
我想在数据中根据某个值查询对应的值.例:知道user的值然后显示pwd的值。我在phpamdin里面测试的代码是:

$sql = 'SELECT pwd'
. ' FROM `appdata` '
. ' WHERE user = \[email protected]\' LIMIT 0, 30';
Copy after login

但是加在php文件里面执行总是不成功。

下面是我的代码,怎么修改呢?
 include_once "logindatabase.php";
$cmd = mysql_query(SELECT * FROM appdata WHERE user [email protected]);
$rec = mysql_fetch_array($cmd);
echo $rec[Pwd];
?>
Copy after login

谢谢大家~
------解决方案--------------------
include_once "logindatabase.php";
$cmd = mysql_query('SELECT * FROM appdata WHERE user="[email protected]"');
$rec = mysql_fetch_array($cmd);
//while($rec = mysql_fetch_array($cmd))
echo $rec['Pwd'];
?>
