大家好我正在写一个不返回任何东西给用户的MySQL查询。我究竟做错了什么?由于该分号MySQL数据库查询什么也没有返回

while($row = $res->fetchRow()); 

它不进入while循环的内容:

<?php 
require_once('MDB2.php'); 
include "mysql-connect.php"; 

// connect to database 

$dsn = "mysql://$username:[email protected]$host/$dbName"; 
$db =& MDB2::connect($dsn); 
if (PEAR::isError($db)) { 
    die($db->getMessage()); 
} 
$table_name="room"; 
$db->setFetchMode(MDB2_FETCHMODE_ASSOC); 

// list the rooms details 

$sql = "SELECT * FROM $table_name"; 
$res =& $db->query($sql); 
if (PEAR::isError($res)) { 
    die($res->getMessage()); 
} 

// display results but if no result has been found then we have to let the user know 

if($res->numRows() > 0) 
{ 
    echo "<table border=1> 
    <tr align='left'> 
    <th scope='col'>Name</th> 
    <th scope='col'>Weekend Price</th> 
    <th scope='col'>Weekday Price</th> 
    </tr>"; 
    while($row = $res->fetchRow()); 
    { 
     echo '<tr align="left">'; 
     echo "<td>" . $row['name'] . "</td>"; 
     echo "<td>&pound" . $row['weekend_price'] . "</td>"; 
     echo "<td>&pound" . $row['weekday_price'] . "</td>"; 
     echo "</tr>"; 
    } 
echo "</table>"; 
} 
else 
{ 
    echo "Nothing found."; 
} 
?>

这仅仅是我的眼睛还是你使用php4? – 2012-03-14 01:20:34

没有错误报告...但是没有任何东西从SQL查询返回,即表是空的。我也使用了正确的字段名称。 – methuselah 2012-03-14 01:22:55

从该行的末尾删除分号。
