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>£" . $row['weekend_price'] . "</td>";
echo "<td>£" . $row['weekday_price'] . "</td>";
echo "</tr>";
}
echo "</table>";
}
else
{
echo "Nothing found.";
}
?>
你会得到错误吗?启用错误报告 – 2012-03-14 01:20:13
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
