Question

可能重复：
mysql_fetch_array() expects parameter 1 to be resource, boolean given in select

这是我得到的错误：警告：mysql_fetch_array（）期望参数1是资源，在.....中给出布尔值

我试图找出错误，但我无法做到......有人可以帮我看看吗？

提前致谢。

问题解决了。

感谢大家回复了我的问题，这是我的错误：

注意：.....中的'order clause'中的未知列'id'

我忘了改变我的身份：

    $strSQL .=" order  by id DESC LIMIT $Page_Start , $Per_Page";
$objQuery  = mysql_query($strSQL) or trigger_error(mysql_error());;

应该是：

    $strSQL .=" order  by addedrec_ID DESC LIMIT $Page_Start , $Per_Page";

请允许我再次表示感谢，祝大家度过美好的一天。

Answer 1

您的查询以某种方式失败，并返回一个布尔值FALSE而不是语句句柄。添加此内容以找出原因：

$query = mysql_query(...);
if ($query === FALSE) {
   die(mysql_error());
}

永远不要假设数据库操作成功。

Answer 2

您的查询可能有错误。尝试做

$query = mysql_query("SELECT * FROM Register WHERE Email= '$haha'") or trigger_error(mysql_error());

查看错误是什么。

Answer 3

您的查询可能失败并返回FALSE。添加以下内容：

$query = mysql_query("SELECT * FROM Register WHERE Email= '$haha'");

if (!$query)
    die(mysql_error());

while ($row = mysql_fetch_array($query)){

Answer 4

您不得返回该查询的任何结果。在使用mysql_fetch_array（）之前检查$ query是否是资源。

 if (! is_resource($query)) { die "Database returned nothing;" }

mysql_fetch_array（）期望参数1是资源错误
