警告:mysql_fetch_array()要求参数1为resource,boolean给出

Question

可能重复:
PHP:警告:sort()期望参数1是数组,给定资源

请帮忙,

我得到以下错误:

警告:mysql_fetch_array()期望参数1是资源,在......中给出布尔值

这是我的查询:

$query = "SELECT ListNumber FROM residential"; 
$result1 = mysql_query($query); 
    if (mysql_num_rows($result1) >10){ 
        $difference = mysql_num_rows($result1) - 10; 
        $myQuery = "SELECT * FROM `residential` ORDER BY `id` LIMIT 10,". $difference; 
        $result2 = mysql_query($myQuery); 
echo $result2;
        $replace =  str_replace(", "," | ", $result2);
    while ($line = mysql_fetch_array($result2, MYSQL_BOTH))

Answer 1

您的查询($ myQuery)失败,因此不生成查询资源,而是生成FALSE.

要显示动态生成的查询的外观并显示错误,请尝试以下操作:

$result2 = mysql_query($myQuery) or die($myQuery."<br/><br/>".mysql_error());

错误消息将引导您进入解决方案,从下面的评论中,该解决方案与您正在选择的表中不存在的字段上使用ORDER BY相关.
