MySQL查詢警告

可能重複：
mysql_fetch_array() expects parameter 1 to be resource, boolean given in select
Warning: mysql_fetch_* expects parameter 1 to be resource, boolean given error MySQL查詢警告

$query = mysql_query("SELECT MAX(id) from test"); 
$result = mysql_query($q); 
$data = mysql_fetch_array($result); 
$start = $data[0]; 
$end = $start -15; 
$query = mysql_query("SELECT * from test 
     WHERE id = BETWEEN '".$start."' AND '".$end."' ORDER BY id DESC");

誰能告訴我爲什麼我收到這個錯誤？

警告：mysql_fetch_array（）預計參數1是資源，鑑於布爾

通常是警告說，提供的參數不是一種資源。正確？

您的查詢中可能有錯誤。這導致`$ result`爲`false`。使用`echo mysql_error（）`輸出它。 – 2011-02-01 23:21:11

`$ q`不在您發佈的示例中 - 您的查詢都在`$ query`變量中。 – 2011-02-01 23:22:26

我認爲，問題是，你說的

"WHERE id = BETWEEN '".$start."' AND '".$end."'"

我不認爲應該有BETWEEN operator之前=。這將是一個語法錯誤，所以你不會得到結果集。

你認爲是正確的+1 – Endophage 2011-02-02 00:27:20

試試這個

$query = mysql_query("SELECT MAX(id) from test"); 
$result = mysql_query($query); 
$data = mysql_fetch_array($result); 
$start = $data[0]; 
$end = $start -15; 
$query = mysql_query("SELECT * from test 
    WHERE id BETWEEN '".$start."' AND '".$end."' ORDER BY id DESC");

$query = mysql_query("SELECT MAX(id) from test"); 
$result = mysql_query($q); //you don't have variable $q in this code, you mean $query 
$data = mysql_fetch_array($result); //script tell's that $result is false 
$start = $data[0]; //don't have eather 
$end = $start -15; 
$query = mysql_query("SELECT * from test 
    WHERE id = BETWEEN '".$start."' AND '".$end."' ORDER BY id DESC"); 
    //and you must write id BETWEEN, not id = BETWEEN

好了，所以我得到了它的工作。代碼如下...

$q = mysql_query("SELECT MAX(id) FROM test"); 
    $data = mysql_fetch_array($q); 
    $start = $data[0]; 

    //only shows 15 articles at a time 
    if($start>16) 
    { 
     $end = $start -15; 
    } 

    else 
    { 
     //Sets the minimum id to 1 
     $start = 1; 
    } 

    $query = mysql_query("SELECT * from test WHERE id BETWEEN '".$end."' AND '".$start."' ORDER BY id DESC");

對於一個$查詢需要$ q，並且我的$ start和$ end需要切換。感謝您爲所有人提供幫助！
