MySQLi查詢不斷返回錯誤

Question

誰能幫我弄清楚為什么我總是出錯？

謝謝！

錯誤運行查詢時出錯[[where子句中的未知列'test']]

碼

$pagina = 'test';

$sql_pag = <<<SQL
    SELECT * 
    FROM `paginas` 
    WHERE `naam` = $pagina
SQL;

    if(!$result_pag = $db->query($sql_pag)){
        die('There was an error running the query [' . $db->error . ']');
    }

    while($row_pag = $result_pag->fetch_assoc()){
        echo $row_pag['inhoud'];
    }

桌子布置

CREATE TABLE IF NOT EXISTS `paginas` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `naam` text NOT NULL,
  `inhoud` text NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ; 

表內容

id | naam | inhoud 
1 | test | contents

如果變量是字符串，而naam列是文本，則需要用引號引起來，因此請這樣做。

WHERE `naam` = '$pagina'
