使用PHP从数据库获取行错误

我试图从数据库中的表中获取一行，除了一列(page_content)之外，所有内容都成功检索了，其数据部分进入。下面是表创建代码:

CREATE TABLE 'usol_site_page' (

有人知道为什么page_content没有被完全检索吗?

下面是查询代码:

$extendQry = "";
            if($mode != "admin"){
                $extendQry = "AND p.status='enable' ";
            }
             $qry = "SELECT p.page_id, p.page_link, p.page_name, p.page_heading, p.page_content, p.status, p.page_title,
                            p.meta_keywords, p.keyword_description, p.pic_main, p.pic_small, p.parent_page_id, 
                            t.page_type_id, t.page_type, m.page_menu_id, m.menu_type
                       FROM usol_site_page p, usol_page_type t , usol_page_menu m
                      WHERE p.page_id = ".$pageId." $extendQry
                        AND t.page_type_id = p.page_type_id 
                        AND m.page_menu_id = p.page_menu_id";
$result = mysql_query($qry);
return mysql_fetch_row($result);
