ExpressionEngine查询模块和订购SQL UNION

Question

我收到一个MySQL错误这个代码ExpressionEngine 1.6.4（很老的版本）

{exp:query limit="10" paginate="bottom" 
    sql="SELECT 'gallery' AS `content_type`, `cat_id` AS `entry_id`, `recent_entry_date` AS `entry_date` 
     FROM `exp_gallery_categories` 
     WHERE `gallery_id` = 9 AND total_files > 0 
     UNION 
     SELECT 'video' AS `content_type`, `entry_id`, `entry_date` 
     FROM `exp_weblog_titles` 
     WHERE `weblog_id` = 6 ORDER BY `entry_date` DESC" 

    } 
<p>{content_type} - {entry_id} - {entry_date format="%d %F %Y"}</p> 
{paginate}{pagination_links}{/paginate} 
{/exp:query} 

的MySQL返回此：

MySQL ERROR: Error Number: 1054 
Description: Unknown column 'entry_date' in 'order clause' 
Query: SELECT COUNT(*) AS count FROM `exp_gallery_categories` WHERE `gallery_id` = 9 AND total_files > 0 UNION SELECT COUNT(*) AS count FROM `exp_weblog_titles` WHERE `weblog_id` = 6 ORDER BY `entry_date` DESC 

似乎像EE在MySQL之前修改我的查询并使其失败（在SQL客户端上，这可以顺利运行）。

Answer 1

答案是修补mod.query.php停止对矫正查询

$query = $DB->query("SELECT COUNT(*) AS count FROM ({$sql}) AS query");

我假设您的选择查询工作。尝试下面：

sql="SELECT * FROM 
     (SELECT gallery AS content_type, cat_id AS entry_id, 
      recent_entry_date AS entry_date 
      FROM exp_gallery_categories 
      WHERE gallery_id = 9 AND total_files > 0 
      UNION 
      SELECT video AS content_type, entry_id, entry_date 
      FROM exp_weblog_titles 
      WHERE weblog_id= 6 
     ) AS TEMP 
     ORDER BY entry_date DESC" 

编辑：统计查询：

  SELECT COUNT(*) AS count 
     FROM 
      (SELECT COUNT(*) AS count, 
       recent_entry_date AS entry_date 
       FROM exp_gallery_categories 
       WHERE gallery_id = 9 AND total_files > 0 
       UNION 
       SELECT COUNT(*) AS count, 
       entry_date 
       FROM exp_weblog_titles 
       WHERE weblog_id = 6 
      ) AS TEMP 
     ORDER BY entry_date DESC
