我需要总结一下我从现有查询中得到的结果。它必须扩展当前查询并保持单个查询
(我的意思是NOT - DO 1; DO 2; DO3;)
我目前的查询是:
SELECT SUM((count)/(SELECT COUNT(*) FROM mobile_site_statistics WHERE campaign_id='1201' AND start_time BETWEEN CURDATE()-1 AND CURDATE())*100) AS percentage FROM mobile_site_statistics WHERE device NOT LIKE '%Pingdom%' AND campaign_id='1201' AND start_time BETWEEN (CURDATE()-1) AND CURDATE() GROUP BY device ORDER BY 1 DESC LIMIT 10;
返回:
+------------+
| percentage |
+------------+
| 47.3813 |
| 19.7940 |
| 5.6672 |
| 5.0801 |
| 3.9603 |
| 3.8500 |
| 3.1294 |
| 2.9924 |
| 2.9398 |
| 2.7136 |
+------------+
我需要的是该表的总数(前10个设备使用的总百分比)(全部是)但它必须是单个查询(必须包含初始查询)(必须是单个查询到期)到另一个使用查询的程序)
这可能吗?到目前为止我尝试过的每一种方式都失败了。我们尝试了临时表,但这变成了多个查询。
答案 0 :(得分:1)
做一个
SELECT SUM(percentage) AS total FROM (<YOUR_QUERY>) a
并将子查询<YOUR_QUERY>
替换为您的初始查询
