如何從mysql結果中刪除十進制數字？

Question

我想在十進制後刪除數字如何解決它？

我的查詢是：

SELECT city_name, 
     Assignedto, 
     COUNT(Assignedto) AS TC, 
     CONCAT(count(CASE 
         WHEN STATUS = 'CLOSED' THEN 1 
         ELSE NULL 
        END) * 100/count(1), '%') AS SC, 
     CONCAT(count(CASE 
         WHEN STATUS = 'PENDING' THEN 1 
         ELSE NULL 
        END) * 100/count(1), '%') AS PC, 
     SUM(TIMESTAMPDIFF(MINUTE,Request_Date, Xetr))/60 AS WH, 
     (154440-sum(TIMESTAMPDIFF(MINUTE,Request_Date, Xetr))/60) AS VH, 
     CONCAT(COUNT(Feedback_Rate)/COUNT(Assignedto)*100,'%') AS Feed_Percent, 
     SUM(Feedback_Rate)/(count(Feedback_Rate)*5)*5 AS AVG_Feedback 
FROM `it_service_ticket` 
INNER JOIN `it_problem`ON `it_service_ticket`.`it_problem_id`=`it_problem`.`it_problem_id` 
INNER JOIN `city_master` ON `it_service_ticket`.cityid=`city_master`.city_id 
WHERE `it_service_ticket`.`xetr` BETWEEN '2016-04-01 12:00:00 AM' AND '2017-02-28 12:00:00 PM' 
GROUP BY Assignedto 
ORDER BY city_name ASC;   

輸出

+-------------------------+-------------------------+-------+------------+----------+------------+--------------+-----------+---------+ 
|  City_Name   |  AssigneeTo  | TC | SC  | PC  | WH  |  VH  | Feedback | Average | 
+-------------------------+-------------------------+-------+------------+----------+------------+--------------+-----------+---------+ 
| Ahmedabad    | mahesh.patel@corp.in | 297 | 100.0000% | 0.0000% | 147.0667 | 154292.9333 | 43.4343% | 4.4031 | 

|艾哈邁達巴德| mahesh.patel@corp.in | 297 | 100.0000％| 0.0000％| | 147.0667 | 154292.9333 | 43.4343％| 4.4031 |

Answer 1

1. 如果要舍入小數位數，請使用ROUND(yourColumn,0)函數。

   所以13.78將成爲14

2. 如果你想擺脫的小數位，用戶FLOOR(yourColumn)

   所以13.78將成爲13

因此，例如

SUM(TIMESTAMPDIFF(MINUTE,Request_Date, Xetr))/60 AS WH

應改爲

ROUND(SUM(TIMESTAMPDIFF(MINUTE,Request_Date, Xetr))/60,0) AS WH

編輯：這將需要你的%照顧。

CONCAT(
     ROUND(count(CASE 
      WHEN STATUS = 'PENDING' THEN 1 
      ELSE NULL 
     END) * 100/count(1),0) 
     , '%') AS PC 

對所有需要刪除小數位的列執行相同的操作。
