如何从mysql的结果中删除十进制数字？

Question

I want to remove digit after decimal how to solve it?

My query is:

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;           

Output

+-------------------------+-------------------------+-------+------------+----------+------------+--------------+-----------+---------+
|       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 |

| Ahmedabad | mahesh.patel@corp.in | 297 |100.0000% | 0.0000% | 147.0667 | 154292.9333 | 43.4343% | 4.4031 |

Answer 1

1. If you want to round off decimal places, use ROUND(yourColumn,0) function.

   So 13.78 will become 14

2. If you want to get rid of decimal places, user FLOOR(yourColumn)

   So 13.78 will become 13

So for example

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

should be changed to

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

Edit: This would take care of your % .

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

Do the same for all the columns you need to remove decimal places.

Answer 2

例如，您应该在 Mysql 中使用 TRUNCATE()

SELECT TRUNCATE(525.668545, 3) -- 525.668
