php - 平均查询的总轮数

Question

任何人都可以帮我解决我的查询...在我当前的查询中，我计算特定人的总分的平均值，结果类似于 4.232398 我希望它自动舍入最终分数，因此不是小数类型输出......任何人都可以帮助我。

我的查询:

SELECT DISTINCT 
(SELECT SUM(t2.inttotal)
 FROM app_interview2 AS t2 
 WHERE t2.atic = t.atic)/7
 AS interview_sum,

(SELECT SUM(o2.ototal)
 FROM other_app2 AS o2 
 WHERE o2.oaic = t.atic)/7
 AS other_sum,

atid,
atic,
atname,
region,
town,
uniq_id,
position,
salary_grade,
salary
FROM app_interview2 AS t
WHERE uniq_id = '$q'
GROUP BY t.atname HAVING COUNT(DISTINCT t.atic)

Answer 1

SELECT ROUND(SUM(t2.inttotal), x) 其中 x 是您需要的小数位数。
