SQL按照年月员工状态统计出勤情况

Posted 2022-05-21 ShenLiang2025

需求描述

表名:employeesign

列名:emp_date和emp_status

求一月份有多少人请假，多少人签到等

最终得到如下结果：

解决方法

 通过SQL里的聚合函数结合CASE WHEN来完成统计。

SQL代码

-- 1 创建表(以mysql版为例)
CREATE TABLE emp_temp 
(
id varchar(30),
create_by varchar(10),
create_time datetime,
update_by	varchar(10),
update_time	datetime,
sys_org_code varchar(10),
emp_name varchar(20),
emp_date	datetime,
emp_status SMALLINT,
emp_pic	 varchar(30),
remark  varchar(20)
)

-- 2 按照年月份、考勤状态统计
SELECT 
DATE_FORMAT(emp_date,'%Y-%m') '年月份',
COUNT(CASE WHEN emp_status = 0 THEN 1 ELSE NULL END) '正常签到',
COUNT(CASE WHEN emp_status = 1 THEN 1 ELSE NULL END) '未签到',
COUNT(CASE WHEN emp_status = 2 THEN 1 ELSE NULL END) '缺勤',
COUNT(CASE WHEN emp_status = 3 THEN 1 ELSE NULL END) '请假'
FROM
(
SELECT max(emp_date) emp_date,id,emp_status FROM emp_temp
GROUP BY id
)A
GROUP BY  DATE_FORMAT(emp_date,'%Y-%m')

-- 3 结果
/*
年月份    正常签到    未签到    缺勤    请假
2020-09	  1    0    0    0
2020-12	  0    1    1    2
2021-01	  6    3    12    10
*/
