Answer 1

可以通过员工代码分组统计请假人数

Select PER_CODE As [EMP CODE] , COUNT(EXC_DATE) as LEAVES from 
R5EXCEPTIONS inner join R5PERSONNEL  on PER_CODE = EXC_PERSON
group by PER_CODE

Answer 2

您可以使用聚合 SQL 查询按日期获取 PER_CODE 事件的数量。

以下表示：

select count(PER_CODE) as [EMP VOL], EXC_DATE as LEAVES
from R5EXCEPTIONS
inner join R5PERSONNEL on PER_CODE = EXC_PERSON
Group by EXC_DATE

How do I get count of leaves with respect to employee code in SQL?
