按出勤率分组 sheet

Question

我有一个 table 记录每天的出勤率。

CREATE TABLE  "DAILY_ATTENDANCE" (
    "SERIAL_NO" NUMBER(10,0), 
    "EMPLOYEE_ID" NUMBER(4,0), 
    "FIRST_NAME" VARCHAR2(100), 
    "MIDDLE_NAME" VARCHAR2(100), 
    "LAST_NAME" VARCHAR2(100), 
    "ATTENDANCE_DATE" DATE, 
    "STATUS" VARCHAR2(100) DEFAULT 'PRESENT', 
    "MONTH" VARCHAR2(100), 
    "YEAR" VARCHAR2(100), 
    CONSTRAINT "DAILY_ATTENDANCE_PK" PRIMARY KEY ("SERIAL_NO") ENABLE, 
    CONSTRAINT "DAILY_ATTENDANCE_UK1" UNIQUE ("EMPLOYEE_ID", "ATTENDANCE_DATE")       
    ENABLE
);

create or replace trigger "DAILY_ATTENDANCE_T5"
    BEFORE insert or update on "DAILY_ATTENDANCE"
    for each row
    begin
        :new.month:= to_char(:new.ATTENDANCE_DATE, 'month') ;
        :new.year:= to_char(:new.ATTENDANCE_DATE, 'YYYY') ;
    end;

我如何编写一个简单的 sql 语句来给出员工 ID 和状态的月度和年度分组？ status 有 present、sick leave 等值。例：求employee_id=1001在2015年的每个月请病假的次数有多少？

Answer 1

您可以尝试以下查询：

select a.year,a.month,a.employeeId,count(*)
from
(select * from DAILY_ATTENDANCE  where status ='sickleave')a
group by a.year,a.month,a.employeeId

按出勤率分组 sheet

group by month for attendance sheet
