私はこれに基づいてレポートを生成しますが、

を記録し、これは

select * from 
( 
select student_name, student_status,attendance_code, 
working_date,class_id from 
( 
select to_char(a.date_tm,'yyyy-mm-dd hh24:mi:ss') AS working_date,

where a.school  = 'DON BOSCO'

and a.date_tm >= to_date('2017-11-10 06:00:00','yyyy-mm-dd hh24:mi:ss') 
and a.date_tm <= to_date('2017-11-11 18:00:00','yyyy-mm-dd hh24:mi:ss')

PIVOT 
( 
max(attendance_code) as code, 
max(student_status) as status 
for student_name in ('JAMES','PETER','MURPHY','MICA','STELLA','STEPHEN','TRACY'); 
) ;

結果のように私のクエリです：以上の結果から

、あなたが見ることができますデータが正しくありません。

Jamesは、彼のコード2344から見ることができる2つのセッションに欠席していますが、ステータスはまだPresentとして表示されています。同じ問題はレコード全体で発生します。

私は間違っていますか？

ご意見は&と非常に高く評価されていますか？

分（student_status）はMAX（attendance_code）

不在== 2344
本== 1001

に相当するので、それに応じて

select * 
from ( 
    select 
      student_name, student_status,attendance_code,working_date,class_id
