Oracle SQL問合せヘルプ - 学生の出席

Question

私は、スポーツや学校での活動に参加した学生の毎日の出席（期間1〜10）を取得する以下の問合せを持っています。私はその期間のうちの少なくとも1つの欠席の学生を見たいと思うので、すべての期間の出席コードがNULLの場合、出席してはいけません。私はどのようにクエリにそれを追加するか分からない。誰も助けることができますか？

SELECT DISTINCT

ここにデータのサンプルを示します。私はすべてのピリオドがNULLのときに行を見たくない。彼らに欠席コードがある場合のみ。私はあなたが扱っているデータについては非常に非常に少しを知っている一方で、私は出発点としてこれを提案したいData Sample

Answer 1

明らかに私はあなたが思ったことを理解していません。ビットのようになります。新しいクエリを作る私はを提供しているものを取る：

SELECT 
     s.*, att.* -- choose which columns you want, form these sources or other you can add to it 
from students AS s 
INNER JOIN (
      SELECT 
        studentid 
        , max(case when period_number='1' then attcodes end) per1 
        , max(case when period_number='2' then attcodes end) per2 
        , max(case when period_number='3' then attcodes end) per3 
        , max(case when period_number='4' then attcodes end) per4 
        , max(case when period_number='5' then attcodes end) per5 
        , max(case when period_number='6' then attcodes end) per6 
        , max(case when period_number='7' then attcodes end) per7 
        , max(case when period_number='8' then attcodes end) per8 
        , max(case when period_number='9' then attcodes end) per9 
        , max(case when period_number='10' then attcodes end) per10 
      FROM (
        SELECT 
          attm.studentid 
         , attm.period_number 
         , listagg(attm.att_code,'|') within group (order by attm.att_code) attcodes 
        FROM pssis_attendance_meeting attm 
        WHERE attm.att_date=to_date('14-Dec-2017') 
        AND attm.att_code IS NOT NULL 
        GROUP BY 
          attm.studentid 
         , attm.period_number 
       ) d 
      GROUP BY 
        studentid 
    ) AS att on s.studentid = att.studentid 

あなたは、あなたがしたい列を選択し、あなたが好きな場所を形成していますが、私はあなたを与えているサブクエリを使用している場合、 INNER JOINを使用して、 "not null"問題を解決します。

ご理解ください。

Answer 2

：

SELECT 
     studentid 
     , max(case when period_number='1' then attcodes end) per1 
     , max(case when period_number='2' then attcodes end) per2 
     , max(case when period_number='3' then attcodes end) per3 
     , max(case when period_number='4' then attcodes end) per4 
     , max(case when period_number='5' then attcodes end) per5 
     , max(case when period_number='6' then attcodes end) per6 
     , max(case when period_number='7' then attcodes end) per7 
     , max(case when period_number='8' then attcodes end) per8 
     , max(case when period_number='9' then attcodes end) per9 
     , max(case when period_number='10' then attcodes end) per10 
FROM (
     SELECT 
       attm.studentid 
      , attm.period_number 
      , listagg(attm.att_code,'|') within group (order by attm.att_code) attcodes 
     FROM pssis_attendance_meeting attm 
     WHERE attm.att_date=to_date(SYSDATE) 
     AND attm.att_code IS NOT NULL 
     GROUP BY 
       attm.studentid 
      , attm.period_number 
    ) d 
GROUP BY 
     studentid 
; 

これは、出席コードの10列を持つ学生ごとに1行を生成します。私はあなたがなぜ単一の期間のために複数の出席コードを持っているのか分からないが、あなたがそうした場合に備えてlistagg（）の使用を続けた。

このクエリでは、ロジックは、その日に登録された出席コードがない生徒を削除します。

これが全体の解決策に役立つことを願っています。

Answer 3

はあなたの忍耐をありがとう！以下の質問は、アクティビティ/スポーツに参加している学生の全期間の出席を引き出すために働いています。今は、1つ以上の期間に不在があったときだけ、レコードを表示しようとしています。私はattm.att_codeをNULLにするのを追加しようとしましたが、私はすべての期間にそうする方法を見つけることができませんでしたので、明らかに動作しませんでした。複数のスポーツ/アクティビティに登録されている学生の場合、複数の行を取得できますが、出席は両方の行で同じになります。

出席者をスポーツ/アクティビティ別にグループ化したいのですが、クエリ終了時にGROUP BY co.course_nameを追加すると、どちらも機能しません。
