PIVOT 기능은 내가라는 두 개의 테이블이

잘못된 출력 결과를 반환 목록을 저장할 특정 날짜PIVOT 기능은 내가라는 두 개의 테이블이

student_record_hist에 대한 클래스의 출석 항목을 저장합니다

class_record_hist 특정 클래스의 학생 출석. 여기에서 transaction_id가 두 테이블의 기본 키가됩니다.

내 데이터는 다음과 같습니다.

그리고 이것은

select * from

working_date,class_id from

PIVOT 
( 
max(attendance_code) as code, 
max(student_status) as status

) ;

결과처럼 내 쿼리입니다 : 위의 결과에서

, 당신은 볼 수 있습니다 데이터가 잘못되었습니다.

제임스의 경우 코드 2344에서 볼 수있는 두 세션 동안 결석하지만 Status는 여전히 Present로 표시됩니다. 동일한 문제는 전체 레코드에서 발생합니다.

내가 뭘 잘못하고 있니?

제안 사항 & 입력 사항을 크게 평가 하시겠습니까?

최소 (student_status)가 최대 총점 (attendance_code)

결석 == 2,344
현재 == 1,001

매우 피벗 따라서

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