예. 위와 같은 테이블이 있는데 다음과 같은 데이터를 얻고 싶습니다. 감사. :)

IncidentReportid    Interviewers  MainInterviewer    
18        Name    nric 
19        irank   inric     
20        irank5   inric5    
21        irank7   inric7     
23        irank9   inric9     
24        RankOfAddison aNRIC 

가장 중요한 것은 'Interviewers'이름을 주 인터뷰 'NRIC에 따라 달라집니다.
