테이블 데이타도 같고 쿼리문도 같은데 쿼리결과값이 다르게 나올 수 있나요?
레코드가 20개 정도가 인터베이스 쪽이 더 나오네요
참고로 쿼리문은 다음입니다.

select (a.fRes1_code) A, (a.fR_jung) B,(b.stud_name) C,         (b.stud_sex) D, (a.fR_jochi) E,        
    (a.sokyun) F,(a.fR_doctor) G, (c.sec2_sokyun) H            
from Fir1Result2002 a
    Left outer join student b                                        
      on a.fRes1_jumin=b.stud_jumin  

left outer join Fir2Result2002 c on                                    
    a.fRes1_code=c.sec2_code and c.sec2_code=(                                
      select (d.sec2_code) from Fir2Result2002 d                        
      where c.sec2_jumin=d.sec2_jumin  and d.sec2_code like "011%"
         and  (d.sec2_gubun="C" or d.sec2_gubun="D2") )            
where  a.fR_jung="R" and a.fRes1_code like "011%"

제발 답변 좀 해주세요!
