단일 테이블을 쿼리하기 위해 springframework HibernateTemplate을 사용하고 있습니다. 디버그 설정을 사용하여 Hibernate가 생성하는 쿼리를 캡처하여 Toad에서 실행하고 75 개의 별개의 행을 확보했습니다. 그러나 내 응용 프로그램에서는 75 개의 중복 레코드가있는 컬렉션을 얻습니다.springframework/hibernate가 중복 행을 반환합니다.

을 그리고 이것은 쿼리가 두꺼비에서 제대로 작동 생성 :
select this_.member_id as member1_45_0_,
this_.week_ending as week2_45_0_,
this_.actual_invoice as actual3_45_0_,
this_.ftr_adjustments as ftr4_45_0_,
this_.edc_lse_adjustments as edc5_45_0_,
this_.blid_adjustments as blid6_45_0_,
this_.pma_misc_adjustments as pma7_45_0_,
this_.pma_early_payments as pma8_45_0_,
this_.adj_inv as adj9_45_0_,
this_.adj_inv_exc_early_payment as adj10_45_0_,
this_.initial_pma as initial11_45_0_,
this_.three_week_pma as three12_45_0_,
this_.pma_override as pma13_45_0_,
this_.pma_override_type as pma14_45_0_,
this_.pma_override_reason as pma15_45_0_
from ecredit.v_pma_summary this_
where this_.member_id = 10003
order by this_.week_ending desc;
이 테이블에는 복합 키가 있습니다. 복합 키의 단일 속성에서 두 속성으로 변경하면 문제가 해결되었습니다. –
