QueryOver Select가 Count보다 많은 결과를 가져옵니다.

Question

검색 기준에 따라 맞지만 결과가 반환되지만 QueryOver를 사용하여 검색을 시도하고 있습니다. 여기

내가 스킵와 select 문에 마지막 줄을 변경 한 다음 이렇게

return returned.OrderBy(x => x.CreatedUTC).Desc.Skip(skip).Take(take).List<Note>(); 

처럼 가지고가는 경우에 제대로

// disjunction to find query string in note text of tag list 
var disjunction = new Disjunction(); 
disjunction.Add(Restrictions.On<Note>(e => e.Text).IsInsensitiveLike(query)); 

var tagSubQuery = QueryOver.Of<Note>().JoinQueryOver(x => x.Tags).Where(x => x.Text.IsInsensitiveLike(query)).Select(x => x.Id); 
disjunction.Add(Subqueries.WhereProperty<Note>(x => x.Id).In(tagSubQuery)); 

// find notes between dates and based on disjunction 
var notes = this.DataOver.Where(x => x.CreatedUTC >= startDate && x.CreatedUTC <= endDate).Where(disjunction); 

// only show notes within permitted accounts 
var subnotes = QueryOver.Of<Note>().JoinQueryOver(x => x.Accounts).Where(x => x.Company.Id == user.Company.Id).Select(x => x.Id); 
var returned = notes.WithSubquery.WhereProperty(x => x.Id).In(subnotes); 

return returned.RowCount(); 

작동 나는 결과를 계산하기 위해 사용하고있는 코드입니다 나는 2 대신에 3 노트를 되 찾는다. 다른 하나는 괜찮지 만, 1 노트는 복제된다. 쿼리가 하나의 노트에 연결된 두 개의 태그와 일치했기 때문에 나는 그럴 수 있다고 가정 할 수 있습니다. 나는 그것이 같은 두 그중 3 개 결과를 반환하는 SQL 관리 스튜디오로 직접 넣을 경우

Answer 1

카티 션 곱을 발생시키는 왼쪽 결합 때문입니다. 이 작업을 추가하여 DistinctRootTransformer을 적용해야합니다

.TransformUsing (Transformers.DistinctRootEntity)
