SubSonic 내부 조인 문제 선택

나는 3 개의 테이블을 가지고 있으며 어떤 recoreds를 선택해야합니까? 그 중 2 개의 테이블에서 동일한 이름의 fileds를 가지고 있는데 Where Where Expression을 사용하려고하면 오류 메시지가 나타납니다 : If 나는 TABLENAMe.Columns.COLNAME이 오류 메시지를 보여줍니다 : 모호한 열 이름 'FKLoginID'를 사용합니다. TableNAme.COLColumn.QualifiedName을 사용하는 경우 "@ [dbo]. [Tbl_PersonalInformation]. [FKLoginID] 0"근처에 오류가 있습니다.SubSonic 내부 조인 문제 선택

어떻게 이러한 테이블을 쿼리 할 수 있습니까? 감사

당신은 내가 게시 된 쿼리를 시도이 오류 메시지가 있어요? –

아담, 당신의 쿼리를 확인, 은 SQLQuery 쿼리 = DB.Select(). (Tables.TblStockbrokerBroadDirector) .InnerJoin (Tables.TblPersonalInformation) .InnerJoin (Tables.TblCompanyInformation) 어디에요 (TblPersonalInformation.FKLoginIDColumn)에서 .IsEqualTo (User.Identity.Name); 하지만 여전히 개체 참조가 개체의 인스턴스로 설정되어 있지 않습니다. – Ashian

TblPersonalInformation.FKLoginIDColumn을 사용하지 말고 TblPersonalInformation.Columns.FKLoginID를 사용하십시오. –

다음은 작동합니다 :

SqlQuery query = DB.Select().From(Tables.TblStockbrokerBroadDirector) 
    .InnerJoin(TblPersonalInformation) 
    .InnerJoin(TblCompanyInformation) 
    .Where(TblPersonalInformation.Columns.FKLoginIDColumn).IsEqualTo(User.Identity.Name);

변경

.Where(TblPersonalInformation.FKLoginIDColumn.QualifiedName).IsEqualTo(User.Identity.Name);

당신이 전화

.Where(TblPersonalInformation.FKLoginIDColumn).IsEqualTo(User.Identity.Name);

로는 .QualifiedName 당신은 실수로 어디 (문자열 협력을 요구하고있다 lumnName) 대신 Where (TableColumn 열).

q.BuildSqlStatement()의 값을 확인하여이를 확인할 수 있습니다. 이것은 디버깅에 매우 유용합니다.
