SQL Server 2012에 데이터베이스 뷰를 추가했습니다.이 EntityFramework (v6) 모델을 업데이트 한 후 빌드하고 유효성을 검사했습니다. ASP.Net WebAPI (v2) 프로젝트에서이 최신 업데이트를 참조하고 있는지 확인하기 위해 참조를 제거하고 EntityFramework 라이브러리를 추가했습니다. 콘트롤러에는 컨텍스트와 EF 모델 클래스에 대한 모든 올바른 링크가 있습니다. . 다음과 같은 오류가의 InnerException에 반환되는 런타임시WebAPI 컨트롤러가 실행될 때 EntityFramework 6 모델이 반영되지 않음
public IEnumerable<RTV_DedicationComments> Get(int EntryNum)
{
//var query = from c in context.RTV_GetAllDedicationsNames orderby c.DedicationName where c.DedicationName.StartsWith(Name) select c;
var query = context.RTV_DedicationComments
.Where(d => d.EntryNumber == EntryNum)
.OrderBy(d => d.EntryNumber)
.Select(d => d);
var results = query.ToList();
return results;
}
: { "잘못된 열 이름 'PlatEntryNumber는'\ 연구 \ nCould 뷰 또는 함수를 사용하지 난이 GET 방식에서 만든 업데이트를 참조에 오류가 없습니다 때문에 바인딩 오류 'dbo.RTV_DedicationComments' "} 쿼리가 실행됩니다.
가'PlatEntryNumber'는 데이터베이스와 업데이트에 앞서 EF 모델 출신
var results = query.ToList();
이가 제거 된 UT하고 표시되지 않습니다 컨트롤러의 dbcontext 필드입니다.
나는 쿼리가 실행 된 경우 확인하기 위해 SQL 서버 프로파일 켜져 있고 그것은했다 :
exec sp_executesql N'SELECT
[Project1].[EntryNumber] AS [EntryNumber],
[Project1].[CommentDate] AS [CommentDate],
[Project1].[Comment] AS [Comment],
[Project1].[CommentBy] AS [CommentBy]
FROM (SELECT
[Extent1].[EntryNumber] AS [EntryNumber],
[Extent1].[CommentDate] AS [CommentDate],
[Extent1].[Comment] AS [Comment],
[Extent1].[CommentBy] AS [CommentBy]
FROM (SELECT
[RTV_DedicationComments].[EntryNumber] AS [EntryNumber],
[RTV_DedicationComments].[CommentDate] AS [CommentDate],
[RTV_DedicationComments].[Comment] AS [Comment],
[RTV_DedicationComments].[CommentBy] AS [CommentBy]
FROM [dbo].[RTV_DedicationComments] AS [RTV_DedicationComments]) AS [Extent1]
WHERE ([Extent1].[EntryNumber] = @p__linq__0) AND (@p__linq__0 IS NOT NULL)
) AS [Project1]
ORDER BY [Project1].[EntryNumber] ASC',N'@p__linq__0 int',@p__linq__0=5943651
나는 WebAPI와 EF 사이의 이러한 데이터베이스 객체 참조의 잔재를 제거 확인할 수 있습니다 다른 무엇
