linq 및 저장 프로 시저

Question

LINQ에서 저장 프로 시저를 실행하려고합니다. SQL Server에서 실행하면 정수 필드와 부동 소수점 필드와 같은 여러 필드가 반환됩니다. 저장된 PROC 여기

var meterReadings = _database.MetricDataReport("20101127"); 

그리고있다 :

나는 '돈을 내가 LINQ에 저장 프로 시저를 호출 할 때, 그것은 반환 모든 내가 저장 프로 시저를 호출 오전 방법은 다음과 0이다 문제가 무엇인지 알기에는 이것에 대해 충분히 알고 있지만 훨씬 간단한 저장 프로 시저를 사용하여이 작업을 먼저 수행하고 싶을 수도 있습니다. 예 : 단순한 목록을 반환하는 것.

또한 Linq to Sql과 함께 Stored Procs를 사용하는 경우 ScottGu's blog post을 살펴보십시오.
