Fehler in unserem SQL oder Entity Framework?

Question

Ich habe etwas SQL von unserem DBA, das ich nur überprüfe, es ist richtig, da die EF Entitäten nicht vollständig zu verknüpfen scheint. Es weiß, dass es eine Beziehung gibt, führt aber den FK-zu-PK-Link nicht durch.

Alle Ideen oder Gedanken (anstatt NHibernate verwenden!) Darauf geschätzt.

Answer 1

Sie haben festgelegt NOCHECK auf Fremdschlüssel-Constraints

ALTER TABLE [dbo].[Employee] NOCHECK CONSTRAINT [FK_Employee_People] 

Plus, haben Sie einen doppelten Index für Mitarbeiter.
