smo gendan database

Jeg har brugt SMO for at gendanne databasen. Jeg deler min kode. Håber det hjælper. Denne løsning har dog en advarsel, den mener, at du kun har én primær datafil. At komme til at matche log- og datafilerne er virkelig svært, og noget kan gå galt på mange måder. Prøv i hvert fald og lad mig vide det, det hjælper.
