i'm currently maintaining a C# based back end system and i'm in need to get a list of objects from the sql server from a simple id, but the entire system is done through sqlcontext actions, unfortunately i cant seem to find a good response to what i need. Is there a good way to get this list of objects using that? All i need is to return all the entries that have this id on their eventId column.
this is a example of what the system do, this is a function that returns one entry, but i'm not sure if it will do what i want:
public async Task<EventDate> GetById(int id)
{
return await _sqlContext.EventDate
.Include(x => x.Hours)
.Include(x => x.Event)
.Where(x => x.Id == id)
.AsNoTracking()
.FirstOrDefaultAsync();
}
i would be grateful if someone could explain that to me a little more, i'm not so experienced in that regard and i cant seem to find any good explanations.
Edit: Due to a request, here is the create script for the EventDate table:
SET ANSI_NULLS ON
