Question

I got a SQL Server table with columns ResolvedDate and ResolvedBy.

Now I want to select those two columns and count their results, which I thought I’d implement like that:

_dataContext.Activities
    .Where(a => a.IsResolved && a.ResolvedBy == userId)
    .Select(a => new { a.ResolvedDate, ***COUNT*** });

As you can see, the Count-Part is missing.

I want to get every activity, that has been done in this ResolvedDate and count it.

How can I implement that?

Answer 1

from a in dataContext.Activities
where a.IsResolved && a.ResolvedBy == userId
group a by a.ResolvedDate into g
select new {ResolvedOn=g.Key, NumberResolved= g.Count()}
