Question

Some LINQ queries still puzzle me.

for a table ‘Hits’ containing two columns, ‘Page’ and ‘Date’, I want to find the most Pages with the most rows in a defined slice of time.

In SQL I would use this:

SELECT TOP 10       [Page]       ,COUNT([Page]) as Number FROM dbo.[Hits] WHERE [Date] >= CONVERT(datetime,'14 Jan 2009') AND [Date] < CONVERT(datetime,'15 Jan 2009') Group BY [Page] Order by Number DESC 

In LINQ I got no idea how to approach this, can anyone help me here? I tried to convert it using linqer, but it just shows an error for this expression.

Answer 1

Something like this should work:

(from p in DataContext.Hits where (p.Date >= minDate) && (p.Date < maxDate) group p by p.Page into g select new { Page = g.Key, Number = g.Count() }).OrderByDescending(x => x.Number).Take(10);
