Question

I have the following query:

select distinct(ab.id) 
from WidgetClicks ab
join  ManufacturerWidgets aa 
    on ab.ManufacturerWidgetId = aa.Id
join ManufacturerRetailers ad 
    on aa.ManufacturerId = ad.ManufacturerId
join Products ac 
    on ab.ProductId = ac.Id  
where ad.Enabled = 0 
    and ad.RetailerId = 189 
    and  aa.ManufacturerId = 46  
    and aa.CountryId = 72 
    and ac.Id = 6914 
    and ab.CreatedAt >= '2011-10-31 00:00:00.000' 
    and ab.CreatedAt <= '2012-03-31 00:00:00.000'   

With enabled = 1 and the retailerId I get exactly the same results even though I shouldn’t – the results should be a lot fewer.

I’m sure its something straightforward but its driving me mad! any help appreciated

EDIT:

What i actually need to do is basically write 3 statments to get the results – again not certain how to do this but this is what the statment needs to do (in plain english):

1. From the affiliateretailer table select * where manufacturerid = 46 and enabled = true

2. Select * from manufacturerRetailer where the retailers are the ones remaining in the above selection where manufacturerid = 46

3. Select * from widgetClicks join on retialer d where productid = abc and wc.CreatedAt >= ‘2011-10-31 00:00:00.000’ and wc.CreatedAt <= ‘2012-03-31 00:00:00.000’

Edit **

Right i’ve got the Sql query that i want…

    SELECT COUNT(*) 
    FROM WidgetClicks 
    WHERE CreatedAt >= '2011-10-31 00:00:00.000' 
    and CreatedAt <= '2012-03-31 00:00:00.000' 
    and ProductId = 6914 
    AND RetailerId in (
                        SELECT RetailerId 
                        FROM AffiliateUpdateFiles auf
                        WHERE auf.Enabled = 1 AND auf.ManufacturerId = 46 and RetailerId <> 189
                        )
    AND ManufacturerWidgetId in (
                                select id 
                                from ManufacturerWidgets 
                                where  ManufacturerId = 46 and CountryId = 72
                                )

Here’s the thing thoug – I actually need it in Linq – if anyone can convert it for me it woudl be appreciated… i will be having a go!

Answer 1

Here is the solution for converting the above to Linq:

public int GetWidgetClicksForManufacturerCategoryModel(int manufacturerId, int countryId, int categoryId, int productId, DateTime myStartDate, DateTime myEndDate)
        {
            var widgetInCountry = (from mw in _er.ManufacturerWidgets
                                                where mw.ManufacturerId == manufacturerId && mw.CountryId == countryId
                                                select mw.Id).ToList();

            var enabledWidgets = (from auf in _er.AffiliateUpdateFiles
                        where auf.Enabled && auf.ManufacturerId == manufacturerId 
                        select auf.RetailerId).ToList();



            var widgetClicks = (from wc in _er.WidgetClicks
                          where wc.CreatedAt.CompareTo(myStartDate) >= 0 && wc.CreatedAt.CompareTo(myEndDate) <= 0 
                          && wc.ProductId == productId 
                          && enabledWidgets.Contains(wc.RetailerId) 
                          && widgetInCountry.Contains(wc.ManufacturerWidgetId)
                                               select wc.Id);

            return widgetClicks.Count();
        }
