This works in SQL but I want  to write it in LINQ. Is this correct in LINQ?

LINQ
   //1. check if productId, PromotionId and Serial number exist 
            var p = (from s in _dataContext.Consumers
                where s.ProductId == model.ProductId &&
                      s.PromotionId == model.PromotionsId &&
                      s.ProductSerialNumber == model.SerialNumber
                select s);

            if (p != null) //row exists
                return false;

Open in new window


In SQL
if exists (select * from consumer where [ProductId] = @productId
                                         And [ProductSerialNumber] = @SerialNumber
										 and [PromotionId] = @PromotionId)
   return false

I believe your LINQ is correct, however, I don't think your if will work. You need to actually execute the query. Try:

if (p.Any())
