I have a simple query from a view in SQL Server:
SELECT [PricePerM]
FROM RealtyStatParent
ORDER BY PricePerM
When I execute a query in SQL Management Studio, I get the correct results. This means that I get 2532 lines, starting from 1.00 and ending with 173543.6893.
When I make a request from C # using the framework entity, I got the same results:
var justDecimals = context.RealtyStatParents
.OrderBy(item => item.PricePerM)
.Select(item => item.PricePerM)
.ToArray();
Nothing special so far. But what I really don't understand is the following query. First I select the whole lines, and then I select the price (decimal).
var entireRows = context.RealtyStatParents
.OrderBy(item => item.PricePerM)
.ToArray();
var decimalFromRows = entireRows
.Select(item => item.PricePerM)
.ToArray();
Many PricePerM values are repeated (value 1 or 48) instead of the actual value, and the result set is not properly ordered.
Defining a string in an EF designer is simple:
public partial class RealtyStatParent
{
public Nullable<decimal> PricePerM { get; set; }
public int BusinessCategory { get; set; }
public decimal obec_kod { get; set; }
public Nullable<int> ParentCategoryId { get; set; }
}
