Самы нормальный способ динамической сортировки для T-SQL

DECLARE @SortType TINYINT, @SortAscending BIT, @FirstRow INT, @MaxRows INT;
SELECT @SortType = 2, @SortAscending = 0, @FirstRow = 10, @MaxRows = 10;

WITH FoundCustomers AS
(
    SELECT
        ROW_NUMBER() OVER
        (
            ORDER BY 
                CASE WHEN @SortType = 0 AND @SortAscending = 1 THEN c.ContactName END ASC
                ,CASE WHEN @SortType = 0 AND @SortAscending = 0 THEN c.ContactName END DESC
                ,CASE WHEN @SortType = 1 AND @SortAscending = 1 THEN c.CompanyName END ASC
                ,CASE WHEN @SortType = 1 AND @SortAscending = 0 THEN c.CompanyName END DESC
                ,CASE WHEN @SortType = 2 AND @SortAscending = 1 THEN c.Country END ASC
                ,CASE WHEN @SortType = 2 AND @SortAscending = 0 THEN c.Country END DESC
        ) AS RowNumber
        ,c.*
    FROM
        dbo.Customers c
)
SELECT
    fc.*
FROM
    FoundCustomers fc
WHERE
    fc.RowNumber BETWEEN @FirstRow AND @FirstRow + @MaxRows - 1
ORDER BY
    fc.RowNumber;

Я до этого всё перепробовал.
