Answer 1

There are multiple ways of doing this. One way would be:

SELECT *
FROM
(
  SELECT
  ROW_NUMBER() OVER ( ORDER BY
  CASE WHEN @sortOrder = 'name' and @sortDir = 'asc' then name
  END ASC,
  CASE WHEN @sortOrder = 'name' and @sortDir = 'desc' THEN name
  END DESC,
  CASE WHEN i(@sortOrder = 'created_date' and @sortDir = 'asc' THEN created_date
  END ASC,
  CASE WHEN i(@sortOrder = 'created_date' and @sortDir = 'desc' THEN created_date
  END ASC) RowNum
  *
)
order by 
RowNum

You can also do it using dynamic sql.
