SQL orderby / case issue: orderdirection fail
- by Joris
I got a stored procedure that delivers a table of students, and it needs to order by surname, name etc... it also needs to sort ascending, descending, depending on the parameter @orderby...
code:
ORDER BY
CASE
WHEN @orderby = 'studentkey' THEN Studentkey END ASC,
CASE
WHEN @orderby = 'studentkey' and @desc = 1 THEN Studentkey END DESC,
CASE
WHEN @orderby = 'initials' THEN Initials END ASC,
CASE
WHEN @orderby = 'initials' and @desc = 1 THEN Initials END DESC,
CASE
WHEN @orderby = 'firstname' THEN Firstname END ASC,
CASE
WHEN @orderby = 'firstname' and @desc = 1 THEN Firstname END DESC,
CASE
WHEN @orderby = 'nickname' THEN Nickname END ASC,
CASE
WHEN @orderby = 'nickname' and @desc = 1 THEN Nickname END DESC,
CASE
WHEN @orderby = 'insertion' THEN Insertion END ASC,
CASE
WHEN @orderby = 'insertion' and @desc = 1 THEN Insertion END DESC,
CASE
WHEN @orderby = 'surname' THEN Surname END ASC,
CASE
WHEN @orderby = 'surname' and @desc = 1 THEN Surname END DESC
NED
There is a difference in output between @desc = 1 and @desc = 0, but not what i desire...
Does anyone have a solution?
