Question

I have a problem with my SQL statement:
I use SELECT statement and then CASE when I use order by.

SELECT .....
ORDER BY
CASE WHEN @sort = 'ND' THEN name END DESC,
CASE WHEN @sort = 'NA' THEN name END,
CASE WHEN @sort = 'AD' THEN (isAuthorized)  END DESC,
CASE WHEN @sor = 'AA' THEN (isAuthorized) END

isAuthorized is a BIT value, so I would like to use secondary order by there.

I tried something like:

SELECT .....
ORDER BY
CASE WHEN @sort = 'ND' THEN name END DESC,
CASE WHEN @sort = 'NA' THEN name END,
CASE WHEN @sort = 'AD' THEN (isAuthorized, name )  END DESC,
CASE WHEN @sort = 'AA' THEN (isAuthorized, name ) END       

But it doesn’t work.

I use SQL server 2008.

Any help would be greatly appreciated.

Answer 1

If you want order the result set first by name and then by isAuthorized when @sort = ND use this query:

SELECT .....
ORDER BY
CASE WHEN @sort = 'ND' THEN name END DESC,
CASE WHEN @sort = 'ND' THEN isAuthorized END

You can combine CASE clauses. I hope you got the idea.
