Question

I’m working with SQL Server 2005.

My query is:

SELECT (
  SELECT COUNT(1) FROM Seanslar WHERE MONTH(tarihi) = 4
  GROUP BY refKlinik_id
  ORDER BY refKlinik_id
) as dorduncuay

And the error:

The ORDER BY clause is invalid in views, inline functions, derived
tables, subqueries, and common table expressions, unless TOP or FOR
XML is also specified.

How can I use ORDER BY in a sub query?

Answer 1

This is the error you get (emphasis mine):

The ORDER BY clause is invalid in
views, inline functions, derived
tables, subqueries, and common table
expressions, unless TOP or FOR XML is
also specified.

So, how can you avoid the error? By specifying TOP, would be one possibility, I guess.

SELECT (
  SELECT TOP 100 PERCENT
  COUNT(1) FROM Seanslar WHERE MONTH(tarihi) = 4
  GROUP BY refKlinik_id
  ORDER BY refKlinik_id
) as dorduncuay
