I tried all combinations - GROUP BY - ORDER BY - GROUP BY & ORDER BY the result is always the same. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

Sort orders are > notorious for being surprising across collations. What's this one? Thank you very much for your reply. Yes, I tried ORDER BY, and the result is the same. I am not sure about collations; I guess I will have to read up on this subject. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
[GENERAL] Result of ORDER-BY
[PostgreSQL 8.3.9] I have a query, as follows SELECT DISTINCT ON(category) category FROM gdb_books WHERE category LIKE 'Fiction%' GROUP BY category The (partial) result is this: ... # Fiction - General (A) # Fiction - General - Anthologies # Fiction - General (B) # Fiction - General (C) # Fiction - General (D) ... I would have expected '- Anthologies' to be either at the top, or at the bottom of the result. Does anyone have an explanation why this is not so; are the special characters (parenthesis, hyphen) just ignored? If so, is there a way to force ORDER BY to include the special characters in the sort? Thank you for any reply.
