ORDER BY is applied to the results of the entire query. Then LIMIT takes a slice out of the results (paginate). My guess, the problem you are experiencing is you are viewing page 2 of 5 of your output in ASC order, then switch over to DESC without adjusting the page number. What you are seeing (roughly) for page 2 of 5 in DESC order is what used to be on page 4 of 5 in ASC order, only upside-down. :-) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I've never had any problems ordering my results based on more than one field, where the orders are based on a mixture of ASC and DESC fields. The ordering part looks something like this: ORDER BY `field1` DESC, `field2` ASC, `field3` DESC and that works just fine for me.

Here's the query: SELECT * FROM book ORDER BY $sort $dir LIMIT $offset, $records_per_page; $sort == 'title, sub_title'; $dir==ASC (or DESC); $offset== (any multiple of 10); $records_per_page== 10; I could let the user change these, but I decided it is simpler to keep it at 10 books/page. Only the $dir is user settable. The character set is utf8-general; (I just went through some self-torture changing all those foreign curlicues to :cutesy_stuff; fortunately, the mysql replace() function helped - but six languages have quite a few weird accents. The title field can be fairly long - 182 chars; sub_title is 128, but it looks like I have to lengthen that too; found some truncated inputs. -- Hervé Kempf: Pour sauver la planète, sortez du capitalisme. - Phil Jourdan --- p...@ptahhotep.com http://www.ptahhotep.com http://www.chiccantine.com/andypantry.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
