Piotrek Karaś	Wednesday 03 October 2007 11:55:26 pm Hello everyone after a bit of a break :) Can anyone give any tips as to how to deal with sorting of the fetched elements, <b>when native characters come into play</b>? Polish language, for instance, uses nine native characters (ąśżźćńłęó). How do I make eZ Publish to sort elements like this: (...) o-word ó-word [o acute] p-word (...) MySQL provides <b>utf8_polish_ci collation</b> - will that do the trick? What about multi-language installations? Is there a way to force collation based on a siteaccess for example? Of course, we're talking about UTF-8-based DB. Any help/suggestions appreciated. Thanks. -- Company: mediaSELF Sp. z o.o., http://www.mediaself.pl eZ references: http://ez.no/partners/worldwide_partners/mediaself eZ certified developer: http://ez.no/certification/verify/272585 eZ blog: http://ez.ryba.eu

But it's not possible to force collation based on site access at this moment. Maybe executing some SQL on initialization of the database can make it possible, but I didn't investigate this yet. independent eZ Publish developer and service provider \| http://blog.coomanskristof.be \| http://ezpedia.org
Piotrek Karaś	Thursday 04 October 2007 9:11:02 am Yup, you're right. Preinstallation collation setting does the trick - I've just finished several tests on utf8_general_ci against utf8_<i>native</i>_ci for the entire database. Too bad there's no native eZ Publish ability to relate collations to siteaccesses and/or language settings for MySQL db. Yes, a global setting for the moment of connecting to the database would be very useful and easy to implement - otherwise it seems like most of the queries where collation setting is required would have to be extended.

Piotrek Karaś	Friday 05 October 2007 11:17:28 am I dug a bit, did some experimenting, unfortunately no results. MySQL seems to unfailingly adhere to the priorities of server->database->table->column default collation override system and I haven't found a way to make it change its behavior by any SQL request upon establishing DB connection. Query rewriting seems inevitable for my purpose and I really hope I am wrong about it. Anyone with greater MySQL experience?
