I get this when I go to my Special:Log... A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was: SELECT log_type, log_action, log_timestamp, log_user, user_name, log_namespace, log_title, cur_id, log_comment FROM user, logging LEFT OUTER JOIN cur ON log_namespace=cur_namespace AND log_title=cur_title WHERE user_id=log_user ORDER BY log_timestamp DESC LIMIT 0,50 from within function "". MySQL returned error "1267: Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (latin1_bin,IMPLICIT) for operation '='". I'm running the following: MediaWiki (http://wikipedia.sf.net/): 1.4beta2 PHP (http://www.php.net/): 4.3.9 (apache) MySQL (http://www.mysql.com/): 4.1.7 (I'm also using Apache 1.3.33, if that matters any) Unfortunately, I have no other info to give... It sort of is that simple tho... If I just go to the log page, that's what I get.
Ah, the joys of MySQL 4.1. :P Having built for older versions, our table definitions don't specify collations or character sets. I'm not sure what exactly we'll need to change, and under what circumstances it's a problem... Just for some extra background: is this a fresh installation of MediaWiki, or an upgrade? Is it a fresh installation of MySQL 4.1, or an upgrade from an earlier version of MySQL?

Is it a fresh installation of MySQL 4.1, > or an upgrade from an earlier version of MySQL? It never was an existing MediaWiki 1.3.8, if that's what you mean. (I started from MediaWiki 1.4beta1 (which still had the problem) and then moved to beta2. As for MySQL, I was always on 4.1...
I just tested it on another box, with a fresh install of *MediaWiki (http://wikipedia.sf.net/): 1.4beta2 *PHP (http://www.php.net/): 5.0.2 (apache) *MySQL (http://www.mysql.com/): 4.1.7 And, it had the same problem...
Running MySQL 4.1.8 gcc built binaries, along with PHP 5.0.3 with both mysql and mysqli configuration, MediaWiki seems to be working perfectly expect when accessing Special:Log. I get the same error as above, a brand new installation of 1.4 beta 6. --Paul Laudanski http://castlecops.com
In addition to Special:Log causing this error, Special:Log/delete brings it up as well. Is the Special:Log call the only one affected by this?
Created attachment 272 [details] Column format change which may fix this [HEAD] The problem seems to be that log_title is not specified as binary, whereas cur_title/page_title is. MySQL 4.0 doesn't care, but MySQL 4.1 won't let you join on those two fields (which the log display does) as it's interpreted their encodings differently. Attached is a patch which changes the column definition and adds updaters to change it in place. The updaters.inc fixes don't patch cleanly against REL1_4; it would be easy to manually copy in, or you can just run maintenance/archives/patch-logging-table.sql manually. I haven't checked this in as I don't have a 4.1 test box set up at the moment so can't confirm that it does the job, or whether the change in place is sufficient on an already running 4.1 db. (It may require dropping and recreating the table, depending on how the charset comes into things and when and how it's set. If the wrong charset 'sticks' on the alter it might requiring recreating the table, or else being more specific in the alteration.)
Tested successfully on MySQL 4.1, committed to 1.4 branch. Had already put into HEAD.
