I've read thoroughly all the other questions/answers on this error before posting. I am getting the above error for the following query:

Error 1709 (hy000): Index Column Size Too Large. The Maximum Column Size Is 767 Bytes.

CREATE TABLE IF NOT EXISTS `pds_core_menu_items` ( `menu_id` varchar(32) NOT NULL, `parent_menu_id` int(32) unsigned DEFAULT NULL, `menu_name` varchar(255) DEFAULT NULL, `menu_link` varchar(255) DEFAULT NULL, `plugin` varchar(255) DEFAULT NULL, `menu_type` int(1) DEFAULT NULL, `extend` varchar(255) DEFAULT NULL, `new_window` int(1) DEFAULT NULL, `rank` int(100) DEFAULT NULL, `hide` int(1) DEFAULT NULL, `template_id` int(32) unsigned DEFAULT NULL, `alias` varchar(255) DEFAULT NULL, `layout` varchar(255) DEFAULT NULL, PRIMARY KEY (`menu_id`), KEY `index` (`parent_menu_id`,`menu_link`,`plugin`,`alias`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; Does anyone have idea why and how to fix it? The catch is - this same query works perfectly on my local machine, and worked as well on my previous host. Btw.it's from a mature project - phpdevshell - so I'd guess these guys know what they are doing, although you never know. Any clue appreciated.

Django Specified Key Was Too Long; Max Key Length Is 767 Bytes

Progress Log Contributions [13 Nov 2004 12:28] Bent Vangli Description: When I try to execute django.db.utils.operationalerror: (1071, 'specified key was too long; max key length is 767 bytes') the following SQL statement: CREATE TABLE phpgw_lang ( lang varchar(5) NOT NULL DEFAULT '', app_name varchar(100) NOT NULL DEFAULT 'common', message_id varchar(255) NOT NULL mysql max key length is 3072 bytes DEFAULT '', content text, PRIMARY KEY(lang,app_name,message_id) ); I got MySQL Error: 1071, Specified key was too long; max key length is 1000 bytes When I shorten message_id to varchar(228) it works. varchar(229) doesn't. I am using UTF8 as http://stackoverflow.com/questions/8746207/1071-specified-key-was-too-long-max-key-length-is-1000-bytes default charset on my MySQL engine. I cannot see anything wrong with above statement. However, I probarly got this error because multibyte preferable UTF8 character set uses much more bytes than the number of characters. Looking at the numbers, you find (5 + 100 + 228) * 3 = 999, which is less than 1000. and contrary (5 + 100 + 229) * 3 = 1002. I looks like MySQL are using a factor of 3, maybe hardcoded? https://bugs.mysql.com/bug.php?id=6604 But in normal western languages this is normally much less than 3 times, maybe more like 1.2 - 1.5. I Had put this on Serious Severity because it disables the possibility to install eGroupWare from http://www.egroupware.org/ using MySQL 4.1.x. With very best regards Bent Vangli PS! I do compile and install from source. If guided to sourcefiles involved, I may do some testing. How to repeat: Run above statement on a MySQL 4.1.7 with UTF8 as default charset on a Fedora Core 2 (Linux kernel 2.6). Proberly also on other OS using UTF8. Suggested fix: Suggestion 1: Add a runtime or compiler variable/setting allowing to increase this 1000 bytes limit, or suggestion 2: Count characters only, and eventually discards bytes after 1000, or suggestion 3: Add a runtime or compiler option allowing for adjusting the expected characters/bytes factor for UTF8 multibyte. [14 Nov 2004 18:54] Matt Lord Hi, Thanks for your bug report! This is not a bug, it is a stated limitation. From the manual page: http://dev.mysql.com/doc/mysql/en/CREATE_INDEX.html "Prefixes can be up to 255 bytes long (or 1000 bytes for MyISAM and InnoDB tables as of MySQL 4.1.2). Note that prefix limits are measured in bytes, whereas the prefix length in CREATE INDEX statements is interpreted as number of characters. Take this into account when specifying a prefix length for a column that uses a multi-byte character set." You are correct,

has never been a problem for me, until I started using UTF-16 as the character set for one of my databases. UTF-16 can use up to 4 bytes per character which means that in an InnoDB table, you can’t have any keys longer than 191 characters. Take this CREATE statement for example: CREATE TABLE `user` ( `id` int(11) NOT NULL AUTO_INCREMENT, `username` varchar(32) NOT NULL, `password` varchar(64) NOT NULL, `email` varchar(255) NOT NULL, PRIMARY KEY (`id`), UNIQUE KEY `UNIQ_8D93D649F85E0677` (`username`), UNIQUE KEY `UNIQ_8D93D649E7927C74` (`email`) ) ENGINE=InnoDB DEFAULT CHARSET=utf16 AUTO_INCREMENT=1 ; This will fail with an error like Specified key was too long; max key length is 767 bytes, because the UNIQUE INDEX on the email field requires at least 1020 bytes (255 * 4). Unfortunately there is no real solution to this. Your only options are to either reduce the size of the column, use a different character set (like UTF-8), or use a different engine (like MYISAM). In this case I switched the chara
