Specified Key Was Too Long Max Key Length Is 1000 Bytes Mysql

ERROR 1071 (42000): Specified key was too long; max key length is 767 specified key was too long; max key length is 767 bytes mysql bytes The character limit depends on the character set you use. For example if you use latin1 then the largest column

Mysql Innodb_large_prefix

you can index is varchar(767), but if you use utf8 then the limit is varchar(255). There is also a separate 3072 byte limit per index. The 767 byte limit is per column, so you can include mysql innodb increase max key length multiple columns (each 767 bytes or smaller) up to 3072 total bytes per index, but no column longer than 767 bytes. (MyISAM is a little different. It has a 1000 byte index length limit, but no separate column length limit within that). One workaround for these limits is to only index a prefix of the longer columns, but what if you want to index more than 767 bytes of a column mysql max key length in InnoDB? In that case you should consider using innodb_large_prefix, which was introduced in MySQL 5.5.14 and allows you to include columns up to 3072 bytes long in InnoDB indexes. It does not affect the index limit, which is still 3072 bytes as quoted in the manual: The InnoDB internal maximum key length is 3500 bytes, but MySQL itself restricts this to 3072 bytes. This limit applies to the length of the combined index key in a multi-column index. Read on for details and examples about innodb_large_prefix. Here are a few pre-requisites for using innodb_large_prefix: At the database level you have to use innodb_file_format=BARRACUDA At the table level you have to use ROW_FORMAT=DYNAMIC or ROW_FORMAT=COMPRESSED The default file format is still Antelope for backwards compatibility, and the default row format is COMPACT. You can set both innodb_file_format and innodb_large_prefix dynamically, but you should also set them in my.cnf so they survive a restart. Here's an example. If I try to create this table with innodb_large_prefix disabled I get an error: 1 2 3 4 5 6 7 8 mysql> create table if not exists utf8_test ( -> day date not null, -> product_id int not null, -> dimension1 varchar(500) character set utf8 collate utf8_bin

Can it be a version problem? I suspect no. If I run it with --force option, it gets even wierder: ERROR 1071 (42000) at line 807: Specified key was too long; max key length is 1000 bytes ERROR 1146 (42S02) at line 847: Table 'db.users' doesn't exist ERROR 1146 (42S02) at line 848: Table 'db.users' doesn't exist ERROR 1146 (42S02) at line 849: Table 'db.users' doesn't exist ERROR 1146 (42S02) at line 850: Table 'db.users' doesn't exist what is going on? I mean apart from solving this, I would like to understand what settings affect a simple dump-import act and why can those settings not be explicit in my dump file and be set t import. I prefer not having to debug actual errors, this must be solveable on high level. UPDATE: SOLUTION as Frederic pointed me to the right direction. Basically my dump was trying to set db with INNODB engine, but mysql on server 2 had in /etc/my.cnf [mysqld] skip-innodb by simply deleting this option and restarting mysqld, my import ran without a croak. I am very sad such a simple thing like an unavailable engine is not worthy of warning or error rather than key length issue caused by silently falling back to myISAM. Hmm. So time to switch to posgresql? mongo? :) mysql mysql-error-1071 share|improve this question edited Jun 4 '12 at 15:52 asked Jun 3 '12 at 20:52 Viktor Trón 5,8

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

The short answer is that you shouldn't be indexing such long VARCHAR columns anyway, because the index will be very bulky and inefficient. The best practice is to use prefix indexes so you're only indexing a left substring of the data. Most of your data will be a lot shorter than 255 characters anyway. You can declare a prefix length per column as you define the index. For example: ... KEY `index` (`parent_menu_id`,`menu
