(0030052) user1308 03-08-07 20:09 The bug is still in mysql 5, should we do something about it more than advice to not use UTF-8? Or maybe change "name" to be varchar(66)? I don't know what for the name is other than to store the "reason" word when user unsubscribe? (0040988) h2b2 (manager) 18-02-08 21:09 This fix was posted on the forum by rojaro with regard to the "Database error 1071 while doing query Specified key was too long; max key length is 1000 bytes" error message: ******** QUOTE ******** The "max key length" limitation is a known problem of MySQL. Your database is configured to use UTF-8 by default, which means that MySQL reserves 3 bytes per char instead of one byte per char. Since the max key length limit is hardcoded to 1000 bytes for MyISAM tables regardless of the currently configured

CI MySQL Sandbox MariaDB data chef Adtech Twitter GitHub RSS Using Innodb_large_prefix to Avoid ERROR 1071 If you've ever tried to add an index that includes a long varchar column to mysql max key length an InnoDB table in MySQL, you may have seen this error: 1 mysql innodb increase max key length ERROR 1071 (42000): Specified key was too long; max key length is 767 bytes The character mariadb max key length limit depends on the character set you use. For example if you use latin1 then the largest column you can index is varchar(767), but if you use utf8 then the https://mantis.phplist.org/view.php?id=8583 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 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 http://mechanics.flite.com/blog/2014/07/29/using-innodb-large-prefix-to-avoid-error-1071/ 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 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 inn

So the total bytes are 522, less than 767.

According to the response to this issue, you can get the key to apply by specifying a subset of the column rather than the entire amount. IE: ALTER TABLE `mytable` ADD UNIQUE ( column1(15), column2(200) ); Tweak as you need to get the key to apply, but I wonder if it would be worth it to review your data model regarding this entity to see if there's improvements that would allow you to implement the intended business rules without hitting the MySQL limitation. share|improve this answer edited Oct 15 '14 at 20:20 The Alchemist 2,6901017 answered Nov 29 '09 at 3:52 OMG Ponies 198k36356415 To apply by specifying a subset of the column rather than the entire amount.

Suggestion: First of all, please backup your psa and apsc database: mysqldump -uadmin -p`< /etc/psa/.psa.shadow ` --databases psa apsc | gzip > /root/manual.psa-apsc.dump.sql.gz Second, please make a command list for each database: Code: SELECT concat( 'ALTER TABLE ', table_name, ' CONVERT TO CHARACTER SET `utf8` COLLATE `utf8_bin`;' ) FROM information_schema.tables WHERE table_schema = 'psa' AND TABLE_TYPE = 'BASE TABLE' Code: SELECT concat( 'ALTER TABLE ', table_name, ' CONVERT TO CHARACTER SET `utf8` COLLATE `utf8_bin`;' ) FROM information_schema.tables WHERE table_schema = 'apsc' AND TABLE_TYPE = 'BASE TABLE' Both above SQL - queries will show a complete list of possible SQL - commands
