Error 1071 Sqlstate 42000 Er_too_long_key
Contents |
exceeded the limit of the maximum error 1071 (42000) specified key was too long; max key length is 1000 bytes key length. A key can not be longer than 1000 bytes
Error 1709 (hy000): Index Column Size Too Large. The Maximum Column Size Is 767 Bytes.
(767 bytes for InnoDB). Please note that this limit is set in bytes, not in characters. So if you use a multi-byte innodb_large_prefix character set, you can get this error even if the sum of column lengths is less than 1000 because column length is defined in characters. Below is an example of this: CREATE TABLE table1( str1 VARCHAR(255), str2 VARCHAR(255), str3 VARCHAR(255)) DEFAULT CHARACTER SET utf8; ALTER TABLE table1 ADD INDEX (str1, str2, str3); ERROR 1071 (42000): Specified key was too long; max key length is 1000 bytes

That exact error message is actually posted as a bug report from Nov 2004, when in fact, it is not really a bug. That should direct you on how to adjust key lengths, especially your PRIMARY KEYs. If you know which table is causing the Error 1071, you have to do the following: Step 01) mysqldump only database schema mysqldump --routines --triggers --all-databases --no-data > MySQLSchema.sql Step 02) mysqldump only data mysqldump --all-databases --no-create-info > MySQLData.sql Step 03) Using vi or some other editor, edit the table'
