MySql “Row size too large (> 8126)” 亲测解决

问题 ：导入mysql数据表时出现错误  ： error "Row size too large (> 8126). Changing some columns to TEXT or BLOB or using ROW_FORMAT=DYNAMIC or
ROW_FORMAT=COMPRESSED may help. In current row format, BLOB prefix of 768 bytes is stored inline."

解决方案 ：

The question has been asked on serverfault too.

You may want to take a look at this article which
explains a lot about MySQL row sizes. It's important to note that even if you use TEXT or BLOB fields, your row size could still be over 8K (limit for InnoDB) because it stores the first 768 bytes for each field inline in the page.

The simplest way to fix this is to use the Barracuda file format with
InnoDB. This basically gets rid of the problem altogether by only storing the 20 byte pointer to the text data instead of storing the first 768 bytes.

The method that worked for the OP there was:

Add the following to the 

my.cnf

 file
under 

[mysqld]

 section.

innodb_file_per_table
innodb_file_format = Barracuda

# 我的my.ini

#For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.

# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

2.新建一个查询进行如下操作将nombre_tabla改成你的表名

ALTER

 the table to use 

ROW_FORMAT=COMPRESSED

.[/code]

ALTER TABLE nombre_tabla
ENGINE=InnoDB
ROW_FORMAT=COMPRESSED
KEY_BLOCK_SIZE=8;
