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 too.

You may want to take a look at which explains a lot about MySQL row sizes. Its 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 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:

1. Add the following to the my.cnf file under [mysqld] section. innodb_file_per_table innodb_file_format = Barracuda
2. # 我的my.ini
3. #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. Its 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. [mysqld] skip-grant-tables # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. # innodb_buffer_pool_size = 128M innodb_file_per_table innodb_file_format = Barracuda # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. # log_bin # These are commonly set, remove the # and set as required. basedir ="D:/software/mysql/mysql-5.6.26-winx64" #basedir=D:softwaremysqlmysql-5.6.26-winx64 datadir ="D:/software/mysql/mysql-5.6.26-winx64/data" #datadir=D:softwaremysqlmysql-5.6.26-winx64data # port = ..... port=3306 # server_id = ..... # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M  wait_timeout=1814400   interactive_timeout=1814400   sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 
4. 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.
5. ALTER TABLE nombre_tabla ENGINE=InnoDB ROW_FORMAT=COMPRESSED KEY_BLOCK_SIZE=8;
