Row size too large (> 8126). Changing some columns to TEXT or BLOB

原文：http://stackoverflow.com/questions/15585602/change-limit-for-mysql-row-size-too-large

异常信息：

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.

解决方法：

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，ALTER the table to use ROW_FORMAT=COMPRESSED.

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

如果以上方法还不行，扩大my.ini的配置项innodb_log_file_size。之前设置的是512M，本以为足够大了，按照上述方法修改无效，然后将innodb_log_file_size扩大到1024M，就正常了。
