The maximum column size is 767 bytes

ERROR 1709 (HY000): Index column size too large. The maximum column size is 767 bytes.

解决方案：

1.修改mysql

set global innodb_file_format = BARRACUDA;

set global innodb_large_prefix = ON;

set global innodb_file_per_table=ON;

查看设置结果：

show variables like 'innodb_large_prefix';
show variables like 'innodb_file_format';
show variables like 'innodb_file_per_table';

结果

innodb_large_prefix：ON

innodb_file_format：Barracuda

innodb_file_per_table：ON

2.对脚本进行修改，添加ROW_FORMAT=DYNAMIC

create table orl (........) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC;
