Mysql之Specified key was too long; max key length is 767 bytes

mysq索引的字段都太长了，解决办法：让mysql支持比较长的索引,然后在插入表的时候，添加ROW_FORMAT=DYNAMIC ，自动格式化索引。

数据库层面的修改

show variables like 'innodb_large_prefix';
show variables like 'innodb_file_format';--修改最大索引长度限制
set global innodb_large_prefix=1;
set global innodb_file_format=BARRACUDA;
-- 添加
set global innodb_file_format_max=BARRACUDA;

建表语句的修改（直接使用navicat就不需要了）

-- 修改插入sql的语句添加ROW_FORMAT=DYNAMIC
create table idx_length_test_02
(id int auto_increment primary key,name varchar(255)
)
ROW_FORMAT=DYNAMIC default charset utf8mb4;
