mysql Index column size too large 超过767错误解决方案(转)

mysql在执行脚本时,报出了以下错误:

index column size too large. the maximum column size is 767 bytes
原因:
INNODB 引擎,UTF-8,主键字符串 默认最大 767,需要修改
 

解决方案:

1. 对数据库进行设置

set global innodb_file_format = BARRACUDA

set global innodb_large_prefix = ON

 

注意: 在navicat中执行成功,不清楚重启数据库是否还有效

查看是否生效

show variables like 'character%';
show variables like 'collation_%';
show variables like 'innodb_large_prefix';
show variables like 'innodb_file_format';

 

2. 对脚本进行修改,添加ROW_FORMAT=DYNAMIC

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