mysql如何设置不区分大小写

mysql设置不区分大小写

windows下

到安装mysql的目录，修改my.ini文件

在文件最后一行加上下面一句话

lower_case_table_names=1

说明 0：区分大小写，1：不区分大小写

效果如下

[mysqld] port = 3306 basedir=F:/mysql-5.7.21-winx64datadir=F:/mysql-5.7.21-winx64/datamax_connections=200 character-set-server=utf8 default-storage-engine=INNODB sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES [mysql] default-character-set=utf8 lower_case_table_names=1

内容扩展：

linux下

进入etc下面

cd /etc/

编辑my.cnf文件

vi my.cnf

最后一行加上下面一句

lower_case_table_names=1

效果如下
