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-winx64

datadir=F:/mysql-5.7.21-winx64/data

max_connections=200

character-set-server=utf8

default-storage-engine=INNODB

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLЕS

[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

# For advice on how to change settings please see

# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html

[mysqld]

#

# Remove leading # and set to the amount of RAM for the most important data

# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.

# innodb_buffer_pool_size = 128M

#

# Remove leading # to turn on a very important data integrity option: logging

# changes to the binary log between backups.

# log_bin

#

# Remove leading # to set options mainly useful for reporting servers.

# The server defaults are faster for transactions and fast SELECTs.

# Adjust sizes as needed, experiment to find the optimal values.

# join_buffer_size = 128M

# sort_buffer_size = 2M

# read_rnd_buffer_size = 2M

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

# Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

lower_case_table_names=1
