windows下mysql默认是不区分大小写的，但是linux会区分大小写，所以当执行的sql语句有大小写区别时需要注意。那么怎么设置mysql不区分大小写。1.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=1lower_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=utf8default-storage-engine=INNODB  sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES[mysql]default-character-set=utf8  lower_case_table_names=1重启mysql2.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.
