SELECT c.TNAME
FROM score a,course b,teacher c
WHERE a.CNO=b.CNO
AND b.TNO=c.TNO
GROUP BY a.CNO
HAVING COUNT(a.CNO)>5

错误：error : Expression #6 of SELECT list is not in GROUP BY clause and contains nonaggregated column ‘billing.view_dat_sdr_201903.source‘ which is not functily dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

查询后发现是因为“sql_mode=only_full_group_by”导致出错

1、通过cmd更改sql_mode

set global sql_mode=‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION‘;

重启后还是会恢复

2、更改配置文件my.ini

原安装文件里没有，自己在根目录下新建

[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8 
[mysqld]
#设置3306端口
port = 3306 
# 设置mysql的安装目录
basedir=D:\mysql\mysql-8.0.11-winx64
# 设置mysql数据库的数据的存放目录
datadir=D:\mysql\mysql-8.0.11-winx64/data
# 允许最大连接数
max_connections=200
# 服务端使用的字符集默认为8比特编码的latin1字符集
character-set-server=utf8

sql_mode=‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION‘

重启依然有效。OK！
