MySQL报错this is incompatible with sql_mode=only_full_group_by
1、报错信息
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: In aggregated query without GROUP BY, expression #2 of SELECT list contains nonaggregated column 'd.total_rated_power_transformer'; this is incompatible with sql_mode=only_full_group_by
2、修改配置文件
(1)找到配置文件my.cfg
find / -name "my.cnf"
(2)修改配置文件
vi /etc/my.cnf
加一行 sql_mode=STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
如果原本有sql_mode,去掉ONLY_FULL_GROUP_BY
3、重启mysql使配置生效
service mysqld restart
