### Error querying database. Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'r2k.c1.ID
' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
这是由于mysql5.7.5以上版本默认开启
1 | only_full_group_by |
模式，对于老版本部分sql不兼容造成的，临时解决办法修改配置文件关闭
1 | only_full_group_by |
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
