Go To D:\wamp64\bin\mysql\mysql5.7.14\my.cnf
Add following code
[mysqld]
sql_mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
