An error is as follows ：

Expression #2 of SELECT list is not in GROUP BY clause and contains 
nonaggregated column ‘sss.month_id’ which is not functionally 
dependent on columns in GROUP BY clause; this is incompatible with 
sql_mode=only_full_group_by

The cause of the problem ： 
MySQL 5.7.5 And the above functions depend on the detection function , If enabled ONLY_FULL_GROUP_BY SQL Pattern （ By default ）,MySQL Selection list will be rejected ,HAVING Condition or ORDER BY The query reference of the list is in GROUP BY Unnamed non set column in clause , It doesn't depend on them in function .（5.7.5 Before ,MySQL No functional dependency detected , Not enabled by default ONLY_FULL_GROUP_BY, of 5.7.5 A description of the previous behavior , Please see the “MySQL 5.6 Reference manual ”.）

Solution 1 ：

open navcat, use sql Inquire about ：

select @@global.sql_mode

The value of the query is ：

ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

Get rid of ONLY_FULL_GROUP_BY, Reset value .

set @@global.sql_mode 
=’STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION’;
