MySQL is using group by query error this is incompatible with sql_mode=only_full_group_by

The specific errors are as follows:

 Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'zl.tm.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

the reason:

MySQL 5.7.5 and above functions depend on the detection function. If ONLY_FULL_GROUP_BY SQL mode is enabled (by default), MySQL will reject select lists, HAVING conditions, or ORDER BY list query references that are neither named non-collection columns in the GROUP BY clause, nor are they functionally dependent on them. (Before 5.7.5, MySQL did not detect functional dependencies, and ONLY_FULL_GROUP_BY is not enabled by default.

Solution:

1. Query mysql related mode

select @@global.sql_mode;

You can see that ONLY_FULL_GROUP_BY is included in the pattern, as long as there is no such configuration. A
My MySQL version is 5.7.21, the default is with ONLY_FULL_GROUP_BY mode.

2. Reset the mode value

Set via configuration file: vim /etc/my.cnf
Add the following configuration to my.cnf (my.ini):
[mysqld]
sql_mode='The mode you want'

Such as:

sql_mode = "STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

In windows as shown:

In query mode:

There is no ONLY_FULL_GROUP_BY mode anymore.

The test sql query was successful.
