MySQL time zone error problem and Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggre

The first question: The server time zone value'ÖÐ¹ú±ê×¼Ê±¼ä' is unrecognized or represents more than one time zone....

solution:

1. Use cmd command to query time_zone and give him +8:00

1. First enter cmd and then mysql (the instructions to enter mysql are not mentioned)

2. Enter show variables like'%time_zone%';

3. Enter set global time_zone='+8:00';

The effect chart is as follows:

Second, add a default-time-zone ='+8:00' to the my.ini configuration file in mysql

Then restart mysql and you're done~ The command mode can be used without restarting

Tip: The way to modify the configuration file needs to be placed under [mysqld], otherwise it is invalid!

The second question: 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

I tried many command methods before, but they didn't work very well. Finally, I watched the blog and modified the configuration file by myself.

The method is: find the my.ini configuration file in the mysql file, add at the end of the configuration file

[mysqld]
sql_mode=NO_AUTO_VALUE_ON_ZERO,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE

Then restart the mysql service~
