mysql问题dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

报错如下：

### Error querying database. Cause: java.sql.SQLSyntaxErrorException: Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column
'yshop.yx_store_order.create_time' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

### The error occurred while setting parameters
### SQL: SELECT IFNULL(sum(pay_price),0) as num,FROM_UNIXTIME(create_time, '%m-%d') as time FROM yx_store_order where refund_status=0 and is_del=0 and paid=1 and pay_time >=
1633017600 GROUP BY FROM_UNIXTIME(create_time,'%Y-%m-%d') ORDER BY create_time ASC

which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by ;
bad SQL grammar []; nested exception is java.sql.SQLSyntaxErrorException: Expression #2 of SELECT list is not in
GROUP BY clause and contains nonaggregated column 'yshop.yx_store_order.create_time' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

问题出现的原因： 

MySQL 5.7.5及以上功能依赖检测功能。如果启用了ONLY_FULL_GROUP_BY SQL模式（默认情况下），MySQL将拒绝选择列表，HAVING条件或ORDER BY列表的查询引用在GROUP BY子句中既未命名的非集合列，也不在功能上依赖于它们。（5.7.5之前，MySQL没有检测到功能依赖关系，默认情况下不启用ONLY_FULL_GROUP_BY。有关5.7.5之前的行为的说明，请参见“MySQL 5.6参考手册”。）

解决方案：

select @@global.sql_mode
SET sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY','')); ##当前session变量生效

SET global sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY','')); ##全局变量生效

SET sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));
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';
