1-MySQL执行SQL报错

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

2-错位原因

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”。）
 

3-问题解决

一：临时修改生效

1：查看下对应的sql_mode信息

select @@global.sql_mode;
ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_I
