问题现象
of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column ‘information_schema.PROFILING.SEQ‘ which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
问题原因
原因:这是数据库的sql_mode设置的有问题。Mysql可以支持不同的SQL模式,不同的SQL模式会有不同的语法,执行不同的数据校验简查。
解决方案
首先查看sql_mode
select @@sql_mode
查询出来的值为:
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
对于新创建的数据库(试过了)
去掉ONLY_FULL_GROUP_BY,重新设置值。
set @@sql_mode =‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION‘;
对于已存在的数据库(没试过)
set sql_mode =‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION‘;
或者:
在my.cnf(在/etc/mysql下)里面设置
sql_mode=‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION‘
在sql_mode 中去掉only_full_group_by
mysql建表报错(this is incompatible with sql_mode=only_full_group_by)
