ERROR 1055 (42000): Expression #1 of SELECT list is not in GROUP BY clause and contains

mysql在查询命令时出错： ERROR 1055 (42000): Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'DBname.table.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

 

解决办法：

打开数据库:mysql  -u root  -p

然后输入下列命令：

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";

重新打开数据库，问题解决。
