首先在分组的时候出现以下的报错ERROR 1055 (42000): Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'myfile.review58.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

然后根据方法输入：

set sql_mode ='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR
_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION';

即

ok 完成

 

老师说这种有原因是因为分组时不知道取谁照成的原因。
