mysql报错

    在mysql5.7是ok的,但是高版本同样的语句有问题:
    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”。)

    ERROR 1055 (42000): Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'lms.u.USER_ID' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
