  • mysql遇见Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggre的问题

    mysql遇见Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggre的问题

    Expression #2 of SELECT list is not in GROUP BY clause and contains
    nonaggregated column ‘sss.month_id’ which is not functionally
    dependent on columns in GROUP BY clause; this is incompatible with
    sql_mode=only_full_group_by

    问题出现的原因:
    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”。)

    解决方法一:

    打开navcat,

    用sql查询:

    select @@global.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

    去掉ONLY_FULL_GROUP_BY,重新设置值。

    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’;

    如下图:

    解决方法二:

    成功的步骤:

    iterm打开

    sudo vim /etc/mysql/conf.d/mysql.cnf

    滚动到文件底部复制并粘贴

    [mysqld]
    sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

    到文件的底部

    保存并退出输入模式

    sudo service mysql restart

    重启MySQL。
    完成!
