## 一、问题描述 ##

运行 sql 后报错：

Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated 
    column ‘day_offset’ which is not functionally dependent on columns in GROUP BY clause; 
    this is incompatible with sql_mode=only_full_group_by...

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。）

## 二、解决方法 ##

### 2.1 临时解决 ###

执行 SQL：

select @@global.sql_mode

得到查询结果：

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

可以看到我们的 `sql_mode` 中含有 `ONLY_FULL_GROUP_BY`，因此只要将它去掉即可。

执行命令：

SET sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));

**说明：** 需要注意的是，该修改仅在该次（窗口）有效，只是临时修改。

### 2.2 永久解决 ###

#### 2.2.1 windows 用户 ####

编辑 mysql 配置文件 `my.ini`，在尾部添加以下内容，重新启动 mysql 即可：

[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

#### 2.2.2 mac/linux 用户 ####

需要编辑 `/etc/my.cnf` 文件，在尾部添加以下内容，重新启动 mysql 即可：

[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

如果该文件不存在，可以新建一个，以下为初始内容：

# Example MySQL config file for medium systems.  
      #  
      # This is for a system with little memory (32M - 64M) where MySQL plays  
      # an important part, or systems up to 128M where MySQL is used together with  
      # other programs (such as a web server)  
      #  
      # MySQL programs look for option files in a set of  
      # locations which depend on the deployment platform.  
      # You can copy this option file to one of those  
      # locations. For information about these locations, see:

        # Replication Slave (comment out master section to use this)  
        #  
        # To configure this host as a replication slave, you can choose between  
        # two methods :  
        #  
        # 1) Use the CHANGE MASTER TO command (fully described in our manual) -  
        #    the syntax is:  
        #  
        #    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,  
        #    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;  
        #  
        #    where you replace <host>, <user>, <password> by quoted strings and  
        #    <port> by the master's port number (3306 by default).  
        #  
        #    Example:  
        #  
        #    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,  
        #    MASTER_USER='joe', MASTER_PASSWORD='secret';  
        #  
        # OR  
        #  
        # 2) Set the variables below. However, in case you choose this method, then  
        #    start replication for the first time (even unsuccessfully, for example  
        #    if you mistyped the password in master-password and the slave fails to  
        #    connect), the slave will create a master.info file, and any later  
        #    change in this file to the variables' values below will be ignored and  
        #    overridden by the content of the master.info file, unless you shutdown  
        #    the slave server, delete master.info and restart the slaver server.  
        #    For that reason, you may want to leave the lines below untouched  
        #    (commented) and instead use CHANGE MASTER TO (see above)  
        #  
        # required unique id between 2 and 2^32 - 1  
        # (and different from the master)  
        # defaults to 2 if master-host is set  
        # but will not function as a slave if omitted  
        #server-id       = 2  
        #  
        # The replication master for this slave - required  
        #master-host     =   <hostname>  
        #  
        # The username the slave will use for authentication when connecting  
        # to the master - required  
        #master-user     =   <username>  
        #  
        # The password the slave will authenticate with when connecting to  
        # the master - required  
        #master-password =   <password>
