解决办法就是把ONLY_FULL_GROUP_BY去掉…

步骤

操作以下步骤的时候, 先把数据库服务停

找到配置文件示例

// 我的处理方法是比较安全的, 尽量避免使用命令
// 输入命令,打开文件夹,复制my-default.cnf到桌面
mao$ sudo open /usr/local/mysql/support-files/

将文件重命名为 my.cnf, 然后拷贝到etc/目录下, 重新启动mysql就可以了

# Remove leading # to turn on a very important data integrity option: logging

# These are commonly set, remove the # and set as required.

# datadir = .....
# port = .....
# server_id = .....
# socket = .....

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.

# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M


# 认真看, 这里配置不包含ONLY_FULL_GROUP_BY
