请按照步骤导出，否则可能会报错：
ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement
第一步：首先进入数据库
mysql> show variables like '%secure%'; +--------------------------+-----------------------+ | Variable_name | Value | +--------------------------+-----------------------+ | require_secure_transport | OFF | | secure_auth | ON | | secure_file_priv | /var/lib/mysql-files/ | +--------------------------+-----------------------+ 3 rows in set (0.00 sec)
secure_file_priv为导出路径，必须为这个，后边加文件名；
第二步：导出
mysql> select idfa from firstapp_report where day_time between '2018-12-13 00:00:00.028986' and '2018-12-17 23:59:50.512468' into outfile '/var/lib/mysql-files/result.txt' lines terminated by '\r\n';; Query OK, 86329 rows affected (0.09 sec)
into outfile “c:/data_out.txt” （输出的文件路径） lines terminated by “\r\n” （每一行都换行）
第三步：进入导出的文件路径
root@vmware01:/var/lib/mysql-files# ls result.txt
# 查询某天的数据
select count(id) from firstapp_report where callback_result_text='success' and offer_id=25 and date_format(day_time,"%Y-%m-%d")="2018-12-18";
