MySQL数据表导出某条记录

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";
