MySQL數據表導出某條記錄

請按照步驟導出，不然可能會報錯：

ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement

第一步：首先進入數據庫

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爲導出路徑，必須爲這個，後邊加文件名；

第二步：導出

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」 （輸出的文件路徑）
lines terminated by 「\r\n」 （每一行都換行）

第三步：進入導出的文件路徑

root@vmware01:/var/lib/mysql-files# ls
result.txt

 # 查詢某天的數據

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";
