使用load data infile来导入导出数据

876543e

先导出数据

   
mysql> select * from timer_gps_posinfo where time>'2017-01-01 00:00' and time <'2017-01-02 00:00' into outfile '/home/posinfo.txt' fields terminated by ',';

报错：

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

解决：两种方法

1.使用

   
mysql>SHOW VARIABLES LIKE "secure_file_priv";
+------------------+-----------------------+
| Variable_name    | Value                 |
+------------------+-----------------------+
| secure_file_priv | /var/lib/mysql-files/ |
+------------------+-----------------------+
1 row in set (0.00 sec)

查看授权路径。

2.禁用secure-file-priv可通过修改配置文件生效。

再试

   
mysql> select * from timer_gps_posinfo where time>'2017-01-01 00:00' and time <'2017-01-02 00:00' into outfile '/var/lib/mysql-files/posinfo.txt' fields terminated by ',';
Query OK, 4532130 rows affected (16.18 sec)

成功导出，用时16秒。

同一台机器，起了个docker-mysql，在新mysql中建立空数据库和表结

使用

   
mysql> load data infile '/var/lib/mysql-files/posinfo.txt' into table timer_gps_posinfo fields terminated by ',';
Query OK, 4532130 rows affected (17.28 sec)
Records: 4532130  Deleted: 0  Skipped: 0  Warnings: 0

导入完成。
