mysql select into方式导入导出

前提条件是要设置secure_file_priv,该参数是需要重启实例的

mysql> show variables like ‘%secure%‘;
+--------------------------+-----------------------------+
| Variable_name            | Value                       |
+--------------------------+-----------------------------+
| require_secure_transport | OFF                         |
| secure_auth              | ON                          |
| secure_file_priv         | /opt/mysql5733/secure_file/ |
+--------------------------+-----------------------------+
3 rows in set (0.01 sec)

SELECT * FROM tb_hxl01 INTO OUTFILE ‘/opt/mysql5733/secure_file/tb_hxl01.txt‘ FIELDS TERMINATED BY ‘,‘;

或是

select * into outfile ‘/opt/mysql5733/secure_file/tb_hxl0222.txt‘ fields terminated by ‘,‘ from tb_hxl01 where id=2;

导出文件内容如下
[root@localhost secure_file]# more tb_hxl01.txt

尝试导入到另外一个表
create table tb_hxl02 like tb_hxl01;


LOAD DATA INFILE ‘/opt/mysql5733/secure_file/tb_hxl01.txt‘ INTO TABLE tb_hxl02
FIELDS TERMINATED BY ‘,‘ ENCLOSED BY ‘"‘
LINES TERMINATED BY ‘\n‘;


查看表数据
