mysql表导出导入测试(utf8-utf8)

一.测试需求

将maridb 10.0.20下的表lots.t_order迁移到mysql 5.6中，字符集都是utf8，测试迁移后的表记录数是否与源表相同，汉字是否有乱码。
二.基本信息

1.源表环境信息：

mysql> select version();

+---------------------+

| version() |

+---------------------+

| 10.0.20-MariaDB-log |

+---------------------+

1 row in set (0.00 sec)

2.目标环境信息：

(product)root@localhost [(none)]> select version();

| version() |

+------------+

| 5.6.29-log |

+------------+

1 row in set (0.00 sec)

三.源环境导出
---导出数据库lots下的表t_order:

[apps@mvxl0781 mariadb10_data3306]mysqldump -uroot -p lots t_order >t_order.sql

[apps@mvxl0781 mariadb10_data3306]$ ls -ltr

[apps@mvxl0781 dbdat]$ ls -ltr

-rw-rw-r-- 1 apps apps 750953342 Apr 20 23:32 t_order.sql

---将导出文件通过ftp或scp复制到目标库的主机上

[apps@mvxl0781 dbdat]$ scp t_order.sql
root@10.16.24.107:/data/mysql/mysql3376/data/

root@10.16.24.107's password:

t_order.sql 100% 716MB 119.4MB/s 00:06

四.目标环境导入

---建立lots库

(product)root@localhost [(none)]> create database lots;

Query OK, 1 row affected (0.00 sec)
[mysql@mvxl0782 data]$ pwd

/data/mysql/mysql3376/data

----导入表

[mysql@mvxl0782 data]$ mysql -uroot -p -S /tmp/mysql3376.sock lots <t_order.sql
----查看表的记录数，与来源表的记录数相同

(product)root@localhost [lots]> select count(*) from t_order;

+----------+

| count(*) |

+----------+

| 1872178 |

+----------+

1 row in set (1.41 sec)
----表中记录汉字显正常

(product)root@localhost [lots]> select * from t_order limit 1,2\G

总结：

maridb 10.0.20下的表在字符集相同情况下能正常迁移到mysql 5.6中，且汉字不会乱码。
