修改mysql中字符集

在操作数据库中通常会遇到数据库编码问题 如gbk和utf8编码不一致等
这时候我们可以通过下面的方式查看字符集

mysql> show variables like ‘%character%’;
±-------------------------±--------------------------------------------------------+
| Variable_name | Value |
±-------------------------±--------------------------------------------------------+
| character_set_client | gbk |
| character_set_connection | gbk |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | gbk |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | C:\Program Files\MySQL\MySQL Server 5.7\share\charsets\ |
±-------------------------±--------------------------------------------------------+
8 rows in set, 1 warning (0.00 sec)

查看后我们看到有的是gbk，有的是utf8，这时我们可以进行设置全部为utf8
但是这个character_set_filesystem不要改 这个为二进制。

通过MySQL命令行修改:（编码可选）

mysql> set character_set_client=utf8;

mysql> set character_set_connection=utf8;

mysql> set character_set_database=utf8;

mysql> set character_set_results=utf8;

mysql> set character_set_server=utf8;

mysql> set character_set_system=utf8;

mysql> set collation_connection=utf8;

mysql> set collation_database=utf8;

mysql> set collation_server=utf8;

这样我们就把字符集改了。结果如下
mysql> show variables like ‘%character%’;
±-------------------------±--------------------------------------------------------+
| Variable_name | Value |
±-------------------------±--------------------------------------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | C:\Program Files\MySQL\MySQL Server 5.7\share\charsets\ |
±-------------------------±--------------------------------------------------------+
8 rows in set, 1 warning (0.00 sec)

这时问题就解决了。
