MYSQL Character Set

How to modify the MySQL default character set: MySQL default encoding is Latin1, does not support Chinese, should be set to UTF8 to see if their database encoding is set.

1. If the MySQL installation directory, there is a suffix named:. ini configuration file, copy, modify to My.ini
2. If there is no. ini file in the MySQL installation directory, create a plain TXT file that is modified to: My.ini (note that you should see. txt before you modify it)
3. Modify the configuration file as follows:

[Client]

Default-character-set=UTF8     

[mysqld]

Character-set-Server=UTF8     

[MySQL]

Default-character-set=UTF8

Another way to modify the MySQL default character set is to use the MySQL command

2. MySQL> SET character_set_client = UTF8;
4. MySQL> SET character_set_connection = UTF8;
6. MySQL> SET character_set_database = UTF8;
8. MySQL> SET character_set_results = UTF8;
10. MySQL> SET character_set_server = UTF8;
14. MySQL> SET collation_connection = UTF8;
16. MySQL> SET collation_database = UTF8;
18. MySQL> SET collation_server = utf8;

In general, even if you set the table MySQL default character set is UTF8 and send the query through UTF-8 encoding, you will find that the database is still garbled. The problem is on the connection connection layer. The workaround is to execute the following sentence before sending the query:

1. SET NAMES ' UTF8 ';

It is equivalent to the following three-sentence instruction:

1. SET character_set_client = UTF8;
2. SET character_set_results = UTF8;
3. SET character_set_connection = UTF8;

MySQL Character set
The database system--and the database--and the table--fields can set the character set, and if subordinates each specify, use the parent's
If the table uses UTF-8 storage file, it must be UTF-8

connection is analogous to a character converter that is responsible for translating client-side writes with database encoding, as well as for database and return views. (client------>connection--->database) (database-->connection-->result)
