Ways to modify the MySQL default character set

Can the MySQL default character set be modified? The answer is yes, the following will teach you two ways to modify the MySQL default character set, you want to learn the MySQL default character set can be enlightened.

(1) The simplest method of modification is to modify the character set key values in the MySQL My.ini file,

such as Default-character-set = UTF8
Character_set_server = UTF8

After the modification, restart the MySQL services, service MySQL restart

Use mysql> show VARIABLES like ' character% '; view, discover that database encoding has been changed to UTF8

+--------------------------+---------------------------------+
| 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 | D: "mysql-5.0.37" Share "charsets" |
+--------------------------+---------------------------------+
(2) Another way to modify the MySQL default character set is to use the MySQL command

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 collation_connection = UTF8;
mysql> SET collation_database = UTF8;
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:

SET NAMES ' UTF8 ';
It is equivalent to the following three-sentence instruction:

SET character_set_client = UTF8;
SET character_set_results = UTF8;
SET character_set_connection = UTF8;
