Ways to modify the MySQL default character set

MySQL default character set modification method may not be everyone, the following describes the two most common ways to modify the default MySQL character set, for your reference to learn.

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, found that the database encoding has been changed to UTF8

2. MySQL> SHOW VARIABLES like ' character% ';
4. +--------------------------+---------------------------------+
6. | variable_name | Value |
8. +--------------------------+---------------------------------+
10. | character_set_client | Latin1 |
12. | character_set_connection | Latin1 |
14. | Character_set_database | Latin1 |
16. | Character_set_filesystem | binary |
18. | Character_set_results | Latin1 |
20. | Character_set_server | Latin1 |
22. | Character_set_system | UTF8 |
24. | Character_sets_dir | D: "mysql-5.0.37" Share "charsets" |
26. +--------------------------+---------------------------------+
30. MySQL> SHOW VARIABLES like ' collation_% ';
32. +----------------------+-----------------+
34. | variable_name | Value |
36. +----------------------+-----------------+
38. | collation_connection | Utf8_general_ci |
40. | Collation_database | Utf8_general_ci |
42. | Collation_server | Utf8_general_ci |
44. +----------------------+-----------------+

(2) 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;
