MySQL配置檔案關於字符集的設定

 [mysql]

default-character-set=gbk      從MySQL5.6開始系統所有的字符集都預設為utf8，這裡個人設定為gbk

character-set-server=gbk     預設的字符集

collation_server = gbk_unicode_ci   伺服器字符集校對規則

==========當前MySQL伺服器字符集設定=========

mysql> show variables like 'character_set_%';
+--------------------------+----------------------------------+
| Variable_name            | Value                            |
+--------------------------+----------------------------------+
| character_set_client     | gbk                              |
| character_set_connection | gbk                              |
| character_set_database   | gbk                              |
| character_set_filesystem | binary                           |
| character_set_results    | gbk                              |
| character_set_server     | gbk                              |
| character_set_system     | utf8                             |
| character_sets_dir       | /usr/local/mysql/share/charsets/ |
+--------------------------+----------------------------------+
8 rows in set (0.00 sec)
=========檢視庫現有的字符集==============
mysql> show variables like '%char%';
+--------------------------+----------------------------------+
| Variable_name            | Value                            |
+--------------------------+----------------------------------+
| character_set_client     | gbk                              |
| character_set_connection | gbk                              |
| character_set_database   | gbk                              |
| character_set_filesystem | binary                           |
| character_set_results    | gbk                              |
| character_set_server     | gbk                              |
| character_set_system     | utf8                             |
| character_sets_dir       | /usr/local/mysql/share/charsets/ |
+--------------------------+----------------------------------+
8 rows in set (0.00 sec)
=========顯示某資料庫的字符集============
mysql> show create database olivia;
+----------+----------------------------------------------------------------        |
+----------+----------------------------------------------------------------+
| olivia   | CREATE DATABASE `olivia` /*!40100 DEFAULT CHARACTER SET gbk */ |
+----------+----------------------------------------------------------------+
1 row in set (0.00 sec)
========顯示某資料表的字符集設定=========
mysql> show create table shangdian;
+-----------+--------------------------------------------------------------------------------------------------------------------------------+
| Table     | Create Table                                                                                                                   |
+-----------+--------------------------------------------------------------------------------------------------------------------------------+
| shangdian | CREATE TABLE `shangdian` (
  `riqi` int(11) DEFAULT NULL,
  `sal` varchar(20) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=gbk |
+-----------+--------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)
===========修改資料庫字符集===============
說明；alter database + 資料庫名 + default character set 'UTF8';
===========修改資料表字符集===============
說明:alter table + 表名 + default character set 'UTF8';


set names gbk;臨時設定字符集
