======Mysql 一些設定參數======
看目前此Mysql系統 所用的字元編碼
<code>mysql> show variables like 'char%';
+--------------------------+----------------------------+
| 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       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
</code>
時常遇到有中文編碼問題只要下此指令通常都可以解決(有時候也不一定,通常字元編碼相互轉換時出現錯誤)
<code>
mysql> set names [utf8|big5|其他編碼]</code>此命令其實是修改以下與Client端相關的變數<code>character_set_client
character_set_connection
character_set_results
</code>與Mysql伺服器相關變數<code>character_set_database
character_set_server
character_set_system
</code>
