mysql

1.命令行创建 PROCEDURE

mysql> delimiter //mysql> CREATE PROCEDURE simpleproc (OUT param1 INT)    -> BEGIN    ->   SELECT COUNT(*) INTO param1 FROM t;    -> END    -> //Query OK, 0 rows affected (0.00 sec)mysql> delimiter ;

2. 中文字符显示

显示字符编码

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/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)

设置字符编码，例如

mysql> set character_set_database=utf8;

mysql>set character_set_server=utf8;

通过网页存取时，造成数据库乱码：

new String(request.getParameter("cdAlbum").getBytes("iso-8859-1"),"utf-8")
