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")
