一、查看存储过程
1.show procedure status; //查看所有的
2.show create procedure proc_AllUser[proc_name]; 查看proc_AllUser这个存储过程的具体信息
3.select 'name' from mysql.proc where db = 'test' and 'type' = 'PROCEDURE';
e.g.
select * from mysql.proc where db = 'sfjc' and type = 'PROCEDURE'; //查看存储过程
select * from mysql.pro where db = 'sfjc' and type = 'function'; //查看函数二、查看函数
1.show function status; //对比下面的，查看的信息少，只是一些状态信息
2.select * from mysql.proc where db= 'test' and type = 'function'; //可以当成查看表三、查看视图
1.select * from information_schema.VIEWS;四、查看表
1.select * from information_schema.TABLES;五、查看触发器
1.语法：SHOW TRIGGERS [FROM db_name] [LIKE expr]
实例：mysql>SHOW TRIGGERS \G; //查看触发器
（实战中加了'\G'：在客户端下没用，在cmd中操作命令可行，用于纵向显示）
e.g.
show triggers from sfjc where definer like 'bghc%'; //显示definer中以bghc开头的
show create trigger sfjc_dj_djlxr_before_update[trigger_name];
2.对INFORMATION_SCHEMA数据库中的TRIGGERS表查询
mysql>SELECT * FROM triggers T WHERE trigger_name=”mytrigger” \G
select * from triggers where trigger_name like 'sfjc_dj%';
