1. 为了测试触发器和存储过程，首先建立一张简单的表：
CREATE TABLE `airuser` (
`userId` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(128) NOT NULL,
PRIMARY KEY (`userId`)
)ENGINE=InnoDB DEFAULT CHARSET=utf8
2. 为该表的插入操作，创建一张记录表：
CREATE TABLE `airuser_record` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(45) DEFAULT NULL,
`edittime` timestamp NULL DEFAULT NULL,
`edittype` varchar(45) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
3. 编写一个插入操作的触发器：
DROP TRIGGER insert_trigger;
delimiter |
CREATE TRIGGER insert_trigger BEFORE INSERT ON airuser
FOR EACH ROW BEGIN
INSERT INTO airuser_record SET username = NEW.username, edittime=now(), edittype='insert';
END;
SHOW TRIGGERS;
4. 为批量插入编写存储过程：
DROP procedure createUsers;
delimiter |
create procedure createUsers(IN count int)
begin
declare i int;
set i=0;
while i<count do
insert into airuser set username=concat('user_',i);
set i=i+1;
end while;
end;
show procedure status;
5. 调用存储过程，验证存储过程是工作的，并验证在插入记录前，触发器能正确被触发：
call createUsers(10);
6. 最后通过插入记录表再次验证：
SELECT * FROM mars_jpa.airuser_record;
