代码如下:
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：
代码如下:
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：
代码如下:
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：
代码如下:
DROP procedure createUsers;
delimiter |
create procedure createUsers(IN count int)
begin
declare i int;
set i=0;
while i
