MySQL基础：存储过程（利用存储过程生成随机数据）

1.创建存储过程
右键函数，新建函数


2. 创建函数或者存储过程
填入参数

3. 填写存储过程代码

随机往aws_action表中插入数据

BEGIN
 
	DECLARE i int UNSIGNED;
	DECLARE t int UNSIGNED;
	set i=1;
	set t=1529370782;
	while i<=num DO
		if(i%50=0) then 
			set t=t+FLOOR(1+RAND()*18);
		ELSE
			set t=t+FLOOR(1+RAND()*10000);
		end if;
		insert into aws_action(item_id,user_id,start_time) values(FLOOR(11000+RAND()*60000),FLOOR(1+RAND()*17),t);
		
		set i = i + 1;
		
	end while;


END

4. 原始SQL语句

DROP PROCEDURE IF EXISTS `insertaction`;

CREATE DEFINER = `root`@`%` PROCEDURE `insertaction`(IN `num` int)
BEGIN
 
	DECLARE i int UNSIGNED;
	DECLARE t int UNSIGNED;
	set i=1;
	set t=1529370782;
	while i<=num DO
		if(i%50=0) then 
			set t=t+FLOOR(1+RAND()*18);
		ELSE
			set t=t+FLOOR(1+RAND()*10000);
		end if;
		insert into aws_action(item_id,user_id,start_time) values(FLOOR(11000+RAND()*60000),FLOOR(1+RAND()*17),t);
		
		set i = i + 1;
		
	end while;


END;
