mysql批量插入测试数据

1、先创建一个数据库

create databases yang;

use yang

2、创建一个数据表

CREATE TABLE `t_user` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) DEFAULT NULL,
  `age` tinyint(4) DEFAULT NULL,
  `create_time` datetime DEFAULT NULL,
  `update_time` datetime DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

3、创建一个存储过程并调用

delimiter //
DROP PROCEDURE IF EXISTS proc_batch_insert;
CREATE PROCEDURE proc_batch_insert()
BEGIN
DECLARE pre_name BIGINT;
DECLARE ageVal INT;
DECLARE i INT;
SET pre_name=187635267;
SET ageVal=100;
SET i=1;
WHILE i <= 1000000 DO
        INSERT INTO t_user(`name`,age,create_time,update_time) VALUES(CONCAT(pre_name,'@qq.com'),(ageVal+1)%30,NOW(),NOW());
SET pre_name=pre_name+100;
SET i=i+1;
END WHILE;
END //
 
delimiter ;
call proc_batch_insert();
