使用Mysql存储过程批量插入数据

需求：在不改变现有数据的情况下，插入N条数据；

实例表：

mysql> desc student;
+------------+-------------+------+-----+---------+-------+
| Field      | Type        | Null | Key | Default | Extra |
+------------+-------------+------+-----+---------+-------+
| id         | int(10)     | NO   | PRI | NULL    |       |
| name       | varchar(20) | NO   |     | NULL    |       |
| sex        | varchar(4)  | YES  |     | NULL    |       |
| birth      | year(4)     | YES  |     | NULL    |       |
| department | varchar(20) | YES  |     | NULL    |       |
| address    | varchar(50) | YES  |     | NULL    |       |
+------------+-------------+------+-----+---------+-------+

创建语句:

DROP TABLE IF EXISTS `student`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `student` (
  `id` int(10) NOT NULL,
  `name` varchar(20) NOT NULL,
  `sex` varchar(4) DEFAULT NULL,
  `birth` year(4) DEFAULT NULL,
  `department` varchar(20) DEFAULT NULL,
  `address` varchar(50) DEFAULT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `id` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
/*!40101 SET character_set_client = @saved_cs_client */;

--
-- Dumping data for table `student`
--

LOCK TABLES `student` WRITE;
/*!40000 ALTER TABLE `student` DISABLE KEYS */;
INSERT INTO `student` VALUES (901,'张老大','男',1985,'计算机系','北京市海淀区'),(902,'张老二','男',1986,'中文系','北京市昌平区'),(903,'张三','女',1990,'中文系','湖南省永州市'),(904,'李四','男',1990,'英语系','辽宁省阜新市'),(905,'王五','女',1991,'英语系','福建省厦门市'),(906,'王六','男',1988,'计算机系','湖南省衡阳市');
/*!40000 ALTER TABLE `student` ENABLE KEYS */;
UNLOCK TABLES;

创建存储过程：

DROP PROCEDURE IF EXISTS proc_i_loop;  
DELIMITER ;;
CREATE PROCEDURE proc_i_loop(IN loop_times INT)  
BEGIN  
DECLARE var INT DEFAULT 0;
  
set var = (select count(*) from student);  
select var;  
set loop_times=loop_times+var;

WHILE var<loop_times DO  
SET var=var+1;  
INSERT INTO student(id,name,sex,birth,department,address) VALUES (var,CONCAT('test',var),'男',1999,'法律系',NULL);  
END WHILE;  
END  
;;
DELIMITER ;

执行插入:

call proc_i_loop(100000);
