MySQL使用存储过程插入100万条记录
业务上为了测试DB写入性能，需测试大量数据写入速度，数据库部署在aws上，4核8G内存100G硬盘，MySQL5.7.27
--创建测试数据库
create database a1 default charset utf8mb4;
--创建测试表
CREATE TABLE `test110` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`name` varchar(200) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`user` varchar(200) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`comp` varchar(200) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`create_time` datetime DEFAULT NULL,
`cid` int(11) DEFAULT NULL,
`aid` int(11) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
--创建插入存储过程
DELIMITER $$
CREATE PROCEDURE test_insert()
BEGIN
declare i int;
set i=0;
while i<1000000 do
INSERT INTO `test110` VALUES (null,'TMP01','user11','会员中台','2019-08-15 00:00:02','11','22');
set i=i+1;
end while;
end $$
DELIMITER ;测试如下，速度很快:
mysql> call test_insert();
Query OK, 1 row affected (44.71 sec)
mysql> call test_insert();
Query OK, 1 row affected (44.74 sec)
mysql> call test_insert();
Query OK, 1 row affected (44.71 sec)
mysql> select count(1) from test110;
