MySQL 存储过程批量插入总结

功能需求背景：今天接到产品经理核心业务表的数据压测功能，让我向核心业务表插入百万级的业务量数据，我首先想到的办法就是存储过程实现数据的批量 。

由于无法提供核心业务表，本文仅仅提供我刚刚自己创建的表bds_base_user 表做相关功能展示。

表DDL

CREATE TABLE `bds_base_user`(
    `id` varchar(64) NOT NULL,
    `age` int(11) DEFAULT'O',
    `name` varchar(64) NOT NULL,
    `amount` decimal(20,8) NOT NULL,
    PRIMARY KEY (id)
)ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;

存储过程版本1.0

create procedure proc_batch
begin
    declare i int default 0;
    declare uid varchar(64) default 
    declare uamount decimal(20，8) default 0;
    declare uage int default 0;
    declare uname varchar(64) default '';

    -- 定义SQL异常处理：主键重复
    declare continue handler for 1062 select 'duplicate key error encountered';

    -- 开启事务
    start transaction;
    -- 循环遍历
    --组装id
    select concat('1',ceiling(rand() * 9000000000 + 1000000000)) into uid;
    --组装age
    select floor(18 + (rand() * 9)) into uage;
    --组装amount
    select round((10 +(rand() * 1001)), 8) into uamount;
    --组装name
    select concat('测试账户',floor(rand()*11+10)) into uname;
   
    insert into bds _base_user(id, age, name, amount) values(uid, uage, uname, uamount);

    set i=i+1;
    if i % 1000 = 0 then
        commit;
    end if;
end while;
end

我在自己的座位上正在正常执行向核心业务表的注入数据的存储过程，产品经理火急火燎的跑过来通知我，批量注入的数据质量必须考虑。

存储过程版本2.0

目标：主要解决模拟数据的质量问题，主要体现在：姓名、电话号码、邮箱、公司名称、家庭\公司住址、字段限定取值范围（涉及字符串和整形）、金额、时间、系统主键和默认值等相关问题。

解决办法：采用自定义函数实现

自定义函数总结

集合生成和判断

-- 生成随机数1-3
select round(rand()*(3-0) + 0) from dual;

--指定集合随机获取
select el from(
select'新增' as el from dual
union all select '修改' from dual
union all select '删除' from dual
union all select '查询' from dual
)as temp
order by rand()
limit 1;

-- 判断指定字符串是否在指定集合范围内
select ifnull(count(1), 0) from(
select'新增' as el from dual
union all select '修改' from dual
union all select '删除' from dual
union all select '查询' from dual
)as temp where el ='测试'

-- 生成随机电话号码
select  concat('1',
   substring(cast(3 + (rand() * 10) % 7 AS char(50)), 1, 1),
   right(left(trim(cast(rand() AS char(50))), 11), 9));

-- 生成随机邮箱
select CONCAT( FLOOR(UNIX_TIMESTAMP()+10000000000*rand()),'@',ELT(CEILING(RAND( ) * 4) ,  "qq.com","163.com","sina.com","gmail.com"))

-- 生成随机姓名

-- 生成随机1990 后30年
SELECT date( CONCAT(CEILING(30*RAND())+1990,'-',CEILING(12*RAND()),'-',CEILING(30*RAND())) )

创建生成主键函数：

delimiter //
create function fun_id()
	returns varchar(64)
begin
		return concat('10000',SUBSTR(md5(UUID()), 5));
end //
delimiter ;

select fun_id() from dual;

MySQL 8 执行遇到的报错：

This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its declaration and binary logging is enabled (you might want to use the less safe log_bin_trust_function_creators variable)

造成原因：MySQL 服务中/my.ini 配置中log_bin_trust_function_creators 变量默认为关闭，需要设置为开启。

方式1（临时方案，MySQL服务重启会失效）
可以通过SQL语句设置，SQL语句如下：
1）查询变量值

show variables like 'log_bin_trust_function_creators';

2）设置变量值

set global log_bin_trust_function_creators = 1;

show variables like 'log_bin_trust_function_creators';

方式2（永久方案，需要重启MySQL服务，配置才能生效）
在 my.cnf 配置文件中添加如下一行配置，然后重启MySQL服务

log_bin_trust_function_creators = 1

创建随机生成家庭/公司地址函数

新增省、市、区/县和街道数据表。

-- bill.base_province definition

CREATE TABLE `base_province` (
  `id` int NOT NULL AUTO_INCREMENT,
  `code` varchar(100) NOT NULL,
  `name` varchar(100) NOT NULL,

  PRIMARY KEY (`id`)

  `province_code` varchar(64) NOT NULL,

  `id` int NOT NULL AUTO_INCREMENT,
  `code` varchar(64) NOT NULL,
  `name` varchar(64) NOT NULL,
  `arae_code` varchar(64) NOT NULL,
  `city_code` varchar(64) NOT NULL,
  `province_code` varchar(64) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=41353 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;

数据来源请参考：Administrative-divisions-of-China

核心SQL：

SELECT 
    (select p.name  from base_province p where p.code = t1.province_code) as provinceName,
	(select c.name  from base_city c where c.code = t1.city_code) as cityName,
	(select a.name  from base_area a where a.code = t1.arae_code) as areaName,
	t1.name FROM base_street AS t1 JOIN 
(SELECT ROUND(RAND() * ((SELECT MAX(id) FROM base_street)-(SELECT MIN(id) FROM base_street ))+(SELECT MIN(id) FROM base_street)) AS id) AS t2 WHERE t1.id >= t2.id  
ORDER BY t1.id LIMIT 1 ;
