MySQL如何利用存储过程快速生成100万条数据详解

1.在测试的时候为了测试大数据量的情况下项目的抗压能力我们通常要创造一些测试数据那么现在这个方法绝对好用

其中可能会有sql空间的报错可以自己尝试解决，这里做了分批插入，每次插入30万条，所以没有遇到类似的空间问题

首先，创建要插入100万数据的表格

创建函数

随机产生字符串

delimiter $$
create function rand_string(n int) returns varchar(255)
begin
declare chars_str varchar(100) default 'abcdefghijklmnopqrstuvwxyzabcdefjhijklmnopqrstuvwxyz';
declare return_str varchar(255) default '';
declare i int default 0;
while i < n do
set return_str =concat(return_str,substring(chars_str,floor(1+rand()*52),1));
set i = i + 1;
end while;
return return_str;
end $$

随机产生数字

delimiter $$
create function rand_num( ) 
returns int(5)  
begin   
declare i int default 0;  
set i = floor(100+rand()*10);  
return i;  
end $$
#假如要删除
#drop function rand_num;

创建存储过程

并向表中插入数据

#执行存储过程，往sdb_b2c_order表添加随机数据
delimiter $$
create procedure insert_sdb_b2c_orders(in start int(10),in max_num int(10))  
begin  
declare i int default 0;   
set autocommit = 0;    
repeat  
set i = i + 1;  
insert into sdb_b2c_orders (order_id ,seller_order_id,total_amount,final_amount,source,source_name,merchant_bn ) values
(rand_string(10) ,rand_string(10),100,100,'eleme','square',(start+i));  
until i = max_num  
end repeat;  
commit;  
end $$;
#删除
# delimiter ;
# drop procedure insert_emp;

调用存储过程进行插入数据

#插入30万条数据分几次插入
call insert_sdb_b2c_orders(700003,300000); 

结果
