我要评论通过phpmyadmin ，创建procedure，
用于生成测试数据。
随机的用户名及手机号。
delimiter $$
create procedure `sp_insert_test_users`(in `para_count` int)
begin
declare p_username varchar(50);
declare p_countrycallingcode varchar(10) default '86';
declare p_phone varchar(20);
declare p_all_phone varchar(20);
declare p_create_time datetime;
declare p_index int default 0;
declare p_userid int default 0;
if para_count > 0 then
set p_create_time = now();
while p_index < para_count do
select concat(
substring('abcdefghijklmnopqrstuvwxyz', rand()*26 , 1),
substring('abcdefghijklmnopqrstuvwxyz', rand()*26 , 1),
substring('abcdefghijklmnopqrstuvwxyz', rand()*26 , 1),
substring('abcdefghijklmnopqrstuvwxyz', rand()*26 , 1),
substring('abcdefghijklmnopqrstuvwxyz', rand()*26 , 1),
substring('abcdefghijklmnopqrstuvwxyz', rand()*26 , 1),
substring('abcdefghijklmnopqrstuvwxyz', rand()*26 , 1),
substring('abcdefghijklmnopqrstuvwxyz', rand()*26 , 1)
) into p_username;
select concat(
'139',
substring('1234567890', rand()* 10 , 1),
substring('1234567890', rand()* 10 , 1),
substring('1234567890', rand()* 10 , 1),
substring('1234567890', rand()* 10 , 1),
substring('1234567890', rand()* 10 , 1),
substring('1234567890', rand()* 10 , 1),
substring('1234567890', rand()* 10 , 1),
substring('1234567890', rand()* 10 , 1)
) into p_phone;
if not exists ( select 1 from users where username = p_username or phone = p_phone )
and length(p_username) = 8 and length(p_phone) = 11
then
set p_all_phone = concat(p_countrycallingcode,';',p_phone);
insert into `users`
(`username`, `countrycallingcode`, `phone`, `_phone`,
`group`, `created_at`, `updated_at`)
values
(p_username,p_countrycallingcode,p_phone,p_all_phone,
'user', p_create_time, p_create_time);
select @@identity into p_userid;
insert into `users_test_mock`
(`userid`,`username`, `countrycallingcode`, `phone`)
values
(p_userid,p_username,p_countrycallingcode,p_phone);
set p_index = p_index + 1;
end if;
end while;
end if;
end$$
delimiter ;
调用：
call sp_insert_test_users(10);
