I want to create SQL data (storage structure)

scene ：
---- Upstream feeding is inconvenient , At the same time, it does not rely on the data given by the other party .
---- There are many fields in the table , It's troublesome to change every time

The way ： Write storage structure

for instance ：

SET @myCompNo=DATE_FORMAT(NOW(),'666%y%m%d%H%i%s'); --  Reading ： I don't want to make the number manually every time , It is automatically generated according to the current year, day, hour, minute and second 

--  Reading ： Table interpolation ,id The general setting cannot be repeated null,comp_no It is generated automatically above ,create_time Request generation 15 The day before ,update_time It is generally set to the current time 
INSERT INTO alibb_ses.comp_info (id, comp_no, create_time, update_time)
VALUES (null, @myCompNo, date_sub(now(),interval 15 day),now());


--  Check the made comp_no
select @myCompensatenNo;

（ Remember Ctrl A then run…… Once, one by one, the operator was stupid ）↑ This is a relatively simple example .

If you want to make something more complicated , Using a cursor, etc . For example, I want to create users ：
The first paragraph ：

create
    definer = [email protected]`%` procedure create_user(IN name varchar(50), IN a int, IN house varchar(50))
BEGIN
--  Defining variables 
DECLARE user_id bigint(15); --  This variable doesn't seem to be used 
DECLARE house_id varchar(50);
DECLARE ro_id varchar(1024);
DECLARE b int;
--  Open cursor 
SELECT bas_house_id into house_id from bas_house where house_code=house;
set b=1;
 while b<=a DO
--  Loop start 
--  Update table 
INSERT INTO `user` (`USER_ID`,…………) VALUES (username, …………);
SELECT SYS_ROLE_ID into role_id from sys_role where ROLE_NAME='admin' ;
INSERT INTO `SYS_ROLE_USER` (……) VALUES (……);
set b = b+1; 
end WHILE;
end;

The second paragraph ： call

# Make user 
CALL `create_user`('myName',1,'myHome');

# Check the data after making 
SELECT* FROM sys_user ORDER BY 1 DESC;
