Use a stored procedure to calculate the sum of 1-100 numbers that can divide 5

create procedure mypro9(out sum int)
BEGIN
	declare i int default 0;
	set sum=0;
	while i<100  do-- 循环开始
	set i=i+1;
	if mod(i,5)=0 THEN
	set sum=i+sum;
	end if;-- 结束循环
end while;-- 循环结束
end;
-- 调用存储过程
call mypro9(@sum);
-- 查询变量值
select @sum;

The results are as follows:
