做项目过程中遇到需要插入有序的测试数据，不想写php循环，网上找到方法，复习了一遍存储过程了哈哈。
SQL语句参考自 https://stackoverflow.com/questions/26981901/mysql-insert-with-while-loop
delimiter $$
CREATE PROCEDURE myproc()
BEGIN
DECLARE i int DEFAULT 9;
WHILE i <= 1000 DO
INSERT INTO test_tbl (test_url) VALUES (concat('https://test.com/test',i));
SET i = i + 1;
END WHILE;
END$$
delimiter ;
call myproc();
drop procedure myproc;
