1、mysql存储过程变量引用

代码示例：

delimiter//
create procedure test_10()
BEGIN
	declare i int default 1;
	while (i<=10) DO
		insert into test001 (product_name) value (CONCAT('测试_',i));
		set i = i+1;
	end while;
end//
delimiter;

call test_10()
drop procedure test_10;
-- 通过concat函数，拼接字符和数字，字符和字符；
-- DELETE from test001;
