我在存储过程中有一个简单的嵌套while循环,但是它给出了一个错误。 循环并不是什么好事,只是为了学习目的,我创建了两个循环。
delimiter $$
create procedure getSum(in input int , out output int)
begin
set output = 0;
while input >= 1 do
declare tmp int default 1;
while tmp <= 5 do
set output = output + input ;
set tmp = tmp + 1;
end while ;
set input = input - 1 ;
end while;
end $$
delimiter ;
以下是错误
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'declare tmp int default 1; while tmp <= 5 do set output = output + inpu' at line 7
感谢。
答案 0 :(得分:0)
试试这个:
delimiter $$
create procedure getSum(in input int , out output int)
begin
declare tmp int default 1;
set output = 0;
while input >= 1 do
set tmp = 1;
while tmp <= 5 do
set output = output + input ;
set tmp = tmp + 1;
end while ;
set input = input - 1 ;
end while;
end $$
delimiter ;
