MySQL创建function时出错
写了个function，结果报错，说是declare的错误，看代码应该不会有什么declare的错误啊，请大家帮忙。

SQL code

delimiter $$create function pbi_db.get_category_list() returns varchar(255)begin        declare finished default 0;        declare category_list varchar(255);        declare name varchar(50);        declare category_list_cur cursor for select name from category;        declare continue handler for not found set finished=1;        open category_list_cur;        get_name_list: loop          fetch category_list_cur into name;          if finished then                leave get_name_list;          end if          set category_list = CONCAT(category_list,",",name);        end loop get_name_list;        close category_list_cur;        return SUBSTR(list,3);end$$delimiter ;

报错：mysql> source /home/hadoop/quinton/procPractice/get_category_list.sql
ERROR 1064 (42000): 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 'default 0;

太粗心了 ，没写integer类型

这种错误就是告诉你，你的SQL语法错误了，并且通过use near '...'来标示你的SQL语法错在哪个地方。
[解决办法]
declare finished int default 0;
声明finished未指定数据类型的原因导致的。
