有这样的问题吗? cursor不能放在程序包主体最后来实现,事这样的吗?
create or replace package toyspack as
procedure UpdateToyPrice;
function AvgToyPrice return number;
--cursor pri_cur return my_toys%rowtype;
end toyspack;
create or replace package body toyspack as
cursor pri_cur return my_toys%rowtype is
select * from my_toys;
procedure UpdateToyPrice is
pri number;
begin
select price into pri from my_toys where id= '1 ';
end;
function AvgToyPrice return number is
ave number;
begin
select avg(price) into ave from my_toys;
return ave;
end;
end toyspack;
--cursor pri_cur return my_toys%rowtype is
select * from my_toys; 这个一定要在第一个的,是吗?
------解决方案--------------------应该是放在前面,因为这只是游标的定义,并不是实际打开了。
