执行这个存储过程怎么没有查出来值呢？我在mysql front下测试无值？

CREATE DEFINER=`root`@`localhost` PROCEDURE `GetDetail`(in view_id int,
in user_id int)
begin

declare nTemp int;
set nTemp = 0;
update user_count set user_count = user_count + 1 where user_id=view_id;
if user_id<>0 and view_id<>user_id then
select user_view_id into nTemp from user_view where user_viewuser_id=user_id and user_id=view_id;
if nTemp <> 0 then
update user_view set user_view_time=now() where user_view_id=nTemp;
else
insert user_view(user_id,user_viewuser_id) values (view_id,user_id);
end if;
end if;
select * from User_Search_Detail where user_id=view_id;
end


=================================================================================
单条SQL语句在front测试可以取出值来；
select * from User_Detail where user_id=view_id;
