本文介绍了选择到Oracle中的临时表的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在尝试执行以下操作,
I am trying to do something like the following,
select * into temp from (select * from student);
它给了我以下错误,
ERROR at line 1:
ORA-00905: missing keyword
在我的真实示例中,子查询(select * from student)更复杂.
In my real example the subquery (select * from student) is more complex.
我想在存储过程中使用它,所以我不想创建表本身.我只想通过使用临时表使我的代码更具可读性.
I want to use this in a stored procedure, so I don't want to create the table itself. I just want to make my code more readable by using a temp table.
推荐答案
那么也许你需要做这样的事情:
Then perhaps you need to do something like this:
declare
type t_temp_storage is table of student%rowtype;
my_temp_storage t_temp_storage;
begin
select * bulk collect into my_temp_storage from student;
for i in 1..my_temp_storage.count
loop
dbms_output.put_line('here I am '||my_temp_storage(i).stuid);
end loop;
end;
