我已经学习了如何返回动态打开的引用游标。现在,基于输出,我想创建一个表或视图。
输入表:
copy
记录
create table sales
(s_sale_name varchar2(20),
s_date_sal date,
s_qty number(10)
);
查询输出
insert into sales values ('Norb','10-MAR-2019',10000);
insert into sales values ('Bert','10-MAR-2019',5000);
insert into sales values ('Alba','10-MAR-2019',4000);
insert into sales values ('Rob','10-MAR-2019',200000);
insert into sales values ('Norb','11-MAR-2019',5000);
insert into sales values ('Bert','11-MAR-2019',13000);
insert into sales values ('Rob','11-MAR-2019',80000);
insert into sales values ('Norb','12-MAR-2019',1000);
insert into sales values ('Bert','12-MAR-2019',4000);
insert into sales values ('Rob','12-MAR-2019',40000);
insert into sales values ('Alba','12-MAR-2019',2000);
现在,结果应保存在表或视图中。到目前为止,我已经学习了如何返回动态打开的引用游标。
------这是我使用的过程-----------
sales_name 10-MAR-2019 11-MAR-2019 12-MAR-2019
Norb 10000 5000 1000
Bert 5000 13000 4000
Alba 4000 0 2000
Rob 200000 80000 40000

这确实是一个非常不错且具有挑战性的问题。我不同意SELECT part of a CREATE TABLE ... AS SELECT statement. Well we definitely can't do that
上的@APC点。我认为,对于Oracle中的每个问题,都有一个解决方案。
您可以使用NESTED TABLE
来满足您的要求。见下文:
设置:
create table sales
(s_sale_name varchar2(20),
s_date_sal date,
s_qty number(10)
);
/
insert into sales values ('Norb','10-MAR-2019',10000);
insert into sales values ('Bert','10-MAR-2019',5000);
insert into sales values ('Alba','10-MAR-2019',4000);
insert into sales values ('Rob','10-MAR-2019',200000);
insert into sales values ('Norb','11-MAR-2019',5000);
insert into sales values ('Bert','11-MAR-2019',13000);
insert into sales values ('Rob','11-MAR-2019',80000);
insert into sales values ('Norb','12-MAR-2019',1000);
insert into sales values ('Bert','12-MAR-2019',4000);
insert into sales values ('Rob','12-MAR-2019',40000);
insert into sales values ('Alba','12-MAR-2019',2000);
---Created an Object of Sales table to hold intermediate result
create or replace type sales_obj is OBJECT
(obj_sale_name varchar2(20),
obj_date_sal date,
obj_qty number(10)
);
/
-- Table of Sales Object.
create or replace type vtest1Tab is table of sales_obj;
/
要创建表ccc
的匿名块:
DECLARE
VAR VTEST1TAB ;
vsql varchar2(500);
BEGIN
vsql := 'create table ccc(col1) NESTED TABLE COL1 STORE AS TAB1
as
Select cast(multiset(Select * from SALES) as VTEST1TAB )
from dual
';
Execute immediate vsql ;
END;
输出:
SQL> Select p.*
from ccc c,
table(c.COL1) p ;

在此link中,“ Zlatko Sirotic”的答复确切介绍了如何识别光标的列并进行打印。
查找“ dyn_fetch”,因为该软件包足够通用,因此可以与用于打印数据的任何查询一起使用。您可以使用相同的方法将数据插入动态创建的表中。
