Insert values from one table of objects to another table of objects - oracle

Question

I have this datatype declared and afterwards populated:
CREATE OR REPLACE TYPE CRAMER."T_CREATELINK_PORTLIST" IS TABLE OF o_CreateLink_PORTLIST;
AND
TYPE o_CreateLink_PORTLIST AS OBJECT (
PORTNAME VARCHAR2(50),
PORTID NUMBER,
ISNEWPORT NUMBER,
SHELFNAME VARCHAR2(50),
SLOTNAME VARCHAR2(50),
BANDWIDTHNAME VARCHAR2(50),
ISSELECTED NUMBER );
What I want to do is get some object/s from one table of this type to another table of same type. Something like this:
lsa_all_ports cramer.t_CreateLink_PORTLIST;
INSERT INTO lsa_filter_ports VALUES( SELECT *
FROM TABLE(CAST(lsa_all_ports AS cramer.t_CreateLink_PORTLIST)) new
WHERE new.bandwidthname = 'band2');
I'm pretty sure this syntax is wrong, but is there a simple way to do this??
Other atempts:
SELECT * INTO lsa_filter_ports
FROM TABLE(CAST(lsa_all_ports AS cramer.t_CreateLink_PORTLIST)) new
WHERE new.bandwidthname = 'band2';
ORA-06550: not enough values
lsa_filter_ports cramer.t_CreateLink_PORTLIST := cramer.t_CreateLink_PORTLIST();
INSERT INTO lsa_filter_ports
(SELECT * FROM TABLE(CAST(lsa_all_ports AS cramer.t_CreateLink_PORTLIST))
WHERE bandwidthname = 'band2');
ORA-00942: table or view does not exist

Answer 1

If I understood everything correctly You can do it like here:
declare
lsa_all_ports t_createlink_portlist :=
t_createlink_portlist( o_createlink_portlist ('abc', 1, 'band1'),
o_createlink_portlist ('def', 2, 'band2'));
lsa_filter_ports t_createlink_portlist := t_createlink_portlist();
begin
select cast(multiset(select *
from table(lsa_all_ports)
where bandwidthname = 'band2')
as t_createlink_portlist)
into lsa_filter_ports
from dual;
end;

Answer 2

You can better try to use the SELECT...INTO command to do this.
The SELECT INTO statement retrieves data from one or more database
tables, and assigns the selected values to variables or collections.
And if the table is already created and you want to insert into it then you can simply do like
insert into lsa_filter_ports
select * from o_CreateLink_PORTLIST
WHERE bandwidthname = 'band2'

Answer 3

Please see below the usage.
--Created object
create or replace TYPE o_CreateLink_PORTLIST AS OBJECT (
PORTNAME VARCHAR2(50),
PORTID NUMBER,
ISNEWPORT NUMBER,
SHELFNAME VARCHAR2(50),
SLOTNAME VARCHAR2(50),
BANDWIDTHNAME VARCHAR2(50),
ISSELECTED NUMBER );
---created table same as object
create table lsa_filter_ports (
PORTNAME VARCHAR2(50),
PORTID NUMBER,
ISNEWPORT NUMBER,
SHELFNAME VARCHAR2(50),
SLOTNAME VARCHAR2(50),
BANDWIDTHNAME VARCHAR2(50),
ISSELECTED NUMBER );
--A type of object
CREATE OR REPLACE TYPE T_CREATELINK_PORTLIST IS TABLE OF o_CreateLink_PORTLIST;
---Anonymous Block
declare
lsa_all_ports t_CreateLink_PORTLIST;
begin
INSERT INTO lsa_filter_ports
SELECT *
FROM TABLE(CAST(lsa_all_ports AS t_CreateLink_PORTLIST)) new
WHERE new.bandwidthname = 'band2';
end;
Collection to collection copy
declare
lsa_all_ports t_CreateLink_PORTLIST:= t_createlink_portlist(o_createlink_portlist ('abc', 1, 'band1'),o_createlink_portlist ('def', 2, 'band2'));
lsa_filter_ports t_CreateLink_PORTLIST:= t_createlink_portlist();
cursor cur is
SELECT *
--FROM TABLE(CAST(lsa_all_ports AS t_CreateLink_PORTLIST)) new
FROM TABLE(lsa_all_ports) new
WHERE new.bandwidthname = 'band2';
begin
for i in cur
loop
lsa_filter_ports.extend;
lsa_filter_ports(cur%rowcount) := lsa_all_ports(cur%rowcount);
dbms_output.put_line(lsa_filter_ports(cur%rowcount).PORTNAME);
end loop;
end;
