insertion in a nested table of pl/sql

worm 10.2.0.3

I know that I can do this in the example with a big collect but in the 'real' code, I have to be inserted...

My question is how to insert in a nested table of pl/sql?
create or replace type all_obj_obj as object(owner varchar2(30),object_name varchar2(30),object_type varchar2(30))
/

create or replace type all_obj_list as table of all_obj_obj
/

declare
 coll  all_obj_list := all_obj_list();
begin
 insert into table(coll) select owner,object_name,object_type from all_objects;
end;
/
I know that could do a select master, object_name, object_type bulk collect in coll but I do an insert for some reason as long as I can go in... anyway to do it?

Your "nested table" is not a "nested table" but a collection, a varable.
Obviously so can not INSERT in a memory structure.
Your need is not supposed, as BULK COLLECT would do the tric.
As you cannot disclose why you ' need; for this (you do not have) and also do not mention a version, as you ' assume; PL/SQL does not ever change or everyone uses the same version, no additional help is possible.

  • What is the preferred means of data transmission as a type of record between the nested table of pl/sql program or an associative array

    What is the preferred means of data transmission in the associative array of the nested table record vs

    Choose between Nested Tables and associative arrays

    The two nested tables and associative arrays (formerly index - by tables) use similar index notation, but they have different characteristics when it comes to persistence and ease of passing parameters.

    Nested tables can be stored in a column of data, but can of associative arrays. Nested tables can simplify the SQL operations where you would normally join a single-column table with a larger table.

    Associative arrays are appropriate for relatively small lookup tables where the collection can be constructed in memory whenever a procedure is called or a package is initialized. They are good for the collection of the information volume is unknown beforehand, because there is no fixed limit on their size. Their index values are more flexible, as associative array indices can be negative, can be no sequential and can use values of string instead of numbers.

    PL/SQL automatically converts between the bays of the host and the associative arrays that use values of digital keys. The most effective way to move the collections to and from the database server is to implement data values in associative arrays, and then use these associative arrays with erections in bulk (the FORALL statement or BULK COLLECT clause).

    So the only purpose of the equivalent concept of SQL types of nested tables is to use one of the data types when you define an actual table?

    So-you can certainly use more that a simple "set an actual table. (I'm fairly certain that you can pass a table nested within a procedure, for example - try it, though - I'm not 100% sure on that - it just 'logic'.) If you can define a type, you can use it, pass it around, whatever.).

    Ariean wrote:

    And this nested table could be a record in SQL or object in PLSQL or simple data type (varchar number, etc.)?

    Nested tables are just like any other type of custom data. You can create a nested table of other types of data. You can create a custom of nested tables data type.

    Stupidly, he could become... uh, stupid O_0

    CREATE TYPE o_myobj1 AS object ( id1   number, cdate1  date );

CREATE TYPE t_mytype1 AS table of o_myobj1;

CREATE TYPE o_myobj2 AS object ( id2   number,  dumb  t_mytype1 );

CREATE TYPE t_dumber AS table of o_myobj2;

    O_0

    OK, my brain is starting to hurt - I hope you get the idea

    It seems that in this case is called merge operation. If existing records (check primary key) are not there then it will be inserted on the other update. Check the syntax of the query that is created. It looks like she may have a supplement "). If you want to only insert then call insert operation and not merge.

    Actually, no.
    All content of the nested table is first removed (for the given FK), then the result of the MULTISET UNION is reinserted.

    How to assign values to the nested table and passes as a parameter for the procedure?

    Here are the object and its type

    create or replace type test_object1 as an object
    (
    val1 varchar2 (50).
    val2 varchar2 (50).
    VARCHAR2 (50) val3

    GRANT ALL ON test_object1 to PUBLIC;


    GRANT ALL ON test_type1 to PUBLIC;


    GRANT ALL ON test_object2 to PUBLIC;


    GRANT ALL ON test_type2 to PUBLIC;

    Here is the table object type:

    create the table test_object_tpe
    (
    sl_num NUMBER,
    Description VARCHAR2 (100),
    main_val1 test_type1,
    main_val2 test_type2
    )


    NESTED TABLE main_val1 STORE AS tot1
    NESTED TABLE main_val2 STORE AS earlier2;


    -----------------------------------------------------------------------------------------------------------

    Here is the procedure that inserts values into the nested table:

    PROCEDURE INSERT_TEST_DATA (sl_num in NUMBER,
    Description in VARCHAR2,
    p_main_val1 IN test_type1,
    p_main_val2 IN test_type2

    END LOOP;

    -------------------------------------------------------------------------------------------

    Here are the block anonymoys what values attributed to the object type and pass values in the procedure:

    Thanks for posting the DOF and the sample code but whenever you post provide your Oracle version 4-digit (result of SELECT * FROM V$ VERSION).

    Well you do almost everything bad that could be hurt.

    Here is the code that works to insert data into your table (the procedure is not even necessary).

    declare
p_sl_num NUMBER := 1001;
p_description VARCHAR2(50) := 'Testing Val1';
inval1 test_type1 := test_type1();
inval2 test_type2 := test_type2();
begin
inval1.extend();
inval1(1) := test_object1('testx1', 'testx2', 'testx3');
inval2.extend();
inval2(1) := test_object2('testy1', 'testy2', 'testy3');

INSERT INTO test_object_tpe
(
sl_num,
description,
main_val1,
main_val2
)
VALUES
(p_sl_num, p_description, inval1, inval2);
commit;
end;
/

    See example 5-15 making reference to an element of nested Table Chapter 5 using PL/SQL collections and records in the PL/SQL doc
    http://docs.Oracle.com/CD/B28359_01/AppDev.111/b28370/Collections.htm#CJABEBEA

    1. you don't even have the procedure because it is a simple INSERTION in the table you can do directly (see my above code)

    inval1(1).val1 := 'testx1';

    Since you have not yet created all the elements, there is no element 1 "inval1". You need EXTEND the collection to add an element

    inval1.extend();

    And then, there is an empty element, but "inval1" is a container for objects of type 'test_object1' not for scalars as "val1", "val2", and "val3".
    If you can not do

    inval1(1).val1 := 'testx1';

    You must create an instance of 'test_object1 '.

    inval1(1) := test_object1('testx1', 'testx2', 'testx3');

    And so on for the other collection

    You don't need the procedure (as my code example shows), but once you fill in the variables correctly it will work.

  • order of the elements in the nested tables

    In PL/SQL when I add item to a nested table of objects one by one (in order), and then try to insert that litter table type to a physical table, the change element order. How can I avoid this behavior?

    When you use the columns collection or object tables, nested tables are not guaranteed to hold the control element. varraying arrays (varrays), however, are.

    Also note that if you use the view object (or with columns in the collection), your SQL view materializes the collection and you can return any desired way (whether or not it is classified).

    I hope this helps...
