Question simple quue PL/SQL nested tables

Hello, my question is about nested tables. Suppose I have a nested table:
Int_array ARRAY TYPE IS INT;
v_int_array int_array;

Is there a built in function for me to v_int_array for a specific integer search value?

George

MEMBER of operator use:

declare
    TYPE int_array IS TABLE OF INT;
    v_int_array int_array := int_array(1,2,3,4,5);
begin
    if 1 member of v_int_array
      then
        dbms_output.put_line('Found it!');
    end if;
end;
/
Found it!

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).

Question about the nested Table

I created a table nested in the database type.
CREATE TYPE TT1 IS TABLE OF THE VARCHAR2 (100);
If I use this collection in my procedure and fill it with values, these values are stored in the tablespace/data files or cache. I'm asking is because I want to fill the collection with a lot of documents and collections are stored in memory and the comprehensive data set will explode memory told me.

You mention a procedure so I guess that we are talking about a nested table defined in and complemented by a PL/SQL block. If so, these data are stored in the PGA. You should be a good idea on the amount of data you have in the PL/SQL collections at any time in time, because the PGA memory is a relatively rare commodity.

If we are talking of a nested table that corresponds to a column in a normal organized in a heap table, these data are stored in data files and read the SGA according to the needs as all data in a heap table.

Nested table frees the file after validation?

Hello world
My version of DB is

NLSRTL Version 10.2.0.1.0 - Production

I have a question about the nested table. I am writing a code to change the data type for a column varchar2 to date without deleting the data.
So I thought instead of creating the table or the TWG, I will fill these data in the collection and updating of this column as null. So I'll change the data type for this column and the data that is loaded inside the collection, I'll shoot back as it is.
The collection is formed, the data are updated with the null value and data type of the column is updated as well. But when I'm trying to load the data in collection, it seems to be empty. Why is happening. ? Nested table depends on the statement commit?
Please take a look at the code and suggest me something here.

Your EXCEPTION WHILE others removes any possible EXCEPTOIN that is raised. You need to get rid of him. Or at least use RAISES at the end. And if you decide to use the collection then get the best out of him using treatment in BULK. Here is an example FORALL.

Inserting data in the nested table

I explore the differences between the OBJECT and RECORD.
As I'm still learning, I found that both are structures which essentially brings together different elements of types of different data or columns of data types, one is used in SQL and other is used in PL/SQL, please correct me if I'm wrong in my understanding.
Below, I am trying to insert data into an array of type object, but I can't can you please help.

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;

O_0

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

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.

Nested table of object type have only one record all the time
Hi all

I have a question regarding the storage of multiple records in a nested Table that is of type OBJECT.

The program below that I wrote for the test and during the test, I was able to store only the last record in the nested Table.

Please let me know what I did wrong here.

Step 1:
CREATE or REPLACE TYPE book_obj AS OBJECT (name varchar2 (25), author varchar2 (25), abstract varchar2 (4000));
/

Step 2:
CREATE or REPLACE TYPE book_table IS TABLE OF THE book_obj;
/

Step 3: CREATE TABLE book (name, varchar2 (25), varchar2 (25) author, varchar2 (4000)) abstract;
INSERT VALUES Accountants ('Harry Potter,' 'MK', 'It's magic');
INSERT the book VALUES ("Ramayana', 'VK', 'It is mythiology'");
COMMIT;

Step 4:
declare
bookset book_table;
ln_cnt pls_integer;
Start
bookset: = book_table (book_obj ('madhu', 'kongara', 'sudhan'));
dbms_output.put_line (' the number is ' | bookset.) (Count); -> I see COUNT = 1
bookset: = bookset_t(); -> Assignment to NULL.
dbms_output.put_line (' the number is ' | bookset.) (Count); -> I see County 0
for rec in (select * from book) loop-> now a loop twice.
dbms_output.put_line (' name > ' |) Rec.Name);
bookset: = bookset_t (book_t (rec.name, rec.author, rec.abstract));
end loop;
dbms_output.put_line (' the number is ' | bookset.) (Count); -> I can see COUNT = 1 (why?)
END;

I looped twice to fill two records in the TABLE IMBRIQUEE OF TYPE OBJECT. But when I see the Count I get only 1 and the data is also having the last record.

Can you get it someone please let me know how to fill out the table nested with all records. Tell me where I am wrong.

Very much appreciate your help here.

Thank you and best regards,
NKM
Maldini says:
dbms_output.put_line (' the number is ' | bookset.) (Count); -->, I can see COUNT = 1 (why?)

Because instead of add to bookset collectionto set (ergo replacement) it a collection containing recovered book. Use:
```
declare
    bookset book_table;
    ln_cnt pls_integer;
begin
    bookset := book_table(book_obj('madhu','kongara','sudhan'));
    dbms_output.put_line('The count is '||bookset.count); --> I can see COUNT =1
    bookset := book_table(); --> Assigning back to NULL.
    dbms_output.put_line('The count is '||bookset.count); --> I can see count as 0
    for rec in (select * from book) loop --> Now Looping two times.
      dbms_output.put_line(' name > '||rec.name);
      bookset.extend;
      bookset(bookset.count) := book_obj(rec.name, rec.author, rec.abstract);
    end loop;
    dbms_output.put_line('The count is '||bookset.count); --> I can see COUNT =1 (why)
end;
/
The count is 1
The count is 0
name > Harry Potter
name > Ramayana
The count is 2

    dbms_output.put_line('The count is '||bookset.count); --> I can see COUNT =1
    bookset := book_table(); --> Assigning back to NULL.
    dbms_output.put_line('The count is '||bookset.count); --> I can see count as 0
    select  book_obj(name,author,abstract)

How to fill the value in the nested table by using the object type

Hi gurus
I created an object type and able to fill the values in it, now I want to create a nested table type of this object and fill it but looks like I'm doing something wrong, see my code below.
Code example
CREATE or REPLACE TYPE countries_o
AS
OBJECT
(
COUNTRY_ID TANK (2 BYTES),
COUNTRY_NAME VARCHAR2 (40 BYTE),
REGION_ID NUMBER);
/
create or replace type countries_t is table of the countries_o;

/
CREATE OR REPLACE
ABC of the PROCEDURE
IS
v_print countries_t; -: = arr_countries_t('01','Aus',1);
BEGIN
v_print: = countries_t('01','A',11);
DBMS_OUTPUT. Put_line (v_print. COUNTRY_ID | v_print. COUNTRY_NAME | v_print. REGION_ID);
END;
/
Error
- Error (6.3): PL/SQL: statement ignored
- Error (6,12): PLS-00306: wrong number or types of arguments in the call to 'COUNTRIES_T '.
- Error (7.3): PL/SQL: statement ignored
- Error (7.32): PLS-00302: component 'COUNTRY_ID' must be declared
Thanks in advance
Concerning
Muzz

Hi user,

Here is another method that you can try-

CREATE OR REPLACE

ABC of the PROCEDURE

IS

v_print countries_t: = countries_t (countries_o('01','A',11));

BEGIN

DBMS_OUTPUT. Put_line (v_print (1).) COUNTRY_ID | v_print (1). COUNTRY_NAME | v_print (1). REGION_ID); -you're accessinf the first element of the nested table, which in turn points to the object.

END;

In the sections of the declaration you have assigned values to the nested table.

Kind regards

Format an array of multilevel nested table object in a TABLE

DB: Oracle 11 g 2
Platform: client windows 7
Hello
I have a table of multilevel nested table object.
{code}
CREATE OR REPLACE TYPE OBJ_1 AS OBJECT)
NUMBER of col_1,
col_2 VARCHAR2 (56),
col_3 VARCHAR2 (256)
);
CREATE OR REPLACE TYPE ARR_1 AS TABLE OBJ_1;
CREATE OR REPLACE TYPE OBJ_2 AS OBJECT)
NUMBER of col_4
col_5 Number (15),
col_6 NUMBER (1).
col_7 NUMBER (1).
col_8 VARCHAR2 (56),
col_arr ARR_1
);
CREATE OR REPLACE TYPE ARR_2 AS TABLE OBJ_2;
{code}
I want to convert this table format - I need to feed in a program. expected release:
--------------------------------------------------------------------------------
col_4 col_5 col_6 col_7 col_8 col_1, col_2 col_3
--------------------------------------------------------------------------------
1           2          3           4           5          1           2          3

The Toad, the following query creates the output:
{code}
Select *.
table (ARR_2 (OBJ_2 (1, 2, 3, 4, '5', ARR_1 (OBJ_1 (1,2, '3'))),))
OBJ_2 (1, 2, 3, 4, '5', ARR_1 (OBJ_1 (4.5, '6')))

{code}
Where (DATASET) is the inner nested table. So I thought I'd add a level to "function table" will do the job, but NO, mistake.
{code}
Select * from table)
Select *.
table (ARR_2 (OBJ_2 (1, 2, 3, 4, '5', ARR_1 (OBJ_1 (1,2, '3'))),))
OBJ_2 (1, 2, 3, 4, '5', ARR_1 (OBJ_1 (4.5, '6')))
);
Error: ORA-02324: more than one column in THE subquery SELECT list
{code}
Any suggestion?
Thank you.

You just need to join another TABLE operator who breast COL_ARR:

SQL > with tmp (obj) as)

2. Select (ARR_2)

OBJ_2 3 (1, 2, 3, 4, '5', ARR_1 (OBJ_1 (1,2, '3')));

4 OBJ_2 (1, 2, 3, 4, '5', ARR_1 (OBJ_1 (4.5, '6')))

5           )

6 double

7)

8. Select t2.col_4, t2.col_5, t2.col_6, t2.col_7, t2.col_8

9, t1.col_1, t1.col_2, t1.col_3

tmp 10 t

11, t2 table (t.obj)

12, t1 table (t2.col_arr)

13;

COL_4 COL_5 COL_6 COL_7 COL_8 COL_1, COL_2 COL_3

The objects have been created successfully. However when I use it in my code, I need to initialize them, but I get an error for the variable of ws_data_compare_master_tt type initialization.

I'm unable to initialize the variable g_ws_data_compare_master_tt of type ws_data_compare_master_tt that I get the below error.

Can someone help me to find out what is the problem?
Thanks in advance.
Kind regards
Natarajan

Ah, I found the problem on my own. It was because of a bad statement similarly variable g_ws_data_compare_master_tt in a table in the specification of the package that was trouble. However I wonder the error returned Oracle was not fully exposed.

Kind regards

Compare the content of two equal nested tables

I'm working on a black box test where I compare the contents of two structurally equal tables before and after executing a script of some. My two tables, MDQ_OLD and MDQ_NEW, are filled with the data in two separate operations.
The two tables, I'll compare are nested, as you can see in the CREATE TABLE scripts below.
I tried to use the less-operator sign, but without success.
I also tried to select data in a type that is % ROWTYPE to my nested tables, but it does not work as well (see the below script in this post).
Can you please help me on this problem on how to compare the content of two nested tables?
Run the scripts below to reproduce the problem and be sure to update this post if more information is required.

CREATE OR REPLACE TYPE FORCE AS OBJECT MDQ_DETAIL (NUMBER OF MDQ_DETAIL_ID, MDQ_DETAIL_DESC VARCHAR2 (100));

-Note that this type contains the table T_MDQ_DETAIL type:
CREATE OR REPLACE TYPE MDQ_PARENT FORCE AS OBJECT (NUMBER MDQ_ID, MDQ_DETAILS T_MDQ_DETAIL);
- Then I create two equal nested tables
CREATE THE NESTED TABLE AS MDQ_PR_OLD STORE MDQ_DETAILS MDQ_PARENT MDQ_OLD TABLE.
CREATE THE NESTED TABLE AS MDQ_PR_NEW STORE MDQ_DETAILS MDQ_PARENT MDQ_NEW TABLE.
-Insert test data in the nested tables
Insert into MDQ_OLD (MDQ_ID, MDQ_DETAILS) Values (1, T_MDQ_DETAIL (MDQ_DETAIL(1,'desc1')));
Insert into MDQ_NEW (MDQ_ID, MDQ_DETAILS) Values (2, T_MDQ_DETAIL (MDQ_DETAIL(1,'desc1')));
-Try to use the negative operator to compare the contents of the trailer of the nested tables, but it gives this error:

> queries you provided intercepts not who.

You asked how to compare the content of nested tables.

I knew that you didn't ask for what you actually want, that's why I asked you to specify the comparison more in detail.

> Do you have a query that grabs this difference as well?

SELECT o.mdq_id, od.*
OF mdq_old o, TABLE (o.mdq_details) od
LESS
SELECT n.mdq_id, nd.*
OF mdq_new n, TABLE (n.mdq_details) nd;

> Also, if possible, do you have a sample of a statement to COLLECT LOOSE, please?

Actually, you raise an interesting point on using % ROWTYPE, in my view, that should be. This make...

DECLARE
TYPE rt_mdq_new () IS RENDERING
mdq_id NUMBER,
mdq_details t_mdq_detail);

TYPE tt_mdq_new IS TABLE OF THE rt_mdq_new;

t_mdq_new tt_mdq_new;

DECLARE
