I've got a nested table issue..

Okay, first off: in Oracle 9i is there an option to nest a table inside a nested table? I got the impression it is an option; & I'd like further info on this.
..& on to the issue I've got: I've got one nested table object that I've identified in the following way:
Create Type InnerNestedTable_ty as Object (
ID Number(10),
InnerNestedTableField Number(10)
Create Type InnerNestedTable_tab as Table of InnerNestedTable_ty;
If I were only going to nest this inside of one outer table, I'd input the following (I guess):
Create Table Info (
ID Number(10),
OuterTableField InnerNestedTable_tab
Nested Table OuterTableField Store as InnerNestedTable_ntab;
Only thing is I'd like to nest this inside a nested table, in a field of an outer table (i.e., I'm going for a nested nested table, in other words). I guess I need the code to input in order for this to occur. For example, the outer table would be called OuterTable, the field would be OuterTableField. In that field I'd like a nested table [OuterNestedTable_ty, OuterNestedTable_tab] with the fields ID & OuterNestedTableField. The OuterNestedTableField field is to be a nested table itself [InnerNestedTable_ty, InnerNestedTable_tab]. I've got the latter, but no idea Long postings are being truncated to ~1 kB at this time.

Noel,
You can check out examples in the online doc at http://download-west.oracle.com/docs/cd/B10501_01/appdev.920/a96594/adobjbas.htm#462243.

Nested table issue.

Hi All,
my oracle version is
Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - Production
PL/SQL Release 11.1.0.6.0 - Production
CORE     11.1.0.6.0     Production

i have created 2 types
lets say Typ_a , Typ_B
this 2 types used in Table_A
create table Table_A
RNo number,
Rname Varchar2(50),
Typ1 Typ_a,
Typ2 Typ_b
NESTED TABLE Typ1 STORE AS Typ_adata,
NESTED TABLE Typ2 STORE AS Typ_Bdata ;
Now i want to use same types in my other tables.
is it possible ??
i got following error
ORA-02320: failure in creating storage table for nested table column Typ1
ORA-22913: must specify table name for nested table column or attribute.

Yes. But you need to change the "segment" name where the data gets stored:
CREATE OR REPLACE TYPE Typ_a AS TABLE OF VARCHAR2(30);
CREATE OR REPLACE TYPE Typ_b AS TABLE OF NUMBER(2);
create table Table_A
RNo number,
Rname Varchar2(50),
Typ1 Typ_a,
Typ2 Typ_b
NESTED TABLE Typ1 STORE AS Typ_adata,
NESTED TABLE Typ2 STORE AS Typ_Bdata;
create table Table_B
RNo number,
Rname Varchar2(50),
Typ1 Typ_a,
Typ2 Typ_b
NESTED TABLE Typ1 STORE AS Typ_adata2,
NESTED TABLE Typ2 STORE AS Typ_Bdata2;
select * from user_segments where segment_name like 'TYP_%';

Issues with Nested Tables and Adobe Designer

Hi,
I have some strange issues when I am trying to create a nested dynamic table with SAP DATA in Adobe Designer.
My Outer Table has article items and in this table I got a nested charges. For instance the table contains this data:
DATA
|->Article1
|--->charge111
|--->charge211
|
|->Article2
|--->charge122
|--->charge222
Now I am trying to display the data in a Adobe Designer table. But if I create a table with a row article and a repeating row charge all charges will be displayed under the first Article.
This is the result:
DATA
|->Article1
|--->charge111
|--->charge211
|--->charge122
|--->charge222
|
|->Article2
How can I solve this issue? I tried to select data binding on charges like article.DATA.charges.DATA[*] but this don't work.
Anyone an idea?

Alex,
Is it print based form or interactvie form.
ABAP
If it is printbased form and if you are designing from SFP, you can use the following solution.
You have to create a nested table in the context as below.
say Table1-> Article ( fields: ARTICLENAME,....other fields) info Table2->cost info(fields:ARTICLENAME,Charge...,other fields).
The 2 tables should contains data as beow.
Table1 data.
1row->Article1 -.....other values.
2row->Article2 -.....other values.
3row->Article3 -.....other values.
Table2 data.
1row->Article1 -Charge11 .....other values.
2row->Article1 -Charge12 .....other values.
3row->Article1 -Charge13 .....other values.
4row->Article2 -Charge21 .....other values.
5row->Article2 -Charge22 .....other values.
6row->Article2 -Charge23 .....other values.
7row->Article3 -Charge31 .....other values.
8row->Article3 -Charge32 .....other values.
9row->Article3 -Charge33 .....other values.
In the context drag table2 into the table1 and define where clause on ARTICLENAME.
In the layout drag nested table in the body page and make alignments.
If your requirement is interactive, may be you can use the similar logic.

Issue with Mulidimensional Nested Table

Hi All,
I am studing Multidimensional Nested table and have the below code:
DECLARE
TYPE table_type1 IS TABLE OF INTEGER;
TYPE table_type2 IS TABLE OF TABLE_TYPE1;
table_tab1 table_type1 := table_type1();
table_tab2 table_type2 := table_type2(table_tab1);
BEGIN
FOR i IN 1 .. 2
LOOP
    table_tab2.extend;
    table_tab2(i) := table_type1();
    FOR j IN 1 .. 3
    LOOP
      IF i = 1
      THEN
        table_tab1.extend;
        table_tab1(j) := j;
      ELSE
        table_tab1.extend;
        table_tab1(j) := 4 - j;
      END IF;
        table_tab2.extend;
      table_tab2(i)(j) := table_tab1(j);
      DBMS_OUTPUT.PUT_LINE('table_tab2(' || i || ')(' || j || '): ' ||
                           table_tab2(i) (j));
    END LOOP;
END LOOP;
exception
when others then
    dbms_output.put_line(sqlerrm);
END;
This code is working fine as of now.But,If i comment below code(table_tab2 is also extended latter):
table_tab2.extend;
    table_tab2(i) := table_type1();
then it gives me error 'Subscription Beyond count'.
I would like to know why i need to extend table_tab2 twice?
Thanks!

This code is working fine as of now
No, it isn't. Make sure you have serveroutput on. If you do, you get this as script output (I am using SQL Developer):
anonymous block completed
...meaning no exception was raised to client, because you trapped it, but the DBMS Output window gives:
ORA-06533: Subscript beyond count
...with no indication of which line, because you suppressed it (why?). If you drop the worse than useless exception handler, you get:
ORA-06533: Subscript beyond count
ORA-06512: at line 22
06533. 00000 - "Subscript beyond count"
*Cause:    An in-limit subscript was greater than the count of a varray
           or too large for a nested table.
*Action:   Check the program logic and explicitly extend if necessary.
A bit more helpful, yes? and with less code. Here is a revised block that writes the loop variable product to the nested array, with its output, initialising and extending correctly:
DECLARE
TYPE table_type1 IS   TABLE OF INTEGER;
TYPE table_type2 IS   TABLE OF table_type1;
table_tab1            table_type1;
table_tab2            table_type2 := table_type2();
BEGIN
FOR i IN 1..2 LOOP
    table_tab1 := table_type1();
    FOR j IN 1..3 LOOP
      table_tab1.extend;
      table_tab1(j) := i * j;
    END LOOP;
    table_tab2.extend;
    table_tab2(i) := table_tab1;
END LOOP;
FOR i IN 1..table_tab2.COUNT LOOP
    FOR j IN 1..table_tab2(i).COUNT LOOP
      DBMS_OUTPUT.PUT_LINE('Row ' || i || ' element ' || j || ' = ' || table_tab2(i)(j));
    END LOOP;
END LOOP;
END;
Row 1 element 1 = 1
Row 1 element 2 = 2
Row 1 element 3 = 3
Row 2 element 1 = 2
Row 2 element 2 = 4
Row 2 element 3 = 6
You could alternatively dispense with table_tab1 if you prefer, and write directly each element.

Data pump import error with nested tables

So the problem is somewhat long :)
Actually the problems are two - why and how oracle are treating OO concept and why data pump doesn't work?
So scenario for the 1st one:
1) there is object type h1 and table of h1
2) there is unrelated object type row_text and table of row_text
3) there is object type h2 under h1 with attribute as table of row_text
4) there is table tab1 with column b with data type as table of h1. Of course column b is stored as nested table.
So how do you think - how many nested tables Oracle will create? The correct answer is 2. One explicitly defined and one hidden with system
generated name for the type h2 which is under type h1. So the question is WHY? Why if I create an instance of supertype Oracle tries to adapt
it for the subtype as well? Even more if I create another subtype h3 under h1 another hidden nested table appears.
This was the first part.
The second part is - if I do schema export and try to import it in another schema I got error saying that oracle failed to create storage table for
nested table column b. So the second question is - if Oracle has created such a mess with hidden nested tables how to import/export to another
schema?
Ok and here is test case to demonstrate problems above:
-- creating type h1 and table of it
SQL> create or replace type h1 as object (a number)
2 not final;
3 /
Type created.
SQL> create or replace type tbl_h1 as table of h1;
2 /
Type created.
-- creating type row_text and table of it
SQL> create or replace type row_text as object (
2    txt varchar2(100))
3 not final;
4 /
Type created.
SQL> create or replace type tbl_row_text as table of row_text;
2 /
Type created.
-- creating type h2 as subtype of h1
SQL> create or replace type h2 under h1 (some_texts tbl_row_text);
2 /
Type created.
SQL> create table tab1 (a number, b tbl_h1)
2 nested table b
3 store as tab1_nested;
Table created.

Tom Kyte has said it repeatedly ... I will repeat it here for you.
The fact that Oracle allows you to build object tables is not an indication that you should.
Store your data relationally and build object_views on top of them.
http://www.morganslibrary.org/reference/object_views.html
If you model properly, and store properly, you don' have any issues.

Nested tables and multiset operators in Oracle 10g

Consider the following scenario:
We have two identical relations R and S defined as:
CREATE TABLE R(
a INTEGER,
b table_type)
NESTED TABLE b STORE as b_1;
CREATE TABLE S(
a INTEGER,
b table_type)
NESTED TABLE b STORE as b_2;
where table_typ is defined as
CREATE TYPE table_typ AS TABLE OF VARCHAR2(8);
Suppose we have two instances of R and S, each having one tuple as follows: R(1,table_typ('a','b')) and S(1,table_typ('b','c')).
I would like to "merge" these two simple instances (e.g., achieve the effect of a simple SELECT * FROM R UNION SELECT * FROM S query) and obtain the following resulting instance: Result(1,table_typ('a','b','c')).
Would this be possible in Oracle 10g? A simple UNION does not work (I got a "inconsistent datatypes: expected - got SCOTT.TABLE_TYP" error). I also took a look at the MULTISET UNION operator over nested tables available in Oracle 10g, but it doesn't seem to get me anywhere. Any help on this would be greatly appreciated.
Thank you,
Laura

Nested tables in RTF templates

Hi,
I've developed several templates including nested tables(to display parent/child transactions together in a single column group, displaying all the detail transactions but the parent only once), in PDF output this looks fine. However the users want all their output in Excel, this same layout is not picked up by Excel(all column headers for the data in the nested table move to the right, while all the data in the nested table is grouped under a 'merged cell' column header). Output of BI Publisher reports in Excel is generally terrible with a template designed for publishing in PDF, usually I can solve this with a lot of tweaking but haven't found a solution for this issue yet. Has anyone else run into this formatting issue and may have a tip to solve this?
Regards,
Arthur

Hi,
You need to declare a TYPE object as and then use it in the table structure.
CREATE TYPE type_emp IS TABLE OF VARCHAR2(15);
CREATE TABLE Biscuits Company SA
(company_name COMPANY NOT NULL,
Company_Owner VARCHAR2(20) NOT NULL)
NESTED TABLE staff_tab STORE AS type_emp;
Please see the link for more info.

Page break on nested table

Hi,
I am getting blank page because of page break after nested table.
When page is full with the records then because of nested table, it added one space after that.
Has anyone faced this issue before?
Thanks

Hi,
Upload the .rtf template and XML sample so we can see your issue.
Also I recommend you to review our page-break document:

Problem in creating a nested table

Hi i am working on Oracle 10g and cleint is sqlplus.
Now while creating a nested table following error occured.
This is the script for your reference.:
CREATE OR REPLACE TYPE sec_pwd_hist_table
AS
TABLE OF sec_pwd_history_type
index by binary_integer
Warning: Type created with compilation errors.
SQL> show error
Errors for TYPE SEC_PWD_HIST_TABLE:
LINE/COL ERROR
0/0 PL/SQL: Compilation unit analysis terminated
3/1 PLS-00355: use of pl/sql table not allowed in this context
Please help on this issue
Regards,
Vikas Kumar

> but i want to know just one thing why its working when i am removing "INDEX BY binaty_integer"
Vikas, I trust I answered that question when I said? :
"Do not confuse the two. Do not attempt to use PL/SQL array struct definition syntax in the SQL engine for defining an ADT collection. Which is why I referred you to the manual to see how an ADT is defined in SQL."
In other words, you are trying to apply a PL/SQL concept and PL/SQL syntax to a definition of a data type in SQL.
SQL is not PL/SQL.
SQL ADTs are not PL/SQL arrays/tables.
It is not even a syntax issue - it is a basic concept issue. SQL does not support PL/SQL arrays/tables. Period.

Partitioned nested table error while dropping one partition

All,
I created a partitioned table which is also a nested table as you can see below. I got FK constraint error while attempting to drop a partition, however, I could not find the FK in order to disable it since it's underlying table emp_list_p which is not visiable to applications. How could I drop the partition in this case?
Thanks,
Jianhui

If you look closely, there is a unique index on dept_p. Oracle does not advertise it.
One of the options is that you may have to delete the rows in the partition first,
then drop the partition.

Error while mapping two times nested table

Hi,
I have a Product table which has nested ProductSubcategory in it.
ProductSubcategory nested table also has nested table ProductCategory inside it.
So there is a nested table inside nested table.
I designed a dimension on warehoue builder and while mapping, i got "ORA-22913: must specify table name for nested table column or attribute" error.
I mapped nested tables before with using varray iterator and expand object, but they were nested once. Is there any solution for mapping two or more time nested tables?
Now i exracted tables and i continuou working but, i wondered is there any way.
Creation codes are below. Thanx :)
CREATE TABLE PRODUCT
(     PRODUCTID NUMBER NOT NULL ,
     ProductSubcategory ProductSubcategory,
     MODIFIEDDATE DATE NOT NULL)
NESTED TABLE ProductSubcategory STORE AS ProductSubcategory_TABLE
( NESTED TABLE ProductCategoryId STORE AS ProductCategory_TABLE);
CREATE TYPE TYPE_ProductSubcategory AS OBJECT (
     ProductSubcategoryID number ,
     ProductCategoryId ProductCategory ,
     Name Varchar(50) ,
     rowguid varchar2(100) ,
     ModifiedDate date );
CREATE TYPE TYPE_ProductCategory AS OBJECT (
     ProductCategoryID number ,
     Name Varchar(50) ,
     rowguid varchar2(100) ,
     ModifiedDate date );

Hi,
I agree with u...I am not sure of the environment the user has so i put forth all the 3 option that crossed my mind that time....thats why i said he has to choose what best suits him/her...
Also if the database is huge and we create physical temp tables (option 2 and ur idea) its like having redundant data in the database which is also a problem....So ist upto the user to actually evaluate the situation and come up with what best suits him/her...
Regards
BharathHi,
I understand your opinion. But I am not sure that the user have enough experience to choose the best option by his one. And about the redundant data: because of this I wrote that he should truncate the tables after the last mapping which loads all data into the real target table.

Inserting data with the help of nested table...!!!

The following block is giving error
ORA-06502: PL/SQL: numeric or value error
the signature and signature_bkp have the same structure
So, can anybody help me out to solve this issue :
for copying records from one table to another table
Thanking You advancely
DECLARE
CURSOR c1
IS
SELECT *
FROM signature
WHERE creation_time > TRUNC ( SYSDATE ) - 100
AND ROWNUM < 102;
TYPE sig_typ IS TABLE OF signature%ROWTYPE;
sig_t sig_typ;
BEGIN
OPEN c1;
FETCH c1
BULK COLLECT INTO sig_t;
CLOSE c1;
FORALL i IN sig_t.FIRST .. sig_t.LAST
INSERT INTO signature_bkp
VALUES sig_t ( i );
COMMIT;
END;
--DKar

Or whether a INSERT statement with SELECT clause will do that for youby using this technique, it took 47:08:45 to copy 7252 rows
and by using a cursor for loop took 49:03:23 to copy 13567 rows
So there was appox. 40% increase in performance by using pl/sql. I thought it could be even faster using the bulk-bind ing features and nested tables.
OR i just want to know ....how to correct the block of code that was given in my 1st msg without changing its logic.
Thanks
