Nested Table in Reports

Using Oracle 8i and Reports 6i
I looked at the few Reports forum items on this subject but wonder if someone could give me more detailed information.
Among the tables in my database I have an invoice table with an invoice number, booking number and a nested table of user-defined item objects.
I want to create a Group Above report with Name, Address and other customer information on Level 1, and the list of charges from the Invoices table below followed by a simple total of charges.
Can I do this in Report Builder with a nested table? With the nested table you seem to lose the Master-Detail relationship between tables, since for every booking there is one invoice, but of course the nested table contains potentially many items.
I understand that the Report Wizard does not support nested tables, so do I need to base the report on a single, very complex SQL query? In that case, am I not losing the advantages of an application like Report Builder since I'm back with the limitations of SQL aggregate functions, namely SUM?
In every case, the results of my query will produce one invoice. Can I manually place the results of the query in the Reports layout using text boxes, as in the Oracle document Building an Invoice Report (http://otn.oracle.com/products/reports/htdocs/getstart/docs/B10310_01/orbr_invoice.htm) but I'm not sure if I can do the same thing in Oracle 8i.
Thank for your help.

There should be no problems doing this. Since the data and the layout are separate the version of the database and the features being used have little impact on the layout in this way.
Hope this helps,

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?

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.

Associative Array to Nested Table: Anything faster?

(First Post! Some ASP.NET references, but I think this really is a PL/SQL question)
I work on a team that runs an Oracle instance for data warehousing and reporting along with an ASP.NET based website for display.
Sometimes, I may want to have many parameters come in and only show records that match those parameters. For example, I may want to show all employees who are Managers or Developers and not show employees who are Accountants or Scientists. Typically, I send a parameter into my PL/SQL stored procedures as an associative array (as declared in my package specification). Once in the procedure, I convert that associative array into another associative array (as a user created SQL type) and then I'm able to use it like a nested table to join on.
My question is: in your experience, is there any way to get around this type conversion or another faster way?
For example:
-- Create the sql type
CREATE OR REPLACE TYPE DIM.sql_string_table AS TABLE OF VARCHAR2(255);
--pretend that this works and it's in a package body
declare
type string_table is table of varchar2(255) index by binary_integer;
l_job_types string_table; -- Keep in mind I'd normally be sending this via ASP.NET
l_job_types_nested sql_string_table := sql_string_table();
begin
-- Add some data
l_job_types(0) := 'Manager';
l_job_types(1) := 'Developer';
-- Do the conversion
for i in l_job_types.first .. l_job_types.last
loop
l_job_types_nested.extend;
l_job_types_nested(l_job_types_nested.count) := l_job_types(i);
end loop;
-- get some data out (we're pretending)
open fake_ref_cursor for
Select e.*
from employees e,
the(select cast(l_job_types_nested as sql_string_table) from dual) jobs_types_wanted
where e.type = value(jobs_types_wanted);
end;
The result would be all employees whose have a type that was input into the l_job_types associatve array.
See: http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:110612348061
for additional reference

> I convert that associative array into another associative array (as a user created SQL type)
Just so we're clear, Oracle use the term 'associative array' to refer to the exclusively PL/SQL sparse collection type ("table of x index by pls_integer" etc) as distinct from the common nested table collection type.
Also I could be wrong but I think
SELECT ..
FROM the(select cast(l_job_types_nested as sql_string_table) from dual) jobs_types_wantedis generally the same as
SELECT ..
FROM TABLE(l_job_types_nested) jobs_types_wantedthough "SELECT *" and implicitly collection casting don't always mix. The "THE()" syntax is deprecated.

How to delete the NULL entries in nest table

Hi,
After I used a loop and open/fetch cursor populated the object table
I found there are random NULL entries in my object table (nest table)
The data look like this
NULL NULL           NULL
NULL NULL           NULL
123     03-MAY-04     ACTIVE
NULL NULL           NULL
NULL NULL           NULL
234     21-MAY-04     ACTIVE
NULL NULL           NULL
345     11-MAY-04     ACTIVE
NULL NULL           NULL
How can I get rid of those NULL entries in my nest table? So it can become
123     03-MAY-04     ACTIVE
234     21-MAY-04     ACTIVE
345     11-MAY-04     ACTIVE
Additional info:
create type myType as object
(id NUMBER (10,0),
eff_date date,
status VARCHAR2(17)
create type myNestTab as table of myType;
I have tried Delete procedure in following two ways.
Version 1:
FOR i IN l_my_nest_tab.FIRST..l_my_nest_tab.LAST
LOOP
IF l_my_nest_tab(i).id IS NULL THEN
l_curr_event_tb.DELETE(i);
               END IF;
END LOOP;
Version 2:
FOR i IN l_my_nest_tab.FIRST..l_my_nest_tab.LAST
LOOP
IF l_my_nest_tab(i) IS NULL THEN
l_curr_event_tb.DELETE(i);
               END IF;
END LOOP;
Both of them give me the error no data found. And only left me the first NOT NULL entry in the table.
123     03-MAY-04     ACTIVE
Thanks in avdance.

Hi Vishnu,
u can write a report program for this and in that use the event :
AT NEW <field-name> ( use primary key)
your statements
ENDAT
for eg.
loop at itab ( herfe itab must be of type of table for which u want to track new entries)
at new matnr
write:/ new record
endat
endloop.
schedule this report in background to run in every 5 or 10 mins as per your requirement and hence changes can be tracked.
regards
Vinod

Inserting Data into nested table

I am exploring the differences between OBJECT & RECORD.
As i am still in process of learning, I found that both are structures which basically groups elements of different datatypes or columns of different datatypes, one is used in SQL and other is used in PL/SQL, please correct me if I am wrong in my understanding.
Below i am trying to insert data into an table of type object but i am unsuccessful can you please help.

So only purpose of equivalent SQL types concept of nested tables is to use them as one of the data types while defining an actual table?
Sort of - you can definitely use them for more than just "defining an actual table". (I'm fairly certain you could pass a nested table into a procedure, for example - try it, though - I'm not 100% sure on that - it just "makes sense". If you can define a type, you can use it, pass it around, whatever.).
Ariean wrote:
And that nested table could be a record in SQL or an Object in PLSQL or just simple datatype(number,varchar etc)?
Nested tables are just like any other custom data type. You can create a nested table of other data types. You can create a custom data type of nested tables.
It could get stupidly .. er, 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's starting to hurt - I hope you get the idea

10g Nested Tables and APEX

Trying to use the following within Apex:
CREATE TYPE location_typ AS OBJECT (
location_id NUMBER(4),
street_address VARCHAR2(40),
postal_code VARCHAR2(12),
city VARCHAR2(30),
state_province VARCHAR2(25));
CREATE TYPE nt_location_typ AS TABLE OF location_typ;

countries nt_country_typ)
NESTED TABLE countries STORE AS nt_countries_tab (
(PRIMARY KEY (NESTED_TABLE_ID, country_id))
ORGANIZATION INDEX COMPRESS
NESTED TABLE locations STORE AS nt_locations_tab);
Can get Apex to function in the Tabular Report mode by modifying the query to use the correct syntax:
select "REGION_ID",
"REGION_NAME",
c.COUNTRY_ID,
c.COUNTRY_NAME,
l.LOCATION_ID,
l.STREET_ADDRESS, l.POSTAL_CODE,
l.CITY,
l.STATE_PROVINCE
from "#OWNER#"."REGION_TAB", TABLE(COUNTRIES) C, TABLE(LOCATIONS) L
Built a 'Maintenance' form. Put the Region base column on it. Then built a tabular form (with an updateable query) on the same page to access the first level Nest ( countries). Haven't figured out how to actually edit the values yet, but feel comfortable I will.
But - trying to provide editing to the 2nd level nested table elements creates a problem. First, only 1 updateable query can be on a page. Hmmm - so to get around this I guess I have to build a new page that the calling updateable query will access when selecting one of the tabular form elements. Not elegant by any means. Was hoping to provide a blank form on the right side that would be populated by the Location Nested Table values when a select was made on the first level nest. Oh well.
Just curious how anyone has handled this? I could pass stack between pages for sure, but was hoping page regions would be sufficient to handle this.
Any white papers on this? Anything in the DEMO area to use as a template? The default Demo doesn't provide this based on querying user objects.
Thanks,

Do nested tables conflict with ?split-by-page-break:? -getting blank pages

I have an RTF template with multiple levels of groupingwith sub-totals and pagebreaks at several levels. I'm using nested tables to keep the lowest level group together. The nested table works fine as far as keeping the rows together - if a group doesn't fit on a page, it is pushed to the next page; however, it has created some blank pages in the report. The first time I report the lowest level group details, if they don't fit on one page, I get a blank page followed by the data. Each time the lowest level group changes, this may or may not occur depending on the amount of data.
If you have come across this before or have some suggestions, I would really appreciate a response. I've been working on this for quite some time and have run out of things to try.
The template is quite complex and the XML very long, so I won't post. However I can email them to you if you'd like to take a look.
Thank you for your help,
Tam
Edited by: Tam_11 on Nov 19, 2009 2:42 PM

Thanks for replying.
Yes, I tried removing the <?split-by-page-break:?> and using MS hard page break (ctrl-enter) and that doesn't work either. My totals moved to a separate page by themselves and I'm still getting the blank pages.
<?split-by-page-break:?> did exactly what it was supposed to until I added in the nested tables. It's very possible that I did something wrong with my nested tables (only my second XML report). Does anyone have a sample with nested tables that they would be willing to share?

Nested Table columns and ADF BC 11.1.2

I'm thinking ahead to a new application design, including a new database design. In this application, there are users who may not change the production tables directly, but their changes must be approved (and possibly modified) before they are applied to the production tables. The production tables are part of an existing system, and are fairly well normalized, with a master table and several detail tables.
So for the new design, I want to have a staging table, mirroring the master table, where user changes are stored until they are approved and applied to the production tables. The staging table contains a few extra columns for "add, change or delete", user who submitted the change, date the change was requested. After applying the change, the staging record is to be copied to a change history table, and deleted from staging. That way, the staging table never has a lot of data in it.
Here's the question:
I need to deal with the detail tables. I could have staging versions of each detail table, but I was thinking that it might be easier to handle if the detail tables were included as nested table columns of the master staging table. Most of the detail tables only contain a few rows per master row. But can ADF BC 11.1.2 handle nested table columns? Is it easy to use in an application?

Thanks for the quick response. I was thinking I might get a response from someone who had tried it, so I didn't waste time trying it myself. I consider your response is pretty authoritative, and I'll take that as a sign that I should forget the nested tables design.
No, polymorphic views probably won't do the job. I think I'll just go ahead and create staging versions of each detail table with foreign keys back to the master staging table. Then I'll let the wizard create the needed association objects and view links in ADF BC. It will complicate the procedure for applying changes, particularly adding a row to the change history table. But that's the price we'll need to pay.
OTOH - I just had a thought - since the change history table is mostly for auditing, it appears in some reports, but has no CRUD in the application, other than the insert when the changes are applied. If I did that insert with a trigger or some other PL/SQL, then the change history could still be a single table with nested table columns for the details.

Madhu,
I am totally amazed. I didn't think any of the MULTISET operations would work with NTs of records. Lucky you!
As for the EXCEPT, well, clearly it is a restriction or bug in PL/SQL.
You may want to report it to Oracle Support.

Hello Danny and welcome to the forum,
are you trying to insert data into a table which has a collection as a column ?
The phrase nested table was very misleading (at least for me), also the code you posted was kinda incomplete.
I could not follow the code you posted, alternately I am posting some sample code with the DDL and insert statements for your understanding.
create or replace type emp_obj as object
ejob varchar2(100),
comm number,
edeptno number
create table employee
(ename varchar2(50),
empno number,
esal number,
edetails emp_obj
/Populating the employee table with INSERT :
insert into employee values ('KING',7839,5000,emp_obj('PRESIDENT',0,10));
insert into employee values ('BLAKE',7698,2850,emp_obj('MANAGER',0,30));Now, querying the table for all columns with SELECT :
ENAME     EMPNO     ESAL     EDETAILS.EJOB     EDETAILS.COMM     EDETAILS.EDEPTNO

but the problem is when i m trying to use that object of nested table into the datablock of the form it is not been added to item list of that block.
so what is the proper way to use these type of objects to the form.
all ideas are welcomed and vry much required.
pls give example if possible so easy to understand or have any demo form related to above case then pls post me to my id i.e [email protected]
thank u all and expecting some expert solutions

Hello Francois Degrelle...

will u pls me that form to my i.e [email protected] pls mail all the detail u have regarding using nested tables to forms and reports
lots of thanks to u n advance.

JSP: DispalyTag - Nested table and rows

Hi!
I�d like to know if it�s possibile create new row with dispalytag.
I have a nested table (and long list), but I�d like to have the items under the header, not items in a column of the header. I tried with <tr> but doesn�t work.
Is it possibile to creat a row? And how??? I thought I must use decorators (org.displaytag.model.Row) but when I run my application it doesn't work.
Can you help me?
Thanks
Annalisa

Thanks for the quick response. I was thinking I might get a response from someone who had tried it, so I didn't waste time trying it myself. I consider your response is pretty authoritative, and I'll take that as a sign that I should forget the nested tables design.
No, polymorphic views probably won't do the job. I think I'll just go ahead and create staging versions of each detail table with foreign keys back to the master staging table. Then I'll let the wizard create the needed association objects and view links in ADF BC. It will complicate the procedure for applying changes, particularly adding a row to the change history table. But that's the price we'll need to pay.
OTOH - I just had a thought - since the change history table is mostly for auditing, it appears in some reports, but has no CRUD in the application, other than the insert when the changes are applied. If I did that insert with a trigger or some other PL/SQL, then the change history could still be a single table with nested table columns for the details.

Dissapearing nested tables

Please see this package, which contains INDD (CC2014, fully updated) and IDML file.
This file is an excerpt of a catalog which i'm layouting (early phase).
The table contains some nested tables. Somehow, many of these tables "dissapear". They are there, not in overset, but they aren't visible in InDesign nor when exporting to PDF.
InDesign seems to need some trigger to make them visible again, by simply cutting the text frame and pasting it again, or by typing some text in the cell which contains the inline table (doesn't always work). Using an IDML to rebuild the INDD also fixes it.
The INDD is saved with some disappeared nested tables in the right column.
So... the problem is not how to get them back, but how to prevent them from disappearing...
It happens all the time. Seems like a bug, but i'm not sure what causes it. I won't risk building the full catalog using these nested tables if they cannot be trusted.
Any ideas what is causing this behaviour?
As an alternative I could use tabbed paragraph styles instead of tables, but I prefer nested tables because of more flexible styling options (if they don't dissapear offcourse...).
Any help appreciated!

Hm, downloaded your packaged file, opened the InDesign document and the provided IDML file in CC-2014.2.
I can clearly see the problem.
Then tried to use the Story Editor Window to check what is going wrong in the InDesign table.
That crashed my CC-2014.2 instantly:

I suspect, that something in your InDesign table is very, very wrong. May be the table is corrupt.
Exporting to IDML and working on with the IDML file would be my recommendation.

Querying Nested Tables from BO

Hi,
I have a nested table [VA_GT_HC_ASIA_SGP ] in Oracle. The Inner Object in the nested table has got 4 columns, which has to be displayed in the WebI Report.
Hece I created the table as derived table in Universe by the below query.
select a.COL1, b.COL2, b.COL3, b.COL4, b.COL5 from VA_GT_HC_ASIA_SGP a, Table(a.OB_GT_HC_MAINT_INFO) b
But performance is very slow. Please advice if there exists a better way to do this.
Best Regards,
Anu

The Query is:-SELECT A.ID, A.NAME, A.COMB, B.C1,B.C2, B.C3 FROM NT_KFD_RFT_TEST_DATE A, TABLE(OB_KFD_RFT_DATA) B
Nested Table structure Example:-
ID       NAME    COMB   OB_KFD_RFT_DATA
01      TEST     ALL
The inner table (OB_KFD_RFT_DATA) structure is
C1      C2        C3
23.5   56.7   78.9
00.9   76.9   53.3
12.4   33.4   23.2
Here outer record is 01 TEST ALL, and inner record is the 3 row decimal numbers.
In Universe, I need to create Objects from C1,       C2,      C3 columns.
Currently i'm doing it with derived table (by running above query). Is there any other option to do it?
Thanks,
Anu
