Performance impact using nested tables and object

Hi,
Iam using oracle 11g.
While creating a package, iam using lot of nested tables created based on objects which will be passed between multiple functions in the package..
Will it have any performance impact since all the data is stored in the memory.
How can i measure the performance impact when the data grows ?
Regards,
Oracle User

This is not client code that can lay sole claim to most of the memory. It is server code and one of many server processes that need to share the available resources. So capitalism is fine on a client, but you need socialism on the server? {noformat} ;-) {noformat}
Will it have any performance impact since all the data is stored in the memory.Interestingly yes. Usually crunching data in memory is better. In this case it may not be so. The memory used is the most expensive memory Oracle can use - the PGA. Private process memory. This means each process copy running that code, will need lots of memory.
If you're not passing the data structures by reference, it means even bigger demands on memory as the data structure needs to be copied into the call stack and duplicated.
The worse case scenario is that such code consumes so much free server memory, and make such huge demands on having that in pysical memory, it trashes memory management as the swap daemons are unable to keep up with the demand of swapping virtual memory pages into and out of memory. Most CPU time is spend by the swap daemons.
I have seen servers crash due to this. I have seen a single PL/SQL process causing this.
How can i measure the performance impact when the data grows ?Well, you need to look at the impact of your code on PGA memory. It is not SQL performance or I/O performance that is a factor - just how much private process memory your code needs in order to execute.

Using nested tables and varrays in Forms/Reports6i

Hi! Could anybody give practical examples of applications based on nested tables and varrays in Forms/Reports6i.
The possible schema of building user interface and so on.
Thank you.

Hi,
Varrays and nested tables are not supported within Forms6i and Reports6i. This means tare is no way to use it.

Varray, Nested Table and Object types in OWB r2

Requirement:
Flat file with repeating groups of nested content need to move into Object Relational ORACLE table (using varray or nested tables - no preference). The data will be loaded, then mapped/transformed into a richer O-R output to directly produce XML outputs.
Problem:
Generated PL/SQL "seems" to do the correct thing, but deployment errors show failures on mapping of collections (varrays, NTs or OTs) and in sqlplus recompiling the PKB still gives the errors. Is this a PL/SQL generator error, or is there a more meaningful example of using CONSTRUCT OBJECT operator than the embedded odcumentation - it is a simple type (single instance) and not a variable repeating group of nested data.
Anyone had any success with these, or know of any collateral to assist in the process. Thanks.

The process we are following is very simple. We are talking 10 columns from a source flat file table and wish to map this into a Varray/Nested table, with one column of Varchar2(10).
When you create your map in OWB, select the construct object, you have to choose an object type - it does not allow you to select a VARAAY or NESTED table.
I have then created an object defined in the same structure as the VARRAY/NESTED table - I have then made the VARRAY/NESTED table of this TYPE.
Example:
CREATE OR REPLACE TYPE "O_REL_PUB_INDEX" AS OBJECT (
X_REL_PUB_INDEX_1 VARCHAR2(10))
CREATE OR REPLACE TYPE "V_REL_PUB_INDEX" AS VARRAY(15) OF O_REL_PUB_INDEX
In OWB you can then select O_REL_PUB_INDEX when creating the 'Contruct Object'.
The problem I have is that when I map to my target column of type V_REL_PUB_INDEX and DEPLOY my map I get the following errors taken from OWB control centre
Name

Any ideas? anyone succesfully mapped to either a VARRAY or an NESTED TABLE target column?

Creating tabs using nested tables and templates

Hello all - Hopefully everyone had a good Easter !
is it possible to create a template of the tab structure i
want, and then insert this new template and modify the colours for
each different tab link / page link? ie, all the tabs will have the
same links but will have different colours on different pages.
you're welcome to jump on my website at
http://www.bondimigration.com.au/overview_10.html
to get an idea of what I'm talking about..

Use a server-side include for the menu on each page, give
each button a
unique ID, and use a page-specific stylesheet (either linked
or embedded) to
change the style values for the selected button.

Hello forum
How all r u ..
i need ur help guys, pls help me out...
i m using an object oriented approach to design my database by using nested tables and
varrays. it is quite done successfully.
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...
How r u doing ... i have searched the forum abt the above mentioned topic then i found that u have some demo form which will help out to explain the functionality of the nested table in forms ..
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.

Nested Tables and Advanced Queues- Please Help.

How do i work with NestedTable type and Advanced Queue.
I have done the following
I have Oracle 8.1.7 enterprise edition.
create type myType as TABLE OF varchar(32);
create type myObject as OBJECT (
id int,
myt myType);
DECLARE
BEGIN
dbms_aqadm.create_queue_table(
queue_table => 'my_queue_table',
multiple_consumers => TRUE,
queue_payload_type => 'myObject',
compatible => '8.1.3'
END;
The Nested Table and Object are created successfully.
but the queue is not created.
I get the following message.
DECLARE
ERROR at line 1:
ORA-22913: must specify table name for nested table column or
attribute
ORA-06512: at "SYS.DBMS_AQADM_SYS", line 2012
ORA-06512: at "SYS.DBMS_AQADM", line 55
ORA-06512: at line 3
I know how to specify the nested table storage clause for
create table statement, but there is no provision for
it in the create_queue_table procedure.
Any help will be greately appriciated.
i have already created and tested aqs with simple data types,
also i have created simple tables with nested table type
elements.
but the combo of Nested tables and AQ is not working.
thanks in advance.

Hi Francois. Thank you very much for your reply, but it seems that i still get errors. So let me tell what i have done.
As you suggested me: i have done a block based on a sub-query for the nested-table:
'select courses from department where name= :department.name'.
In the master block(department) i have the when-new-record-instance trigger:
Declare
LC$Req varchar2(256);
Begin
LC$Req := '(select ns.courses from table
( select courses from department where name = ''' || :DEPARTMENT.name || ''' ) ns )';
Go_block('block11');
Clear_Block ;
Set_Block_Property( 'block11', QUERY_DATA_SOURCE_NAME, LC$Req ) ;
Execute_query ;
End ;
Now the errors i receive, this time in the runtime mode are:
- FRM-41380: Cannot set the blocks query data source
-FRM-41003: This function cannot be performed here.
Since it seems that you know how to work with the nested table i would really appreaciate your help. I am new in the nested table and if you could give an ex with my tables it would be great.
Thank you in advance.

Not unless you provide the code you are actually using.
There is no definition of 'p_code_result' in your post and you say you 'trying to select data from d_table' but there is no code that loads 'd_table' in what you posted.
And the SELECT query you posted actuall selects from an object named 'l_loop_idag_code_table1' which isn't mentioned in your code.
Post the actual code you are using and all of the structures being used.
Also explain why you even need to use nested tables and PL/SQL for whatever it is you are really doing.

Nested tables and varray

hi friends,
i have a question:
why do we use nested tables and varrays?

Read the following and try to understand the examples. Try to relate them to various situations or scenarios where you can implement them. You will understand the benefits.

Nested Tables and Forms 9i-please help

Hi
i have the folowing example of a nested table:
CREATE TYPE CourseList AS TABLE OF VARCHAR2(10) -- define TABLE type
CREATE TYPE Student AS OBJECT ( -- create object
id_num INTEGER(4),
name VARCHAR2(25),
address VARCHAR2(35),
status CHAR(2),
courses CourseList) -- declare nested table as attribute
CREATE TYPE Course AS OBJECT (
course_no NUMBER(4),
title VARCHAR2(35),
credits NUMBER(1));
CREATE TYPE CourseList AS TABLE OF Course;
CREATE TABLE department (name VARCHAR2(20),
director VARCHAR2(20),
office VARCHAR2(20),
courses CourseList)
NESTED TABLE courses STORE AS courses_tab;
In Forms i have created a data block based on table department and for managing the nested table courses_tab i found out that i should use a stored procedure:
PROCEDURE procedure_nest (c_c out courses_tab%rowtype) IS
c_c courselist;
BEGIN
select c.name, c.director,office into :department.name, :department.director,
:department.office from department c , table
(select n.courses from department n where c.name =n.name and rownum<=1);
END;
compil error:
error 999 at line 1, column 35
implemntation restriction (may be temporary) ADT or schema level
collection not supported at client side with non-OCI mode.
i really would like to know what shall i do to use and manage the nested table in forms.

How to use nested tables in adobe form

Hi All,
I have to use nested tables in adobe form for table display. I have used Subforms for displaying table data. I have changed accessibility of the subforms. Currently i am able to print print the table correctly if there is single material record in table 1 and single corresponding record in table 2. But the requirement is that i will have multiple lines in table 1 for single material and only one record in table 2.
EX: form is for Sales order. in line items if the order is for 100 units then we if we have delivered material as 80, 10, 10, then table 1 will have 3 lines for this. Table 2 will always have only 1 corresponding record.
item--materialdescription-ordered qty--delivered qty--delivery date-price
xxx--xxxxxxx-xxxxxxxxx-10080xxxxxxxxxx-xxxx
10----
xxxxxxxxxx
10----
xxxxxxxxxx
yyyyyyyyyyyyyyyyyyy------yyyyyyyyyyyyyyyyyyyyy
xxxxxx is table 1 and will have multiple lines
yyyyyy is table 2 and will have only 1 entry for item xxx
and this group will be repeate as per no of items. table 1 can have any no of lines per item.
I am currently able to display 1 line for table 1 and 1 line for table 2.
But how to show multiple lines for table 1 and 1 line for table 2.

HI,
Set the body page as flowed and set the tables also flowed.
go to bodypage>object->subform-->select flowed option.
I thihnk this will work..if u are getting all the records properly into the tables 1 and 2.
Thanks,

Nested table and inner nested tables (CREATE TABLE)

Hello everyone,
I have a problem creating a table with some multilevel user-defined types (and therefore nested tables).
First of all the objects:
type top_object is object (
    text_top varchar2(100),
    table_a a_object_tbl,
    table_b b_object_tbl
type a_object_tbl is table of a_object;
type a_object is object (
text_a varchar2(100)
type b_object_tbl is table of b_object;
type b_object is object (
text_b varchar2(100),
table_c c_object_tbl,
table_d d_object_tbl
type c_object_tbl is table of c_object;
type c_object is object (
text_c varchar2(100)
type d_object_tbl is table of d_object;
type d_object is object (
text_d varchar2(100)
);Shortly: The TOP object contains tables of A and B. B contains tables of C and D.
Okay, now I want to create a table which is containing the TOP object.
My attempt:
create table multilevel_table (
some_value varchar2(100),
data top_object
NESTED TABLE top_object.table_a STORE AS data1,
NESTED TABLE top_object.table_b STORE AS data2
(NESTED TABLE table_c STORE AS data3,
NESTED TABLE table_c STORE AS data4);Obviously this does not work (otherwise I would not have been asking you ;) ). If I skip the "second level", so just by removing table_b from top_object and therefore the "inner nested table" it works.
But on this more complex scenario I don't know the right way or the syntax.
I would appreciate if I get any help or suggestions from you!

+1 for Hoek's recommendation of just not using NESTED TABLEs for persistent structures.
But:
create table multilevel_table (
some_value varchar2(100),
data top_object
NESTED TABLE data.table_a STORE AS data1,
NESTED TABLE data.table_b STORE AS data2
(NESTED TABLE table_c STORE AS data3,
NESTED TABLE table_d STORE AS data4) ;

Well you are doing almost everything wrong that could be done wrong.
Here is code that works to insert data into your table (the procedure isn't even needed).
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,

main_val1,
main_val2
VALUES
(p_sl_num, p_description, inval1, inval2);
commit;
end;
/See Example 5-15 Referencing a Nested Table Element in Chap 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 need the procedure since all it does is a simple INSERT into the table which you can do directly (see my code above)
inval1(1).val1 := 'testx1';There is no element one (1) of 'inval1' since you haven't created any elements yet. You need to 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 like 'val1', 'val2', and 'val3'.
So you can't do
inval1(1).val1 := 'testx1';You have to 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 sample code shows) but once you populate the variables properly it will work.

ALV using ABAP Classes and Objects

Hi All,
I am trying to print the values in my internal table using ALV, using ABAP classes and objects. Here the title for columns are picked based on the title specified in the data element. I want to set the title of my columns by my own. how to achieve this ?. Please provide me a sample code if possible.

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.

Unable to export nested tables and vaarys

Hai
How to export nested tables and varrays in oracle 8i (8.1.6) .When exporting nested tables and varrays not exporting .What is the advantage use of nested tables and varrays
Thanks in advance

Hello,
I think that with such a new release you should use DataPump (expdp/impdb) to
export Tables.
For exporting a complete Schema you may use the following syntax:
expdp {color:red}+user+{color}/{color:red}+password+{color} PARFILE=pfexport.txt_With pfexport.txt as bellow:_
SCHEMAS={color:red}+schema_name+{color}
FLASHBACK_TIME="TO_TIMESTAMP(to_char(SYSDATE,'DD-MM-YYYY HH24:MI:SS'),'DD-MM-YYYY HH24:MI:SS')"
CONTENT=ALL
DIRECTORY=EXP_DIR
DUMPFILE={color:red}+dump_file_name+{color}
LOGFILE={color:red}+log_file_name+{color}Then, in this example, you'll get the "dump file" and the "log file" into the EXP_DIR Oracle directory (if it exists).
You can check your Oracle Directories with the following query:
select * from dba_directories;Then, you can use one of these Directories or create a new one with the following statement
CREATE OR REPLACE DIRECTORY {color:red}+directory_name+{color} AS '{color:red}+directory_path+{color}';
GRANT READ,WRITE ON DIRECTORY {color:red}+directory_name+{color} TO {color:red}+user_name+{color};Hope it can help,
Best regards,
Jean-Valentin
