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.

How to use nested tables object in oracle form

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 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.

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.

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.

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
mohan

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,

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.

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 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.
Thank you very much

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.

How to fetch the data from a pl/sql table and varray, with some example

I want to fetch the data using a cursor from Pl/sql table and varry and I want to update the data.
Please provide me some example.

PL/SQL Table - please note that, right term is Associative Array.
Presumably you are referring to the 'often heated' back-and-forth that sometimes goes on in the forums when people refer to ANY PL/SQL type using a term with the word 'table' in it?
Curious that you then show an example of a nested table!
type emp_tab is table of employees%rowtype;
The 'right term' for that is 'nested table'. The following would be an 'associative array' or 'index-by table'
type emp_tab is table of employees%rowtype INDEX BY PLS_INTEGER;
Those used to be called 'PL/SQL tables' or 'index-by tables' but 'associative array' is the current term used.
Associative Arrays
An associative array (formerly called PL/SQL table or index-by table) is a set of key-value pairs. Each key is a unique index, used to locate the associated value with the syntax variable_name(index).
The data type of index can be either a string type or PLS_INTEGER.
Since the Oracle docs often use 'PL/SQL table' or 'index-by table' it isn't unusual for someone asking a question to use those terms also. Technically the types may not be 'tables' but it's clear what they mean when they use the term.
In PL/SQL the term 'nested table' is still used even though the PL/SQL collection is not really a table. SQL does have nested tables where the data is actually stored in a table. The PL/SQL 'nested table' type can be used as the source/destination of the SQL data from a nested table so that may be why Oracle uses that term for the PL/SQL type.
The doc that SKP referenced refers to this use:
Nested Tables
In the database, a nested table is a column type that stores an unspecified number of rows in no particular order. When you retrieve a nested table value from the database into a PL/SQL nested table variable, PL/SQL gives the rows consecutive indexes, starting at 1.

Using Nested Table in Select Statement

Hi all ,
Can i use the PL/SQL nested table or Varray
in the select statement as a normal table joined with other database tables.
i.e.
I have a nested table NT_1 in PL/SQL proc
i have to use this NT_1 in the select statement as
select xxx from
tab_1,
tab_2,
NT_1
where
< some conditional joins >.
Please help me in this regard.
regds
Dhananjaya.H

you can not use a varray as part of a SQL Statement in order to build joins.
Can you explain better what do you want to do ?

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) ;

Can anybody correct me.

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

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,
description,
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.
