Whats a 'record group'?

Whats a 'record group'?
"To retrieve and store the contents of a list to a record group, use the RETRIEVE_LIST built-in subprogram. "
this is what i read for the retrive list built-in help doc.
but what exactly is a record group.
is it an item, a record or a lov or what?

You can think of record groups as in memory arrays. They can be an Item in your form - look at the object navigator and you'll see the record group node. But they can also be created dynamically at runtime.
More info is in the online help.

What are record groups for?

hi,
Could anybody tell me what is the main purpose of creating record groups whith statements like: create_group_from_query, populate_group, ...
Every time we want to access any records we can use blocks which are based on tables or views which are in Oracle Data Base. So what is the reason of creating record groups?
please explain my that issue:)
Grzegorz

hi grzegorz,
Record Group is one which is used with LOVs and List Items.
for the use of LOV & List items u must have to define record group through whis the List items or LOV is belogs to that group.
A record group built from a query can store records from database tables much like a database view, with the added advantage that the record group is local to Form Builder, rather than existing in the database.
To know more about record group, form builder's help is good way,

Dynamically populate a record group on the fly uisng LOV

Hi,
I want to create dynamically populate a record group on the fly uisng LOV.
1. This is how the RG_BANKNAME Record Group object look like
Object : Record Group
Name : RG_BANKNAME
Record Group Query : SELECT NAME, SHORT_NAME FROM C_BANKS
2. I create the Push Button and when user click it will popup the LOV.
DECLARE
     rg_id RecordGroup;
     errcode NUMBER;
     status BOOLEAN;
BEGIN
     rg_id := Find_Group('RG_BANKNAME');
     IF Id_Null(rg_id) THEN
          Message('No such group: ',ACKNOWLEDGE);
          RAISE Form_Trigger_Failure;
     ELSE
          errcode :=POPULATE_GROUP(rg_id);
          SET_LOV_PROPERTY('LV_NAME', TITLE, 'My Own LOV');
          SET_LOV_PROPERTY('LV_NAME', GROUP_NAME, rg_id);
          SET_LOV_COLUMN_PROPERTY('LV_NAME', 1 ,Title, 'NAME');
          SET_LOV_COLUMN_PROPERTY('LV_NAME', 1 ,Width, 150);
          SET_LOV_COLUMN_PROPERTY('LV_NAME', 2 ,Title, 'SHORT NAME');
          SET_LOV_COLUMN_PROPERTY('LV_NAME', 2 ,Width, 100);
          status := Show_LOV('LV_NAME',10,20);
          IF NOT status THEN
               Message('You have not selected a value.');
               Bell;
          END IF;
     END IF;
END;
My question is do I need to create the LOV Object name call 'LV_NAME'? since I don't have this
create on my design times, because I thought it can be done dynamically on the fly.
The problem is compliant that the Lov Id is not valid.
Thanks
David

Hello,
You request is not clear. Do you need to display the LOV or not ? In other words, what is the goal of your record group ?

Dynamically creating a Record Group based on Previously entered Record Grou

Forms [32 Bit] Version 10.1.2.3.0 (Production)
Hi,
I know how to dynamically create a record group based on a query and putting the code in When new form instance.
My query is. I have a form which has multiple Record Groups and the user wants to dynamically create subsequent groups based on previous groups.
For example
I have a record group with selects a Location,
when the user selects the Location from a list of values
the 2nd record group called 'Cost Centres' will have to filter out only those with the locations selected above.
How can I populate the 2nd record group at run-time when I do not know what site the user will select?
If I simply populate in when new form instance as in location and just select everything, the list of values populates.
CC field is a LIST ITEM and the list style is a POP LIST, it is not required.
I have put the code in the Location field in the when-list-changed trigger.
I am getting this error:
frm-41337: cannot populate the list from the record group
here is the code:
DECLARE
v_recsql Varchar2(1000); -- The SQL for creating the Record Group.
v_recgrp RecordGroup; -- Record Group
v_status Number; -- Return Value of Populate_Group function.
c_where VARCHAR2(1000);
BEGIN
     IF :location = '1' THEN
          c_where := ' substr(cost_centre,1,2) in (''01'',''02'')';
     ELSIF :location = '2' THEN
          c_where := ' substr(cost_centre,1,2) in (''02'',''03'')';
     ELSIF :location   = '3' THEN
          c_where := ' substr(cost_centre,1,2) in (''01'',''11'',''07'')';
               ELSE
          c_where := ' 1=1'; --EVERYTHING
     END IF;
v_recsql := 'SELECT cost_centre, description FROM   cost_centres where '||c_where;
-- Create the Record Group
v_recgrp := CREATE_GROUP_FROM_QUERY('v_recgrp', v_recsql);
IF NOT ID_NULL(v_recgrp)
THEN -- No Error, record group has been successfully created.
-- Populate Record Group
v_status := POPULATE_GROUP('v_recgrp');
IF v_status = 0
THEN -- No Error. Record Group has been Populated.
POPULATE_LIST('block.CC', 'v_recgrp');
END IF; -- IF v_status = 0
-- Delete the Record Group as it is no longer needed.
DELETE_GROUP('v_recgrp');
END IF; -- IF NOT ID_NULL(v_recgrp)
END;thanks for your assistance.

Hi,
Once record status gets change for block you can not populate/repopulate the list item. Keep those list items as non-database item with different names and create different items as database orignal items. Than assign the values in WHEN-LIST-CHANGE trigger to the actual database items.

Sql expressions in Forms 4.5 Record Groups

I have a record group that was asked to change, and when I change it I get an 'Unhandled exception error in icrg 102' and then a Frm-12001. I've tracked it down to a view that uses a function call to format a address line. If I put the function call in the Sql statement in the record group forms will not except the statment. I believe that the Record Groups were created in Forms 4.0.

IF v_value = 'Y'
THEN
lvl$std.copy_number(0,'BLK1.V_ITEM_NAME1');
ND IF;
I written in post-query.What does
lvl$std.copy_number(0,'BLK1.V_ITEM_NAME1');do that
:blk1.v_item_name1 := 0;doesn't?

Using Global variable in Record Group

Hi,
I have a requirement where in I need to pull a column name from a table and then use that value in the select statement of a record group. I have tried using global variables but it is not working. Here is the record group I would like to use.
RG_DOMAIN is based on LOV_DOMAIN
SELECT :GLOBAL.DOMAIN_COLUMN_NAME, DESCRIPTION FROM
DM_T_DOMAIN_VALUES
WHERE DOMAIN_NAME := BLOCK.ATTRIBUTE;
In the Key-Listval I have a select statement in which does this :
SELECT DOMAIN_COLUMN
INTO :GLOBAL.DOMAIN_COLUMN_NAME
FROM DM_T_DOMAIN_RULES WHERE DOMAIN_NAME = :BLOCK.ATTRIBUTE;
SHOW_LOV('LOV_DOMAIN');
The problem is I am not getting the value I am just getting the Domain_column name. For example for Domain_name 'CALC_TYP' the Domain_column is COLUMN_10 and I just see COLUMN_10 my LOV when I want to see the value of COLUMN_10 from the DM_T_DOMAIN_VALUES table.
I tried using Name_in and Copy but not working. Can anyone suggest a solution?
Thanks

Francois ,
I tried this but I am getting error saying record group does not exist. Can you tell me what should I go in Populate_group... and show_lov..maybe I am doing something wrong?
Declare
LC$Req Varchar2(512) ;
Begin
LC$Req := 'SELECT ' || :GLOBAL.DOMAIN_COLUMN_NAME || ' FROM ....' ;
Create_Group_From_Query( rg_group, LC$Req ) ;
Populate_group(RG_DOMAIN); ?? --- is this correct?
Show_Lov(LOV_DOMAIN) ; -- and is this correct?
End;

In Material Master Screen,functionally what is Requirement Group in the MRP

In Material Master Screen,functionally what is Requirement Group in the MRP Screen.Pls explain its functionality

Hi,
The safety time / actual range of coverage ensures that the planned warehouse stock covers the requirements of a defined number of days. It therefore serves as a time float and thus works alongside the safety stock, which acts as quantity float.
The system simulates bringing the requirements forward by the specified number of days and the planning for the receipts, created for these requirements in the planning run, is also brought forward by this number of days.
Prerequisites
·   You have set the Safety Time indicator in the material master record (MRP 2 View) to define whether the safety time is only to apply to independent requirements or to all requirements.
·    In the material master record (MRP 2 View), in the Safety Time/Actual Range of Coverage field, you have entered the number of workdays by which the requirements are to be brought forward.
·    If, in addition to this actual range of coverage, you also want to define a different number of workdays in certain periods or a safety time less than one day then, in Customizing for MRP in the activity Define Period Profile for Safety Time/Actual Range of Coverage you can define a period profile and assign it to the material in the material master record.

How to create Static Record group in Oracle Forms??

Dear All,
I have the following values V1,V2 to be placed in my list item field during DML operations.
I have an example to create the record group based on the table; whereas i have never tried for static value creation.
Could you please guide me how can i acheive this.?
Thanks ....
Regards,
Sunil.G

Thanks dhivya for your reply.
Actually what happens is; when i use the same methodology as you mentioned, it is asking me to set the Initial value.
Whereas in my applications; user has to manually select any of the values i.e eithe V1 or V2 for the first time.
Moreover i have found the query:-
I have created a static record group RG_VERSIONS i.e creating a new record group with the static values mentioning the "Column names " as "Version_label" which i have given the column values as "V1" and "V2" and then another column name as "Version_value" with the column values as "V1" and "V2".
Then i used the below query in the WHEN-NEW-FORM-INSTANCE trigger:-
PROCEDURE p_when_new_form_instance
IS
l_rg_id recordgroup;
l_item_id item;
BEGIN
--Populating value for Version Type based on static record group
l_rg_id := FIND_GROUP ('RG_VERSION');
IF NOT ID_NULL (l_rg_id)
THEN
l_item_id := FIND_ITEM ('BLOCKNAME.COLUMN_NAME');
POPULATE_LIST (l_item_id, l_rg_id);
END IF;
END p_when_new_form_instance;
Then it was working fine.
Thanks for your time.
Regards,
Sunil.G

Using 'like' in record group query

Hi ,
(Forms 6i)
I'm creating a record group dynamically.
So in when new item trigger for a list item,
i want to list all names from a table like 'a%';
query : select name, to_char(id) id from test_name where name like 'a%';
but i'm not able give single quote(') in the query.
Is there a way to do that?
Edited by: Tuts009 on May 9, 2010 1:38 AM

Hi Arif,
i'm not giving a% directly in the query, this i'm getiing from what we type in the list , so :list4
i'm storing it in another string say str and then the query will be
str := :list4||'%';
rg_id := Create_Group_From_Query( rg_name,
'SELECT name,to_char(id) id from test_name where name like '||str); Now any help?

Record Group Equivlant in ADF

Hi Gurus,
I am using jdev 11.1.2.3 and i am new in ADF. I need how we can create something like record group (Oracle Forms) in ADF.
A record group is an oracle forms data structure that has a column/row framework similar to a database table.
Actually i want to give some table interface in jsf page with checkboxes and want to perform some action on selected rows. I want send the selected rows ids to a function defined in Application Module and set the value for those ids. Here is my function
public void setPickLocationForSelectedRows(String tagNumbers, String pickLocation) {
updatePickLocationForSelectionImpl vo =
(updatePickLocationForSelectionImpl)getupdatePickLocationForSelection1();
vo.setWhereClause("TAG_NUMBER IN (" + tagNumbers + ")");
vo.executeQuery();
while (vo.hasNext()) {
vo.next();
updatePickLocationForSelectionRowImpl row = (updatePickLocationForSelectionRowImpl)vo.getCurrentRow();
row.setPickLocation(pickLocation);
getDBTransaction().commit();/*
in the tagNumbers i want to pass selected rows ids. I don't want to traverse the whole table to scan if checkbox is selected. i want check i click on checbox its value will added to some kind of array or record group and then hit button function will call and pass these values to function.
Any advice or Idea
Thanks,

That's what I call fighting the framework. Instead of trying to do it like forms, do it the adf style. Create yourself a multi select table and select t he records you want to change. Once they are selected (it works like in excel) you iterate over the selected rows and do your work.
If you really need to use checkboxes to select rows you can use http://sameh-nassar.blogspot.de/2009/12/use-checkbox-for-selecting-multiple. or http://www.gebs.ro/blog/oracle/oracle-adf-row-selection-using-checkboxes/

Using JDAPI to manipulate record group

Hi.
I am doing a migration from oracle forms 4.5 to 10g. For now I was able to manage/fix everyting using JDAPI interface. Now I am stuck with the following problem. In forms 4.5 it was perfectly legal to use a value of record group column larger than data length of that column. From forms 6+ there is a runtime error generated when this situation is met. What I wanted to do is to change/truncate record group value to the length of that column using JDAPI. No matter how I search I cant find proper metod to do the job. That is to change the value of record group column. Did anybody had a similar situation and was able to solve it.
Best regards.

URGENT : Record Group Problem

hello all
i have a problem regarding record group.
i want to populate my record group with a dynamic clause which is
"and main_code not in ('02725','02868')"
and my record group query is
"select mt.main_number from main_table mt,main_parent mp
where mt.main_code = mp.main_code
and mt.main_code not in (:parameter.param_main_code)"
now i am adopting the following method for populating the
LOV(list of values) which is attached to a text item:
assigning values i.e. '02725','02868' to my parameter object i.e. :parameter.param_main_code but the record group is not giving changd results according to my criteria i.e.'02725','02868'...
does any body knows the solution for this problem..kindly help him with it..logically the record group query should work and return a changed results for the LOV..
please help me with this.....
thank you.

I thing you can't able to do what you are trying to do, but you can achive this by using dynamic record group.
Create the dynamic record as same struncture of design time then populate it by the coding.
Sample Code is
declare
     l_rec_name RecordGroup;
     l_rec_col GroupColumn;
     l_rec_col1 GroupColumn;
     cursor l_ename is select ename from emp;
     l_row number(12):= 1;
begin
     l_rec_name := create_group('rg_dynamic',Form_scope, 100);
     l_rec_col := add_group_column(l_rec_name,'ENAME',char_column,30);
     l_rec_col1 := add_group_column(l_rec_name,'EMPNO',number_column,6);
     for i in l_ename
     loop
          add_group_row(l_rec_name, end_of_group);
set_group_char_cell(l_rec_col,l_row, i.ename);
set_group_number_cell(l_rec_col1,l_row, l_row);
l_row := l_row+1;
     end loop;
     :parameter.num_rows := l_row -1;
     set_lov_property('LOV5',group_name,'RG_DYNAMIC');
end;
I hope this will help you to solve this problem.

URGENT,FRM-41337: Cannot populat the list from record group

Hi all:
Can anyone help me in that problem?
I have a database item in the block as a list item with combo box style and I use this code in WHEN-NEW-RECORD-INSTANCE at the form module level to populate that combo box list:
DECLARE
     group_id RECORDGROUP := FIND_GROUP('group');
     list_id ITEM := FIND_ITEM('employees.job_id');
     x number;
BEGIN
IF NOT ID_NULL (group_id) THEN
          DELETE_GROUP (group_id);
     END IF;
          group_id := CREATE_GROUP_FROM_QUERY ('group','select name,TO_CHAR(id) job from cmn_jobs where job_type_id = 4720 ');
     x := POPULATE_GROUP (group_id);
     POPULATE_LIST (list_id, group_id);
     EXCEPTION
WHEN NO_DATA_FOUND THEN
null;
     END;
That code worked very well and without any problem, but when I change the list item from combo box style to poplist style then the forms give that error:
FRM-41337: Cannot populat the list from record group
And an additional null/blanke element appears in the poplist with original element that come from RECORDGROUP.
So can anyone help me to solve that problem please?

First, how I can assign a default or initial value DYNAMICALLY to my poplist.Set the default-value to a parameter like :PARAMETER.MYPARAMETER then you can assign the desired default-value to the parameter.
second, if I have popliste say X for example depend on another poplist say Y ,so when I put the code to populate popliste X on WHEN-LIST-CHANGED on popliste Y and make query then the >forms return FRM-40301 Query caused no records to be retrieved ,but when I have a copy for that code in WHEN-LIST-CHANGED and put it in WHEN-NEW-FORM-INSTANCE at the form >module the form work and returns records, so is it any error or exception in what I did.Can't answer that, you should check :SYSTEM.LAST_QUERY to see why the query does not returnany records.
At the last, which better to put the code for popliste in PRE-FORM trigger at the form module or in WHEN-NEW-FORM-INSTANCE at the form module.I would use the PRE-FORM-trigger

Hierarchical Tree Data Query/Record Group Question

I need help with Hierarchical Forms right now. I'm currently trying to implement a hierarchical tree to display the different items in different categories. I have been reading up on it for the past few days, and i do not understand a few things.
What is the difference between a data query and record group? they seem the same to me.
How does the XX = prior XXX work? i understand that this is what connects the parent to the child.
How do you determine what depth the node is? its done in the record group/data query, but how do i decide what level it is dynamically?
Thanks a lot in advance!

Thanks! I am unable to create a table specifically for the tree because i am using tables that have been ported live and are in use. My question about levels is how do I know which depth the node is. For example, i have a category called Information Technology and a category item called Business Informatics. I want to know how to decide that the Category(information technology) is on level 1 and the Item(business informatics) is on level 2.
Information Technology
|_
Business Informatics
And i do know how the Connect By XX = prior XXX works in the data query/record group.
Thanks for your help!
