Record groups
Created a record group programmtically. I am now trying to use the DELETE_GROUP_ROW. I have in debug to check that the correct
row number that I select is being picked up. When I do the delete row, I then do the show_lov. My row has not been deleted. The first
time I run my form, my query works. Thereafter selecting from the LOV does not work, problem with the delete_group_row..
Is there something I need to do before invoking show_lov. Please help.
KP
I am having the same problem. I need to update a value in the record group and I need to delete rows and I show that I am able to update the values and I see it via a debug statement, but when I show the LOV, it shows not updated.
Did you find a solution?
Similarily I need to delete.

HOW TO create a temp table or a record group at run time
i have a a tabular form and i dont want to allow the user entering duplicate
records while he is in insert mode and the inserted records are new and not exsisting in the database.
so i want to know how to create a temp table or a record group at run time to hold the inserted valuse and compare if they are exsiting in previous rows or no.
please help!As was stated above, there are better ways to do it. But if you still wish to create a temporary block to hold the inserted records, then you can do this:
Create a non-database block with items that have the same data types as the database table. When the user creates a new record, insert the record in the non-database block. Then, before the commit, compare the records in the non-database block with those in the database block, one at a time, item by item. If the record is not a duplicate, copy the record to the database block. Commit the records, and delete the records in the non-database block. -
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

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 ?

Strange Problem in dynamically list population with record group
Hello Room,
I am dynamically populating a single list with 2 record groups. I am having a strange problem. All the code are written in 2 seperate buttons. The code of every button is given below.
Button 1 code:-
DECLARE
rg_reports RECORDGROUP;
rg_name VARCHAR2(40) := 'REPORTS';
vTemp NUMBER;
BEGIN
-- Pls make sure Group doesn't already exist
rg_reports := FIND_GROUP(rg_name);
-- If it doesn't exist then create it and add ur query to it
IF Id_Null (rg_reports) THEN
rg_reports:=CREATE_GROUP_FROM_QUERY(rg_name , 'SELECT companyname,to_char(co) from companymaster order by companyname');
end if;
--Populate the Record Group
vTemp:=POPULATE_GROUP(rg_reports);
POPULATE_LIST('REPORTS.EXAMPLELIST', rg_name);
Delete_Group( rg_reports );
END;
Button 2 Code:-
DECLARE
rg_reports RECORDGROUP;
rg_name VARCHAR2(40) := 'REPORTS';
vTemp NUMBER;
BEGIN
-- Pls make sure Group doesn't already exist
rg_reports := FIND_GROUP(rg_name);
-- If it doesn't exist then create it and add ur query to it
IF Id_Null (rg_reports) THEN
rg_reports:=CREATE_GROUP_FROM_QUERY(rg_name , 'SELECT accountname,to_char(co) from accountmaster order by accountname');
end if;
--Populate the Record Group
vTemp:=POPULATE_GROUP(rg_reports);
POPULATE_LIST('REPORTS.EXAMPLELIST', rg_name);
Delete_Group( rg_reports );
END;
The code is same here only the sql is different in these 2 buttons. Now the problem point.
when i press button 1, I get the list populated ok. when i try to click on the list item and keep the button pressed the list gets scrolled properly.
when i press button 2 after that i get account names well populated in the same list item as well, but this time, when i keep the button pressed the list does not scroll below as in button 1. It does not even allow to select different item from the list of button 2 code.
I tried to clear cache, cookies, exit browser everything and try to run the button 2 first, but still the problem in button 2 code.
Following are my system details.
windows 7 professional edition.
Oracle database 11g on windows 7
Oracle forms 10g patchset 10.1.2.0.2 on windows 7
Browser Netscape Navigator with oracle jinitiator 1.3.1.22
But this form is run by a client side html file where oracle forms 10g is not installed on windows xp. html file is just referring server url to run the module. The file is run on Netscape navigator browser with oracle jinitiator 1.3.1.22
My question is that is this a bug ? if button 1 gets the list item scrolled, why is the problem with button 2 even though i press it first. Here I am deleting the record group also. after the code is over. Initially I thought this may be the character length problem so I took the maximum character length for that list item as given by the 2 columns in database.
Why is the list scrolling not happening in button 2 but in button 1 with same codes on both ?
Anybody please help me.The problem is the second query. I would guess that the TO_CHAR(co) is not unique for each account, but is the same for the accounts. And as the second item in the select-list is the listitems values, all your listitem-entries have the same value. therefore, of you select any entry, the list will always go the the first entry again.
Adjust your query. -

Creation of Record Group and LOV at run time
Hello All,
I have been stuck by this...I have two text items on which LOVs have been placed.Selection of one depends on selection of other.I can dynamically create a record group but how to create a LOV dynamically to populate it with the dynamic record group been created.
For more visualization consider that filtering of data takes place in one lOV based on the other LOV been provided.
Revert ASAP...
Thanks and Regards,
Kapil UppalI don't think you can create a LOV dynamically, but you can repopulate a pre-existing one, which should allow you to achieve the same goal.

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.

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:)
Grzegorzhi 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,

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.

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?
ThanksFrancois ,
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?

Can't use function in creating record group
Gurus,
This question is for developers. Is this true one can't use
function in creating record group. I am using form5.
thanks,
ZWI figured out the issue... they changed the way Group Calls are limited.
Here's a full explaination - and a suggestion for a behavior fix: http://community.skype.com/t5/Windows-desktop-client/Please-Fix-Group-Video-Voice-Calling-Limit-Beha...
Long story short, you can't do a video calling at all if the group has more than 10 people in it total (including you).
Also, you can't do voice calling in groups with more than 25 people.
Text chats are limited to 300 people (or so I've been told by Skype employees). I've been in a chat with over 100 participants though so I know it goes that high at least. -
Record Group In Insert Statement
Hi All,
I am using Oracle 9i Ver 2 & Developer 6i on Windows platform. I want to ask, can we pass a Form's Record Group object to a select statement as a whole. I mean something like this,
Suppose emp_rg is a Forms RecordGroup which has all the columns of scott.emp table & it contains 10 rows. So, can I write like this:
INSERT INTO emp VALUES(emp_rg);
Or anything like this, if this is wrong.
Or, I need to create a PL/SQL record object & then I can pass. Pls clarify.
Thanks in Advance,
Inderjeet SinghYes I often have trouble deciding whether to use a record group or a pl/sql table. They both have their own advantages in different situations. Manipulating record groups programatically requires rather more cumbersome syntax, but they do come with some handy built-ins (such as populate_group), and they also integrate with LOVs, Trees etc.
If you want the pl/sql table to be available throughout the form you will need to declare it in a package spec.
Even with a pl/sql table, you will need to write code to feed it into your insert statement. I reckon a global temporary table might allow the most straightforward syntax. -
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.GThanks 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.
