Join 2 tables and display in Master Detail Form

Hello Everyone,
Please help me out on the following.
I have 2 tables with common field ID I want to join the 2 tables and will show the results on Master Detail form .Please suggest me on this thing .
Thanks

Hi,
The ID primary key on the details table should be ok provided you have some means of populating it - usually via a trigger that gets a new sequence number.
When the page is loaded, do you see data in the details tabular form? Or is the problem only for when you are creating entirely new master/detail records?
When adding a new record into the details form, the FK field should be populated with the PK of the master form by default. On this report, go to the Contract_Number column and have a look at the Column Attributes for it. You should see a section for Tabular Form Element and in there are two settings - Default Type and Default. The Default Type should be Item.... and the Default should be the master record's PK page item name (eg, P1_CONTRACT_NUMBER). Underneath these settings should be the settings Referrence.... - check that these correctly point to the field on the details table. If you have different settings, try changing them - otherwise, list them here so that we can check

Master detail form ... EXTREMELY URGENT

gurus,
here is my situation -
i have 2 tables ...
master ---> base_rate_type
detail ---> base_rates
the detail table has base rates for the base rate type in master. the detail can have multiple records but, only one active base rate.
when the form is run, the user needs to see only the active base rate and on a click of a button the user needs to see the history of all the base rates (all inactive ones and one active).
this is what i'm doing --
1. created a view (base_rates_v) of all the active base rates from the detail table.
2. created a master detail form -
master ---> base_rate_type
detail ---> base_rate_v
the form shows only active records.
3. created a custom button in the detail. the custom button displays all the records from base_rates table for that master.
4. HERE IS THE PROBLEM -
user can enter future base rates (active in future), but the user cannot enter another base rate which would be active rightaway, which means there will be only one base rate ACTIVE at any point of time.
how would i validate the new base rate against the current ACTIVE BASE RATE ... ?
i think i could do it in INSTEAD-OF TRIGGER but, then how would i convey the error message back to the user as a ALERT .... ?
is it possible to alert the user from PL/SQL section of the Portal button ... ?
any ideas anyone ...
thanx a lot ...

dmitry,
here is what i'm looking for -
a base rate type can have multiple base rates, each having a start date and a stop date. at any point of time only one of them would be active.
for example -
Base rate type --> Type A
Base Rate Start Date Stop Date
7.5 10-jan-2001 10-feb-2001
7 11-feb-2001 10-mar-2001
8 11-mar-2001 9-jun-2001
7 10-jun-2001 10-jul-2001
5 10-oct-2001 10-nov-2001
so in above case the second last one is active.
the requirement is when i run the form it should show only active and future base rates. the last one in the above example is future base rate.
so, i created a view on detail table that shows only active and future base rates. and then a master detail form (the view being the detail). i also created a custom button in the detail section, that would open a report and show all the base rates for a particular base rate type ('A' in above case).
the VALIDATION that is required in the form is as follows -
the form displays following -
Base rate type --> Type A
Base Rate Start Date Stop Date
7 10-jun-2001 10-jul-2001
5 10-oct-2001 10-nov-2001
if the user enters a new base rate as foll -
Base Rate Start Date Stop Date
8 15-jun-2001 15-jul-2001
then the new base rate overlaps with the existing active base rate. if it so happens i need to ALERT the user that a active base rate already exists for that period.
how would i achieve this ... ?
it does not matter if i validate it using JS or pl/sql.
i was thinking JS would be difficult to use considering, the validation needs to go and check the existing base rates in the table.
any ideas ...?
thanx a lot ...

Null item (pk) in master detail form

Hello
I use two tables to create a master detail form, in the master table I use a PK based on an existing trigger on the db and that same field is used in the detail table as an FK.
When I create a new master detail form I want to insert all the items I need, but after I hit create button to insert the values into the master table, the pk item keeps a null value, so I would not be able to insert nothing in the details table.
How can I resolve this?
Thanks in advance
Ownr

Have a look at the update / insert process on submit. There is a place to determine where to return the primary key. Put your primary key item there
P1_PRIMARY_KEY
and the record will stay there after creation.

Master/Details Form -- Relation Property

Is it possible to set the relation join condition property for a master/detail form programmatically. If so, what is the syntax?
Thanks,
Paul Howard
[email protected]

Use this built in
SET_RELATION_PROPERTY
(relation_name VARCHAR2,
property NUMBER,
value NUMBER);
for more detail check from the help topics. Thanks for the info but the property I want to set isn't a listed property for that built-in. I need to change the actual join statement in the relation object. This is what I'm attempting to accomplish.
I have a master-detail form with the master block containing 1 field (mfg_date)/ detail block containing order information(multiple records). This form allows me to step thru my orders by mfg_date. I need to be able to also step thru these orders by due_date if the operator chooses with a radio button. If I change the query_data_name and the the actual join statement in the relation object from the object navigator and compile and run it works fine. I can change the query_data_name programmatically but I can't find any info on changing the join statement programatically. Or is there another way to change the master block within the same form some other way?
Thanks for any pointers!

Master Detail Form with Report - Referring a column in another table

I have master detail form with a report option. The master table has a column that also references a look up table.
When the report is displayed the lookup column id is displayed. Rather I want to get the look-up value from a lookup table
and display in the report.
When I see the report region Query definition , it just has the columns to add/remove only from the master table.
Could you pls help me with this regard.
Eg :
Dept Table
dept_id
dept_name
location_id
Employee Table
employee_id
employee_name
dept_id
location
location_id_id
location_name
Master is Dept, Detail is dept and lookup table is location.

Simply add the lookup table to the FROM clause and join its PK with the FK in the master table in your query. That's basic SQL, and you definitely must get a good grasp of SQL to do more than very basic work in APEX.
For a good example, please see http://download.oracle.com/docs/cd/E10513_01/doc/appdev.310/e10498/build_app.htm#BCEBJJGB
While you're at it, read and implement the tasks outlined in the 2 Day + Application Express Developer's Guide - http://download.oracle.com/docs/cd/E10513_01/doc/appdev.310/e10498/toc.htm. After that, read the "Oracle Application Express 3.0-- Building a Functional Application" OBE in http://www.oracle.com/technology/obe/apex/obe30/apexdev30.htm - great stuff.

More than one Detail table in the Master Detail forms!

Hi,
I need to have more than one Detail table in Master Detail Forms.
I want to see the details of the rows of the first Detail table in the Second Detail table. Please guide me to do this.
Sincerely yours,
Mozhdeh

You can do one of two things
1) Depends on the nature of your data model. I was able to manage many to many
relationships using views and instead of triggers. This solution is somewhat complex but can work in certain situations.
2)Works for situations where master record exists. create a page with mulitple portlets syncronized on some related key.
create the following package to use on the md forms to place on the one page to be rendered.
-- this package will facilitate the storage and retrieval of keys used by the related forms.
create or replace package session_var
IS
session_parms portal30.wwsto_api_session;
g_domain varchar2(2000) := portal30.wwctx_api.get_user;
function get_id (id in varchar2) return number;
PROCEDURE SET_ID
(ID in VARCHAR2
,p_val in VARCHAR2
,P_URL in VARCHAR2
END SESSION_VAR;
create or replace package body session_var
IS
--pkg body
function get_id(id in varchar2) return number is
l_store_session portal30.wwsto_api_session;
l_id number;
begin
l_store_session := portal30.wwsto_api_session.load_session(
p_domain => session_var.g_domain,
p_sub_domain => 'your domain');
l_id := l_store_session.get_attribute_as_varchar2( p_name => id);
return l_id;
end get_id;
PROCEDURE SET_ID
(ID in VARCHAR2
,p_val in VARCHAR2
,P_URL in VARCHAR2
IS
l_store_session portal30.wwsto_api_session;
begin
l_store_session := portal30.wwsto_api_session.load_session(
p_domain => session_var.g_domain,
p_sub_domain => 'your domain');
l_store_session.set_attribute(
p_name => id,
p_value => p_val );
l_store_session.save_session;
* Redirect to the page using p_url;
portal30.wwv_redirect.url(P_URL);
end set_id;
END SESSION_VAR;
--the form master detail form, section before display page enter the following code and publish as portlet.
declare
l_fs varchar2(4000);
l_s varchar2(4000);
v_con_id number;
begin
v_con_id :=rfq.session_var.get_id('CON_ID'); -- primary key and key used to relate details
p_session.set_shadow_value( p_block_name => 'MASTER_BLOCK',
p_attribute_name => 'A_CON_ID', -- attribute on form related to primary key
p_value => '= '|| v_con_id,
p_language => portal30.wwctx_api.get_nls_language ,
p_index => 1
l_fs := p_session.get_value_as_varchar2(p_block_name => 'MASTER_BLOCK', p_attribute_name => '_FORM_STATE');
l_s := p_session.get_value_as_varchar2(p_block_name => 'MASTER_BLOCK', p_attribute_name => '_STATUS');
if l_fs = 'SAVE' and l_s is null then
WWV_MASTER_GENSYS_1(p_block_name => p_block_name,
p_object_name => p_object_name,
p_instance => p_instance,
p_event_type => p_event_type,
p_user_args => p_user_args,
p_session => p_session);
p_session.save_session;
end if;
if l_fs = 'QUERY_AND_SAVE' and l_s is null then
WWV_MASTER_GENSYS_1(p_block_name => p_block_name,
p_object_name => p_object_name,
p_instance => p_instance,
p_event_type => p_event_type,
p_user_args => p_user_args,
p_session => p_session);
p_session.save_session;
end if;
exception
when others then
PORTAL30.wwerr_api_error.add(PORTAL30.wwerr_api_error.DOMAIN_WWV,'app','generic','onLink', p1 => sqlerrm);
raise;
end;
--then create other md forms and publish as portlets in a similar manner.
-- create a form (form_session_vars) to call procedure session_vars and place the following code in the
addiontional pl/sql tab
WWV_GENSYS_1(
p_block_name => p_block_name ,
p_object_name => p_object_name,
p_instance => p_instance ,
p_event_type => p_event_type ,
p_user_args => p_user_args ,
p_session => p_session);
--then create a page and place the md forms created above as portlets on the page.
--create a link and target the form_session_vars and in the link target inputs
enter the values for your user parameters
id= CON_ID --"your primary key name"
p_url= url/page/"your_page"
--finally create a report (QBE or standard).
in the column formation section use the link created earlier to direct the user to the target page.
How it works.
When the link is selected the form_session_Var is called and automatically runs setting the primary key values
in the user session store. The step is required or the resulting page will not render properly. Then the user is redirected to the page where the portlets are rendered. The portlets start rendering, the before display page calls the session vars package to retrieve the key and put the form into query_update mode returning the data.
The portlets finish in query_and_save mode with details in update mode, the allowable insert, delete and none actions will be available for the details.
benefits: The session_Var package code is resuable as well as the form form_session_Var and the link. passing the key name and values are done at the report level and detailed in the report links. the md forms will need to reference their related keys.

Master Detail Form is ignoring the 4th join condition

Hello All,
I have master detail relationship between two tables with a
composite foreign key (of 4 columns). I'm creating a master
detail form in O9iAS Portal 3.0.9.8.0 on these 2 tables
successfully with no errors. The only thing I have noticed, is
that the wizard does not populate the join conditions
automatically in step#3. The form runs Okay but it ignores the
last condition (i.e., 4th), which means that it brings too many
details records.
Any ideas
Much appreciated if you can CC me: [email protected]
Hamada Hima

I had this same problem with master/detail form and 4 join conditions. I opened up a TAR and after several weeks
Oracle determined this to be a bug and submitted it to developers.
For a work around, I created a view with two of the join fields concatenated together, then created another md form
with 3 join conditions and it worked. Good luck.

How can I insert in the table detail of a master/detail form??

Hi Law,
Text in a shape or a text box will not feature in the table of contents.
To get a colour behind your titles, type them into your document (not a shape). Format as Heading or some other paragraph style the TOC will recognise.
Select the title text and Format Panel > Text > Font > Gearwheel > Advanced Options.
Choose Character Fill Color and choose a colour from the palette (left) or colour circle (right).
Example Titles (all on the same page for a smaller screen shot).
Chapter 3 (in a coloured Text Box or Shape) does not appear in the TOC:
Hint for cheats :
To give the titles a wider Character Fill Colour, add some Tab characters before and after.
Regards,
Ian.

Problem in Master Detail form when using ADF table for Detail

hi,
jdev version-11.1.2.1.0
i have create Master detail form using datacontrol drag as ADF Master Form Detail Table.
Now when i create a new row in Detail table using CreateInsert button a blank new row created on the top of detail table.
and other row show that data of previous record based on master.
problem is that i want when i click on createInsert button all row of detail table should be blank and when user fill two or three row then commit.
Thanks in Advance

Hi,
if a detail table has data, then createInsert adds to these. If you want to hide existing rows, create a new View Object instance and set its "Retrieve from the Database" option to "No Rows". The use an af:switcher to change the table shown when the user clicks the createInsert button. There is a bit of coding required to have this use case in ADF, but its mostly declarative. Bottom line is that there is no automated option other than creating new rows in a separate page or dialog if you are bothered by existing rows

Controlling display of details in Master Detail form

Hi
I have a Master Detail form that opens up only in update mode. The master record is display only and only one of the detail fields, "Qty Fulfilled" is editable and the rest are display only. So, the form currently, has a text box only for the Qty fulfilled field.
I set the # of detail rows option to 5. So my form shows a column of 5 boxes, even if there are only 2 detail row.
How do I hide the remaining 3 boxes which have no data in them?
Please help , this is urgent.

How to display more rows in Master-detail form

I am working on APEX3.2.
I have a master-detail form. The detail form always display 15 rows. However, my customer wants the detail display all the rows. I tries to configure the Number of Rows in the report. It doesn't work. How do I do it?
Thanks a lot!

Hi:
To increase number of rows displayed you have to set Number of Rows and pay attention to both Number of Rows (Item) and Maximum Row Count.
After that if didn't work, sign out or close the browser then open it again. Sometimes it keeps the value in current session.
Saad,

Master Details form (LOV based on Detail Column of Join Condition)

I have created a master detail form where user_id is joining master and details.
I have created one dynamic lov based on child user_id in detail block to diplay all user who works under current user.
Problem : When i want to select Insert detail action in detail block the dynamic lov should read the user_id which is going to be inserted when you press Save button. Means as its not getting populated till one click on save button my lov is not getting refereshed.
Please advice what should i do.

Inconsistent inserts into detail table of master-detail form

Hello,
[I am not sure if this is a bug or user error, so I've also put this in the bug tracking system. Apologize for the 'duplication']
I have a master-detail form: Orders is the master, and Order_Details is the detail. I have noticed some inconsistent behavior when inserting the detail information.
On occasion, the row will be inserted, and a null value will get inserted into the database for the first column of the detail table; all the other data values will be inserted fine. There doesn't seem to be any pattern to when it happens. I wrote down the following test steps:
1. Enter new order information and click 'Create'
2. Click 'Add Row' button so can add order detail info
3. Enter detail row information
4. Click 'Add Row' (I do this so I can see the success message that the detail data was actually inserted)
5. Click 'Apply Changes' at the master level.
I ran a query on the order details table and saw that the data inserted correctly. Then I ran the following test:
1. Enter new order information and click 'Create'
2. Click Add Row button so can add order detail info
3. Enter detail row information
4. Click 'Add Row' (success message appears that detail was inserted)
5. Enter second detail row information
6. Click 'Add Row' (success message appears that detail was inserted, however, now in the first column of that second detail row - the product name field/column - the data does not appear. I only see my null text value. The data in the first detail row is all correct)
7. Enter third row detail information
8. Click 'Add Row' (success message appears that detail was inserted, and this row's information appears correctly, as does the first row's, but the second row is still showing a null value for the product name column)
9. Click 'Apply Changes' to get out of the form
A query of the order details table shows that a null value (-) has indeed been inserted into the table for the product name column of the second detail row.
This behavior also happens when I don't have a null value for the LOV (i.e., it defaults to the first row of the lookup table).
Has anyone seen this before? Am I entering the data incorrectly?
Thanks.
