Download link in master detail form

I am trying to store a PDF file in the DB and then allow users to click on a link to download it. However, I can't get this to work properly. The report region definition does not allow me to alter the source. What I did was create a master detail form and report. Then, I changed the format mask of the field that will be the PDF download link to BLOB and I got this error: ORA-06502: PL/SQL: numeric or value error: character to number conversion error To fix this I need to alter the source code and add the following dbms_lob.getlength("BLOB_CONTENT") as "BLOB_CONTENT". How can I do this if the report region definition is not allowing me to edit it? Is there any other way to do this?

"197331",
For Source Value, try uppercase instead: APPSDEPENDENTON

Create link in Master Detail form

Hi,
I created a master-detail form based on Dept, Emp tables. For each employee, I would like to go to the employee's dependent information (like a master -> detail -> detail situation). Can I create a link on the employee field (empno) so that I can link to my employee-dependent form?

Adding button to report to link to master detail form

I want to add a button to a report to direct me to a blank master detail form to insert a new record. I have used the following code in the additional PL/SQL code section:
htp.formopen('PORTAL30.wwa_app_module.new_instance?p_moduleid=1271601405');
htp.formsubmit('p_request','Create New');
htp.formClose;
When I click this I get 'Page Not Found'.
But if I hit refresh I am directed to the correct form with the same url.
Any ideas on what the issue is?
Thanks.

Hi,
Check this sample code.

at selection-screen.
   if sscrfields-ucomm = 'FC01'.
perform f_alv_sub.
   elseif sscrfields-ucomm = 'FC02'.
   endif.
Hope it helps.

Many to many master detail form

Hi All,
APEX 3.1.2 on SuSE 10 Oracle 10.2.0.3 64 bit
I am new to APEX, but used OAS several years ago. Back then I hardcoded all htp.print commands. We are building an intra-team application to track system relationships. For example,
web interface 3 --> application server 2 --> database 6
Our tables are similar to the following
SYSTEMS
system_id (unique sequence)
system_type_id (database, app server, apache, etc.)
SYSTEM_TO_SYSTEM
publishing_system_id - number
consuming_system_id - number
We would like to have a master detail form where we would query database 6 for example, and then see all related systems one level below it (application server 2 in the example above). I have been able to query the related systems and show them in a drop down pick list on the detail form, but I cannot edit them.
The wizard asked for the primary key of the detail table, which in this case is not a sequence generated value, but a pick from a systems table lookup on system_id/system_name.
If the master form would automagically lass the system_id to the publishing_system_id on the detail form, and allow me to update that with a picked system_id tied to consuming_system_id, that would be perfect.
I can write the htp calls I mentioned earlier, but I am sure I am missing something.
Does anyone have any best practices for this?
Thanks!
Steve

Hi Steve,
Here is an example which might help you:
http://apex.oracle.com/pls/otn/f?p=43368:35
Here, I have used two tables e.g. test1 and test2. Test1 has an id column which is just a sequence column and the name column in this table has a unique key.
Table test2 has id column as primary key and name1 column is linked with Test1 table on the Form. Name2 column is not required to be linked with Test1 table.
If this is what you are after, then I can give your more detail for it.
Hope it helps.

Master/Detail form with modal edit

I have a master/detail form that I generated using the wizard that I want to change to have a modal Edit button; i.e. the behavior I want is that the form view is initially read-only and you then have to click an Edit button to make the form editable.
I figured out how to do this for the master row by making the edit button redirect back to the same page with the request set to 'EDIT' and then making all the page items read-only with a condition REQUEST <> 'EDIT'.
I cannot find a good way to do this for the detail rows, which are actually a report with editable columns. The problem is that the 'Tabular Form Element' section of the 'Column Attributes' page does not have a read-only condition.
The only work around I can come up with so far is to have a second read-only report region with the same SQL query and then display either the editable or non-editable report region conditionally depending on whether the request is EDIT. But this obviously not ideal (having same SQL in two places, etc.).
If anyone can think of a better way to do this, I'd be grateful.
HTML DB Team: Can you log the addition of a read-only condition attribute on editable report columns as an enhancement request?

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.

Master detail form Error in mru internal routine: ORA-20001

Hi,
i created a master-detail form with apex standrad wizard.
Master e datail are on the same page.
All works fine.
My detail form contain some fields of my detail table.
Now i added a link on detail form for call a form with all fields of my detail table.
The link work fine.
When i try to add row or update my detail form i receive the error
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "D472A2BF636CA11122F196B8A32B3DC8", item checksum
Any help?
Thanks in advance
Lukx

Lukx,
I've just reproduced your what I believe you wanted and didn't receive any errors. Here are the steps I took.
1) Used the wizards to create a Master Detail form (with Detail edit on the same page as the master and only showing 2 of the detail columns)
2) Used the wizard to create a FORM ON A TABLE for my detail table allowing the user to edit all detail columns
3) Created a "column link" column on the detail form of the Master Detail form which links to the FORM ON A TABLE, passing across the ID of the detail record.
When I do this, everything seems to work perfectly as expected.
Is there something I'm missing in the steps you performed to create your scenario?
Thanks

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

HELP: Error while insert in master-detail form!!!

Hello
I have created a master-detail form and when I tried to insert a new record I got an error that the field on the detail table that references the primary key on the master table can not be null. I don't understand this error because I thought that when you create a master-detail form and you insert a new record the field that make the references in the detail table to the primary key on the master table will be automatically filled, am I wrong??. Can anybody tell me what is going on??. The primary key of my master table is filled with a trigger before insert, is that the problem??.
Please Help me is really urgent
Ana Maria

I am still new to this, but maybe this will help.
1. Double check that your foreign key link definition in the detail table is referencing the correct column in the master table. If this is not present or referencing the column, this may be causing the problem. Self evident, but sometimes it is the simple things that get us.
2. I have not used a trigger yet, but could there be validation being done in the form before the trigger is firing. Therefore, there would not be a value in the detail part of the form.
Hope this was of some help.

Creating Detail record in Master Detail form

I have created a Master Detail form with the Detail form being on a second page.
I have no problem editing an existing detail record. However, if I attempt to create a new Detail record (insert). I get an error. It appears that the value of the field that I am linking the Master and Detail records with, does not get passed to the second (detail) form when I press the 'Create' button and I have not been able to ascertain where I may need to modify the parameters of the page.
Any guidance would be appreciated.

Hi Judy,
It's been 5-6 months since I've created a Master/Detail APEX application, but I don't remember having to create any special trigger or anything. I created a few maintenance appls over tables I created, and created an inquiry appl using Oracle vendor tables. All of them have worked nicely.
If the PK/FK's are set up correctly it just works. :-) Like magic. If I recall correctly, as you create the appl you define the the key fields to use. If the tables are defined correctly, and you 'tie' them together using the correct key fields in the application everything should work nicely.

Auto Query in Master Detail Form using dynamic page doesn't work

I created a Master-Detail form, and implement AutoQuery using a dynamic page
with the following code :
<HTML>
<BODY>
<ORACLE>DECLARE
nre_ VARCHAR2(100);
BEGIN
nre_ := emp_nre;
if nre_ is not null then
net_portal.Popula_Agregados(nre_);
net_portal.Popula_Docs_Agregados (nre_);
htp.p('<iframe id=myFrame name="myFrame" frameborder=0 width="250%"
height="300"
src="/pls/portal/PORTAL.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=

388118140&p_arg_names=_show_header&p_arg_values=NO&p_arg_names=_cad_nre_cond&p_a

</iframe>');
end if;
EXCEPTION
WHEN OTHERS THEN
htp.p(SQLERRM);
END;
</ORACLE>
</BODY>
</HTML>
It works fine when we access the first time to the page, but if i press the
save button after inserting or updating a detail record, the header record is
lost. How can i avoid this situation ?

I changed query:
select
Replace(
'<img src="#IMAGE_PREFIX#ed-item.gif" border="0" alt="EditMap" usemap="#editmap***id***"></img>
<map name="editmap***id***">
<area shape="rect" coords="0,0,16,16" href="http://apex.oracle.com/pls/otn/f?p=&APP_ID.:'
|| decode ( type, 'FOLDER', '33', '22' )
|| ':&APP_SESSION.::&DEBUG.::P'
|| decode ( type, 'FOLDER', '33', '22' )
|| '_ID,P'
|| decode ( type, 'FOLDER', '33', '22' )
|| '_CALLING_PAGE:' || id || ',&APP_PAGE_ID." ></area></map>' ,
'***id***', id
) Edit,
id,
type,
name,
decode ( type, 'FOLDER', 33, 22 ) target
from tThe idea is - each img uses its own map.
It works now.

Passing values in master detail form

Hi,
I'm using Oracle Database 10g Express Edition.
Application Express 2.1.0.00.39
I've created a Master/Detail Form like this
1. create page
2. Form
3. Master Detail Form
4. selected master table
5. selected fields
6. selected detail table
7. selected fields
Master and Details entries are in different pages.
everything is ok, but i want to pass more than 1 column value from master to detail page. How can i do this?
Thanks and Regards,
Sudha.

Hi,
Values are passed from the master page to the detail page using a column link. By default, the primary key column is passed from the master page to the detail page. To pass further values, add further source columns / target items to the 'Column Link' attribute of your master report's link column.
Hope this helps,
Andrew.

Bind variable in Master Detail form

Is there any way to go to a specific master record (bind variable) and it's associated detail information in a master detail form using a link from another report?
Louis

I suspect that he may have the same question I do. Namely, if I have four tables (employees, projects, tasks, and project_assignments) how do I create a master detail form where I can specify the project and the employee via LOVs? The project_assignments table contains foreign keys for employee, project, and task, as well as additional fields relating to the task status.
Currently, I have it set up so that the employee name can be selected and the project is hard coded to the current project.
Is there an easy way to populate the detail records based on two LOVs in the master form?
Thanks in advance,
Fritz

How to create a master detail form on same page in apex 4.2.1

Hi All,
i need to design a master detail form on same page i am not finding an option in wizard from where i can do that.
will appreciate your suggestions.
Thanks

Hi James,
I think that Mike is suggesting that you create a SQL View over the table and join together the individual primary key values into a single, unique, pseudo primary key. You can still include the individual columns in the SQL but you can then use this new column as the primary key on a form. However, you would also need to create INSTEAD OF triggers to handle inserts/updates/deletes as SQL will not allow you to update tables through a view. (See: [http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28370/create_trigger.htm#i2064426] for the Oracle details on this or Re: How to update view resp. table for an example within Apex).
Ideally, though, you should only really need one key column - is there any need for four?

Master Detail Forms with 2 composite primary keys - Is there a workaround?

Hello All,
I have been searching for a workaround to the maximum 2 part primary key restriction on the multi-row updates, and master-detail forms, and am hoping that someone can help me. I am using HTMLDB v2.0.0.00.49 with IE 6 against a 9.2 DB.
I successfully implemented the workaround of Fred Stoopendaal's (see Updata PK on HTML DB ) and it works fine for single page multi-record updateable forms, but alas I haven't been able to extend it to master detail forms (I think it is something to do with Oracle not allowing the "returning" clause on views).
Here is what I tried:
two tables, one with a 2 part composite primary key, which is the master table, and a detail table with 3 part composite primary key -
--------- BEGIN SQL ---------
create table master_table
( master_col1 number
, master_col2 number
, master_col3 varchar2(30)
, constraint master_pk primary key (master_col1,master_col2));
create table detail_table
(detail_col1 number
,detail_col2 number
,detail_col3 number
,detail_col4 varchar2(30)
, constraint detail_pk primary key(detail_col1,detail_col2,detail_col3)
, constraint master_detail_fk foreign key (detail_col1,detail_col2) references master_table(master_col1,master_col2));
create or replace view v_master_table as
select rowid mata_rowid,mata.*
from master_table mata;
create or replace view v_detail_table as
select rowid deta_rowid,
(select rowid from master_table mata where mata.master_col1 = deta.detail_col1 and mata.master_col2 = deta.detail_col2) deta_mata_rowid
, deta.*
from detail_table deta;
create or replace trigger mata_ins_upd_trg
instead of insert or update on v_master_table
referencing new as new old as old
for each row
begin
if inserting then
insert into master_table (master_col1, master_col2, master_col3)
values (:new.master_col1, :new.master_col2, :new.master_col3);
end if;
if updating then
update master_table
set master_col1 = :new.master_col1,
master_col2 = :new.master_col2,
master_col3 = :new.master_col3
where rowid = :old.mata_rowid;
end if;
end;
create or replace trigger deta_ins_upd_trg
instead of insert or update on v_detail_table
referencing new as new old as old
for each row
begin
if inserting then
insert into detail_table ( detail_col1, detail_col2, detail_col3, detail_col4)
values (:new.detail_col1, :new.detail_col2, :new.detail_col3, :new.detail_col4);
end if;
if updating then
update detail_table
set detail_col1 = :new.detail_col1,
detail_col2 = :new.detail_col2,
detail_col3 = :new.detail_col3,
detail_col4 = :new.detail_col4
where rowid = :old.deta_rowid;
end if;
end;
--------- END SQL ---------
Then I created a master-detail form in Apex on the two views, using the mata_rowid and deta_rowid as primary keys, and mata_rowid=deta_mata_rowid as the link. I realise that using a function to fetch the master rowid within the detail view query is costly, but it was my intention to modify the record fetch queries to use the real FK columns once things were up and running.
It seems to generate the pages ok, and I can insert/update master table records, but as soon as I modify records in the detail table things go a bit haywire. I can't find any documentation on how the inbuilt MRU/MRD logic works, so can't figure out the issue.
Can anyone out there tell me what the problem is with the logic above, or if they have come up with a neat solution to this annoying limitation. I know that many will say that I should modify the data model to use surrogate primary keys, but many of the uses for HTMLDB are new interfaces for old schemas, so a workaround that doesn't involve wholesale data model changes would be preferable.
Thanks in advance,
Mike Cretan

Hi, this is likely not the most elegant way...but perhaps the simplest -- and I didn't have much time to play.
I used Wizard to create two separate Master Detail forms, each with a separate detail table. Thus I ended up with four pages:
Page "A" - "Selector" page for Master (Report), with Edit link driving to Detail-1
Page "B" - Editable Master/Detail-1 page (HTML / Report)
Page "C" - "Selector" page for Master (Report), with Edit link driving to Detail-2
Page "D" - Editable Master/Detail-2 page (HTML / Report)
Then I selected the primary key column TWICE on the Report on Page A. Modified the second instance of this column to navigate to Page D (passing primary key) exactly the way the original instance of this column navigates to Page B. Then I deleted Page C.
Since you can have only one Tabular Entry form per page, this seemed the best way to drive two separate detail tables from a common interface.
