Three master detail on the same page

Hi
I generate master-detail pages (master and detail in the same page) and it works very well, but I can't generate three master detail (master-detail and the detail with other detail, three levels of tables) on the same page. How can I do it?
Thanks in advance

Liceth,
You cannot generate this. You can add the third level post-generation using drag and drop.

Master Detail on the same page PHP - MySQL

Hi,
Is it possible to create a page using spry master region and call MySQL data into a Spry detail region, like you do with xml data?
Basically, is there a way to have master detail regions on the same page without using frames?
Thanks
Bert

Thanks for that, very useful indeed.
But isn't it going to be slow, first transferring the MySQL data to XML then reading XML to display the records.
What is the advantage other then displaying master detail on the same page?
Thanks
Bert

Hi,
You do not need to mount a screen. Just add a new region with several text fields inside. You should fetch a row by a process and populate the set when you load the page or click on a button. Insert, update, and delete should be done by processes. You have to have Next and Previous buttons to brows trough all rows of the detail table.
The most important thing here is what the connections between tables in your database are.
If they are the "One to many, One to one" you can use the approach described above.
If they are "One to many, One to many" will be better to use buttons or links to lunch details' tables in separate forms.
If the second and third tables are connected only to the master table you can use two buttons at the right of every master row. Clicking on the buttons will bring separate form for each detail table.
If the third table is just a luckup table to the second one you can use "Select List" field into tabular form of the second table in one Master-Detail form.

Multiple (updatable) details in the same page.

Hello,
I tried to put two updatable details in the same page and got the error
"Updatable SQL Query already exists on page 11. You can only add one updatable SQL query per page. Select a different page"
So having more than one updatable detail is not allowed in apex ?
I have a master table with three details. Should I create one page for each one of them ?
Thanks in advance

What you want to use are called collections. Here is a simple collection example:
The process goes in 4 steps: gather the data, display the data, update based on user input, then write the changes. Each step requires it's own piece of code, but you can extend this out as far as you want. I have a complex form that has no less than a master table and 4 children I write to based on user input, so this can get as complex as you need. Let me know if anything doesn't make sense.
First, create the basic dataset you are going to work with. This usually includes existing data + empty rows for input. Create a Procedure that fires BEFORE HEADER or AFTER HEADER but definitely BEFORE the first region.
DECLARE
v_id     NUMBER;
var1     NUMBER;
var2     NUMBER;
var3     VARCHAR2(10);
var4     VARCHAR2(8);
cursor c_prepop is
select KEY, col1, col2, col3, to_char(col4,'MMDDYYYY')
    from table1
    where ...;
i         NUMBER;
cntr      NUMBER := 5; --sets the number of blank rows
BEGIN
OPEN c_prepop;
    LOOP
      FETCH c_prepop into v_id, var1, var2, var3, var4;
      EXIT WHEN c_prepop%NOTFOUND;
        APEX_COLLECTION.ADD_MEMBER(
        p_collection_name => 'MY_COLLECTION',
        p_c001 => v_id, --Primary Key
        p_c002 => var1, --Number placeholder
        p_c003 => var2, --Number placeholder
        p_c004 => var3, --text placeholder
        p_c005 => var4 --Date placeholder
    END LOOP;
CLOSE c_prepop;
for i in 1..cntr loop
    APEX_COLLECTION.ADD_MEMBER(
        p_collection_name => 'MY_COLLECTION',
        p_c001 => 0, --designates this as a new record
        p_c002 => 0, --Number placeholder
        p_c003 => 0, --Number placeholder
        p_c004 => NULL, --text placeholder
        p_c005 => to_char(SYSDATE,'MMDDYYYY') --Date placeholder
end loop;
END;Now I have a collection populated with rows I can use. In this example I have 2 NUMBERS, a TEXT value, and a DATE value stored as text. Collections can't store DATE datatypes, so you have to cast it to text and play with it that way. The reason is because the user is going to see and manipulate text - not a DATE datatype. If you are using this as part of a master/detail form, make sure that your SQL to grab the detail is limited to just the related data.
Now build the form/report region so your users can see/manipulate the data. Here is a sample query:
SELECT rownum, apex_item.hidden(1, c001), --Key ID
     apex_item.text(2, c002, 8, 8) VALUE1,
     apex_item.text(3, c003, 3, 3) VALUE2,
     apex_item.text(4, c004, 8, 8) VALUE3,
     apex_item.date_popup(5, null,c005,'MMDDYYYY',10,10) MY_DATE
FROM APEX_COLLECTIONS
WHERE COLLECTION_NAME = 'MY_COLLECTION'This will be a report just like an SQL report - you're just pulling the data from the collection. You can still apply the nice formatting, naming, sorting, etc. of a standard report. In the report the user will have 3 "text" values and one Date with Date Picker. You can change the format, just make sure to change it in all four procedures.
What is critical to note here are the numbers that come right before the column names. These numbers become identifiers in the array used to capture the data. What APEX does is creates an array of up to 50 items it designates as F01-F50. The F is static, but the number following it corresponds to the number in your report declaration above, ie, F01 will contain the primary key value, F02 will contain the first numeric value, etc. While not strictly necessary, it is good practice to assign these values so you don't have to guess.
One more note: I try to align the c00x values from the columns in the collection with the F0X values in the array to keep myself straight, but they are separate values that do NOT have to match. If you have an application you think might get expanded on, you can leave gaps wherever you want. Keep in mind, however, that you only have 50 array columns to use for data input. That's the limit of the F0X array even though a collection may have up to 1000 values.
Now you need a way to capture user input. I like to create this as a BEFORE COMPUTATIONS/VALIDATIONS procedure that way the user can see what they changed (even if it is wrong). Use the Validations to catch mistakes.
declare
j pls_integer := 0;
begin
for j1 in (
select seq_id from apex_collections
where collection_name = 'MY_COLLECTION'
order by seq_id) loop
j := j+1;
--VAL1 (number)
apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
      p_seq=> j1.seq_id,p_attr_number =>2,p_attr_value=>wwv_flow.g_f02(j));
--VAL2 (number)
apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
      p_seq=> j1.seq_id,p_attr_number =>3,p_attr_value=>wwv_flow.g_f03(j));
--VAL3 (text)
apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
      p_seq=> j1.seq_id,p_attr_number =>4,p_attr_value=>wwv_flow.g_f04(j));
--VAL4 (Date)
apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
      p_seq=> j1.seq_id,p_attr_number =>5,p_attr_value=>wwv_flow.g_f05(j));
end loop;
end;Clear as mud? Walk through it slowly. The syntax tells APEX which Collection (p_collection_name), then which row (p_seq), then which column/attribute (p_attr_number) to update with which value (wwv_flow.g_f0X(j)). The attribute number is the column number from the collection without the "c" in front (ie c004 in the collection = attribute 4).
The last one is your procedure to write the changes to the Database. This one should be a procedure that fires AFTER COMPUTATIONS AND VALIDATIONS. It uses that hidden KEY value to determine whether the row exists and needs to be updated, or new and needs to be inserted.
declare
begin
--Get records from Collection
for y in (select TO_NUMBER(c001) x_key, TO_NUMBER(c002) x_1,
             TO_NUMBER(c003) x_2,
             c004 x_3,
             TO_DATE(c005,'MMDDYYYY') x_dt
           FROM APEX_COLLECTIONS
           WHERE COLLECTION_NAME = 'MY_COLLECTION') loop
    if y.x_key = 0 then --New record
        insert into MY_TABLE (KEY_ID, COL1,
            COL2, COL3, COL4, COL5)
          values (SEQ_MY_TABLE.nextval, y.x_1,
              y.x_2, y.x_3, y.x_4, y.x_dt);
    elsif y.x_key > 0 then --Existing record
        update MY_TABLE set COL1=y.x_1, COL2=y.x_2,
             COL3=y.x_3, COL4=y.x_4, COL5=y.x_dt
         where KEY_ID = y.x_key;
    else
      --THROW ERROR CONDITION
    end if;
end loop;
end;Now I usually include something to distinguish the empty new rows from the full new rows, but for simplicity I'm not including it here.
Anyway, this works very well and allows me complete control over what I display on the screen and where all the data goes. I suggest using the APEX forms where you can, but for complex situations, this works nicely. Let me know if you need further clarifications.

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?

Populating a master detail on the same form

Hi everyone,
Here is my use case using the HR as an exemple. I need to create a form where I can create an new department (master) and a number of employees for that department (detail) on the same page. On my model I have a Employee view and Department view linked with a foreign key. I created a transient in the department view called nbempl (number of employee). nbempl is linked to a selectitem list where the user can select a number of employee to create for that department. I'm using PPR to display a number of detail rows for the user to fill in.
My question is how do I create x number of detail rows when the user select a number from the drop-down list? do I need a valueChangeListener on nbempl and create the rows there? could someone point me to examples similar to this.
Thank you

Thanks for your reply.
I looked at the example but my use case is different. I need to populate both the master and detail tables with new records using one form, that is one new record for dept. and any number of detail records as selected by the user. Here is the form i'm working on:
<h:form>
<af:panelForm>
<af:inputText value="#{bindings.DepartmentId.inputValue}"
label="Dept ID:"
required="#{bindings.DepartmentId.mandatory}">
<f:convertNumber groupingUsed="false"
pattern="#{bindings.DepartmentId.format}"/>
</af:inputText>
<af:inputText value="#{bindings.DepartmentName.inputValue}"
label="Dept Name"
required="#{bindings.DepartmentName.mandatory}">
<af:validator binding="#{bindings.DepartmentName.validator}"/>
</af:inputText>
</af:panelForm>
<af:selectOneChoice value="#{bindings.DepartmentsView1NbEmpl.inputValue}"
label="How many employee do you want to add for this dept.:"
autoSubmit="true" id="nbempl" immediate="true">
<f:selectItems value="#{bindings.DepartmentsView1NbEmpl.items}"/>
</af:selectOneChoice>
<af:panelGroup partialTriggers="nbempl">
<af:panelGroup rendered="#{bindings.DepartmentsView1NbEmpl.inputValue > 0}">
<af:outputText value="#{bindings.EmplTable.inputValue}"/>
<af:forEach begin="1" end="#{bindings.DepartmentsView1NbEmpl.inputValue}" varStatus="stat">
<af:panelForm>
<af:inputText label="Employee ID:" value=""/> <----------------------------- What do I put here ??
<af:inputText label="Employee Last Name:" value=""/> <----------------------------- What do I put here ??
</af:panelForm>
</af:forEach>
</af:panelGroup>
</af:panelGroup>
</h:form>
The selectOnChoice let the user select a number of detail records to add and the PPR will refresh the form and display a number of input fields in a forEach loop for employee details. Do I need to add a valueChangeListener to the selectOneChoice and insert new rows using a custom method? Is there a better way to do this? what kind of binding do I need in the page def?
Thank you.

Master and detail in the same page

db11xe , apex 4.0 , firefox 24 ,
hi all ,
i am trying to insert the master and detail data in one step in the same page :
i have two tables (clients) and (tests_administered)
the client table's region contains theses items
client_id
client_name
the other table's region contains these columns -- the tabular region
row selector
test_admin_id -- pk, hidden
client_id -- hidden , this is the one i should populate with values
and more columns
i've done this :
1- removed the condition of the tabular region .
2- Added the request CREATE to the list in condition of the APPLYMRU process -- or :request like ('CREATE')
3- Added new process with following code : -- with sequence before the applymru process and after process row of clients process
for i in 1..apex_application.g_f02.count
loop
apex_application.g_f02(i) := :p2_client_id ;
end loop ;
but nothing happened . why ? what did i miss ?
thanks

Hi,
Create a Master Detail Form through the APEX Wizard
Make sure you choose the Primary Keys for the Master Detail as one of your Column and not the ROW ID.
Selecting an existing Sequence for the Primary Key is preferred.
Select the option the where your Master and Detail appears in the same page.
Initially when you run the page your master and detail will not appear at the same time in the page when your Master Detail Form is in the entry form mode. For this you have to go to your Tabular Form(Detail Form) region, and below you will have to remove the Condition for the display of your Tabular form and set it to “No Condition”.
Now when you run the page both the Master and Detail form will appear together in the create mode but you will not be able to insert or create both master and detail records at the same time when u click the create button. For this the following needs to be done: You need to create a PL SQL Tabular Form process :
Let's say your master form is based on DEPT and your detail tabular form is based on EMP. Make sure the following things are configured:
The DEPT insert/update DML process runs before the new tabular form PLSQL process. (ie) the new PL SQL Tabular Form Process that you create should be inbetween Automatic Row Processing(DML) and Multi Row Update Process , so create the new Tabular Form Pl SQL process with a sequence number inbetween these two Processes.
Make sure you choose Tabular form while creating this PL SQL process.
The new tabular form PL/SQL process executes the following as the source
:DEPTNO := :P1_DEPTNO;
Where DEPTNO is the Foreign Key column in the Tabular Form that links the Primary Key Item P1_DEPTNO of the Master Form.
Finally this new PL SQL process conditionally runs when DEPTNO is null, so you need to add the following condition to the process:
The final step to accomplish in creating both the Master and Detail records at the same time is to make a change in the condition of the Multi Row Update Process. :request in ('SAVE','CREATE') or :request like 'GET_NEXT%' or :request like 'GET_PREV%'
-We make this change so that records get inserted into the Detail table when we click the ‘’Create” button.
Now you can Run your page and create both the Master and Detail records at the same time.
Thanks and Regards,
Madonna

Keeping heading and detail on the same page

Hi, I have a report with a group header section and a detail section. How can I keep the heading section and all the detail section on the same page without starting each group on a new page?
The detail section will have either 2 or 3 records with some of the objects set to grow if the data doesn't fit on one line. This results in several changes of group appearing on the same page which is what I want. However, what I don't want is the header section on one page with the detail section on the next, or the header and some of the detail records on one page with the rest of the detail records on the next. What I would like is the report to start a new page if the header and all the detail records don't fit on the same page but without starting a new page for every group change. How can I achieve this?

you can put the group header and details into a sub report on the old group header section.
then hide the details section

Master/Detail report on same page.

Hi, I am trying to put together a report (10g HTML DB) and can't seem to put together a master/detail report.
I would like to have a header, something like
Project Title -- Project Status etc... for each project. Then below this section
Project Detail 1
Project Detail 2
Project Detail 3
Loop through the projects
It's just two tables. projects and details. Details has a fk project.id.
I tried to do a Form -> Master Detail but it puts them on seperate pages and also allows the data to be edited. I don't need that, this is simply for display.
This is something I can put together just creating an html table in an anonymous PLSQL block but if ability is there in HTML DB I should probably try it that way.

Hi,
This can be achieved by doing something like the following:
Have a single SQL statement that joins the two tables together. eg,
select p.project_title,
d.project_detail1,
d.project_detail2,
etc
from projects p
inner join details d on d.project_id = p.project_id
This will provide a flat table with the project title in the first column for all records.
Then, in the Report Attributes, you need to switch on Column Breaks:
In the Break Formatting section, set Breaks to "First Column"
In the When displaying a break column use this format, enter #project_title#
In the Identify how you would like your breaks to be displayed, select "Repeat headings on break"
Finally, clear the "Show" tick for the project_title column
There's probably something you could do to improve formatting etc, but this should give you a start.
Regards
Andy

How can I keep the field in the same page

How can I keep the field in master frame in the same page of the detail frame?
They are in the different pages sometimes?
Thank you.

I believe the OP has a question similar to mine...
I have several groups, and the master for each group is only one line, and the detail is between 1 and five lines, like so:
A
A1
A2
B
B1
C
C1
C2
C3
...The problem is, sometimes only the master record gets printed at the bottom of the page, and then the detail is printed at the top of the next page. I don't need each group on it's own page. I just want to be sure that if the detail can't fit on the page with the master, then I want the master to only print on the next page.
Can you help with this?

BC4J - Inserting Master/Detail records in same transaction.

I know this is possible, but I seem to be missing something to allow it to happen within BC4J.
I'm creating a RowSet off of a View Object and inserting new Rows into this RowSet. This RowSet represents my child/detail records for insert into a child table.
I then create a new Row off of another View Object. This row represents my Master/parent record for insert into a parent table.
All of the above is being done in the same applicationModule transaction with locking mode set to Optimistic.
Before I commit the transaction, I grab the next sequence # to use as the primary key for the master record and the foreign key for the child records. I apply those to the newly created child rows and the newly created master row.
However, when I commit I continue to get a JBO-26041: Failed to post data to database during "Insert": error due to ORA-02291: integrity constraint (CUST_LICENSES_FK4) violated - parent key not found
If everything was created in the same transaction, why won't this allow me to insert into both tables with the correct primary/foreign keys? It's almost as if the child records are being inserted first prior to the parent record.
Any ideas?
Thanks in advance..

However, when I commit I continue to get a JBO-26041: Failed to post data to database during "Insert": error due to ORA-02291: integrity constraint (CUST_LICENSES_FK4) violated - parent key not found
If everything was created in the same transaction, why won't this allow me to insert into both tables with the correct primary/foreign keys? It's almost as if the child records are being inserted first prior to the parent record.This is due to the order of rows being posted. In this case it seems the detail row is getting posted before the master.
To avoid such situations, either you may implement your own post ordering by making sure that when a detail is to
be inserted, it's master is inserted or you may use "Composition Association" flag in the association wizard between
the master and the detail entities to let the framework manage a tight composition relationship between the two entity
types. BTW, there was another definitive thread recently on inserting master-detail in the
same transaction, but the forum search engine is so useless I can't find it. Anyone
have the msgid handy or know how to find that thread again??
FYI: the help describes the Composition flag functionality in terms of the Master record already existing in the DB. In our problem here, the Master is being inserted in the same transaction. Thus needs to be posted FIRST.
I got a integrity constraint exception too, then set the composition flag and now I get:

Master Detail Reports on the same page

hi experts. i need your assistance in one issue...
i have a master detail reports in one page. Master report displays all the products and details report shows their orders...
what i want is, when user clicks on products graph its detail graph show the orders of that particular record on the same page. Both reports would remain visible on the same page side by side.
if anyone can help?

Hi Asif48,
Just as Visakh suggest, we can add the master data and subreport in the same tablix, then set the visbility of subreport to toggle based on click action of master level row. And add some parameters to filter the related data based on the master report field.
For more details, please refer to the following steps:
Create another report as the subreport and insert some fields.
Create a parameter named Order in the subreport.
In the main report, right-click to insert a subreport in the column right of the master tablix.
Right-click the subpeort to open the Subreport Properties, and select the subreport name in the drop-down list.
In the left panel of the Subreport Properties dialog box, click Visibility.
Select Hide option, and select Product (master level row) to display the subreport to be toggled by the Product report item.
In the left panel of the Subreport Properties dialog box, click Parameters.
Select Order in the drop-down list of Name, and select [Product] (use the related filed name) in the drop-down list of Value.
If there are any other questions, please feel free to let me know.
Thanks,

Multi-row editable Detail Component on the same Page as Master (WSG)

Hello. There was a trick to place editable (with Update button and Delete? checkboxes) Detail Component on the same Page as Master. Something about a Creation of Detail Component in Property Palette Mode (against of Dialog). Can anyone point me please to those hint?
great thanks,

Look at the page branches. There will be one or more which goes to the first page. Change it to go to the current page instead of the first page.

Unable to open the detail report in the same page/window
