Updateable columns

I have a report with updateable columns. Somehow I can not change the column display length, no matter what I change in the "Updateable Column Attributes". Is there any way to change the column length & width? Also, I can't seem to make the column values wrap inside the cell. How can I change the text to wrap and fit the cell height?
Thank you!

I have found that the most extensible way to do something like this is to manually create a reqport with updateable columns see the HOWTO on OTN on this.. basically using html_item API to load the column values from the database and draw them in the report using the field types of your choice.

Updateable Column attribute

Hi,
I am trying to create a simple report based on a SQL query, something like this,
select id, customer_id
from master_table
where status='open'
I changed the column, Customer_id's Updatable Column Attribute to "Display as Text (based on LOV, does not save state)" and chose an existing LOV. But for some reason I get the following error when I run the report,
report error:
ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error
I have used the same LOV (LOV query- select distinct name, id from customers) else where in my application (in Forms and not in any reports) and it works fine. Does anyone know what is going on here? Any help is greatly appreicated.
Thanks.

I'm running into the same issue. To make it even more unusual, the report runs fine in database1, but when I exported the application and imported into database2, I get the error in database2.

Updateable columns with primary key

Hi,
I use HTML DB 2.0 and 10g R1.
With HTML DB i would like create an application with 2 pages.
The first page is an report from a table with 2 columns, the first column is datatype number(10) with primary key and the second column is varchar2(255).
The report should looks like with an edit-icon for all rows and both columns with header.
My problem is, the report has only 2 columns, not 3 columns and the edit-icon is together with the first table column, the header name is Edit.
What can I do ?
The second page should be a form linked from the first page for update, insert and delete rows. It's not possible to use a sequence on column with pk for new inserts.
I don't know, which sample application has the same content or what I have to do.
Who can help me ?

Simply create an application "Report and Form" based on your table and modify it as follows:
- On the report page, modify the query to include the PK column a second time (using an alias)... if this was based on the EMP table with EMPNO being the PK, the query then looks like this (modification bold):
select
"EMPNO",
"EMPNO" as "EMPPLOYEE NUMBER",
"ENAME",
"JOB",
"MGR",
"HIREDATE",
"SAL",
"COMM",
"DEPTNO"
from "EMP"
where
instr(upper("ENAME"),upper(nvl(:P1_REPORT_SEARCH,"ENAME"))) > 0 or
instr(upper("JOB"),upper(nvl(:P1_REPORT_SEARCH,"JOB"))) > 0
- In the report attributes, move the added column to the desired position (I moved it directly next to the edit link).
- On the Form page, just change the item holding your PK column from "hidden" to "Text field".
You may take a look at http://htmldb.oracle.com/pls/otn/f?p=PK_VISIBLE:1 to verify this is what you're looking for.
Edit: Oops - I just recognized I cannot update the EMPNO on page 2 since the automated row processing depends on an unchanged PK. However - normally it isn't a good idea to update a PK anyway (since it might be used as FK in some other table(s)).
It is possible to create new records with manually adding the new PK, so if this is really all you need, then I would suggest you modify your edit page displaying the PK column read-only when editing an existing row and updatable when adding a new record (using 2 items with conditional display, based on the PK being NULL or NOT NULL).

How to get the column values from a BC4J View Table in UIXML?

I am using a default UiXML Application for Order Entry system with Orders & Order Lines & Customers. I have a uix file OrdersView1_View.uix which displays (no updateable columns) all the Orders. How do I get the column value of a selected row in a BC4J Table (example:OrdersId) when a Submit button is pressed using UIXML or Java Classes?
I appreciate any help on this.

Hi,
You need to use keyStamp, an example:
<bc4j table name="orders">
<bc4j:keyStamp>
<bc4j:rowKey name="key" />
</bc4j:keyStamp>
Furthermore, you can automatically send the selected row key using the go event handler, so in the handlers section you could send the key to an orderInfo page:
<event name="show">

<ctrl:go name="orderInfo" redirect="true">
<ctrl:property name="key">
<ctrl:selection name="orders" key="key" />
</ctrl:property>
</ctrl:go>
</event>

Is it possible to add columns/attributes in an Extended EO?

Hi all,
I need to add new updateable columns-attributes to an standard VO. (oportunities in sales module).
The problem is that this columns are not in the EO, so my question is how to add this columns to the Extended EO, so I can use them in an extended VO.
Any help would be appreciated, because I have not seen anything related to this in the developers guide.
Thanks in advance.

If the columns belong to the same table as in your existing EOs but not included then you can directly add them in the EO. If you are trying to derive the columns from a different table then you can join the new table and add the columns in your extended VO.

SQL Query issue with large varchar column

I have a SQL Query (PL/SQL function body returning SQL query) which contains a large varchar column. Even if I substring the column to 30chars when it displays on the page it wraps. I have tried putting nowrap="wrap" for the HTML table cell attributes and it still wraps. I have tried setting the width attributes on the column even though it's not an updateable column. Does anyone have any ideas on how prevent this from wrapping. In some cases 1 line will take up 3 because of this wrapping issue and it's not nice to look at. It seems that the column is somewhere set to a fixed width, which is less than 30 characters, and anything beyond this fixed width wraps.

Hi Netha,
Can you please provide the DDLs of three tables you are using,
Also post us how many rows you are getting output for this query?
select * from dim.store st where
st.store_code = 'MAUR'
also try to run and update statement on this table as below and execute your query
update dim.store
set store_code
= ltrim(rtrim(store_code))
where
store_code = 'MAUR'
once you run this update, then run your query. Let us know the result.

Block based on Stored Procedure - Update Changed columns only

If I were to base a block on stored procedures that includes an Update procedure but only update SOME of the updateable columns, what happens?
Does the Form send to server ONLY
1) The rows that were updated
2) The columns that updated
3) All columns in the row being updated regardless of whether they were updated
Is the correct answer 1) + 2) or 1) + 3)
Please help.
Thanks

Initialize sub sequence column values on insert?

I asked this on stack overflow, but it was recommended that I also ask here.
http://stackoverflow.com/questions/12982875/initialize-sub-sequence-column-values-on-insert-oracle
I would like my table to sequence its "order by" column based on it's TEMPLATE_ID. I would like this to happen on insert (via an insert trigger, probably). For example, if I run the following inserts, I should get the following table values.
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (1, 1)
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (2, 1)
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (3, 1)
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (4, 2)
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (5, 2)
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (6, 2)
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (7, 2)
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (8, 3)
ID TEMPLATE_ID ORDER_BY
1           1        1
2           1        2
3           1        3
4           2        1
5           2        2
6           2        3
7           2        4
8           3        1I first tried to create this trigger, but it gives me an error when I insert.
create or replace
trigger TEMPLATE_ATTRIBUTES_AF_INS_TRIG
   after insert on TEMPLATE_ATTRIBUTES
   for each row
begin
    if :NEW.ORDER_BY is null then
       update TEMPLATE_ATTRIBUTES
       set ORDER_BY = (select coalesce(MAX(ta.ORDER_BY), 0) + 1 from TEMPLATE_ATTRIBUTES ta where ta.TEMPLATE_ID = :NEW.TEMPLATE_ID)
       where ID = :NEW.ID;
    end if;
end;The error it gives me is: "table TEMPLATE_ATTRIBUTES is mutating, trigger/function may not see it"
So I need a different way to build this trigger. And I also need it to "thread safe" so that if these two inserts occur on different sessions at the same time, then the resulting records will still get different "ORDER_BY" values:
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (1, 1)
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (2, 1)
Edit:
I tried the common work around for the "table is mutating, trigger/function may not see it" and the work around "worked" but it was not "thread safe." I tried to add locking but it gave me another error on insert
create or replace package state_pkg
as
type ridArray is table of rowid index by binary_integer;
newRows ridArray;
empty   ridArray;
end;
create or replace trigger TEMPLATE_ATTRIBUTES_ORDER_BY_TB4

begin
state_pkg.newRows := state_pkg.empty;
end;
create or replace trigger TEMPLATE_ATTRIBUTES_ORDER_BY_TAF1
after insert on TEMPLATE_ATTRIBUTES for each row
begin
if :NEW.ORDER_BY is null then
    state_pkg.newRows( state_pkg.newRows.count+1 ) := :new.rowid;
end if;
end;
create or replace trigger TEMPLATE_ATTRIBUTES_ORDER_BY_TAF2
after insert on TEMPLATE_ATTRIBUTES
declare
v_request     number;
v_lockhandle varchar2(200);
begin
dbms_lock.allocate_unique('TEMPLATE_ATTRIBUTES_ORDER_BY_lock', v_lockhandle);
while v_request <> 0 loop
    v_request:= dbms_lock.request(v_lockhandle, dbms_lock.x_mode);
end loop;
begin
    for i in 1 .. state_pkg.newRows.count loop
      update TEMPLATE_ATTRIBUTES
      set ORDER_BY = (select coalesce(MAX(q.ORDER_BY), 0) + 1 from TEMPLATE_ATTRIBUTES q where q.TEMPLATE_ID = (select q2.TEMPLATE_ID from TEMPLATE_ATTRIBUTES q2 where q2.rowid = state_pkg.newRows(i)))
      where rowid = state_pkg.newRows(i);
    end loop;
    v_request:= dbms_lock.release(v_lockhandle);
EXCEPTION WHEN OTHERS THEN
    v_request:= dbms_lock.release(v_lockhandle);
    raise;
end;
end;This gives me:
ORA-04092: cannot COMMIT in a trigger ORA-06512: at "SYS.DBMS_LOCK", line 250 ORA-06512: at "TEMPLATE_ATTRIBUTES_ORDER_BY_TAF2", line 5 ORA-04088: error during execution of trigger 'TEMPLATE_ATTRIBUTES_ORDER_BY_TAF2' ORA-06512
Edit 2: The ORDER_BY column must be an updateable column. ID actually uses a sequence and before insert trigger to set its values. I thought I was simplifying my question when I included it in the insert examples, but that was incorrect. ORDER_BY's initial value is not really related to ID, but rather to what order the records are inserted. But ID is sequenced so you can use that if it helps.

Check here below:
create table TEMPLATE_ATTRIBUTES
( ID           INTEGER
, TEMPLATE_ID INTEGER
, ORDER_BY     INTEGER
CREATE OR REPLACE TRIGGER templ_attr_bf_ins_trg
   BEFORE INSERT
   ON template_attributes
   FOR EACH ROW
BEGIN
   IF :new.order_by IS NULL
   THEN
      SELECT NVL (MAX (ta.order_by), 0) + 1
        INTO :new.order_by
        FROM template_attributes ta
       WHERE ta.template_id = :new.template_id;
   END IF;
END;
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (1, 1);
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (2, 1);
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (3, 1);
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (4, 2);
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (5, 2);
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (6, 2);
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (7, 2);
INSERT INTO TEMPLATE_ATTRIBUTES (ID, TEMPLATE_ID) VALUES (8, 3);
SELECT * FROM TEMPLATE_ATTRIBUTES;
Output:
        ID TEMPLATE_ID   ORDER_BY
         1           1          1
         2           1          2
         3           1          3
         4           2          1
         5           2          2
         6           2          3
         7           2          4
         8           3          1
{code}
Let me also comment that I don't like this solution. It might conflict with multiuser access.
If you just need the column to order the table you can use a sequence and then order you table by template_id, order_by (generated by a sequence).
In this way you will not have a problem with multiuser access. Do you care that order_by column is not starting from 1 for each template_id and it has "holes" in the sequence for that template_id?

Javascript - is there something like an "active row count" property??

Lets say I have a tabular form. Every time I use the form, the # of rows returned by the query will vary. Maybe first time I go to the page, the select statement returns only 5 rows, but the next day it returns 25 rows.
Is there some type of system variable to stores the # of rows visible on the page at a given time within this tabular form?
I realize that if I have an tabular form item with an id of f03 for example, then on each row it will be referenced as f03_0001, then f03_0002 on the next row and then f03_0003 on the next row etc...
In pseudocode, here is what I want to do:
For i = 1 to ACTIVE_ROW_COUNT (assuming this is the # of rows in the HTML table)
perform some operation on 'f03_000' + ACTIVE_ROW_COUNT
Do you see what I'm after? I checked the APEX api, but I couldn't find such a property. It seems like you can't do much if you can't figure out this current index # or the max on the page.
Also, I tried playing around with the "this" keyword in hopes of finding a pointer to the "current item" that would have triggered the onchange event, but no luck either.
Thanks in advance.

Hi:
Within javascript you can reference the columns of the tabular form as
<script>
col1 = document.forms0.f01; // the first updateable column of your report
alert (col1.length) ; // number of rows
</script>varad

Collection inaccessible from Before Header process

Hi,
I have a form based on the Matrix Order application. There's a collection-based report with a bunch of text fields that can be updated and a column with a "Remove" item that basically calls a conditional Before Header process to remove the item from the collection. What I want to do is update the collection (with the values that the end-user may have entered in the updateable columns) prior to removing any item. So when the user clicks on "remove", first I do an update_member_attribute and finally I remove the item the user chose. My problem is that the updates are skipped altogether; the code is not even executed, but the removal is. It's like the collection doesn't exist at one point, but exists the next. I added an insert into a dummy table to see how many items the collection had, and it returned zero. However, the delete worked just fine. Can you have a look at my code, to see if I'm missing something obvious? Thanks a lot!
Here's the code in the Before Header:
--Here we find out how many rows in the collection
select count(*) into c from apex_collections where collection_name = 'ORDER';
insert into table1 (column1) values ('to update '||i); --This inserts "to update 0" into my dummy table.
--Update collection - nice try!
FOR x IN 1..APEX_APPLICATION.g_f01.COUNT --This code is skipped; according to the previous select, the collection has 0 rows
LOOP
c := x;
apex_collection.update_member_attribute
( p_collection_name => 'ORDER',
p_seq => APEX_APPLICATION.g_f03 (x),
p_attr_number => 4,
p_attr_value => APEX_APPLICATION.g_f01 (x) );
apex_collection.update_member_attribute
( p_collection_name => 'ORDER',
p_seq => APEX_APPLICATION.g_f03 (x),
p_attr_number => 6,
p_attr_value => APEX_APPLICATION.g_f02 (x) );
END LOOP;
--This works fine, however!!!
apex_collection.delete_member(p_collection_name => 'ORDER', p_seq => :P612_SEQ_ID);
I've tried placing the code in a "On submit" process but it's never executed. I guess that the links on report columns are not considered submits, just redirects or something else.

Multi row update not occuring

I have created a tabular form using the wizard. This form will show three columns (and in addition a checkbox). I would like this form to be updateable in only certain instances. Because of that, I select the columns twice. I make one of them updateable, and the other read-only. Then I have a conditional display for the columns, so that the updateable columns are shown if a status variable in my page is 'EDIT' and the read-only columns are shown otherwise.
The problem is that the multi row update does not occur. If I show one of the read-only columns when in the edit mode, the update is done. Also it is executed if I show one of the editable fields when the page is not in edit mode. But when I show only the editable fields in edit mode, and only the read-only fields when in read-only mode, the process is not run.
What can I do about this? Why doesn't the multi row update occur?

An alternative is to control the updates by controlling the buttons. Only show the submit/update button if the status on the page is "EDIT".

Radio Group With Submit.

Apex 3.2
I have an updateable report based on a collection.
One of the columns is a radio group and is the only updateable column
My code for the column is currently
apex_item.radiogroup(7,seq_id,c008)
I also have a button that fires an update process.
Ideally, I would like to get rid of the button and fire the update, after the user has changed the radio group.
So I changed my code to
apex_item.radiogroup(
              7
            , seq_id
            , c008
            , null
            , null
            , null
            , 'doSubmit(''SUBMIT'')'
            , null
            , null
            , null)
If I click on a different radio group nothing happens.
If I then click on another one, the update fires, but with the value of the previous radio.
Do I need to add something else to
'doSubmit(''SUBMIT'')'
Thanks
Gus

Submitting a page or navigating to another page is not an appropriate action to take on clicking a radio button checkbox:
Setting or clearing a checkbox changes the checkbox's state with no other side-effects. Violating this guideline by associating additional actions with the change of state frequently confuses users, because they are used to configuring data in entry controls such as text boxes, radio buttons, and check boxes and then invoking an action control such as a push button to initiate the action to process the data.
Use radio buttons to select items or options before initiating a submit using an appropriate control. Use buttons and links to submit and navigate to other pages. This enables users to consider their choice and change it before submission.

Master Detail in AdvancedTable - Data is not Saved in VO

I have a Master/Detail region as a table-in-table. The outer and inner tables each have a different VO that is related via a VL. The inner table has updateable columns. However, when the hide/show links are clicked on the master, the changes on the detail columns are not maintained. Do I have to manually commit the data for the inner table's VO to the database so that subsequent queries on the detail rows reflect the newly updated columns? Please advise. Thank you.

Is it possible to create a creative cloud team between educational customers and normal customers?

education team work together with "normal" team?

Hi:
There is another method that I have used widely with great success. It is similar to using collections.
First I generate a report that will give me the columns I want. Then, any column that I want the user to be able to update, I change it from a standard report column to an text item. This then enable the user to set values as they want them.
Once the user has updated the report, I can update the table based on the values entered. For example:
UPDATE order_details_holding set
size1 = WWV_FLOW.G_F01(i),
size2 = WWV_FLOW.G_F02(i),
size3 = WWV_FLOW.G_F03(i),
total_quantity = v_line_total,
total_cost = v_line_total * v_price
WHERE product_id = :P42_PROD_ID and row_id = v_row; ....
VVW_FLOW.G_F01() gives you access to the first updateable column.
If you need more details let me know, or have a look at the Matrix Orders application. I don't use the collection itself, but just the idea of the updateable columns in the report.

Bruce
