I am trying to update a collection and a table.I got some example code and installed on oracle.com, but I just can't seem to get it to work.I always get an errorORA-20001: Current version of data in database has changed since user initiated update process.I think the problem lies with comparing the checksums, but I cannot spot the mistake
View 2 RepliesMy scenario is I need to insert into History table when a record is been updated into a tabular form(insert the updated record along with the additional columns Action_by,Action_type(Like Update or delete) and Action Date Into History table i.e History table contains all the records as the main table which is been visible in tabular form along with these additional columns ...Action_by,action_type and action_date.
So now i dont want to create a befor/after update trigger on base table rather i would like to create a generic procedure which will insert the updated record into history table taking the page alias and pade ID as the parameters(GENERIC procedure is nothing but whcih applies to all the tabular forms(Tables) contained int he application ).
I am trying to create a collection using bind variables in APEX 4.1. I have the following procedure but all I get is an error in the debug page DOH ORA-20104:
create_collection_from_query_b Error:ORA-01006: bind variable does not exist
My code is
DECLARE
l_names wwv_flow_global.vc_arr2;
l_values wwv_flow_global.vc_arr2;
l_names(1) := 'EXPENSE_FROM';
l_names(2) := 'EXPENSE_TO';
[code]....
Note, I'm using APEX 4.1.1
The scenario is that I have tabular form that was manually created from a collection; the collection name is "COMPANY"
Within this tabular form, I have number of selection lists (apex_item.select_list) and for each, I fire off a JavaScript based on the "onchange" event (e.g.,'onchange="updateCollection(' || seq_id || ', 10, this.value)"'); updateCollection is a custom function I created. Right now, all it does is alert me with the specifics of the of the selection list. As a further example, if I select "Google" from the selection list, sequence id would be "1", attribute number would be "10" and attribute value would be "Google"
Within this JavaScript, I would like to update the value of this associated element in the "COMPANY" collection. Ideally, I would like to directly call this:
APEX_COLLECTION.UPDATE_MEMBER_ATTRIBUTE(p_collection_name => "COMPANY", p_seq => 1, p_attr_number => 10, p_attr_value => 'Google') but I could not figure out how to do this.
in our application, we're uploading .xls files with several (and heavy) sheets.
In order to get better performance, is there any way to load just one of them?
db11gxe , apex 4.0 , firefox 24. I want to do automatic row fetch when the value of a select list changes ?but first i should ofcourse create a tabular form to fetch the data into it , but what i want is ,if i fetch 2 rows then the report contains only two rows , if i fetch 3 , the report contains only 3, if i fetch nothing , the report has nothing ?
View 0 Replies View RelatedThe values in the page item dont get submitted hence generate errors in my application , in apex 4.2 using collectionEg.
apex_collection.add_member(p_collection_name => 'ORDER', p_c001 => :P56_product_id, p_c002 => :P56_product_name, p_c003 => :P56_list_price, p_c004 => 1);
Can there be a reason why ?
My collection is not working as expected, what could be the issue here. This is what i did,
1. I created a collection in a process to fire on page load
if apex_collection.collection_exists(p_collection_name=>'MMMM') then
apex_collection.delete_collection(p_collection_name=>'MMMM');
end if;
APEX_COLLECTION.CREATE_OR_TRUNCATE_COLLECTION(p_collection_name => 'MMMM');
2. On my page i have a text field P1_text1 when i enter value into text field like ="sample data" i want this data loaded into my collection, so i created a button and added a process(on submit - before computations...) so it should insert into the collection when i click the button but no data is loaded, process:
APEX_COLLECTION.ADD_MEMBER(
p_collection_name => 'MMMM',
p_c001 => :P1_TEXT1,
p_c002 => 'TESTDATA' );
3. when i run the below query it shows "no data found" ,
SELECT c001,c002
FROM APEX_COLLECTIONS
WHERE collection_name = 'MMMM';
I created one collection report and in the report when i click on the next >> then the report will show the next columns to enter data in some columns but the data which i entered before going to next will not get retain (data is getting lost) when i come back by clicking << previous but i want the data to get retained even when i click on next >> or previous << in report so that i can enter large amount of data at a time in the report columns by clicking >> & << and click on submit button to save all the data.

View 2 Replies View RelatedWe have several prod instances and many applications on each of these... and interactive reports saved by many users.Each prod application have its own ID, distinct from the dev application ID.
Until today I used the apex_application_install inside the first wokspace only, and it works fine, but I need to update applications on every instances. It seems the only way to keep a saved report during an update is to use the same application Id (use the app n°200 to overwrite the n°200).So it means the only available method is : release the dev app on the dev workspace ; export 50 apps from it and import those 50 times, maybe more in the future.

I have two SQL reports on the same page.
Those SQL reports are built with apex_items. Afterwards I'm updating them with a manual process (apex_application.g_fxx for ..loop). I'm using different IDs on both reports for the apex_items.
It's working fine for the first report displayed. But not for the second one. If I swap the two reports, it's always the first that will be updated.
Does it mean that we cannot use the apex_application to update more than one report and that I have to use a page per report?

I have a report that comes from SQL Query (updateable report). I'm using the apex_item.text and apex_item.hidden on fields. I'm using a button to submit and after submit process to add some logic that I need.
There could be 1 - 10 records in the report. There is only 1 field that is needed to enter a value, but the value of this field determines the value of another field. I think that I can do this with a submit button and an after submit process where I loop through all the records. I think I have this handled.
This is the question
When the value of that field is changed then the value of another field in the same row changes immediately. All the examples I've seen so far are for a single record and that doesn't work for us.
I guess this is a MRU process but I haven't seen an example where a dynamic action is possible on a Multi Row Update.
As all of you know, In the Apex, when you create a form with report in the page, you are able to insert and edit data. But when you edit the data, the data will be modified in the same row. In other word, you loose the old data.
What I need to do is: I have revised_num field and production_date field. I want to create a form with report and insert and edit data as is in the apex and insert 0 to the revised num until production date is null. But when production date is not null, then from that point, I want to insert data to another row and modify revised num to 1. and I want the revised num be incremented by 1 each time the user modifies the data after the production date is not null.I don't know where I should start.
Is there some simple solution how to send email to user with link ('I don't want to receive emails from you in the future') ?
The link should contain some key information for each user.
If user click the link - update of the table should be done. (some IDC updates from 'Y' to 'N').

I have a procedure I need to feed a number into in order to generate some thumbnails.
I'm trying to automatically update the value every time a new row is inserted but I'm having trouble with the code.
DECLARE
varInt NUMBER :='SELECT MAX(IMAGE_ID) FROM IMAGES';
begin
create_blob_thumbnail(varInt);
end;I get the error +'ORA-06502: PL/SQL: numeric or value error: character to number conversion error'+
If I run the query SELECT MAX(IMAGE_ID) FROM IMAGES, it returns the last row ID I created just as it should. The create_blob_thumbnail(varInt) procedure works fine if I manually put in a number.
I followed the directions to print a report using this documentation [URL]....where I setup a report query and a report layout and then add the url to a button that when clicked opens up the report in my chosen format. This all work very nicely. However, I need to update the table behind each record that gets printed and I cannot figure out how to couple the print request and an update process in APEX.
View 5 Replies View RelatedGetting starting with diving deeper into APEX and reading the developers guide all 800 pages of it! Thing is I'd like to get started with some of the more interesting stuff.
I have created a form page based on the "Form on a Table with Report". The report part looks fine. What I'd like to do now is use an API I've built to change how the insert and update works. So when the submit button is pressed it rather performs an API call to the procedure/function.
1. Should the API be a function or procedure. In my playing around I saw that a procedure might work better or easier to implement
2. How would I go about creating a call for the button to use instead of the current processes?

Let's say that we have an order entry app and the price and quantity items are already populated. We now want to show the user the extended price (the product of the first two items). the extended price would automatically display after both the quantity and price items are entered. I'm assuming that would require some kind of client-side processing. I imagine server-side processing is simpler, so I'll lean in that direction. I'm sure we've all seen web sites that require you to click a button for the order totals to be updated. I'm okay with that approach, but I haven't quite put all of the pieces together. Here's what I came up with.
A region button was added to trigger the updating of the extended price. The button's "Action When Button Clicked" is to submit the page. Under "Page Processing", a process was created to do the calculation with the recipient of the product being a page item. From debug code in the procedure, I can see that the item containing the extended price was, indeed, modified. But the new value doesn't display in the field and the Session window shows that the value of the item didn't change.
I must be missing something. The debug code says the item value was updated. The Session window says it wasn't updated. What gives? What did I do wrong and what needs to be done to correct this?
I have created a simple page with a tabular form built on a view. The view is on top of a collection that is created when the page is ran. I added a tabular form column validation. I then was going to add a pl/sql process to handle the updates into the db, but before I did that I wanted to delete the ApplyMRU that was created when I first created the tabular form because it does not make sense on my view. When I went to delete the MRU it gave me an error saying "Multi Row Update processes can't be deleted as long as there are validations defined for the tabular form".
I have searched for an answer on this, but so far I have not found much. I am hoping it is something simple that I am missing. I even tried deleting the MRU first and then add the validation, but then it gave me another error about "Tabular form validations require multi-row update processes" I know this was possible in 4.1, but now I am trying it on 4.2

I've started using Apex 4.2(new to Apex). I have built a form based on a table with a date column on it. The form allows update on all fields/columns of the base table. For the date field/column, the goal is to present the user with sysdate on load and update the date with sysdate if the record is changed any of the fields. How can I accomplish this?
I got a bug related to update information in APEX.
the situation occurs when I go to update a record the button Apply changes disappeared, it shows me only the button create, so when the user click on it, it creates a duplicate.. so how can i have the button "apply changes" back?
Application Express ver. 4.1
I have created a form. Some of the elements are hidden such as updated_by and update_date. I have provided the default values for these attributes as pl/sql expression in the "default section" (Application->page->edit page item). I am using the Process Row process that is automatically created when a form is created.
The problem is when I click the update button, the updated_by and update_date is passed as null values which throws an error from the database.
1 - i want to ask few things as i m new to apex, i am using apex 4.1, and created 3 select list and a button in selecting of parameter,
1 select list : select area
2 select list: select product
3- select list - size of the product
i want to generate Ids for the following. for that i created query for INSERTING RECORD FROM ONE TABLE TO ANOTHER , generation the ids when button pressed "Generate" after selecting parameters,
Now where i call that QUERY on button ? because when i create button its gives me option to submit, defined dynamic action, etc, where i call the function name id_generation when button pressed?
2- second thing i created tabular " select user_id, product_name, product_type from product".
By default check box list are create delete submit button are created, first when i insert record it saves that was fine, e.g i entered 50 records and afterward i want to update only one record, e.g there is a record product name = box, if i change it to box small and click submit then it saves all the page means all 50 records,
I want to submit only that record that i changed, for that i use the logic that only those records should be updated which are checked but the user. how will i do this ?
I'm editing, say, list of my employees in a tabular form opened in Skillbuilders Modal Page. I have to execute same javascript code after the changes in the tabular form have been submitted.
I've tried using a Dynamic Action fired on Page Load, but that gets executed before the update is completed.
I'm trying to update a number field on an apex page by summing up the values of multiple page items. I've tried to follow this tutorial
[URL]........
especially the "Create a Set Value Dynamic Action Using PL/SQL" part.
In the tutorial example they return an page item value P3_SAL multiplied by a multiplier they've determined by another page item's case. What I want to do is much simpler in that I just want to add up multiple page item values and then display them in a number field at the bottom of the page.
so the code I tried to use based on the tutorial is in the tab: Home >Application Builder>Application 103>Page 3>Edit Dynamic Action>Create / Edit Action
Set Type: PL/SQL Function Body
PL/SQL Function Body:
BEGIN
return :P3_ITEM1+P3_ITEM2+P3_ITEM3;
END;
Page Items to Submit: P3_ITEM1,P3_ITEM2,P3_ITEM3
But it gives me an error that I need to declare the identifiers, yet it works if I only use one item and I can perform any arithmetic.
i.e.
BEGIN
return :P3_ITEM1+1000;
END;
I am experimenting with the 4.2 version of Apex at URL.....
I have created a tabular form (based on a view with an instead of trigger) and have restricted this form to "Update only" mode. Whenever I modify a field value and submit the change I get the error "Current version of data in database has changed since user initiated update process".
I have a table which contain match ID , team and the state of the team Each match ID can contain only two teams and I did trigger for that, what I want to do is when the user update the table and add the state after the match is played,, the other team state is changed to the opposite ,, except for the draw which both of them should have the same state..For example when team 1 state is set to win, team 2 which have same team 1 ID, should be updated to lose....
I want to create a trigger to do that,,I tried to do a trigger but not working
create or replace TRIGGER "UPDATE_STATE"
AFTER UPDATE ON "SPORT_MATCH"
FOR EACH ROW
BEGIN
if (:new.state = 'Wins') then
UPDATE SPORT_MATCH SET STATE = 'LOSES' WHERE SPORT_MATCH.MAtchID = :NEW.MATCH_ID and Team != :New.Team;
END IF;
END;I got this error
•ORA-04091: table MATCH is mutating, trigger/function may not see
I have a collection, which I can update. Before I do the update I need to compare checksums and only update where the checksums are different. Tried various things but cannot get it to function.
