I have created a page with pre-rendering to fetch rows from employe table using auto dml processing(legacy).
Post this all page items are defined and aligned with respective columns in source.
After this i created 4 region buttons-> create, cancel, delete and save.
I can see all buttons except save.
Save properties-> SQL UPDATE on submit.
Processing->
Get PK
Process row from Employee tabe-> lock row for insert update and delete.
What else do i need to do or where am i going wrong?
This question is already answered by its author.
Fixed on my own 😊 – Vini

I want to use simplepaginate from livewire but I have a problem.
I'll explain, I have a delete button on each row of the table, when I go to the last page with paginate I have only one row, if I click on the delete button it works normally but my table becomes empty and the message of 'no record in table is displayed' yet the database still contains data.
You should go back to page one after each deletion.
To do so you can use the $this->resetPage(); that is added by the Livewire\WithPagination trait
We have some tables in our database that all have the same attributes but the table is named differently for each. I'm not sure of the Architect's original intent in creating them in this way, but this is what I have to work with.
My question for all the expert Oracle APEX developers: is there away to create a reusable page that I can pass the table name to and that table name would be used in the reporting region and DML processing of that page?
I've read up on templates and plugins and don't see a path forward with those options. Of course, I'm new to webdevelopment, so forgive my ignorance.
We are using version 18.2.
Thanks,
Brian
For reporting purposes, you could use a source which is a function that returns a query (i.e. a SELECT statement). Doing so, you'd dynamically decide which table to select from.
However, DML isn't that simple. Instead of default row processing, you should write your own process(es) so that you'd insert/update/delete rows in the right table. I've never done that, but I'd say that it is possible. Basically, you'd keep all logic in the database (for example, a package) and call those procedures from your Apex application.
You could have multiple regions on one page; one region per table. Then use dynamic actions to show/hide the regions and run the select query based on a table name selected by the user.
Select table name from a dropdown or list
Show the region that matches the table name (dynamic action)
Hide the any other regions that are visible (dynamic action)
Refresh the selected region so the data loads (dynamic action)
If that idea works let me know and I can provide a bit more guidance.
I never tried it with reports, but would it work to put all three reports in a single page, and set them via an Item to have Server-Side Conditions that decide what gets shown in the page? You'd likely need separate items with a determined value for the page to recognize and display.
I know I did that to set buttons such as Delete, Save and Create dynamically, rather than creating two or more separate pages for handling editing of certain information. In this case it regarded which buttons to shown based on a reports' primary key being sent to said "Edit" page. If the value was empty, it meant you wanted to create a new record (also because the create button/link sent no PK). If said PK was sent (via a edit button/link), then you'd have the page recognize it and hide the create button and rather show the edit button.
I want to have a condition where IF Delivered column checkbox is checked, then that whole row will be deleted. Is that feasible?
How can I start with it?
Formulas can't change the condition of an item (like a row), only the value in a cell. So, in other words, you can't delete a row with a formula.
You "could" do this with an external script using the Smartsheet API, but you'll want to take situations that #Ken White mentioned in the comments into account. Your script should make sure that there is a way for users to recover the deleted row if the box is checked by mistake.
There are a couple of ways this might be possible. If you set up a default filter on a sheet to always load rows where complete box is unchecked, then, if you checked off a task or two and reloaded the sheet those tasks would not be visible the next time it loads.
To do this:
Create a new filter.
Title it and check the Share Filter checkbox
Set the criteria to the checkbox is unchecked
Then click okay
Save the sheet to save the shared filter.
Click on SHARE
Scroll down and click edit next to the default view
Set the filter to new filter you saved
Save.
Check off some boxes and save the sheet.
Reload the sheet and the completed items will not be visible.
I need to copy selected row values and store as a new record.
I am using Oracle Apex 4.2 and Tabular Form.
I need to use checkbox to select the rows and button copy. When i select multiple rows followed by click copy button to copy all the selected row values as new rows and save.
Can anyone Help
Copying Records Through an APEX Tabular Form Input
The idea of cloning existing records from a single table through an Oracle APEX Tabular Form works without much interference with the default design that you can set up through the APEX wizard for page region content.
Build a table with an independent primary key.
Suggested to include two auxiliary columns: COPY_REQUEST and COPIED_FROM for running copy operations. Specific form elements will map to these columns on the tabular form that will be set up.
Build an Oracle stored procedure that can read which records need to be copied. This procedure will be invoked each time the SUBMIT button is pressed.
(optional) Consider including a suppression of step (3) in the event that there is nothing to process (i.e., no records marked for copying).
The Working Table for Receiving Input: COPY_ME
TIP: You will have an easier time if you use the standard TABLE creation wizard. Designate CUSTOMER_ID as the PRIMARY_KEY and have APEX create its standard auto-incrementing functionality on top. (sequence plus trigger set up.)
Here's the sample data I used... though it doesn't matter. You can put in your own values and be able to verify what happened easily.
The Heavy Lifting: The Stored Procedure for Cloning Records in COPY_ME
This procedure works with 1 or more records at a time with a special identifier in the COPY_REQUEST table. After the task is done, the procedure cleans up and resets the request value again.
create or replace procedure proc_copy_me_request is
c_request_code CONSTANT char(1):= 'Y';
cursor copy_cursor is
SELECT cme.CUSTOMER_ID, cme.CUSTOMER_NAME, cme.CITY, cme.COUNTRY,
cme.COPY_REQUEST
FROM copy_me cme
WHERE cme.COPY_REQUEST = c_request_code
FOR UPDATE OF cme.COPY_REQUEST;
BEGIN
FOR i in copy_cursor LOOP
INSERT INTO copy_me (customer_name, city, country, copied_from)
VALUES (i.customer_name, i.city, i.country, i.customer_id);
UPDATE copy_me
SET copy_request = null
WHERE CURRENT OF copy_cursor;
END LOOP;
COMMIT;
END proc_copy_me_request;
There is also a column that can be hidden. It tracks where the record was originally copied from.
Note that the cursor is using the FOR UPDATE OF and WHERE CURRENT OF notation. This is important because the procedure is changing the records that are referenced by it.
APEX Page Setup Instructions
Set up a standard FORM type page and choose the TABULAR FORM style. Follow the set up instructions, taking care to map the correct primary key, and also to the PK sequence object created with the table in the previous steps above.
This is what your page set up will look like after these steps are completed:
EDIT The COPY_REQUEST Form Value:
Under the column attributes section, change the Display As option to "simple checkbox"
Under the list of values section, put a single value under the LOV Definition: Y (case sensitive in either way... just be consistent)
EDIT The COPIED_FROM Form Value:
Under the column attributes section, change the Display As option to "Display as Text(Saves State)". This is just to prevent users from stepping on this read-only field. You could also suppress it if it isn't important to know.
CREATE a New Process: Execute Copy Procedure
This is the bottom of the same configuration page, there are very few things to change or add:
Demonstration: Screenshot of COPY_ME Tabular Form Page in Action
The first screenshot below is before the page is tidied up and the checkbox control is put into place.
Plug in some test data and give it at try. The Page Process created in the step above conditionally invokes the stored procedure that processes all copy requests made at the same time when the SUBMIT form button is selected.
COMMENTS: If you spend enough time tinkering around with the built-in wizards in Oracle APEX, there are opportunities to learn new design patterns and process flows compatible within the tool. Adapting your approach can reduce the amount of additional work and frustration.
I have a field defined in my table as DATE and want it to automatically populate with the current system date when someone access the update form in my APEX application. But the date doesn't update. It was working when I first added it, but now when you pull up the update page it only shows the date that's in the table.
In Oracle, a default on a column means that if a record is inserted into the table without mentioning that field, then use the default. My guess is that since the field is displayed on your page, you are writing NULL or spaces to it, so it is definitely included in the insert statement.
So you need to either take it off the page, add an update trigger, or even better, write a process in Apex to update it whenever the record is modified -- perhaps an After-Submit computation.
