How to combine tabular form and text area in one page? - oracle-apex

I have a page, containing tabular data(region type SQL Query (updateable report)). It only updates existing rows using Submit. The wizard created ApplyMRU process. It works fine. But now I would like to place a text area in the same page, which will be bound to different table and will get updated once the same Submit button is pressed. How can I accomplish it?
I've created item for text area, but not sure what type of source I should set. Database column doesn't let me specify table. Also I guess I need a second after submit process, but not sure which one.

Keep your existing ApplyMRU infrastructure for the tabular form, and just define a second PL/SQL process that executes during page submit that will do whatever it is you want with your text area, eg:
insert into notes (id, text) values (:P1_ID, :P1_TEXT_AREA);
Take note of the order of the processes, as you may want to execute one before the other.

How can I set the Interactive Grid and its form in same page on Oracle Apex 18?

I set the Interactive Grid and its form in same page. For exampe:
The name of table is TEAM, and it has columns like TEAM_ID, TEAM_NMAE, DESCRIPTION.
These contents are displayed in Interactive Grid, and they can't be edited in interactive grid alone.
I added Row Selector in Interactive Grid, set to select only one row at a time.
As you can see in above picture, below the page I set the form that displays contents from the seleted row in the interactive grid. I also added save, create, delete buttons in the form region.
So, I want to edit the table's contents in one page when clicking the button.
I can just display table's contents in items using '$s("P3_TEAM_ID", team_id);' function, but still, I can't apply changed items to real table (in the interactive grid).
In this case, how can I make the form and interactive grid work as I think?
Your gonna need to do some custom saving.
Display the data with some javascript $s
Then have a process that manually saves the page items into the DB.
UPDATE table
SET name = :P1_NAME
,address = :P1_ADDRESS
...
WHERE id = :P1_ID;
Something like that. Not that hard to do, just set it into processes when a save button is clicked.

Oracle APEX - Reusable Pages?

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.

Mapping user spreadsheet columns to database fields

I’m not sure where to start on this project. I know how to read the contents of the excel spreadsheet, I know how to identify the header row, I know how to loop over the contents. I believe I have the UX portion worked out but I am not sure how to process the data.
I’ve googled and only found .Net solutions but I’m looking for a ColdFusion/Lucee solution.
I have a working form allowing me to map a user's spreasheet column to my database values (this is being kept simple for this post; user does not have direct access to the database).
Now that I have my data, I'm not sure how to loop over the data results. I believe there will be several loops (an outer and an inner). Then of course I also need to loop over the file contents but I think if I can get the headings mapped out,I can figure out the remaining.
Any good links, tutorials, or guides would be greatly appreciated.
Some pseudo code might be enough to get me started.
User uploads form
System reads headers and content.
User is presented form with a list of columns from their uploaded spreadsheet to match with available database fields (eg “column1” matches “customer name”.
User submits form.
Now what?
UPDATED
Here is what the data looks like AFTER the mapping has been done in my form. The column deliiter is the ::: and within the column the ||| indicates the ID associated with the selected column value. I've included the id and the column value since I plan on displaying the mapping again as a confirmation. Having the ID saves a trip to the database.
If I understand correctly, your question is: how do you provide the user a form allowing them to map their spreadsheet columns to that of the database
Since you have their spreadsheet column names, and you have the database column names, then this problem is essentially a UI/UX problem. You need to show both lists, and allow the user to map them. I can imagine several approaches to this. My first thought would be some sort of drag/drop operation, as follows:
Create a list of boxes, one for each field in your database table, and include the field name in (or above) the box. I'll call this the db field list. Then, create another list for each column from the spreadsheet, which I'll call the spreadsheet column list. The user would drag/drop items from the spreadsheet column list to the db field list.
When a mapping has been completed by the user, you would store the column/field names in as data for the DOM element of the db field list box. Then upon submission, you would acquire the mapping data by visiting each box and adding it to an array. Then you would serialize that array into JSON and send that to your form submission handler.
This could be difficult or easy, depending on your knowledge of UI implementations using JavaScript. jQuery makes this easy (if you know jQuery). There's even a jquery UI plugin that does this: https://jqueryui.com/droppable/.
A quick search for javascript drag drop would help, and here's a few articles I found:
https://www.w3schools.com/html/html5_draganddrop.asp
https://medium.com/quick-code/simple-javascript-drag-drop-d044d8c5bed5
You would also need to submit the array of mappings using javascript. You could search for that as well, and here's an article I found:

Formula help on IF ELSE on Smartsheet

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.

Copy Records in Oracle Apex

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.
