How to display and update the records I have added/insert in the Apex interactive report - oracle-apex

Question

I've created an interactive report to add/update/delete employee info records in custom db table.
My end user requirement is upon entering the employee number in the EMPNO field, all the details from the oracle standard table such as employee name, marital status, gender, bday must be auto generated in the form and they will only manually input the location name and mode of exit.
Now I created 3 pages: 1.home page, 2.add page, 3.update page
On page 1 (home page)
I have here the select SQL
with checkbox
On page 2 (add page),
In the page processing portion
I have
EventAddRecord
Source: db , plsql code
Here's my sample code:
BEGIN
INSERT INTO EMPINFOTBL
(PERSON_ID,
EMPLOYEE_NUM,
EMPLOYEE_NAME,
MARITAL_STATUS,
BDATE,
GENDER,
LOCATION_NAME,
MODE_OF_EXIT
)
VALUES
(SELECT PERSON_ID FROM
PER_PEOPLE_X WHERE EMPLOYEE_NUM = :P2_EMPLOYEE_NUM),
(SELECT EMPLOYEE_NUMBER ID FROM
PER_PEOPLE_X WHERE EMPLOYEE_NUM = :P2_EMPLOYEE_NUM),
(SELECT FULL_NAME FROM
PER_PEOPLE WHERE EMPLOYEE_NUM = :P2_EMPLOYEE_NUM),
(SELECT MARITAL_STATUS FROM
PER_PEOPLE WHERE EMPLOYEE_NUM = :P2_EMPLOYEE_NUM),
(SELECT DATE_OF_BIRTH FROM
PER_PEOPLE WHERE EMPLOYEE_NUM = :P2_EMPLOYEE_NUM),
(SELECT GENDER FROM
PER_PEOPLE WHERE EMPLOYEE_NUM = :P2_EMPLOYEE_NUM),
:P2_LOCATION_NAME,
:P2_MODE_OF_EXIT
);
END;
Buttons
SAVE with dynamic action
When click add button if True submit page
Now my problem is how to do the update when I click the check box,
I want my record to be displayed in the form because currently when I click the check box the form is null

Answer 1

To create a new record (using Page 2), you'd create a select list item which is based on per_people table; you'd display any information you want, but you'd return employee ID:
select full_name as display_value,
employee_num as return value
from per_people
order by full_name;
After selecting desired person, enter values into P2_LOCATION_NAME and P2_MODE_OF_EXIT items. When you hit the "Save" button (which submits the page), run the process (I modified what you wrote; should be way simpler):
INSERT INTO empinfotbl (person_id,
employee_num,
employee_name,
marital_status,
bdate,
gender,
location_name,
mode_of_exit)
SELECT person_id,
employee_number,
full_name,
marital_status,
date_of_birth,
gender,
:P2_LOCATION_NAME,
:P2_MODE_OF_EXIT
FROM per_people
WHERE employee_num = :P2_EMPLOYEE_NUM;
As of updating existing values: I'd again suggest you to use the Wizard as it creates everything you need - form page is based on empinfotbl table, while "Edit" button in Interactive report sends the ID value to form page whose pre-rendering process fetches data related to employee identified by passed ID.
If you created your own page, you'll have to do it all yourself.
You said:
I want my record to be displayed in the form because currently when I click the check box the form is null
Form items are empty because Apex didn't know what to fetch. As I said: pass ID value, create pre-rendering process. Or start over with the Wizard (I prefer that option).

Answer 2

#Littlefoot has given a perfect answer already, here are just some extra steps that might guide you to a solution (it's the "or start over with the wizzard" piece from Littlefoot's answer). I'd suggest looking how apex generates its pages when you do it out of the box. Just for testing, follow these steps
Create a new page of type "Interactive Report" and make sure to check the "Include Form Page" attribute
Give the form page a name and select "PER_PEOPLE" as table/view name
In the 2nd page of the dialog, select the primary key column of PER_PEOPLE: person_id
Click "Create Page"
You now have a working form and report that you can further customize to your specific requirements. It should give you a good idea of how a form and a report is generally configured in APEX and it saves you a ton of time
Notices how in the report page:
The edit link has the form page as target and passes the id
The CREATE button has the form page as target without the id
In the form page
No custom code is needed to initialize the form data for the current record. Instead the native process of type "Form - Initialization" is used.
No dynamic actions are used to perform the inserts - for a form that is a bad practice. Avoid it.
No custom code is needed to perform the inserts or update. Instead the native process of type "Form - Automatic Row Processing" is used.
Study these pages and apply similar logic to your own pages. It'll be a better app.
