Oracle Apex radio group - oracle-apex

Environment: Oracle DB 11gR2.
Framework: Oracle Apex 5.1
I have a table with Column Product_id,Monthly_rate and Yearly_rate
When user will select Option for- Monthly
Then I want to pass below three values in another pages according to selection
Product_id
Monthly -- User select this option
Monthly_rate
Similarly for Yearly selection I want to pass
Product_id
Yearly -- user select this option
Yearly_rate.
I want to use radio group How can I achieve this?
Thanks in advance

When you declare a Radio Group in Apex the selected value will be stored as the Item Value on Submit. As with every other Item in Apex you can then reference that Item Value from all other Pages with this Syntax:
:P1_MY_RADIO_GROUP
Where 1 is the Page ID and MY_RADIO_GROUP the Item Name.
When you want to maintain that selection in another Radio Group just use the Item Value as the Source for those Radio Groups.

Oracle Apex 22.21 - Chart Page - Bar Type - How to return a range of date values based on user input

I have a table ORDERS which contains column ORDER_DATE. I have created a Chart as a Bar type.
Right now, the chart returns all the orders because I did not specify a Maximum Rows. The date on the x-axis and the number of orders on the y-axis.
How can I add a form for the user to select a range of dates and return only the values for those dates?
Example:
Doesn't necessarily have to be a calendar. A dropdown is fine as well. Or even a 'text' input since that is the easiest way.. I just need to know how to go about creating this feature. Your help is appreciated. Thank you.
First create a page item as date picker or some other plugin you already have to let users select a date or date range. (make sure that when user selects a date, the page item value is set by using a dynamic action or by a setting that your plugin has (set item value after selection kind of setting) )
Then create a new view with the source of your ORDERS table but it should have a where statement as it filters records by your page item such as:
select count(1)
from ORDERS
where order_date between :P1_DATE_FROM and :P1_DATE_TO
Set the source of the chart to this new view.
After user sets a value, refresh the chart by a dynamic action if it is not refreshed automatically.
In summary, the idea is to make your chart's source filtered by page items that users can change. Then refreshing the chart so that the new page item values are effective.

Get Select list Item value in IG report column for DML operation

I have a Select list filter on the top of the page. I want its return value to get into any column which I create in IG report automatic DML process.
Suppose, Select list has a value "Step", when I add a row in IG report, that value should be saved into DB for one column which is hidden on UI.
I tried but sometimes it stores the value which I selected in Select list item as my last selection not the current one. Do I need to create Application item for this? Please help. TIA
In this case there is a table ig_tickes with a status column. On the page there is a page item P131_STATUS (select list) with values "OPEN" and "CLOSED". There is an interactive grid on table ig_tickets with column STATUS hidden. Functionality is that user selects a value from the select list and then clicks "Add Row".
Give the interactive grid a static id of "tickets"
Create a dynamic action on change of P131_STATUS with a true action of type "execute javascript code" and code:
var model = apex.region("tickets").call("getViews").grid.model;
model.getOption("fields").STATUS.defaultValue = apex.item( "P131_STATUS" ).getValue();
That's all there is to it.

Oracle Apex Dynamic action not working for form items

I have a form with items P1_APP and P1_USER.
P.S. P1_USER is select list.
Display John
Return 1
Display Andy
Return 2
I need to disable when user selects John.
When P1_USER = 'John', P1_APP should get disabled which is a multi select list.
I created dynamic action on P1_APP, True Action= Disable,Affected element P1_APP
Client condition : Item =Value
Item= P1_USER
Value= John
However this is not working.
I have used similar logic to disable interactive grid items and was able to do so. Why is this not working for form?
EDIT: In Value now i am putting 1 which is return value for John.
However when i select John. It disables P1_App upon clicking. But remains disabled even when i choose Andy.
This works for me using the following configuration.
Create form and report on EMP - everyone has access to that sample data, it is a good idea to post questions based on that.
In the form P3_DEPTNO is a select list with source
SELECT d.dname, d.deptno FROM dept d
Add a page item to my form P3_APP. This is a select list with "Allow multi selection" enabled. Select list has 2 static values.
Create a dynamic action on change of P3_DEPTNO.
Client side condition: Item = Value
Item: P3_DEPTNO
Value: 30 (note that this is the return value for SALES, not display value)
add true action of "Disable", affected item P3_APP
Click true action and select "Create Opposite Action". Save.
When I run this it work. Selecting SALES in the select list disables the item P3_APP and selecting something else enables it.

Reselect item on Select2 multi-value select list

I use plugin Select2 on Apex.
I have scenario like this:
I have three tables: ROOM, MASTER_STUDENT and MAP_STUDENT_ROOM
One ROOM can have many STUDENT
User can select more than one student(with Select2 from MASTER_STUDENT) when create ROOM
When user edit ROOM, previously selected student show in Select2 item(selected item by MAP_STUDENT_ROOM), so user can remove or add more Student
How to achieve point number 4, item Select2 list of values is MASTER_STUDENT but with default selected by MAP_STUDENT_ROOM?
I found this documentation, but i dont know how to apply it.
I'm not familiar with the Select2 plug-in.
Have you considered using the built-in Popup LOV, which since APEX 19.1 now allows multiple selection.
Whether you're using the Select2 plug-in or the built-in Popup LOV, the issue will be the same. You have a form on ROOM, that's trying to take into account an item that isn't part of the ROOM table (its values are stored in MAP_STUDENT_ROOM). The trick is to populate the item correctly during page load so that the item can correctly display the currently assigned students.
How is the item's Source configured? If it's not, set Type to SQL Query (return colon separated value). Assuming you have a primary key item on the page for the room (e.g. P1_ID), enter a query like the following:
select student_id
from MAP_STUDENT_ROOM
where room_id = :P1_ID
Then set Used to Always, replacing any existing value in session state.
This should get the item to display correctly when the page loads. However, you'll still have to figure out how to map the values back to the MAP_STUDENT_ROOM table correctly when the page is submitted. You'll need to add some logic that first deletes rows from the room (P1_ID) that are not in the selection (e.g. P1_ASSIGNED_STUDENTS). You can use APEX_STRING.SPLIT_NUMBERS to help:
delete from map_student_room
where room_id = :P1_ID
and student_id not in (
select column_value
from apex_string.split_number(:P1_ASSIGNED_STUDENTS, ':')
)
Then you can insert rows that are in the selection but not already in the room.
insert into map_student_room (
room_id,
student_id
)
select :P1_ID,
column_value
from apex_string.split_number(:P1_ASSIGNED_STUDENTS, ':')
where column_value not in (
select student_id
from map_student_room
where room_id = :P1_ID
)
I've not tested any of this code, but it should get the points across.
Another option would be to use an Interactive Grid instead of a list of values item. This is a classic master/detail scenario where students could be added and removed below the form region (typically only done after create).

Refresh Apex 5.0 chart results with different dynamic actions on same SQL query

I have created a bar chart on APEX 5.0 where my query looks like below:
select col1 as label,col2 as value from table1 where :P3_NEW_1 = col3;
here: P3_NEW_1 the page item I have created of type "Select List".
The list of values in "Select List" page item are pre-populated in the dropdown using the "Shared component" type I have created and so far this worked fine and I am able to display the results of above query by passing the value through the page item select list.
Now I need to add 2 data pickers on the same Apex page such that I should now be able to filter the results using date picker through dynamic action.
I know that using an additional button I can create a dynamic action but my problem is how do I modify the above query such that following should happen.
During the page load, once I select a particular value from the "Select List", it should display records based on the value selected from dropdown
This I already achieved using above sql query for the bar chart.
Once the bar char is displayed, I should next be able to filter and display the results using date ranges through date pickers.
Here my problem is my bar chart query is same but I need to now pass the start_date and end_date to the same above sql query which but I am not sure how to achieve this. If I add a button for dynamic action I need to select the report region which is the "bar chart" region and here my query needs modification.
Once the bar chart display the results, at the next step how do I filter the results by having the date filters with dynamic action on the same region where bar chart was displayed. How to achieve this?
You can change the query to something like this:
SELECT COL1 AS LABEL,
COL2 AS VALUE
FROM TABLE1
WHERE :P3_NEW_1 = COL3
AND (:P3_START_DATE IS NULL
OR TO_DATE(TIME_STAMP,'YYYY-MM-DD-HH24:MI:SS') BETWEEN :P3_START_DATE AND NVL(:P3_END_DATE,SYSDATE));
Where :P3_Start_date and :P3_End_date are the Start and End date pickers and TIME_STAMP is your column where you store the date.
After modifying the query you can simply add a button where at Behavior>Action select Submit Page.
This way when you click the button, the page will be submitted and chart refreshed.
If you want to take your chart to the next level you can do a partial refresh on it. Here is a short video tutorial of partial refresh on a report but you can apply the same login on your chart.
