I am building a student module application in Oracle Apex 5.0 and wanted to know how to display the details in oracle apex.
Something like this with two tabs on the 1 page:
on first tab, When input StudentID,
the first section will contain system_date and tutor name that has login
second section should contain student name and course desc & course year
third section is to display current semester module, if payment done or not (Y /N), markings %, date of payment.
2nd tab of the page to include all courses done for that student.
Which layout to choose (interactive grid/report) or any other.
How to add validation of date picker for the payment date so that upon input it insert directly in table in DD-MON-YY format and also that it takes system_date??
Note table:
student_details: the student name, address and personal details
course_detail table contains the courses for the semester
payment_detail table for the payment details
The sort of things you're going to want to look for are:
Region Display selector, for multiple tabs
Any type of report region to display data, and you can have multiple, and nest them as sub-regions.
You can define page items that are displayed as date pickers, and use default values to source today's date using the keyword SYSDATE.
You're going to need to understand SQL.

I have a table ORDERS which contains column ORDER_DATE. I have created a Chart as a Bar type. I want the chart to show the amount of orders in a given date or range.
I'm following this Youtube tutorial which shows how to create a datepicker that returns a range in a Report. I'm trying to replicate this in a chart.
What I've done so far
Created datepicker items P5_DATE_FROM and P5_DATE_TO
Changed the Series Source Type to SQL Query
select ORDER_ID,
ORDER_NUMBER,
TO_CHAR(ORDER_DATE, 'YYYY-MM-DD') AS ORDERDATE,
STORE_ID,
FULL_NAME,
EMAIL,
CITY,
STATE,
ZIP_CODE,
CREDIT_CARD,
ORDER_ITEMS,
APEX$SYNC_STEP_STATIC_ID,
APEX$ROW_SYNC_TIMESTAMP
from ORDERS_LOCAL
where TO_CHAR(ORDER_DATE, 'YYYY-MM-DD') between :P5_DATE_FROM and :P5_DATE_TO
Source Page Items to Submit added P5_DATE_FROM,P5_DATE_TO
I basically followed the exact steps of the video. However, since the video is for a report and mine is for a chart, the chart isn't actually returning any data.
I think this is because for charts there are additional fields I need to configure. I noticed the video didn't cover Column Mapping and I'm a bit confused to what to enter here.
----------------UPDATE-------------
I've followed Koen's instructions from his answer. It seems like to TO_CHAR function was causing the error. I've updated the SQL Query to below:
select ORDER_ID,
ORDER_NUMBER,
ORDER_DATE,
STORE_ID,
FULL_NAME,
EMAIL,
CITY,
STATE,
ZIP_CODE,
CREDIT_CARD,
ORDER_ITEMS,
APEX$SYNC_STEP_STATIC_ID,
APEX$ROW_SYNC_TIMESTAMP
from ORDERS_LOCAL
where ORDER_DATE between TO_DATE(:P5_DATE_FROM,'YYYY-MM-DD') and TO_DATE(:P5_DATE_TO,'YYYY-MM-DD')
However, on the Page Designer I cannot save and run page until I select Column Mapping - Label and Value. I've set the Label as ORDER_DATE but I am unsure of what to select for the Value.
Setting the Value to ORDER_DATE shows an error Ajax call returned server error ORA-01403: no data found for CHART Count Orders by Date.
and selecting any other Value such as ORDER_NUMBER or ZIP_CODE populates the chart with the actual integer value of the column (ex: ZIP_CODE returns a chart of x-axis: date, y-axis: actual zip code numbers)
I see 2 possible issues.
You submit P5_DATE_FROM and P5_DATE_TO but the source has P1_DATE_FROM and P1_DATE_TO - not sure that is a typo but it should all be the same...
The where clause is wrong. This
from ORDERS_LOCAL
where TO_CHAR(ORDER_DATE, 'MM-DD-YYYY') between :P1_DATE_FROM and :P1_DATE_TO
should be
from ORDERS_LOCAL
where ORDER_DATE between TO_DATE(:P1_DATE_FROM,'MM-DD-YYYY') and TO_DATE(:P1_DATE_TO,'MM-DD-YYYY')
Reason: the column orders_local.order_date is of datatype DATE. If you convert it to a string using TO_CHAR then it will be a string comparison, not a date comparison.
Note that bind variables P1_DATE_FROM and P1_DATE_TO are strings - they're defined in the DOM on the html page and that has no concept of oracle datatypes so everything is just a string. If they're used as such in a date comparison, you're relying on implicit conversion by the database. It's safer to do explicit conversion using the TO_DATE function.
--UPDATE--
Your question starts with "I want the chart to show the amount of orders in a given date or range.". Well... there is your answer. The "Value" is the amount of orders on each day. Update your source query to include a count of the orders and group by day. Then make your value attribute the column that has the count.
I am trying to take the filter context from my PBI dashboard to a Power App Edit Form. The scenario is as follows:
I have two tables:
Comments_Table:(empty until write back data is submitted)
Salesperson
Comments
Date
Value
Salesperson_Table:
Salesperson
Information
Salesperson1
1
Salesperson2
2
The Power App should allow users to Write Back data for the following columns to the Comments_Table:
Comments (free text)
Date (date)
Value (free text)
Every new entry should be a new row in the table.
The selected Salesperson should also be written back but should be set by the users' selection in a PBI filter. For instance, in the dashboard, users will be forced to select a unique salesperson, and this should filter the Power App.
I currently have two issues. I have set up a Form that makes a LookUp on a gallery which references the Salesperson table via the PowerBIIntegration.Data. Salesperson is in the form as a view text only item.
I am only able to filter to values that already exist in the Comments table (I prefilled some dummy rows) - it does not currently take the value from the Salesperson table...
Every new entry in the Edit Data Form overwrites the previous entry
for that salesperson. It should add a new of data instead...
Any ideas on how to proceed would be greatly appreciated...
I need to change the inventory category for a couple of account numbers and only for a couple of companies. The inventory category for these accounts are mapped based on the account number but need to be changed specifically just for two companies. I've tried to filter by the company number and then find/replace, which worked fine, but then I can't unfilter to bring back the rest of the companies. I can't change the category for just those account numbers because it is only different for just those two companies.
Lisa, Here's perhaps a simpler approach than where your current way is taking you.
If I begin with this table:
Then I add a column (Add Column -> Custom Column) with the following:
The formula uses an if statement to determine whether each row has a specific Account (Acct. 4) AND Company (Co. 8). If so, then 99 is returned as a new category value for that row of the new column. If not, then the original Inventory Category is returned as a value for that row of the new column. (Obviously, you would edit this formula accordingly, to support your account, company, and new inventory category values.)
Here's the result:
Then I could delete the original Inventory Category column and rename the remaining New Inventory Category column to Inventory Category.
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).
I have a date field and a interactive grid. I am trying to generate the Interactive grid based on the value inputted in the date field.
I am trying to write the query as below :
select pap.effective_start_date , pap.effective_end_date
from per_all_people_f pap
where :SELECT_DATE between pap.effective_start_date and
pap.effective_end_date
Here, SELECT_DATE is the name of the Date field (datatype Date picker). I am writing a dynamic action on Change of Date field, and refreshing the interactive grid region.
But when I change the value in Date field, it doesn't return any rows.
I have done a similar change where my interactive grid was based on a dropdown. There I had to set the "page action on selection" to Submit, and it worked. But here, since it is a Date field, the "Page Action on selection" property doesn't appear on the page .
Can somebody please suggest, how can I achieve this.
You need to explicitly convert your bind variables, which are treated as strings, to dates.
to_date(:SELECT_DATE)
The format mask will come from the application properties, or you can be explicit with that, too.
