I have an Interactive Report. The Interactive Report is in a form. There are images and other columns, like the ID, in the Report. How can I get the ID of the selected Row and store it in a Page Item?
This is an example based on the "emp" table in the emp/dept dataset. Functionality: when user clicks on an employee name, the empno of that user is set in page item P44_ITEM.
IR source:
select EMPNO,
ENAME,
JOB,
MGR,
HIREDATE,
SAL,
COMM,
DEPTNO
from EMP
There is a page item P44_ITEM that should be set to the EMPNO when the column ename is clicked in the report.
In the report, set the attribute "Column Formatting > HTML Expression" for the column "ENAME" to value <div class="sel-ename" data-empno="#EMPNO#">#ENAME#</div>. Explanation: wrap a div around the text, and add a class "sel-ename" to the cell and a "data-" attribute containing the empno value for the current row.
Create a dynamic action:
Event: Click
Selection Type: jQuery Selector
jQuery Selector: .sel-ename
Create a true action for the dynamic action
Action: Set Value
Set Type: javascript Expression
this.triggeringElement.dataset['empno']
Affected element P44_ITEM
Save and run.

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.
I understand that the default behavior of LOVs is the following:
SELECT business_desc as display_val,
business_id as return_val
FROM businesses
This attached to a select type page item P1_BUSINESS will display a list and when a list row is selected, then assign the business_id value to the page item P1_BUSINESS.
Is there a way to build a list of values to set the value of more than one page item that are not displayed? Using the below SQL:
SELECT business_desc as display_val,
business_id as return_val,
form_type,
individual_flag
FROM businesses
Where now when a user selects something from P1_BUSINESS it sets the values of that row/record as follows:
P1_BUSINESS = business_id (like it does by default)
P1_FORM_TYPE = form_type (P1_FORM_TYPE is a hidden page item)
P1_IND_FLAG = individual_flag (P1_IND_FLAG is a hidden page item)
I know I can do this with an onchange dynamic action, but just curious if can do inside the LOV or select page item (P1_BUSINESS) declaratively.
In Shared Components > List Of Values, there is an attribute "Additional Display Columns". The help text on that screen says it all Additional display columns can be defined for item types that support multiple display columns, for example the Popup LOV. For item types that do not support multiple columns, these will be ignored. If adding additional display columns ensure that the return column is included in the column list. The return column can be set to Visible No and Searchable No if you do not want it displayed to users.
Example using emp/dept sample data:
Create a list of values on table emp with return empno and display ename. Save.
Edit the LOV and click Additional Display Columns > Select Columns. Select job as additional column.
In the IG, set Visible and Searchable to "No" and Apply Changes.
On the page, create 2 page items: P1_EMPNO (type popup LOV) and P1_JOB (type Text Field)
For P1_EMPNO, pick the LOV created above as shared component > List Of Values and add JOB:P2_JOB under Settings > Additional Output. JOB is the additional column name/alias and P2_JOB is the item it should map to.
Now when you run the page, observe that P1_JOB is populated when you select a value for P1_EMPNO
I'm learning APEX 5
I have a control named X_CONTROL, where I want to populate his content with an SQL query.
To do that, I need the ID primary key from a table, which should be the ID of the row selected on a Select List control named MY_LIST_CONTROL.
MY_LIST_CONTROL has a list of values taken from a column of the table "MyTable", which is not the ID primary key.
I tried to populate X_CONTROL with this SQL
Select ID from MyTable where ColumnName=:MY_LIST_CONTROL
It doesn't work, and should not work because ColumnName is not "unique", like ID is.
So, the question is, how do I recover, with SQL, the ID of the selected row which correspond to the selected value in MY_LIST_CONTROL.
It should be SQL, because APEX 5 demands an SQL query to populate the X_CONTROL.
I have set up a simple example here on apex.oracle.com:
Whenever a Department is selected (item P32_DEPTNO), its Location is copied into the second item (P32_LOC).
This is done by a dynamic action on P32_DEPTNO defined as follows:
Event: Change
Selection Type: Item(s)
Item(s): P32_DEPTNO
TRUE Action:
Action: Set Value
Set Type: SQL Statement
SQL Statement:
select loc
from dept
where deptno = :P32_DEPTNO
Items to Submit: P32_DEPTNO
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.
I'm using Oracle Apex 4.2. I have a select list and a text field. I'm trying to create a dynamic action that should be simple enough but I'm not sure how to do it. Basically depending on what value the user selects from the list of values in the select list, the text field should then be populated. So for example:
Let's say the select list gives the user the choice to select 'Animal', 'Car', 'Person'. If the user selects 'Animal' then the text field should immediately have the value 'cat'. If the user selects 'Car' then the text field should immediately have the value 'toyota'. If the user selects 'Person# then the text field should immediately have the value 'jim' etc.
How would I make this dynamic action?
Thanks,
Stephen.
Create a New Dynamic Action with the following properties
Main Properties
Event: Change
Selection Type: Item
Item(s): [Select List]
Condition: No Condition
True Action
Action: Execute PL/SQL code
Fire When event Result is: True
PL/SQL Code:
Option 1 - use a lookup table
select LOOKUP_VALUE
into :P1_TEXT
from LOOKUP_TABLE
where original_value = :P1_SELECT_LIST;
Option 2 - Use hardcoded values
CASE upper(:P1_SELECT_LIST)
WHEN 'ANIMAL' THEN :P1_TEXT := 'cat';
WHEN 'CAR' THEN :P1_TEXT := 'toyota';
WHEN 'PERSON' THEN :P1_TEXT := 'jim';
ELSE :P1_TEXT := null;
END CASE;
Page Items to Submit: [P1_SELECT_LIST]
Page Items to Return [P1_TEXT]
