My Scenario:
I have a report on page 1 which has a link to page 2. This link passes an ID to page 2 (V2_ID gets set with V1_ID).
I then have two items called V2_ID and V2_NAME on page 2, as well as a PL/SQL process on page 2 which executes after the header loads which
select name into :V2_NAME from table where id = :V_ID;
The V2_ID shows the value, but the V2_NAME is always blank.
How can I pre-populate this variable. This is a very simple example as my use case is much more complicated, but the concept is the same. I can't use automatic row fetch because each item comes from a different table (it is a horrible database design, but I have to work with it).
Cheers
If on page 2 you have a PL/SQL process at the process point='On Load - After Header' and the procedure looks something like this:
Begin
select name into :V2_NAME from table where id =:V2_ID;
end;
and no condition on it then it should work.
Check that :V2_NAME does not have Source Type= Always NULL;
Correct me if Im wrong, from what ive understood, only one value is passed from page 1 to page 2 which is V1_ID to V2_ID,right?then on page 2, you have a process that will execute after the header loads and that is
SELECT name
INTO :V2_NAME
FROM TABLE
WHERE id = :V_ID
Is the :V_ID a typo?It should be :V2_ID,if its not maybe its the cause as to why :V2_NAME doesnt give you a value.
Instead of having a process after header, why dont you just put the query in the item SOURCE, choose type: QUERY, used: ALWAYS, REPLACE ANY EXISTING VALUES ON SESSION STATE.
then in the query box, put
SELECT name
FROM TABLE
WHERE id = :V2_ID

The same question once again but with (I hope) better explanation:
I created the most simple case:
An Interactive Grid IG with data source EMP ( table with 14 records contains Ename, Job, HireDate, Salary etc. etc.)
Text field P7_ENAME
After running it looks like below:
What I would like to do is to copy Ename from selected record of IG to P7_ENAME field .
I found several tutorials (text and video) how to do it. Most of them suggest to create dynamic action SelectionChange on IG and when TRUE add a JavaScript code something like below:
var v_ename;
model = this.data.model;
v_ename = model.getValue( this.data.selectedRecords[0], "Ename");
apex.item( "P7_ENAME" ).setValue (v_ename);
and the second step is to create another action: Refresh.
So finally I have a dynamic action with two steps : the first one is a Java script code and the second refresh function on my P7_ENAME field.
Sounds simple and it is simple to repeat/implement. A guy (I suppose) from India published a video on YouTube (https://www.youtube.com/watch?v=XuFz885Yndw) which I followed and in his case it works good. In my case it simple does not work - field P7ENAME is always empty, no errors appears. Any idea why ? Any hints, suggestion ?
thanks for any help

The best way to debug and achieve what you are trying to do is as follows:
create the Dynamic action with the following setup:
-when -> selection change[interactive grid],
-selection type -> region, region -> your IG region,
-client side condition -> javascript expression: ```this.data.selectedRecords[0] != undefined```
First action of the true of the DA with the type: execute javascript code and fire on initialization is turned on, code: console.log(this.data.selectedRecords);
Run your page, and check the browser console. You should see an array of columns when you select a record from that IG as follows:
Find in that array, which sort number of the array contains the data that you want to use for the page item. Let's say I want the 3rd element which is "2694" then I should change my dynamic action's execute javascript code to:
var value = this.data.selectedRecords[0][2];
apex.item( "P7_ENAME" ).setValue (value);
The last thing I should do is add another true action (and the refresh action at the end) to the same dynamic action with type 'SET VALUE' and 'PLSQL EXPRESSION' as type, put :P7_ENAME in the expression, items to submit P7_ENAME and affected element: item / P7_ENAME as follows:
I have a Master Detial with 2 interactive grids.
I would like to be able to genrate a link based on user input....is that at all possible?
To give a simple example:
Lets say I have website like https://www.google.com/
I would like a user to enter anything...for example "Prague"
Once this is entered, I would like APEX to generate a URL from it to result in: https://www.google.com/Prague
Now I know that Google search does not work like that, but I need that sort of mechanism for our internal company app. Is this possible?
Ideally , once the grid is saved the link in the Interactive grid only said "Prague" but if I click it, it would direct me to https://www.google.com/Prague
This can be achieved using the "JavaScript Initialization Code" attribute of the column.
Example on the EMP sample table (*). Functionality is that when a user enters a value in the ENAME column, it is converted to a google search url.
Create an editable IG on table EMP
Set the type of column ENAME to "Text Field"
Set "Javascript Initialization Code" for column "ENAME" to
function(config) {
config.defaultGridColumnOptions = {
cellTemplate: '&ENAME.'
};
return config;
}
Notice that the column now is a link. A user will have to open in new window to get the actual link value, since clicking the column will active the edit mode.
(*) Sample dataset can be installed using SQL Workshop > UTILITIES > Sample Data Sets > EMP/DEPT
yes, you can let user enter the value and by creating a dynamic action(choose the when attribute as whatever suits you) you can take that value and on another column, use that column as &Columnvalue. for example and concatanate it by using to base url using ||
How can I overcome this {Ajax call returned server error ORA-01403: no data found for} problem? Problem arises ,When I want to set Order_Status_Field value 2 in IG where query was Order_Status_Id=1.
My IG query was :
SELECT P.ORDER_ID, P.ORDER_STATUS_ID FROM ORDER_DETAILS P WHERE P.ORDER_STATUS_ID=1;
My Workspace Name: ZISHAN
User: ZISHANIIUC#GMAIL.COM
Pass: 123
Problem Page No: 3 (Order Report)
1. Before Updating Order Status:
2. After Updating Order Status:
I saw your are using standard "Interactive Grid - Automatic Row Processing (DML)" process, which is an AJAX approach. this apex behaviour is a call ajax using json format for data. so you have a filter on your sql query
SELECT T.ORDER_ID,
T.TABLE_ID,
T.TAKEN_BY,
T.ORDER_STATUS_ID,
T.TOTAL_COST
FROM ORDER_DETAILS T
WHERE T.ORDER_STATUS_ID=2
and you want to update your filter column (data has change) it's seem like apex do not find the prevouis data filter and return no_data_found (not really sure what happen ) but for solution : .
put your filter in interactive grid --> action button ---> filter
or
write your own custom process
When i tried do alter the process from the "Interactive Grid - Automatic Row Processing (DML)" that apex creats, for my own custom PL/SQL Code i needed to choose one of the columns from the query to be the primary key, and then i could use the pl/sql custom process as found here on this blog:
https://mikesmithers.wordpress.com/2019/07/23/customizing-dml-in-an-apex-interactive-grid/ without the no data found error.
I have an interactive report and a form associated to it. After creating a new entry using the form, my end-users want to put the focus on that specific new entry in the interactive report (it's a lot of entrys, and today they need to scroll down a lot to see the new one).
They also want the same funcionality when updating a row of the report.
How can I do this the correct way in APEX 5.1?
Here is one aproach based on EMP table in apex.oracle.com Create interactive report with edit form. In my case this is page 6 for report and page 7 for edit. Create one hiden item on page six (P6_EMPNO). Add case to your query so in my example it's look something like:
select "ROWID",
"EMPNO",
"ENAME",
"JOB",
"MGR",
"HIREDATE",
"SAL",
"COMM",
"DEPTNO"
from "#OWNER#"."EMP"
ORDER BY CASE WHEN EMPNO = :P6_EMPNO THEN 1 ELSE 2 END, EMPNO
I'm sorting result by EMPNO.
Choose P6_EMPNO in Page Items to Submit section. Go to page 7, select branch(Go to page 6)and click on Target In set items section choose P6_EMPNO and for target &P7_EMPNO.
Now every time you go to page 7, the value of hiden item will be the EMPNO from page 7 and it will apear on top of the region. You can use jQuery to highlight the row and put some validations to update P6_EMPNO only when some data was changed.
I hope this can help you.
easy.
You don't even have to create any additional page items. Change your form DML so that it returns into the primary key page item holder. Then Create a process after your DML process but before the reset cache process. Use APEX_IR API to reset pagination on your IR page, and then set an interactive report filter based on the primary key page item you returned the new PK into. Check the documentation for exact usage.
Apex_IR.reset_report to reset the report pagination and remove any filters.
Apex_ir.add_filter to add a filter = to new primary key
Interesting question, another solution:
Create a item in your report page, something like P3_ANCHOR
Add data-anchor="#< YOUR_COLUMN_ID >#" to your report link attribute
Configure your form page to return the created/modified item id to item P3_ANCHOR in your report page.
Create a Dynamic Action on report page
Action: Execute Javascript Code
Code:
var container = $('body'),
scrollTo = $('[data-anchor="'+$v('P3_ANCHOR')+'"]');
container.animate({
scrollTop: scrollTo.offset().top - $(document).scrollTop()
}, 2000);
Simple solution:
Sort your report descending so that the last created ID will be the first in the IR
This is a very odd question but i wondered whether it was possible to trigger a process that runs an SQL UPDATE when the user leaves this specific page, either by clicking on the breadcrumb, tabs or back button?
I did setup the process to run on the 'Back' button; however i ran into the problem of: What if s/he clicks on the breadcrumb or a tab instead.
I have searched the net and posting this question was a last resort. I wondered if anyone can point me in the correct direction?
UPDATED POST
Page 1:
Includes a text field and a button. The user enters the category into the text field and clicks on the button to proceed to the next page. The button passes the value in the text field to a text field on Page 2.
Page 2:
Two regions on the page. One region holds information about the category - Category name from the previous page, category description, and the category revision number (which is what i'm trying to get working). The second region is a report that pulls the item name and number that are listed under the category in the category text field. A 'View' link is used on the report to load the edit page for the specific item selected. The 'View' link passes the 'category name' (from the category text field) and the 'item number' from the report to page 3.
Page 3
Two regions are used, first region: Lists the Item number which came from page 2 and name of the item (which i use a simple query to retrieve). In the second region: A report is used with two columns: a list of item properties in column 1, and a text field next to each item property in column 2 to hold the value that can be updated. The 'Apply Changes' button has some PlSql behind which looks for changes and updates where required. It updates the relevant fields that have changed, and it then takes the user back to Page 2 (Page showing user the items listed for the category intitally entered).
I cant increase the category revision on the 'apply changes' button on page 3 because the user may complete edits for items under the same category. So i dont know where i can increase the category revision by 1 per vist to a category. P.s I already increment the revision number for each item by 1 if the info has been changed using the 'apply changes' button on page 3.
One way of doing this is by updating the session state of the page items (without submitting the page as normal) via ajax and by calling an Application Process which updates the table, when called by a javascript onbeforeunload.
Create an Application Process to fire On Demand, named UpdatePageXOnExit or something. In the PL/SQL block of that Application Process, use SQL update commands with the item state of each item on the page that you wish to update; something like the following:
BEGIN
UPDATE table_name SET col1 = :PX_ITEM_1, col2 = :PX_ITEM_2, col3 = :PX_ITEM3, col4 = :PX_ITEM_4, col5 = PX_ITEM_5
WHERE (condition... I would suggest ROWIDs to simplify changes to the
fields of the PK; otherwise you will have to create additional
page items for each field of the PK, then set those items to
the values of the PK when the page loads using a before
header page process, and then use those values in this where
clause like this: where col1 = :PX_ORIGINAL_PK_FIELD_1 AND col2 =
:PX_ORIGINAL_PK_FIELD_2 );
END ;
Go to the page settings for that particular page, and in the JavaScript: Execute On Page Load section, write something like the following:
window.onbeforeunload = updateOnExit;
And in the JavaScript Function and Global Variables Declaration, write something like the following:
function updateOnExit() {
var get = new htmldb_Get(null,&APP_ID.,'APPLICATION_PROCESS=UpdatePageXOnExit',&APP_PAGE_ID.);
get.add('PX_ITEM_1',$x('PX_ITEM_1').value)
get.add('PX_ITEM_2',$x('PX_ITEM_2').value)
get.add('PX_ITEM_3',$x('PX_ITEM_3').value)
get.add('PX_ITEM_4',$x('PX_ITEM_4').value)
get.add('PX_ITEM_5',$x('PX_ITEM_5').value)
gReturn = get.get();
get = null;
// Comment out the following line or not, as per the note in the following paragraph
return 'Are you sure you would like to leave the page?';
}
This last piece is the AJAX that updates the session states of the page items on the page that have been changed on the user's end but that haven't been uploaded to the servers end which normally occurs during page submission. Note: If you comment out the return statement, than there will be no warning box that will allow the user to stay on the page. If that is what you prefer, go for it. If you chose to use the warning box, the ajax will execute the page process even if the user chooses to stay on the page.
