I have created a LOV on oaf page. The issue is when i select any row from LOV page, it's reloading the (lov) page instead returning the values to back page.
If we keeps opened LOV window for more than 5 minutes and then select any row, it works.
Thanks in advance
In OAF, while creating an LOV, i.e., messageLOVInput item, lovMap is required to be set.
Make sure the LOV Region Item, Return Item and Criteria Item in this lovMap is set properly.
LOV Region Item : field from which value is picked from lov table
Return Item : field in which value should be set on selection from list of values
Criteria Item : field which is validated for value

I have a dropdown to select no. of rows displayed in dash.datatable (eg. 4 rows default)
But when changed row no. is changed in dropdown my table values are gone.
I want them unchanged when increase the row value. can someone help me on this.
Callback used to fetch the row in datatable is here
#app.callback(
Output('data_table','data'), Input('dropdown','value'),
)
def table(rows):
if rows is not None:
return dbdata.head(rows).to_dict('records')
I don't want to include any button to add new row, just when the dropwdown is changed I want the table value to remain unchanged.
I would like to update all rows inside one column. Each column would have its own input which will update the rest of the rows. Currently I have an existing edit batch table. I was wondeing if it was possible to:
select a column (maybe with checkbox)
Row 1 is empty, however will trigger a function
This function takes the input value (which the user will type) of row 1 cell and populate this value for every row inside the that column.
COL 1 || COL 2
row 1 || row 1
row Z || row Z
After this the user should still be able to activate the cancel button and the original data appears back in the table. The table data should not be saved unless the saved button is pressed.
I've tried a fucntion using a button where we would execute row.set(column, value), however this would refresh the grid table and the original data would reappear.
I am trying to make a cost value populate in an interactive grid column based on the value selected in an Item column.
My setup is:
An "Item" table which contains a list of Items, and the "Cost" assigned to the item.
A "Quote" table which contains general info about the quote, i.e. company name, date created, signed, signed date etc.
A "Quote_Items" table which assigns an Item to a quote by Quote_ID, and Item_ID. I added a Cost column to the Quote Items table to be able to see it in the interactive grid, and update it.
For the Quote Items I created an Interactive grid to add Items to the quote.
I set the Item_ID column in my interactive grid to a popup LOV which populates the Item_ID based on the selected item.
To populate the "Quote_Item.Cost" I added a dynamic action to the Item_ID column to:
Event:Change
selection Type: Column(s)
Region: ..Item List
Column(s): Item_ID
Action: Set Value
Set Type: SQL Statement
SQL Statement: SELECT I.COST
FROM WIP_ITEMS I
WHERE I.ITEM_ID = ITEM_ID
Items to Submit: COST
The result is, when I select an Item from the dropdown, all values in the "Items.Cost" table are displayed in comma separated values in the field:
Quote Item populating all item costs in one field
It seems like the "WHERE I.ITEM_ID = ITEM_ID" part of the SQL query is not working correctly? How can I get it to show only the Value associated with the Item_ID?
Syntax to reference a column in the SQL query > :COLUMN_NAME
So your SQL query should looks like this:
SELECT i.cost
FROM wip_items i
WHERE i.item_id = :ITEM_ID
And you need to modify the "Items to Submit" parameter too, because it must always be the value which your reference in the where condition, so in your case it should be:
Items to Submit: ITEM_ID
I'm new to Oracle Forms Builder and I want to display only the max Value of a column. How can I do this?
I presume
You created a Data Block(let's call emp) which has a Query Data Source Name (assume
Oracle's famous emp table)
with Multiple Records Displayed,
and of type Tabular.
Add a max_empno to the Data Block emp, under the item empno
with Number of Items Displayed property set to 1,
Database Item property set to No,
Calculation Mode property set to Summary,
Summary Function property set to Max,
Summarized Block is emp,
Summarized Item is empno.
and setting Query All Records property of the block emp to Yes
shouldn't be forgotten. Then, When the form module is run, the
following interface will appear :
I have an Apex page with a select list item populated from a SQL query that should default to the product of the item passed through from another page, however it always selects the first item in the list.
We need to set it so it selects the current category however I can't see where this setting is. The version of APEX is 3.2.
Firstly, I suspect (correct me if I'm wrong) that your item is selecting the first item because the item is defined with Display Null Value set to No; internally, however, the item is probably NULL, but the list item cannot show it so it just shows the first list value. But I probably wouldn't change this setting.
To set the default value for a Select List item, set Default Value Type to PL/SQL Function Body, then enter your SQL query (that returns a single value) in the Default attribute for the item, with suitable PL/SQL around it, e.g.:
DECLARE
v_value VARCHAR2(<your data max length>);
BEGIN
SELECT <yourcolumn>
INTO v_value
FROM <yourquery>;
RETURN v_value;
END;
