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.
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 am using APEX 21.1. I am building a clinic management system. I have an interactive report based on a join between two tables SELECT e.id examination_id,E.DIAGNOSIS,dbms_lob.getlength(a.img) img, a.id,attachment_id FROM examination e JOIN examination_attachment a ON A.EXAMINATION_ID = e.id. The examination could have many attachments. This is the result of the query.
I changed IMG column's type to Display Image. When it asks for BLOB ATTRIBUTES, I set table name to examination_attachment. That's the table that have the images. And I enter the primary key as the table's PK(id). The page displays error No data found. The SQL query returns that id duplicated when there is more than one row in the examination_attachment table. I think that's the reason behind the error but not sure. I created a view with the same select statement without the dbms_lob.... part. Just selected the IMG column. And in BLOB attributes, I set the table to the view name, and the primary key as the attachment_id because it's the column that's not duplicated. And it worked. But I need to get it to work without views and I need to know if the cause of the error is right?
I am using "Picnet Table filter" for filtering my tables.
I am using display tag for displaying my table data.
I have hnadreds of records to show in the table and hence I have used pagination where page size is 50.
I am showing 50 records per page.
When I use this plugin to filter the data in the table, it only filters data on the current page.
Is there any way we can make "Picnet Table filter" to filter the data on the entire list rather than in just the page?
Please help.
Thanks
