Application Express :: How To Validate In Common PL/SQL Package And Show Custom Messages
Feb 11, 2013
Currently if i let required field empty, then APEX puts systematic error message "XXX must have some value." near the field and into the page header. I want to create custom business rule, that would show message for example "This action cannot be performed, because this and that...".
That kind of custom validation should be in my plSql package and somehow it should throw/send the phrase "This action cannot be performed, because this and that..." to the page header where was message "XXX must have some value.".
How can i create such custom error message to appear out using PlSql package function that i define myself? I plan to create a common validation package, which has lots of plsql functions to validate lot of APEX pages/forms, all those functions should throw/send somehow error messages to page header. I looked that this unofficial solution does not suit for me:

Because it disables APEX systematic automatic validations as i understand, and is unofficial.
I am using custom authentication with APEX 4.1.1 and I want to display custom error messages on the login page if authentication fails. In my authentication function I'm using apex_util.set_authenication_result to set a result code (code below).
I've tried to use the apex_util.get_authentication_result on the login page to hide and show custom messages but it's not working. I don't believe the apex_util.get_authentication_result is actually obtaining the result?
FUNCTION verify_user( p_username VARCHAR2, p_password VARCHAR2 ) RETURN BOOLEAN IS v_ctr NUMBER; [code].........
I am trying to change the default behavior of Hide/Show Region to show, after some attempts i got it partially working but now clicking the icon to toggle hide/show doesn't work also changed the icons and added type="" but its not working.
I'm trying to translate all of the interactive report messages, on Apex 4.2. I'm using this [
[URL].........
As a reference. I have several problems translating the help section of the interactive report. First of all, I can't seem to find all of the message names. The ones I couldn't find were:
Sets the number of records to display per page.(regarding displaying certain number of rows per page)
Format enable you to customize the display of the report. Format contains the following sub menu:
Sort Control Break Highlight Compute Aggregate Chart Group By(regarding format)
You can define one Group By report per saved report. Once defined, you can switch between the group by and report views using links below the Search bar. To create a Group By report, you select:
the columns on which to group (up to 3 columns can be selected) the columns to aggregate along with the function to be performed (average, sum, count, etc.) the columns to use for sorting (up to 3 columns can be selected along with direction and null sorting options)(regarding group by)
And secondly, I have translated this message
Select columns icon enables you to identify which column to search (or all). Text area enables you to enter case insensitive search criteria (wild card characters are implied). Go button executes the search. Reports displays alternate default and saved private or public reports.
Actions Menu enables you to customize a report. See the sections that follow.using this message name:
APEXIR_HELP_SEARCH_BAR.
However, now I have two messages shown in that section: the original one, in English, and the translated one.
I'm trying to connect a javascript UI control within my page to an APEX Application Process. The control calls the application process via AJAX and appends a variable number of GET / POST parameters to its URL.What is the best way to obtain these parameters from within the PLSQL procedure of the process? Or is there a better way to connect my javascript AJAX control to the Database behind my APEX app?
Suppose, there is a package p1 with proc A, Proc B and Func C.Now when any of the package proc or func gets invoked from a stored proc G then a common code which reads the cols of table xyz should be executed. How to do that?
I need to rescue some valors from Excel, and then close the excel file without saving changes and without messages.
I am using THe DDE package and when using
DDE.EXECUTE(convid, '[Save()]', 10000);
there is no problem, but the changes are saved. I have tried '[Exit()]' and '[Close()]' but always have error message ORA-106555. Is there any way of doing this without errors?
use BI publisher to create custom report layouts, which are uploaded via APEX in the Shared components reports area.
The users wish to be able to select which report layout they want to use on the fly, e.g. select from drop down list which I'd hope to dynamically populate without having to hard code the report layout names into it.
From what I can find, it’s been stated that the layout names etc are stored in wwv_flow_files. However when I look here, I see all “history” of the files, even report layouts that were created and then subsequently deleted.
how, I can retrieve the details on exactly what report layouts are “active”?
I have created a custom download procedure to download uploaded files from custom table records which are displayed via links and i call my procedure as #OWNER#.my_file?p_file=#ID#. Now the problem this procedure call works in my development system not any other system.
is there any grant i need to provide but i don't want to grant to public also apex 4.1.1 create or replace PROCEDURE
my_file(p_file in number) AS v_mime VARCHAR2(500); v_length NUMBER; v_file_name VARCHAR2(400); Lob_loc BLOB;BEGIN SELECT trim(MIME_TYPE), BLOB_CONTENT, trim(filename),DBMS_LOB.GETLENGTH(blob_content) INTO v_mime,lob_loc,v_file_name,v_length FROM EMP.FILE_attachments WHERE id = p_file; owa_util.mime_header( nvl(v_mime,'application/octet'), FALSE ); htp.p('Content-length: ' || v_length); htp.p('Content-Disposition: attachment; filename="'||replace(replace(substr(v_file_name,instr(v_file_name,'/')+1),chr(10),null),chr(13),null)|| '"'); owa_util.http_header_close; wpg_docload.download_file( Lob_loc ); ---------------------------------
I am having report region with different columns, in that one column heading needs to be start with lower case like "iST Status" but always it is showing "IST Status".
I have an application which contains a chart of type Dial.In order to set the major interval dynamically I have switched to using custom xml and replaced the #SCALE_DATA# with:
However, I would also like to label the value with a Units Label (e.g. '%'). I was previously doing this using the Value: Postfix setting under Axes Settings, but after switching to Custom Settings removes this box and I no longer get the units displayed.
Is there some xml I can add which will set and display the units.I am using Application Express 4.0.2.00.09
I have a region where I have 3 textfields and a Submit button. Then, another report region where I have a query with the where condition that makes reference to the 3 texfields. This is:
Select * from ANYTABLE where column1 = :P1_TEXTFIELD1 and column2 = :P1_TEXTFIELD2 and column3 = :P1_TEXTFIELD3
When I click the submit button, the report is reloaded (in fact, all the page) with all the conditions (in textfields) correctly. Now, what I need is that when I click the submit button, the filter appears in the screen; I mean, show the funnel with the filter conditions as if I made it since the search bar.
Apex 3.2 I have a field called P14_START_DATE.The display as type is Date Picker (DD.MM.YYYY). Now if the user uses the pop up calendar, the field is populated with eg 07.12.2013. I have 2 standard validations, not null and item specified is a valid date. If the user decides to type in the date, they can use a different format, eg 07/12/2013, which I do not want to happen.How can I validate the field, so they get an error if they do not use format dd.mm.yyyy.
Our application has a homepage that displays results of several SQL statements that are defined as reports. One report in particular should only display a custom message when Count of Invoices having a particular status > 0, and not the actual invoice count itself.
I have gotten the layout to not display the count but I need to be able to display a custom message that says "Problem Invoices exist. Please see Invoices Report for more information." I've looked over the Report Attributes definition page but I cannot find how to display this custom message.
1.- i have a product_item field (wich is a lov and user choose one value), so i need to call a function (sending it the selected value product_item) that will return me some data about the product i selected, for example :

2.- i need to determine the result of two items operations: total := final_quantity - start_quantity the user will introduce start and final quantity and i will determine the total.

from jobs aI would like to show a count from another table where the jobid = jobid from the above sql.The problem is I don't know how to refer to the jobid in my extra sql.Here is my extra sql for the new count column.
(select count(1) from jobs a, loghead b, dba_scheduler_job_run_details c where a.logid = b.logid and b.session_id(+) = c.session_id and a.jobid = :P3_JOBID) no_of_related_jobs.

I have an IR where I have to show a column in report, but hide it while downloading to CSV.
I get this by having a condition on this column - NVL(:REQUEST,'EMPTY') NOT IN('CSV','XLS','PDF','XML','RTF') I also have a column where I have to hide it in the report, but show it while downloading to CSV.
I am able to hide it, but this column doesn't show up while downloading.I am using this condition on this column NVL(:REQUEST,'EMPTY') IN('CSV','XLS','PDF','XML','RTF') APEX - 4.0.2
In a classic report, I'm using the Sum functionality and breaks by First Column to get subtotals and report total. I Repeat Headers on Break which works great for the subtotals but I would like for the report to display the column headers above the report total for easier reading. If the last grouping has a lot of data, the user needs to scroll up to read the column headers when looking at the Grand Total.
Is there a way to Repeat Headers prior to report total?
I'm using apex 4.1.1 And i want to use a Date Picker item on my page. This works, but.. When a user selects a date you can see the date highlighted. But in the "textarea"corresponding tot the datepicker is not showing the date. This shows the date after clicking the close button.
I would like to show the date directly after selecting a new date.
Statuswhen they entered the details and submitted the form the data will be stored in LEAVE table. later on the applied leave will be approved or rejected and the STATUS column will be updated. Is this possible to show the last leave applied status as a alert message when they are logging in ?
Is it possible to detect the status of Hide / Show Region.
I have three hide/show regions RX,RY,RZ. When an event EX happens, then region RX should expand and the rest of the region should collapse. When an event EY happens, then region RY should expand and the rest of the region should collapse. ........ ... We can use this JS on DA to change the status of a region:
