I am working with APEX 4.2. I have a schema with tables and views create and with data all tables.
Question : There is some way that I can generate automatically a application for all those tables & views. I remember that version 2 have this option.
I have an image that shows flags of 2 countries... I want to show revenues that they generate every day. is there a way to add text to the image (on it) using values from a table.

I'm trying to automatically update the value every time a new row is inserted but I'm having trouble with the code.
DECLARE
varInt NUMBER :='SELECT MAX(IMAGE_ID) FROM IMAGES';
begin
create_blob_thumbnail(varInt);
end;I get the error +'ORA-06502: PL/SQL: numeric or value error: character to number conversion error'+
If I run the query SELECT MAX(IMAGE_ID) FROM IMAGES, it returns the last row ID I created just as it should. The create_blob_thumbnail(varInt) procedure works fine if I manually put in a number.
Apex 3.2. I have a page with a button. Once the user clicks the button a call is made to a procedure in a package.This procedure acesses a couple more procedures and functions, inorder to import data from one table to another. If the procedure takes more than 5 minutes to complete, the user receives an error message.This is actually the error message the user should get if he tries to do an import while another user’s import is running. Is it possible that if the called procedure doesn’t return in under 5 minutes the page is reloaded and the procedure called again resulting in the above error message.

I found this tutorial how to save and access report.Storing and Accessing Reports in the Database In that tutorial report is saved onclick.Is there a way to automatically email report everytime report is generate or I should first save it (PDF, CSV,..) with SQL script and then email it? I also found that in Interactive report there is page process that can send e-mails. Is it possible that page process send e-mail with report or report should be also saved before sending? The reason for this is that we want to have a history of created reports.

we would like to generate pdf out of apex. as long as we have text (IRR) WITHOUT special characters (öäü), everything is working fine.when we have this characters in a text-columng (IRR), then we get a .pdf with the following content:

I have a requirement create graphs, charts and maps based on data from a data warehouse (dw).
As I see things, there are two possibilities: Graphs, charts and maps based on an XML fileGraphs, charts and maps based on Oracle tables Both would contain small data sets that will allow for quick response.
The intent of these graphs, charts and maps is to generate a dashboard that would allow the user to quickly drill down to the desired warehouse data. The proof of concept has already been validated using the Oracle table scenario.
My question is whether or not this could be accomplished reading xml files for generating the same set of dashboard items? My Oracle database and APEX environments configuration are as follows:
NLSRTL 11.2.0.1.0 Production Oracle Database 11g Enterprise Edition 11.2.0.1.0 64bit Production PL/SQL 11.2.0.1.0 Production TNS for Solaris: 11.2.0.1.0
ProductionApplication Express 4.2.2.00.11APEX Listener Release 2.0.2. / Tomcat
An Oracle database directory has been setup and is accessible to our APEX application.
We have generated a fancy custom interactive report, in which the columns of string type, but can hold string, numeric or date values. However the type of values are uniform for a particular column. The end users wants to use the numerical values for generating charts, but, being a string column (though the data is numeric), it throws an error and they could not generate the chart. Is there any way to make use of this string column type numerical data for generating chart?
The current version of apex is 4.1.
I would like to generate automatically at a certain interval a E-R diagram with all the tables in a schema and put the file on a certain location. My problem is the word AUTOMATICALLY. Toad Data Modeller does everything I want except this.
View 11 Replies View RelatedWe have integrated Oracle Access Manager 11gR1 with Oracle Apex 4.1. The OAM-Apex integration is working fine. Now we want an additional header variable to be passed from OAM to the Apex application. This new header variable will be user's sAMAccountName in Active Directory. OAM is integrated with AD and the AD users are successfully able to access the Apex applications.
The three header variables which are configure in OAM right now are:
Header variable name Value
1. OAM_REMOTE_USER $user.userid
2. OAM_REMOTE_USER_EMAIL $user.attr.mail
3. OAM_REMOTE_USER_GROUPS $user.groups
We need an additional header variable as mentioned below:
Header variable name: OAM_SAMACCOUNTNAME
Value: $user.attr.samaccountname
The new header variable was added in the OHS server's dads.conf file like shown below:
=========== dads.conf =============
...
PlsqlCGIEnvironmentList HTTP_OAM_REMOTE_USER
PlsqlCGIEnvironmentList HTTP_OAM_REMOTE_USER_GROUPS
PlsqlCGIEnvironmentList HTTP_OAM_REMOTE_USER_EMAIL
PlsqlCGIEnvironmentList HTTP_OAM_SAMACCOUNTNAME
But we are not able to read the value of this attribute in the Apex application.On the Apex application, we have a text box which shows the value of this header variable. This textbox is attached with the following stored procedure call to fetch the header variable:
===================
begin
:P1_HEADER_VALUE := owa_util.get_cgi_env( 'HTTP_OAM_SAMACCOUNTNAME' );
end;
The textbox shows the correct value if HTTP_OAM_REMOTE_USER is passed to the get_cgi_env method but does not shows anything when HTTP_OAM_SAMACCOUNTNAME is passed to the same method. if I am missing some configuration to pass the HTTP_OAM_SAMACCOUNTNAME haeder variable from OAM to Apex.
I have multiple application set-up using session sharing within the workspace.Technically all works fine, however it does not play nice with user behaviour.
Example:
Users logs into APP_ID:100. Since he isn't authenticated yet, he provides user/pass and the APP_SESSION is authenticated.
Now if the user switches using to another application (using a link provided in application 100) he gets redirect to APP_ID:101:APP_SESSION all is fine.
The session is already authenticated, the application shares the session and the user gains access to app 101 without having to authenticate again. All's fine!
However users don't behave they way. Instead of using an easy link in the application. They will use their own bookmark or type in the url for app 101 manually. That way the next application is either called with f?p=101:1:[SOME OLD SESSIONID FROM BOOMARK] or f?p=101 (with no further page or session info) In both cases instead of using the already authenticated session apex spawns a new session, which of course isn't authenticated yet thus forcing the user to authenticate and come complaining they have to login again.
Similar behaviour problems exists when the user opens a browser and tries to open both applications in each in a tab next to each other.Both tabs fetch there own initial session id and start writing it to the same cookie each in turn invalidating the other tab's session.These can lead to some fanatic ping pong actions. Thus it's impossible to open 2 applications sharing session in the same browser.
Is there any remedy for these situations?Can apex be as smart as for instance first trying to resume the session stored in the cookie and only if that session is invalid, start a new session?
how to use checkbox item, and trying to get checked options values via application global arrays. So, this may be quite simple question, but I'm completely stuck here...
When I was looking through various threads and guides, I've encountered checkbox corresponding array names like "g_f01" - "g_f50". And so far i saw that these names are derived from item name in generated HTML code, for example:
<input type="checkbox" name="*f10*" value="3" />
And this one stands for array name "g_*f10*".However, when I tried to do the same thing - i receive item name which looks like "*p_v04*", and therefore, I can't figure out, which array name should I choose to adress it properly.
My generated HTML snippet:
<input type="checkbox" id="P6_ANSWER_0" name="*p_v04*" value="3"/>
i want to display a list of all users on a page those currently accessing or using the application. How do i accomplish this requirement?

opened the SQL that was created from the export utility and this is where it errored:

Unless I'm not understanding this error it means that it can find the ACTION part that is attached to the WHAT part of this Dynamic Action? The Dynamic Action does work when the application is run (in Development)also, there are 3 others that are similar to this one. The export was created by the export utility in the Application Builder.
If I export only the page and import that into Production the import is successful and the page runs correctly. This is error is happening only when I try to import the entire Application.There are many other changes made which is why I was trying to do an Application export/import instead of individual pages.
I have to modify the Form layout of an existing application (Application Express 4.0.2.) where the data for each field is retrieved using SQL statements
Presently the form looks something like this and the Data for each field is rendered properly in this layout:
UNIT # : 123456
ADMISSION #: 2012101510 DISCHARGE DATE: ADMISSION DATE:
FIRST NAME: JON LAST NAME: DOEFIRST NAME, LAST NAME and UNIT # are all "Display Only" item type.
What I'm trying to do is to move "FIRST NAME" underneath "LAST NAME" and "UNIT #" next to "LAST NAME" This part is very simple. However, the issue I'm having is as soon as the "UNIT #" is moved next to "FIRST NAME", the data for "FIRST NAME" and "LAST NAME" simply disappear
This is how it looks
ADMISSION #: 2012101510 DISCHARGE DATE: ADMISSION DATE:
FIRST NAME: UNIT #: 123456
LAST NAME:
I have played around for hours and even created from scratch a new page with a new form using SQL statements to pull the data for each field, only to get the same result.
I have an application item that receives a web service result. This result is like 'MARIA','JOSE','JESUS'. I'm using this string into the parameters of the interactive report, but this is not recognized. I'm showing the content of the application item into a pl sql region and the content is 'MARIA','JOSE','JESUS', when I include this application item into the query, the IR shows me 'MARIA','JOSE','JESUS'

I need to change "File Character" when I export application with Apex 4.2.1.00.08 version, but this option, is not possible. The ComboBox already select with
"Unicode UTF-8]', but I need "ISO-8859-1 - Europa Ocidental",
how can I do change it?
My question is, if I define an object type (create type ... as object ...) is it possible to hold a variable of this type as the session level? For example, if I am creating an order using multiple web pages, it would be much easier (and intuitive) to create and manipulate an order object than to hold the data in generic collections.
If that is not possible, is there some way to make a generic Apex collection appear more application specific? By this I mean some way to map the columns C001, C002, ... to more intuitive names such as CUST_NO and ORDER_DATE. I had considered possibly creating a view of the APEX_COLLECTIONS view which would rename the columns but then I would also have to create a bunch of instead of triggers if I wanted to update it as well.
