APEX Forum Sticky

After starting to update the OTN forum FAQ, I decided that I would try to get the APEX 'Welcome to the forum' sticky amended to include links to docs, and maybe some amended ettiquette guidlelines etc.
To this end I contacted Sharon Kennedy at Oracle who owns the thread and she has agreed that if we, as a community, can come up with the new wording and I e-mail it to her, she will put the content up for us!
This is a great opportunity for us, so please get your comments in and I'll start writing something up. I think I leave this thread going for a week so that everying can get their ideas in before coming up with a final version.
This has been suggested on numerous occasions and each time nothing has come of it, so I decided to take action!
Maker the most of the opportunity (remember it can also save you a lot of posting because we can just refer people to this one place).
Cheers
Ben

APEX Forum sticky announcement: suggested changes to content

Would it be possible to reconsider the content of the Forums Etiquette / Reward Points sticky announcement on the Application Extress forum?
For the benefit of those whose first language isn't English (or indeed French), could the archaic word Etiquette be removed, by changing the subject line to, for example: How to use this forum or Forum best practices etc. It's possible some users don't recognise the term "etiquette" and therefore don't find and read the guidance within.
- When asking a question, provide all the details that someone would need to answer it. Consulting documentation first is highly recommended. It would be useful if what these details should be was spelled out: APEX version, database version, table descriptions, sample data, SQL or PL/SQL already tried, browser(s) and version(s) etc.
As well as recommending consulting the documentation, a link to the APEX documentation page would also be helpful.
Addtionally, a suggestion to try searching the forum (with link to search page) before posting should be included: a huge number of questions in this forum are answered in previous threads.

Forum Sticky???

Is the forum sticky today?
Or is it just my neck of the woods ....

Well suprisingly for me it seems fine today.

hello
In shared Components\report queries or \reprot layouts of ApEx 3.2, has written
Named column report layouts are file based. To change, download the current file using the download button on this page, then modify the file as needed. Afterwards, upload the modified file as a new report layout.
How can I modify an XML extension file with other tool than BI publisher? (generated by BI Publisher )

Oracle Forums - Apex free Forums on Source Forge?

Can someone from Oracle confirm this question?
I had heard or read somewhere that Oracle was going to be releasing their Forum application to the public?
This way everyone could use Oracle's forum tool for their own needs.
This would be one of the of the free applications that comes with the Apex tool as a Standard application.
Has anyone heard any stories like or similar to this?
The reason I'm asking, is if Oracle isn't going to do this, then I guess we should all try to help and contribute by copying some ideas of what already exists in existing Forum tools and add it into the Source Forge - Oracle Apex Forum tool.
Get back to me
Thanks.

Hello,
Did you read the second sticky link in this forum?
the one titled "Application Express apps on Sourceforge"
here is the link that is contained in that http://apex.oracle.com/pls/otn/f?p=apexsf

Apex conditional field in "SQL Query (updateable report)" region

I have a multi-row region that displays values and allows entries in a number of fields. I should like the fields to be conditional in that they do not permit entry, but still display, if certain conditions apply (e.g. older rows greyed out). Can this be done?
I have searched Google and this forum but all the threads I have found relate to field formatting or display/non-display.
Many thanks in advance Dave Barber

I should like the fields to be conditional in that they do not permit entry, but still display, if certain conditions apply (e.g. older rows greyed out). Can this be done? Almost anything can be done, often in multiple ways. Which are appropriate may be dependent on a particular implementation, the skills available to implement it, and the effort you're willing to expend on it. Hence it's necessary to provide full details of what you've done so far...

Image is not displayed in APEX Form with APEX utility Function

Dear APEX experts,
As i am new to the oracle apex development. I have just created the basic employee information form in which i upload the photograph of the employee. The photograph gets uploaded but it does not display properly. I have already referred the sample database application to display the image. Moreover, i have followed the same steps as it is used to display the product image in that application. Still i am unable to get result. I am getting following output:
<img src="apex_util.get_blob_file?a=35682&s=101496289174102&p=15&d=10639237623242912156&i=10639236703270912154&p_pk1=21&p_pk2=&p_ck=FCA12832591A1C706D76FDD589E551A2" />
Please help me seniors to solve this issue. How to display the image using this utility.

Hence , in my application the code is not rendered perfectly and syntax is not completed.
following characters are rendered like this.: &lt , &quot , &gt , &amp.
So, is this the reason of not displaying the image???Yes.
To get a Display Item to render as HTML, in the item definition Security section set Escape special characters to No.
For a report column, ensure the Display Text As report column attribute is Standard Report Column rather than the default Display as Text (escape special characters).
Use a Display Image item and declarative BLOB support instead of this clunky manual method.

Stored Procedure used as a data source for an Apex report

Just wondering whether anyone has used a Stored Procedure as the data source for an Apex report. An option to select Stored Procedures(s) as the data source does not appear within the IDE (only displays Table, Views, Functions).
Do you have to return the definition of the Stored Procedure via a function ... if so, how is this done ?
Thank you.

Do you have to return the definition of the Stored Procedure via a function ... if so, how is this done ? When asking a question about "reports" it's firstly essential to differentiate between standard and interactive reports. Standard reports can be based on tables, views, SQL queries, or PL/SQL function blocks that return the text of a SQL query. Interactive reports can only be based on a SQL query.
"Stored Procedures" are therefore not an option (unless you are using the term loosely to describe any PL/SQL program unit located in the database, thus including functions). What would a procedure used as the source of a report actually do? Hypothetically, by what mechanisms would the procedure (a) capture/select/generate data; and (b) make this data available for use in an APEX report? Why do you want to base a report on a procedure?

This change has to be done Dynamically. Without Entering it Manually.Also clarify what you mean by "instance". An "APEX instance" refers to the APEX installation in a database. The "APEX instance" does not have a specific name property, and would therefore usually be referred to using the database name. Or do you mean the APEX workspace containing the application?

Checkbox Item: character string buffer too small (APEX 4.0. - 4.2.)

Hi all,
I'm currently running the Oracle Application Express 4.0.2 on the Oracle DB 11g and thinking about the APEX upgrading to current 4.2. version. We have there quite big application used by the inernal employees so prior I need to test, if the migration will work.
I installed the new server with database and the APEX 4.2. and import the current application. Everything seems to working good except few checkboxes, which returns me the error: "ORA-06502: PL/SQL: numeric or value error: character string buffer too small."
LOV (Source) Code of Checkbox Item:
SELECT email as display_value, id as return_value
FROM users
WHERE <some conditions>;
In the current version 4.0.2. I get the checkbox item (total count of the rows approx. 650), but in the 4.2. I get this "string buffer too small" error and the page could not be rendered (if I add to the same query limitation: "rownum<242" it will display the item).
Could you please help me with this issue? Any idea, what I should set up in the new APEX to get the same results or you see there any limitation, why it does not work in the new version, but in the old version the same SQL works fine?
Thank you all in advance.
Regards,
Tomas.

Why you are hitting this limit in the new instance may be due to differences in data or the database configuration (e.g. character set) rather than changes introduced in APEX.
Is the data exactly the same? Is the database configuration the same? When you limit the number of rows so the checkboxes are displayed and view the page source, is there any difference in the HTML used to render the checkbox form elements between the two versions?
That said, from a usability perspective 650 LOV options is rather a lot, and your application may very well outgrow this limit naturally in any version of APEX as more users as added. It is probably worthwhile thinking about other ways to display these options.

How to change column type at runtime in Apex 4.0

Hello everybody,
I´m newbie as Apex developer using Apex 4.0 with OracleXE 11.2, and now my problem is:
I have a tabular form where one of the columns, when calling the form, is a Display Item, so that you cannot change existing values.
I want, when adding a new row, that column become a Select List (named LOV) based on a query that exclude existing values in other rows already inserted.
Can I change that Display Item to Select List (named LOV) programmatically at runtime?
If not, what other options do I have?
Thanks a lot for any help,
Greetings

I would like to create a new custom that needs to be developed in my application.Can we be clear on what you are asking for? A complete custom theme is a major undertaking. Customizing or overriding aspects of theme look and feel is relatively straightforward. Creating or customizing component templates within a theme is also pretty simple.
As a developer i dont have access to either download or upload files from themes folder.Why not?
You can always download theme resources through the browser. When running an application, view the page source in the browser. The page <tt>head</tt> element will contain a link to the theme style sheet like this:
<link rel="stylesheet" href="/i/themes/theme_25/css/4_2.css?v=4.2.1.00.08" type="text/css" />Add the server to the URL in the style sheet URL and type it into the browser address bar:
http://apex.oracle.com/i/themes/theme_25/css/4_2.css?v=4.2.1.00.08The browser will download the theme CSS.
To identify and access other resources like images referenced in CSS, use the web inspector in decent web browsers with real developer tools like Firefox+Firebug, Safari or Chrome.
Can anyone guide me how that could be implemented in my application.Developing a complete theme requires a good knowledge of HTML and CSS (and increasingly of JavaScript and a JS framework like jQuery). It's beyond the scope of this forum to provide information on the basics of HTML and CSS, and/or web and UI design in general.
The documentation contains information on managing and customizing themes and templates. Also see this Cloning your Corporate UI with HTML DB blog post (HTML DB was the former name of APEX).
The web server file system is the best location for theme files. If you really can't get proper access to this (as on hosted environments like apex.oracle.com for example), then the APEX repository can be used as the location for the required theme CSS, image (ignore the #IMAGE_PREFIX# stuff there—it's in the wrong place; repository images are accessed using #WORKSPACE_IMAGES#) and script resources.

Coloring Cells in Apex 4.2

I'm trying to figure out how to change the cell background color in an Apex report. I've tried following instructions that I've found on here and on the net with no luck. I'm wondering if maybe the instructions are not valid for 4.2.
Anyway, has anyone had any lock with setting a cell background-color in Apex 4.2 based on value?
Thanks!

Can I use css3 in apex 4...database 11g xeIn APEX all presentational aspects of an application (including font size) are controlled using a combination of (X)HTML and CSS via themes and templates. You need to have an understanding of these web technologies to make best use of APEX. If you're not familiar with them you're advised to get at least a basic understanding by spending some time on the tutorials here: start with HTML, then XHTML, CSS, Javascript and the HTML DOM.
CSS3 features can certainly be used in your APEX themes and applications. Any problems are not likely to arise there, but in whether these features are supported by the browsers/versions used when running them. These sites may be useful in determining whether it's worthwhile for you to use CSS3 to implement a particular feature:
http://www.impressivewebs.com/css3-browser-support/
http://caniuse.com/
Using progressive enhancement techniques will allow you to introduce CSS3 features for browsers that do support them while still making applications accessible in those that don't.
