Apex 3.2 - Global Variables loosing value!

Hello Everyone,
I am using Oracle Apex version 3.2. I am using global variables in my queries.
I found that some times but not always these global variables loosing their
value. How I can resolve this issue?
All replies will be appreciated. Thanks in advance for your replies.

Hi, thanks for your answer.
The king of caché I was talking about is something like this:
* I get a table record (rowtype) from a query accesing the table by PK.
* I store the value of my PK and the record I got in PL/SQL and go back to the app.
* Then, if I need to get another record from my table accesing by PK I compare the PK value I got in memory:
- It is the same value: return the record (in this way I don't have to query my table).
- It isn't the same value: query the table with the new value and store the record and the PK value.
It is easy to do this in applications like Forms or .NET, but can I do it with APEX?
Thanks.

Unit Testing and APEX Global Variables

We've recently started to unit test our database level PL/SQL business logic.
As such we have a need to be able to simulate or provide output from PL/SQL APEX components in order to facilitate testing of these components.
Some of the most obvious portions that need simulation are:
1. The existence of a session
2. The current application ID
3. The current page ID.
We currently handle requirement #1 by using apex_040100.wwv_flow_session.create_new
We handle 2 and 3 using the apex_application.g_flow_id and g_flow_step_id global variables.
I'm just wondering, how safe is it for us to use wwv_flow_session.create_new to simulate the creation of a session at testing time for those things which need a session?
I've also noticed that there are apex_application.get_application_id and apex_application.get_page_id functions whose output is not tied to the global variables (at least in our current version).
Is it safe for us to expect that we can set these global variables for use in testing or is apex moving to get_application_id and get_page_id functions away from global variables?
Will there be corresponding set_application_id and set_page_id functions in the future?
Sorry for the question bomb. Thanks for any help.

My first question would be why do you need to establish a session to test your PL/SQL?
wwv_flow_session is a package internal to APEX, and you should probably leave it be.
The get_application_id procedure you refer to is in apex_application_install, which is used for scripting installation of applications - not get/set of page ID like you're describing.
If you're uncomfortable using apex_application.g_flow_id, you can use v('APP_ID') or preferably pass the app_id/page_id as parameters to your procedures.
Your question seems to have a few unknowns, so that's the best I can describe.

How to get the value of the global variable of test stand in labview User interface?

Hi.
Can anyone Please share examples and tell me to how access the test stand global variable using labview user interface.
Solved!
Go to Solution.

I'm not surprised that what you are doing doesn't work. The Start Execution UI Message is triggered when the user clicks a button to start an execution. Realize that most executions go through a process model. So you could be looking at the sequence context of the process model and not your client sequence file.
I recommend reading that link I posted above. UI Messages are your best bet but you cannot just piggy back on an existing UI Message like this. They may not be getting sent at the time you need them to be. The only way to ensure you get what you want is to trigger one yourself at the right time.

How can I define global variable in user exit whic I can use anywhere.

Hi all,
How can I define global variable( Table ) which I can use when it come back to same user exit where I defined and stored some data.
What I mean is I want to define 1 global table.
In user exit when it comes I store some information. and again when it will come I will have that stored information so I can use it.
Thanks a lot in advance.

You can use EXPORT TO MEMORY ID and IMPORT FROM MEMORY ID Statement for this.
EXPORT T_ITAB FROM T_ITAB TO MEMORY ID 'ABC'.
IMPORT T_ITAB TO T_ITAB FROM MEMORY ID 'ABC.'

User Variable in Business Rule or Global Variable

I wanted to call the User Variable value of Planning application under the Globel Variable of Default Value. Example I have created one Globel variable under the Default value the user varible value need to pickup so any thought how I can do this.
I know in the Form if you use &UsrVar this will show the user variable value in the Data form but it is not showing the User Variable value in global variable or inside the Business rule.It is giving an error message there is no substitution variable has been defined. Please explain.
Thanks in Advance,

Hi,
User variables are meant to be used in web forms and web forms only. You can certainly pass their values to business rules when you used them in POV or page section of the form during save. All you need to do is to create another business rule (local or global) variable in business rule on the corresponding dimension and use it in your business rule. If you enable running the business rule on save and using the form values for variables options in form properties, business rules would replace the values of business rule variables with the values that are set in user variables.

Use global variable to transfer user parameter in some Vi

Hello,
I have troubles when I use a global variable to transfer the parameter to a first Vi (user interface) to a second vi (acquisition interface).
In the first Vi, the user paramater is wrote to my global variable.
In the second Vi, the acquisition parameter is read to my global variable.
This 2 Vis are include to a master Vi who synchronized by the error bus.
The problem :
For the first use, the user parameter is transfer to the global variable but the acquisition vi read the old parameter. In the second use, acquisition vi read the first use parameter.
After I use the IN/OUT parameter subvi and i have too this problem.
Thanks for help.

Labview uses the dataflow to chain the execution. That is, as soon as one item of data is ready is is presented to the next stage.
Global (or local) variables do not easily fit in there. A variable is always present and ready to give away it's data. It does not matter that you write to it in one vi. Another vi, that is running concurrently is not aware that the content may have changed.
Especially if you reference variables outside of loops, the value is taken just once and never updated. Be aware! If in doubt, use the tracing facilty (the light bulb) to follow the data flow.

Apex Global Variable like D2K

HI,
Previously my application was develop in d2k6i where i use global variable to keep user_id available in every forms...
is it posbile to declare global variable in Apex ?
Thanks
Engr.M.K Chowdhury

Just to extend Andy's point a little further, you may want to look at some of the built in Substitution Strings that APEX offers you right out of the tin:
http://download.oracle.com/docs/cd/E14373_01/appdev.32/e11838/concept.htm#BEIFGFJF
You may find that Oracle provide you with the global value you need but follow Andy's advice for creating your own.

APEX: Declare global variable in APEX

Hello All,
Can anyone tell me how to declare global variable in Process(Pl/sql code) in Oracle APEX.
Thanks,
Jiten

There is nothing like Global Variable that can be declared in Process in Apex.
Look up Shared Components > Application Item. Maybe that is something that meets your requirement.
Alternate, use Page 0 items.

Apex- global variable declaration

Dear Friends
I am very new to Oracle applicaiton express,
Please let me how to declare global variable in an applcation. The variable should be accessible throught ot all the pages in that applicaion. Any one can help?

Hi,
use an application item for that purpose.
Just navigate to Shared Components->Application Items and create what you need.

Setting the value of an Application Item (setting a global variable);

In APEX 3.2.0.00.27, I need to initialize a global variable to 0 to implement a variable for testing to see if anything on the page has changed. Will update to 1 when certain select lists on the page are changed. Have read through some similar questions and replies within the forum as well as other blogs and sites. So, I believe what I am doing is the way to go about this. Unfortunately, my initialization of an application item/global isn't happening yet. here's a rundown of what has been implemented:
1) created an application item, G_CLASSIFICATION_ID_NEW in the shared components;
2) created Javascript (JS) function called by addLoadEvent in the page html header region so when the page loads, the G_CLASSIFICATION_ID_NEW global/application item should get set to 0 with the following JS and using AJAX and htmldb_GET:
<script type="text/javascript">
function initVars()
alert("before get initvars");
var get = new htmldb_Get(null,$x('pFlowId').value,null,22);
get.add('G_CLASSIFICATION_ID_NEW', 0);
gReturn = get.get();
if(gReturn){
alert(gReturn.value);
get = null;
alert("after get initvars");
alert("before call to initpage");
addLoadEvent(initVars());
</script>
I've used the htmldb_Get with success for populating other global variables and running On Demand Processes with onchange JS calls in the html form element attributes within select lists on the page. Afterwards, I can check the globals via the Session window and searching on Application Items. Unfortunately, I'm missing something because my G_CLASSIFICATION_ID_NEW never gets populated when I load the page. The alerts all popup when the page is loaded, so I know the script is being executed when the page loads. the alert(gReturn.value) comes back undefined. And, needless to say, the G_CLASSIFICATION_ID_NEW to 0 is not occurring.
I've tried the htmldb_Get with it calling an application process and without (set to null). From what I've read, you shouldn't need to call an on demand process to have the get.add set the global variable. Then again, this could be where I'm going wrong. however, as I've mentioned, this works for other functions called from an onchange to populate an application item, but the page has already loaded when the onchange(s) get executed. They may work because the page is already loaded when the onchange is called. My point here is that my other On demand processes are NOT setting or changing the global variables at all. The globals are getting set with the get.add(<app item>, <value>) portion of my other JS functions within the HTML Header region. So, I'm inclined to believe that I don't need the 'application_process=<some_odp>' parameter set, but if that's not true, please let me know. if so, what would need to be in the on demand process--ie, what would be the purpose of the get.add(<application item>, <value>) if I set the global variable in the on demand process because that's the only thing I could think of doing within an on demand process for this?
If somebody can point out what I'm not understanding or failing to do here, that would be great. I'm doing fine with APEX, but wouldn't consider myself a guru with it just yet. I'm definitely not a JS/AJAX guru, and when things like this go astray, I get bogged down because I'm not sure of the problem. So, I'm hoping you gurus who monitor this forum can get me going in the right direction.
thanks,
bob

Hi Jari,
Does that javascript work if you place it some of region footer on page 22 ?Yes. I cut it out of the html header of the page, and put it in the footer of the first region on the page. It initializes the variable. Putting it into the footer of the first region on the page should work for me instead of having an extra region on the page that's being picked up from page 0.
Is your page 22 authentication public ?No. This particular page is set for an ADMINISTRATOR only. That said, I am logged in as an administrator. So, I cannot see why setting authentication should make a difference as long as I have that authentication/authorization. Also, there will be other pages where I want to use this script or a similar script, but again, those pages will not be open to the public. the authentication will be "role" based where a user will not necessarily have to be an administrator, but they will have to have a certain role to access the page. Is there a known problem or something that precludes a html header JS script from doing an addloadevent when authentication is NOT public?
thank you,
bob

Can I Access the Value of a Global Variable in a Trigger

I'm using a Global variable in a Package which i use in the BIU Trigger to populate a column. After assigning the value for that global variable, I run an INSERT in the same package. But I find only the default value of the Global variable populated in the column. Can I use a Global Variable in a Trigger? Is there any way to put in a common value across all the tables in an application for all DMLs of a particular session?

Helios,
I'm already having the same setup mentioned in the thread. And I'm doing exactly whats given there. But the issue seems to be something different. I'm assigning the value to the Global Variable in the Package through Apex. Here's the Package Code:
CREATE OR REPLACE PACKAGE Schema1.SPMS_SECURITY_PKG
AS
X_app_user_id NUMBER DEFAULT -1;
FUNCTION USER_ID RETURN NUMBER;
END SPMS_SECURITY_PKG;
CREATE OR REPLACE PACKAGE BODY Schema1.spms_security_pkg
AS
FUNCTION user_id
RETURN NUMBER
IS
BEGIN
-- RAISE_APPLICATION_ERROR(-20001,'USER ID'||'*'||X_app_user_id);
RETURN NVL (x_app_user_id, -1);
-- RETURN NVL (sys_context('USERENV', 'CURRENT_USER'), -1);
EXCEPTION
WHEN OTHERS
THEN
RETURN -1;
END;
And Here is the Trigger Code:
CREATE OR REPLACE TRIGGER Schema1."USER_DETAILS_TRIGGER"
BEFORE INSERT OR UPDATE
ON PMS_SICAL.SPMS_USER_DETAILS REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
BEGIN
IF INSERTING
THEN
:NEW.created_by := spms_security_pkg.user_id;
:NEW.created_date := SYSDATE;
:NEW.START_DATE := SYSDATE;
ELSIF UPDATING
THEN
:NEW.updated_by := SPMS_SECURITY_PKG.X_app_user_id;--spms_security_pkg.user_id;
:NEW.updated_date := SYSDATE;
END IF;
END;
But I always get -1 in the both in the table after the DMLs.
