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.

Syntax for declaring global variable in report

Hello all,
Kindly let me know syntax for declaring global variable in report?
Thnks,
SUnny

Hi Sunny,
All data declaration in the main program is global.
Only if you do some data declaration withtin the subroutines then the scope of the variable is limited to that FORM ....ENDFORM.
As you read in the above reply for a global variable in FM you need to declare in the top include.
This means that you want this variable to be made available to all the Function Modules in that Function Group.
If you want to make the variabe be available only within that FM then do the declaration in the source code itself.
hope this explaination helps,
Taher.

Hi Kannan,
I would suggest using a comma delimied list or putting it in the database.
ArrayList myList = new ArrayList();
myList.Add("one");
myList.Add("two");
myList.Add("three");
string comma = "";
// store the array in the session state
foreach (string s in myList){
Session["persistedArray"] += comma + s;
comma = ",";
To get the array back
if (Session["persistedArray"] != null){
ArrayList myList = Session["persistedArray"].ToString().Split(new char[1] {','});
If your array is storing objects, you should use the database.

How to declare global variables using another global variable in ODI

I am declaring a gloabal variable using another global variable.
say for example:
I have a global variable empid.
I am decalaring another global variable empname in refreshing tab of global variables and the select statment is
select empname from emp where empno = #GLOBAL.empid -------if i write like this i am getting error as invalid character.
select empname from emp where empno = '#GLOBAL.empid'-------if i write like this i am getting error as invalid number.
I have kept the datatype as numeric and action as non persistent
Please help
Thank you in advance.

Hi,
You cant test/refresh empname standalone.
You need to create a new package drag and drop both variables and make them as refresh variable and execute that package and test.
Flow,
empid----> empname
Thanks,

10g declare :global variable error (bad bind variable)

In a 10g form, I tried this code in the pl/sql block and in the spec of a library package
begin
:global.config := 'x';
...upon compile, I get an error
"bad bind variable"
...encountered the symbol "GLOBAL" when expecting one of the following...It doesn't like :GLOBAL.variablename := 'x';
What am I doing wrong?
Thank you.

globals are allowed in librarys, but in libraries you have to use COPY and NAME_IN to access objects you access via :-logic in forms-modules, e.g. setting the global would be like
COPY('X', 'GLOBAL.CONFIG');Edited by: aweiden on 29.10.2008 19:33

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.

Using global variable read status

Hi Experts,
I need to change the Note based o the Service Ticket status. I declared global variable as a string in ZL_ICCMP_BT_BTSHEADER_IMPL (Component: ICCMP_BTSHEAD; View: BTSHeader)
And I am passing the Status to this global variable using the GET and SET methods of the STRUCT.ACT_STATUS attribute in BTSTATUSH node in same component and view.
I referred this global variable in DO_PREPARE_OUTPUT of the component ICCMP_BTTEXT/TextView to set the Note as shown below.
if ZL_ICCMP_BT_BTSHEADER_IMPL=>GC_STATUS = 'E0001'.
I would like to know whether this approach is the best way to read status or any other optimistic approach is there to follow for my this scenario. Please advise me.
Thanks
Chand

Hi Basha,
If you are using static variables, i wouldn't recommend using this approach.. there are better approach to get/set values in web client session which avoids setting/clearing static variables etc..
you can follow below approach..
1. To Get/set the variable in ic session to avoid the static variable.. for eg global cuco is available which you can use for this purpose.
lr_bdc type ref to if_crm_ui_data_context.
lr_bdc = cl_crm_ui_data_context_srv=>get_instance( me ).
check lr_bdc is bound.
Using SET_DATA_ATTRIBUTE set the attribute value and using GET_DATA_ATTRIBUTE get the attribute valueu2026get_attribute, set_attribute
read current BuAg if exist
lr_buag ?= lr_bdc->GET_DATA_ATTRIBUTE( 'CURRENTBUAG' ).
Here "CURRENTBUAG" is the attribute name, you can give any attribute name while setting and get the same attribute value via get_data_attribute.

What's the difference between global variables and instance variables?

hi im just a biginner,
but what is the difference between these two?
both i declare them above the constructor right.
and both can access by any method in the class but my teacher said
global variables are not permitted in java....
but i don't know what that means....and i got started to confuse these two types,,
im confusing.......
and why my teacher said declaring global variables is not permitted,,,,,,
why.....

instance variables are kindof like Global variables. I'm not surprised you are confused.
The difference is not in how they are declared, but rather in how they are used.
There are two different "styles" of programming
- procedural programming.
- object oriented programming.
Global variables are a term from Procedural programming.
In this style of programming, you have only one class, and one "main" procedure. You only create one instance of the class, and then "run" it.
There is one thread of control, which goes through various methods/procedures to accomplish your task.
In this style of programming instance variables ARE "global" variables. They are accessible to all methods. There is only one instance of the class, and thus only one instance of the variables.
Global variables are "bad" BECAUSE you can change them in any method you like. Even from places that shouldn't have to. Also if you use the same name as a global variable and a local variable, you can cause great trouble. This can lead to very subtle bugs, as the procedures interact in ways you don't expect.
The preferred method in procedural programming is to pass the values as parameters to the methods, and only refer to the parameters, and local variables. This means that you can track exactly what your method is doing, and what it affects. It makes it simpler to understand. If you use global variables in your methods, it becomes harder to understand.
So when are instance variables not global variables?
When you are actually using the class as an Object, rather than just a program to run. If you are creating multiple instances of an object, all with different values for their instance variables, then they are not global variables. For instance you declare a Person object with an attribute "firstname". Your "main" program then creates many instances of the Person object, each with their own "firstname"
I guess at the end of all this, it comes down to definitions.
Certainly you can write procedural code in java. You can treat your instance variables, for all intents and purposes like global variables.
I can only think to show a sort of example
public class Test1
   User[] users;
   public void printUsers(){
     // loop through and print all the users
     // uses a global variable
      for(int i=0; i<users.length; i++){
        users.printUser();
public void printUsers(User[] users){
// preferred method - pass it the info it needs to do the job
for(int i=0; i<users.length; i++){
users[i].printUser();
public Test1(){
User u1 = new User("Tom", 20);
User u2 = new User("Dick", 42);
User u3 = new User("Harry", 69);
users = new User[3];
users[0] = u1;
users[1] = u2;
users[2] = u3;
printUsers();
printUsers(users);
public static void main(String[] args)
new Test1();
class User{
String firstName;
int age;
public User(String name, int age){
this.firstName = name;
this.age = age;
public void printUser(){
// here they are used as instance variables and not global variables
System.out.println(firstName + " Age: " + age);
Shit thats a lot of typing, and I'm not even sure I've explained it any good.
Hope you can make some sense out of this drivel.

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.

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.
-Parveen

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.
