Package Variable accessing...

Hi all,
When I try to access a packaged variable from frontend, Its giving a compile-time error :
Cannot directly access remote package variable or cursor
Why is it so? Is there any way to directly access them by means of some qualifier, etc.??
Its working fine when I try to do the same from SQL*Plus session.
Thanks

Package variables cannot be directly accessed from a Form, since it runs on the client, and your package is on the server. Each time your code checked or set a package variable, it would require a network round trip, and it wouldn't take much to ruin your response times.
The only way is to create a function or procedure in the package that you can call from the Form to set or retrieve the package variable values.

Accessing database package variables from Forms

I have a database package that populates a table of values, i.e.
type t_route_list is table of rt_route.RTR_ID%type;
route_list t_route_list
route_list gets populated by a package function and I want to access route_list in the Form.
While I can access other package variables by writing a function that returns the variable, Forms doesnt seem to like functions that return a user defined datatype as above. I have also tried using a procedure with an OUT param instead of a function but it also fails with same error.
i.e.
declare
v_route_list pkg_bulk_route_replace.t_route_list;
begin
pkg_bulk_route_replace.init;
pkg_bulk_route_replace.get_route_list(v_route_list);
message(v_route_list(1));
end;
This will not compile, but removing the index (1) from the last line makes it compile but crash with ORA-0600.
The code above with message replaced with dbms_out.put_line works fine on TOAD.
So my question is......
Can my database package return a plsql table to a form and if so, how?!

Actually I've got this to work now!
Thde main culprit appears to be a difference in the version of sql or pl/sql used on forms (version 5) and the database (8.1.7).
I had defined my table as a nested table. By redefining this as a indexed table, simply by adding on 'index by binary_integer' on my server package, I am suddenly able to access the elements of the table on my form. Fortunately this did not break the server code either - the table was populated using bulk collect and that still works.
Still got a bit of coding to do, but things are looking up now.

Accessing a packaged variable through db link

How do I access a packaged variable remotely? (Syntax)

You cannot do that:
SQL> conn xx/xx@xx

4 /
Package created.
SQL> conn yy/yy@yy
Connected.
SQL> desc p@yy

SQL> create synonym p1 for p@xx;
Synonym created.
SQL> desc p1;
SQL> begin
2    p1.a := 1;

Forms 9i accessing package variables

I created a package in my sql session which contains only variables. When I connect to the database through Oracle Forms and try to access these variables in a trigger I receive the error "Cannot directly access remote package variables or cursor" How can I access these variables from within a forms module?

You cannot access package variable or constants directly from a remote PL/SQL client. Only PL/SQL running on the server can access these. You need to implement get and set methods in the package.

ORA-20001: Unauthorized access (security group package variable not set).

I'm creating an app that uses APEX authentication and features self-registration (working) and forgot password (not working) forms.
My forgot password is public (requires no authentication). The user provides username and secret answer, which are validated, then provides the new password. I attempt to use htmldb_util.reset_pw to reset the user's password, but it's not working.
I have a process on the new password page calling a PL/SQL anonymous block that looks like this (see below), where P16_ITEM1 = username and P18_ITEM1 = new password.
BEGIN
apex_040000.htmldb_util.reset_pw( V('P16_ITEM1'), V('P18_ITEM1') );
END;
I also don't know how to send accurate success/failure messages from such PL/SQL block back to APEX, but that's a separate issue I guess.
Anyway, when testing via SQL Developer as the user with APEX_ADMINISTRATOR_ROLE, I get the following error:
ORA-20001: Unauthorized access (security group package variable not set).
ORA-06512: at "APEX_040000.WWV_FLOW_FND_USER_API", line 22
ORA-06512: at "APEX_040000.WWV_FLOW_FND_USER_API", line 1220
ORA-06512: at "APEX_040000.HTMLDB_UTIL", line 1253
ORA-06512: at line 8
I've searched previous threads and tried different suggestions with no luck.
I'm on Oracle DB XE 11g and APEX 4.x.
Any help will be appreciated. Thanks,
Alex.

Anyway, when testing via SQL Developer as the user with APEX_ADMINISTRATOR_ROLE, I get the following error:
ORA-20001: Unauthorized access (security group package variable not set).When running code outside Apex that depends on the Apex security group being set, run the following before your own code:
wwv_flow_api.set_security_group_id(apex_util.find_security_group_id('YOUR_SCHEMA_NAME'));Google "wwv_flow_api.set_security_group_id" for more details, such as this blog post:

How to get values from a stored package variable of type record ?

Sir,
In my JClient form, I need to get values from a database stored package variable of type record. And the values are retained in the JClient form for the whole session. The values are copied only once when the form is started.
What is the best way to do that ?
Thanks
Stephen

Stephen,
not sure what your model is, but if it is Business Components, I think I would expose the properties as a client method on the application module. This way all JClient panels and frames will have access to it. You could use a HashMap to store the data in teh app module.
If JDBC supports the record type, then you should be able to call it via a prepared SQL statement. If not, you may consider writing a PLSQL accessor to your stored procedure that returns something that can be handled.
Steve Muench provides the following examples on his blog page

Forms 10 and PL/SQL: Using a server package variable

Hi,
I have a variable created at package level in the server,
When I try to assign its value to a Forms item, I get an error.
"Unable to access distant package variable".
What should I do to access this variable?
Many thanks

Hello,
Add to the package a procedure to set this variable, and also a function that returns the variable content.

Global Variables Vs Form Library Package Variables Vs DB Package Variables

I realise this question has been asked a few times with varying degrees of answers, but I am still seeking comment/advice from others.
I am aware of following options for retaining persistent data to share between forms.
1. Package variables in a library that you share in a session.
This requires usage of SHARE_LIBRARY_DATA, there is risk that this not set, then does not share data.
2. Package variables in a database package.
Requires round trip to DB. Is this expensive for performance?
What about risk of DB package becoming invalid and losing state?
3. Use global variables
Can be tricky to manage.
4. Use parameters
Only one way, ie called form cannot alter value that caller can see.
Packages are closest to OO approach in using get and set modules. Allows all variables to be managed in one location. This appears best practice.
Forms library packages appear risky if caller does not include SHARE_LIBRARY_DATA.
DB packages have cost of round trip to DB. Does this become expensive is have to reference many times. Also topic of DB package becoming invalid and losing state?
Forms global variables have regular disadvantages of globals, ie not sure who may modify. Need to manage carefully. Text only
As a second related question, for value such as current user, for performance (and maintainability) is it better to obtain this from oracle user function each time, or save somewhere (in one of options above) and use that saved value each time.

My personal opinion:
I like the "packaged" version with getters and setters. In general, i create a client-side package in a pll which has methods to access the value by getters and setters. With that, the "implementation" is encapsulated and doesn't really matter to the rest of your system. All modules have to access the value using the getter and setter.
Inside the procedure i use two approaches:
1. If its for communication purposes between different forms i use globals, which are filled or extracted in the getter and setter (see this http://andreas.weiden.orcl.over-blog.de/article-28180655.html )
2. If its for someother purpose where the value should be "session persistent" i use a database package with getters and setters, which are called from the client-side package getter and setter. If the value is quite "constant" throughout the session, i read the value once at initialization code of the client-side package and the getter just returns that "cached" value
Hope this helps.

Package variables urgent

Hi,
I want to use certain variables which have been declared in the package ie global variables .
These variables are to be accessed in a trigger.
how do i do this.
any method is welcome,either through functions or procedures.
please do provide the solution

Thanks both for the reply.
Now the scenario has changed a bit.
what i have done is that i have defined a package variable in the package.
Now The package has 4 sps and i function.
I assign a value to the package variable in one of the sps.
using this value, I insert it into a temporary which i create inside the sp.(using execute immediate)
can i do this.i get an error of previalges which was sorted out.
Now i am accesiing the data in the temp table inside the function.the function returns me an id which is retrieved from another table using the value in the temp table.
This function is called inside a trigger,which gives me an error ora-04601-existing state of package being discarded.
pls help.

Package variable versus application context variables

Any difference in using package level variables versus setting attribute value pairs in a session based context ?
Thanks

Packaged variable - can be used only by user having execute privilege on the package. Same user can modify the values of the packaged variable when logged on to the session.
Context variable - It cannot be set by only mere value assignment, It needs to the call to a procedure(trusted program) to set the value, hence it is more secure.
Both are global variables & can be accessed throughout the session.
Regards,

Package variable

Can anyone tell me how to access package variables from forms6. When I tried to access, it says 'Implementation Restriction : '|variable name|' : Cannot directly access remote package variable '. Is there any other way to access these variables.
Thanks in advance,
Partha

Anton,
Thanks for your reply. And this is a very good idea. since I have so many variables to store in the package, I think I need to pass variable name also to the function. I am exploring this feature mainly to replace global variables in forms. could you tell me how best is this idea of replacing global variables in forms with package variables ? and also if you have any sample code using these package variables in forms, could you please send me that.
Thanks

Error trying to run SSIS Package via SQL Server Agent: DTExec: Could not set \Package.Variables[User::VarObjectDataSet].Properties[Value] value to System.Object

Situation:
SSIS Package designed in SQL Server 2012 - SQL Server Data Tools
Windows 7 - 64 bit.
The package (32 bit) extracts data from a SQL Server db to an Excel Output file, via an OLE DB connection.
It uses 3 package variables:
*) SQLCommand (String) to specify the SQL Statement to be executed by the package
Property path: \Package.Variables[User::ExcelOutputFile].Properties[Value]
Value: f:\Output Data.xls
*) EXCELOutputFIle (String) to specify path and filename of the Excel output file
Property path: \Package.Variables[User::SQLCommand].Properties[Value]
Value: select * from CartOrder
*) VarObjectDataSet (Object) to hold the data returned by SQL Server)
Property path: \Package.Variables[User::VarObjectDataSet].Properties[Value]
Value: System.Object
It consists out of 2 components:
*) Execute SQL Task: executes the SQL Statement passed on via a package variable. The resultng rows are stored in the package variable VarObjectDataSet
*) Script Task: creates the physical output file and iterates VarObjectDataSet to populate the Excel file.
Outcome and issue:The package runs perfectly fine both in SQL Server Data Tools itself and in DTEXECUI.
However, whenever I run it via SQL Server Agent (with 32 bit runtime option set), it returns the errror message below.
This package contains 3 package variables but the error stating that a package variable can not be set, pops up for the VarObjectDataSet only. This makes me wonder if it is uberhaupt possible to set the value of a package variable
of type Object.
Can anybody help me on this please ?

Hi Visakh,
thank you for your reply.
So, judging by your reply, not all package variables used inside a package need to be set a value for when run in DTEXEC ?
I already tried that but my package ended up in error (something to do with "... invocation ...." and that error is anything but clearly documented. Judging by the error message itself, it looks like it could be just about anything. that is why I asked my
first question about the object type package variable.
Now, I will remove it from the 'set values' list and try another go cracking the unclear error-message " ... invocation ...". Does an error message about " ... invocation ..." ring any bells, now that we are talking about it here ?
Thx in advance
Jurgen
Yes exactly
You need to set values only forthem which needs to be controlled from outside the package
Any variable which gets its value through expression set inside package or through a query inside execute sql task/script task can be ignored from DTExec
Ok I've seen the invocation error mostly inside script task. This may be because some error inside script written in script task. If it appeared after you removed the variable then it may because some reference of variable existing within script task.

Creation of developement class,package and access key

COULD ANYBODY EXPLAIN about
creation of developement class,package and access key
and who will create them?

Working With Development Objects
Any component of an application program that is stored as a separate unit in the R/3 Repository is called a development object or a Repository Object. In the SAP System, all development objects that logically belong together are assigned to the same development class.
Object Lists
In the Object Navigator, development objects are displayed in object lists, which contain all of the elements in a development class, a program, global class, or function group.
Object lists show not only a hierarchical overview of the development objects in a category, but also tell you how the objects are related to each other. The Object Navigator displays object lists as a tree.
The topmost node of an object list is the development class. From here, you can navigate right down to the lowest hierarchical level of objects. If you select an object from the tree structure that itself describes an object list, the system displays just the new object list.
For example:
Selecting an Object List in the Object Navigator
To select development objects, you use a selection list in the Object Navigator. This contains the following categories:
Category
Meaning
Application hierarchy
A list of all of the development classes in the SAP System. This list is arranged hierarchically by application components, component codes, and the development classes belonging to them
Development class
A list of all of the objects in the development class
Program
A list of all of the components in an ABAP program
Function group
A list of all of the function modules and their components that are defined within a function group
Class
A list of all of the components of a global class. It also lists the superclasses of the class, and all of the inherited and redefined methods of the current class.
Internet service
A list of all of the componentse of an Internet service:
Service description, themes, language resources, HTML templates and MIME objects.
When you choose an Internet service from the tree display, the Web Application Builder is started.
See also Integrating Internet Services.
Local objects
A list of all of the local private objects of a user.
Objects in this list belong to development class $TMP and are not transported. You can display both your own local private objects and those of other users. Local objects are used mostly for testing. If you want to transport a local object, you must assign it to another development class. For further information, refer to Changing Development Classes
http://help.sap.com/saphelp_46c/helpdata/en/d1/80194b454211d189710000e8322d00/content.htm
Creating the Main Package
Use
The main package is primarily a container for development objects that belong together, in that they share the same system, transport layer, and customer delivery status. However, you must store development objects in sub-packages, not in the main package itself.
Several main packages can be grouped together to form a structure package.
Prerequisites
You have the authorization for the activity L0 (All Functions) using the S_DEVELOP authorization object.
Procedure
You create each normal package in a similar procedure to the one described below. It can then be included as a sub-package in a main package.
To create a main package:
1.       Open the Package Builder initial screen (SE21 or SPACKAGE).
2.       In the Package field, enter a name for the package that complies with the tools Naming Conventions
Within SAP itself, the name must begin with a letter from A to S, or from U to X.
3.       Choose Create.
The system displays the Create Package dialog box.
4.       Enter the following package attributes:
Short Text
Application Component
From the component hierarchy of the SAP system, choose the abbreviation for the application component to which you want to assign the new package.
Software component
Select an entry. The software component describes a set of development objects that can only be delivered in a single unit. You should assign all the sub-packages of the main package to this software component.
Exception: Sub-packages that will not be delivered to customers must be assigned to the HOMEsoftware component.
Main Package
This checkbox appears only if you have the appropriate authorization (see Prerequisites).
To indicate that the package is a main package, check this box.
5.       Choose Save.
6.       In the dialog box that appears, assign a transport request.
Result
The Change package screen displays the attributes of the new package. To display the object list for the package in the Object Navigator as well, choose from the button bar.
You have created your main package and can now define a structure within it. Generally, you will continue by adding sub-packages to the main package. They themselves will contain the package elements you have assigned.

Hi all,
i have the following problem.
I have a form based on an interactive report.
all standard made out of the apex possibilities.
i have a number of validations, all automatically created by apex, in the form because of the not possible being null of certain columns in my database.
when i press the insert button or save button when i didn't fill in all the necessary fields, i get the following error:
ORA-20001: Package variable g_security_group_id must be set.
Error ERR-1023 Unable perform validations.
OK
i allready checked my validations and i can't find something wrong with it.
they haven't been modified neither after being automatically created by apex
anyone any clue?
thanks in advance,
Mr. T

Desmedt,
Can you please demonstrate this on apex.oracle.com?

Help needed for loss of package variables!

Seem to have an annoying problem which may just be a misundertanding about libraries.
I have two forms. Initially form 1 created initialised two package variables (of type ora_java.jobject) using the ora_java.new_global_ref function and these persisted across multiple user interactions and existed when form 2 was called (as new form / sharing libraries. Form 2 could call form 1 and the package variables still had values OK.
These package variables were placed in library which only contained this package and was attached to both forms.
I needed more functionality on form 2 so I created a menu module which had to run some code from form 2. I put most of the code (actually imported as it's mostly java classes) into the same library as the package containing the variables and attached the expanded pll to both forms and the menu module. Now when I run form 1 values for the package variables exist for the life of form 1 and form 2, but when I try to reference them after the initial display of form 2 they have disappeared!
Also if form 1 is called again then it behaves differently in that references to the variable are lost after the form is first displayed.
All forms and menus have shared libraries.
I have spent some time playing with different variables and it's the same regardless of the variable type.
Must be something to do with the library I think but don't know what - please help before I tear all my hair out!

Ian,
Ensure you have set the SHARE_LIBRARY_DATA parameter in your CALL_FORM statement.
Also deleting the .fmx files, disconnecting from the database and re-building the form usually helps when everything else fails and you have not made any other changes you can think of that may have caused it to break.
Also check that the forms are pointing to the right version of your .pll. Removing the attached library, adding it back and recompiling should do the trick.
Hope this helps, before you lose your hair!
