RAISING EXCEPTION AND SHOWING TO USERS IN FORM BASED ON STORED PROCEDURE

I have a form based on stored procedure.
I want to handle exceptions in the stored procedure and show it to users.
Here is what i want to do.
I have a sku# field in the form and i want to validate it(against the database
table) in the procedure before inserting into the database.
I want to give a message to users when the validation fails.
How is this possible with the forms based on stored procedure?
Can i use javascript to do the same?

Help: FORMS based on stored procedures

I am working on a FORM based on stored procedures. This particular FORM performs a query and generates say,
customer_name, item1_sale, item2_sale and sum of the item1_sale and item2_sale.
I'd like to know if there are ways that the query procedure returns to reference cursors that one with multiple records and one with the sums? The FORM will then be able to show rows of sales and the bottom row with show the sale totals.
Thank you in advance.
Jimmy

Francois,
I just tried another way of getting the totals. I manually created a data block and add two items tot_1 and tot_2. I the item properties: I set calculation:
calculation Mode: Summary
Summary Function: Sum
Sumary Block: BLOCK_A
Summary Item: item1_sale etc.,
I got a compile error:
FRM-30377: Summary item must reside in single-record block or in same block as summarized item.
Where do I catch this error?
Thanks.

Would like to create a file upload facility in a form based on stored procedure

Hello,
I would like to create a 'File Upload' in a 'form based on stored procedure'. The version of portal that I am running is 3.0.7.6.2. In this version, only 'form based on table' has the ability to upload files. Or is it that I am missing something?

Help: FRM-40505 for a FORM based on stored procedures

Hi,
I am working on a FORM based on stored procedures. When it performs a query, it actually returns record, but still comes with the message FRM-40505: ORACLE error: unable to perform query. Any recommendations on the possible coding area to check?
Thank you in advance.
Jimmy

Jimmy,
To base a block on a stored procedure is not a simple task because it depends on the .....
.... stored procedure !
If you do not provide much information (like the famous stored procedure), we could not do anything for you.
As much information you provide, as much chance we have to understand the problem.

Form Based on Stored Procedure

I have an application (STAR_PORTAL) that is owned by the 'STARS3' schema. I want to create a form based on a stored procedure. The procedure ('select_empname') is stored in a package ('star_portal') that is owned by the portal30 user. When I get to the point where I link the form to the procedure, it does not see it. I have tried granting execute on star_portal to public and stars3.

We will checkup this issue why you do not see the procedure (most probably because it is a packaged procedure).
Meanwhile, you can continue creating the form by typing in:-
portal30.star_portal.select_empname
where you need to specify the procedure name.

Adding fields to a form based on stored procedure

I have a store procedure and a form based on it. I'd added a new parameter to the store procedure. How can I do to add a field in the form which takes the new parameter. I'd tried adding a new field with the same name of the parameter but it didn't work.
Thanx

Hi,
It should work fine. What is the problem you are facing? Are you getting any error?
Thanks,

Problem passing OUT parameters form based on stored procedure to another form?

Hello,
I am unable to pass parameters of type OUT from a form based on a stored procedure to another form.
However, I am able to pass parameters of the type IN to the other form.
This is the code that I have under the heading
On successful submission of a form, execute this PL/SQL block or PL/SQL procedure:
declare
v_partno varchar2(100);
v_partdesc varchar2(200);
blk varchar2(10):='DEFAULT';
v_names varchar2(1000);
v_values varchar2(1000);
begin
v_partno:=p_session.get_value_as_varchar2
(p_block_name=>blk,p_attribute_name=>'A_PART_NO');
v_partdesc:=p_session.get_value_as_varchar2
(p_block_name=>blk,p_attribute_name=>'A_PART_DESC');
v_names := '_moduleid:_show_header:pnumber:pdescription';
v_values := '1325575336:YES:' || LTRIM(TO_CHAR(v_partno)) || ':' || LTRIM(TO_CHAR(v_partdesc)) ;
PORTAL.wwa_app_module.link (
p_arg_names => PORTAL.wwv_standard_util.string_to_table2(v_names),
p_arg_values => PORTAL.wwv_standard_util.string_to_table2(v_values));
end
Info:
1. Passing PART_NO (IN parameter) and PART_DESC (OUT paramter) to another form.
2. After hitting the submit button, the second form comes up, but with only the PART_NO(type IN) field completed. The PART_DESC(type OUT) field did not get passed to the second form.
3. The corresponding fields in the second form are pnumber & pdescription.
4. FYI - I can see all the OUT parameters correctly, if I don't try to pass control to the second form.
5. Portal 9.0.2 ( the version that ships with IAS 9.0.2)
Any help would be greatly appreciated. I have been stuck here for a while now!

Re: Error
Passing OUT parameter to another form.
You cannot retrieve the value of the OUT parameter from the session object because after executing your procedure,
the value passed out using the OUT parameter is not loaded in the session object.
But you can still achieve what you are trying in the following way.
Let's assume that your procedure has the following str :-
procedure proc1 (p_in in varchar2,
p_out out varchar2)
is
begin
/* your processing statements
end;
Say, the name of the field, in the 2nd form, where you need to pass the out parameter value is VALUE_FROM_OUT.
1> Edit the form on procedure proc1
2> Select the submit button in the left frame and for the PL/SQL button handler choose Submit action.
3> In the adjacent textarea, comment out the doSubmit statement and use code given below :-
declare
l_p_in varchar2(32767);
l_p_out varchar2(32767);
l_url varchar2(2000);
begin
l_p_in := p_session.get_value_as_varchar2(
p_block_name => 'DEFAULT',
p_attribute_name => 'A_P_IN');
execute immediate
'begin <schema>.proc1(:b_in,:b_out); end;'
using in l_p_in, out l_p_out;
l_url := 'http://<host>:<port>/pls/<dad>/<portal-schema>.wwa_app_module.link?p_arg_name=_moduleid&p_arg_values=<module_id>&p_arg_names=VALUE_FROM_OUT&p_arg_values='||
<portal-schema>.wwv_standard_util.url_encode(l_p_out);
<portal-schema>.wwa_app_module.set_target(l_url,'CALL');
end;
NOTE :
======
In the code given above, replace
<schema> with the schema name that owns the procedure proc1
<host> with webserver host
<port> with the port of your webserver
<dad> with the portal dad
<portal-schema> with the name of the portal-schema
<module_id> with the module of the 2nd form i.e. where you need to pass the value of the out variable.
You will have to grant execute privilege on procedure proc1 to your application schema,
if the procedure proc1 lies in a schema other than the application schema.
4> Finish editing the form.

How to verify the user information pass by the form with a stored procedure?

Hi,
I would like to know how to verify user information pass by the form with a stored procedure.
I want make a portal which accepts to new user registration, but I want verify the new user's informations (like the name don't contain a number etc).
Thanks for your help
regards
jla

Hi Samson,
You can use the UI API to do this. You can catch the form_ADD event and then validate the input from the users. You can even block the event from completing (and stop the document from being added) if your code finds some incorrect data using the bubbleEvent functionality.
I don't have one specific example to show you, but if you look at some of the SDK samples (for example C:\Program Files\SAP\SAP Business One SDK\Samples\COM UI\VB.NET\02.CatchingEvents) to see how to work with events, you can then create your own validation to ensure the users data is valid.

Calling a form based on a procedure from a report

I have a report and want the user to link to a form based on a stored procedure passing params from the report record. That I can do using the link option. But to complicate matters I have more than one form based on a procedure and depending on values in the reports data depends on which form will be called (passing values to the form (all based on stored procedures).
How can I do this ?
Any advice would be really appreciated.

If you want to display other HTML page after successful submission, you need to use
either go or call method.
I created a form on SCOTT.EMP and a report on SCOTT.EMP and the report accept a parameter for
the deptno. Here is my on successfull submission code:
declare
l_dept number;
l_url varchar2(2000);
begin
l_dept := p_session.get_value_as_number('DEFAULT', 'A_DEPTNO', 1);
l_url := 'scott.rpt_mask_1.show?p_arg_names=emp.deptno&p_arg_values='| |l_dept;
go(l_url);
end;

Return values for a Form based on a procedure

Hi,
I am fairly new to Portal Applications.
I have a form based on a procedure.
The procedure has an IN OUT parameter and what happens at the moment is that once the submit button is pressed the IN OUT parameter is displayed on a new page.
My question is...
How do I display the returned value in a field on the form?
Please help
Thanks

Hi,
This is how it works right now. It is not possible to show it in the same form.

How to display errror message in a form based on a procedure

I created a single-level form based on a procedure. In this form, I would like to generate an error message inside of a custom button, so I used the following inside of that button:
p_session.set_value (p_block_name => 'DEFAULT',
p_attribute_name => '_STATUS',
p_value => 'Please choose a valid chair from the popup icon.');
Unfortunately, it returned a WWV-0000 error code without any error messages. I use that code in another single-level form based on a table/view, and it works fine, but I need a single-level form based on a procedure. Therefore, I want to know if that code snippet can be used in a form based on a procedure or not? Do we have any other ways to display error messages in pl/sql besides p_session.set_value(...);
Thanks in advance.

Somebody please response.

Forms [32 Bit] Version 6.0.5.0.2 :: BLock based on stored procedure

Trying to develop a form having a block based
on stored procedure. My form works fine if
the stored procedure having REF CURSOR as one
of the argument but if I am using dynamic SQL
in my procedure I can not use Strong REF CURSOR, so I had to use Pl/Sql Table as one of the parameter in the proceudre.
In that case when I run my form and Execute the query it just comes out of the form without displaying anything and also it doesn't throw any error.
Don't know what I am doing wrong.
Pl. Help...

How to trigger and change password for AD user after form based login

Hello,
We are authenticating against Active Directory with Weblogic 10.3 using FORM based security. Everything is working. I need to now change a password for an authenticated user. For example, I have set a user to have their password expire on next logon from the AD side. The user logs in but somehow I need to trap some info from Active Directory (or an LDAP conversation) to figure out if I need to force the user to change password.
Do I need to start looking at custom code with LDAP Java SDK's or can I use a canned MBean from Weblogic Server.
I am looking at http://www.mozilla.org/directory/ for LDAP.
Can I set/reset an AD user's password with an MBean like the following link?
http://download.oracle.com/docs/cd/E13222_01/wls/docs92/javadocs/index.html?weblogic/management/security/authentication/UserPasswordEditorMBean.html
If anyone has any experience with this or can point me in the right direction let me know.
If anyone else is interested please add to the tread and I'll be sure to keep the found solution(s) updated here.
Thanks...........
