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.

SSRS. Not passing fields/parameters to report when stored procedure keeps parameters inside IF statement

So what I mean:
I have stored procedure like this:
CREATE PROCEDURE sp_Example
@param1 NVARCHAR(20) = '',
@param2 DATE = ''
AS
BEGIN
IF (SELECT COUNT(*) FROM Table1 WHERE (Name = @param1 OR @param1 = '') AND (StartDate = @param2 OR @param2 = '')) > 2
BEGIN
SELECT Name, Date, Price, Etc
FROM Table2
WHERE (Name = @param1 OR @param1 = '') AND (StartDate = @param2 OR @param2 = '')
END
IF (SELECT COUNT(*) FROM Table1 WHERE (Name = @param1 OR @param1 = '') AND (StartDate = @param2 OR @param2 = '')) < 2
BEGIN
SELECT Name, Date, Price, Etc
FROM Table3
WHERE (Name = @param1 OR @param1 = '') AND (StartDate = @param2 OR @param2 = '')
END
END
So in stored procedure are some input parameters and they are passed into IF statement.
If I use this stored procedure as report's dataset (Microsoft Visual Studio 2013) in following:
Add
Dataset > Query
Type: Stored Procedure > sp_Example It
do NOT get any fields, but get parameters
If I use this stored procedure in following:
Add
Dataset > Query
Type: Text > EXECUTE
sp_Example It get all required fields, but do NOT get parameters
Of course If I add manually parameters or fields It not working.
If I change IF statement
in stored procedure something like:
IF (1 < 3)
BEGIN
SELECT Name, Date, Price, Etc
FROM Table3
WHERE (Name = @param1 OR @param1 = '') AND (StartDate = @param2 OR @param2 = '')
END
It normally working in report (getting all fields and parameters). So problem is that I pass parameters to IF statement.
Have you any ideas how to pass parameters to IF statement
and get It correctly working on report?

Hi Stanisolvas,
Per my understanding that you are experending some issue when using the stored procedure to create the dataset, you can't get the fields to display under the dataset, right?
I have tested on my local environment with the same script as your and can't reproduce the issue, Please try to check and provide more details information according to below points:
What do you mean of not get any fields, Is that mean no table header along with the value will display? If you got any error message, please provide it.
Did you use any temp table in the stored procedure, if so, the issue can be caused by the temp table you are using, please don't use temp table in it which will cause no fields display.
If you use the second method to execute the procedure, please check to make sure you have added the script like below to make the parameters display in the report:
exec sp_Example @Param1=@Param1,@Param2=@Param2
Please execute the stored procedure in the SQL Server Management Studio like below to see if the stored procedure will works fine:
exec sp_Example @Param1='Test1',@Param2='2014-10-15'
If this work fine in the management studio, please try to create an new report to re-add this procedure.
If you still have any problem, please feel free to ask.

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...

I drilled down the proble further and identified that i can
recreatr the problem in any 7.3.4 database ....
But in 8.0.5 it's working fine .....
Is developer 6.0 is going to support Oracle 7.3.4
it'll be highly appreciated if any one from Oracle development

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.

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.

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?

Block based on Stored Procedures & Locking_Mode

Hello,
I'm creating a block in Forms 6.0.8 based on Stored Procedures. I'm using the example given in Metalink doc 52778.1. Updates to data work fine if locking_mode = 'Immediate'. If I set locking_mode to 'Delayed' and run the form, when I try to update and commit something, then the IF condition in lock-procedure (grp_lock) always returns TRUE and I run into the exception trapped there. It appears that Forms is passing NEW values in p_grp_data if locking_mode is Delayed and this is causing the problem. Is there any thing I could do in the form or procedure (preferably in the procedure) to solve this problem ? I'm trying to write procedures that will work with both Immediate and Delayed locking_modes
thanks in advance..

Yes, I was hoping to use these procedures to map the collection type returned to the database to the block data. I guess I was wrong. Except for the initial query and reading some other information from the database, I don't have to use these procedures as I do not write anything to it.
Thank you for your help, I will go on from there.
So, it means that I will have to iterate through my collection inside Forms and manipulate my data row by row. Or, is there a way to pass an Oracle collection type between the database and the Forms client and have it displayed without having to iterate through the rows and mapping each field?

Pass date range parameter to SQL stored procedure.

Hi,
I'd like to pass a date range parameter from Crystal Reports to a sql stored procedure. Does anyone know if this is possible?
I've had no problem passing standard datetime (single value) paramaters to and from but am struggling with getting a range value parameter to work.
Environment: Crystal Reports 10/XI and SQL 2000 MSDE version or SQL 2005 Express Edition.
Any help would be appreciated.

Can someone please demonstrate exactly how to use formula results as date parameters to a SQL stored procedure? Keep in mind, there are two parameters to the stored procedure.
I have gleaned this much: Use Add Command and insert the procedure with
EXEC ServerName.dbo.usp_sprocName;1 '{?StringParameter}'
but if I try to do
{CALL ServerName.dbo.usp_SprocName({@Formula1},{@Formula2})}
then it gives the error "No value given for one or more required parameters".
Both of the parameters are VARCHAR(50).

This Microsoft site defines the format of the ODBC escape sequences, but I still do not know how to convince Crystal to insert it's parameter results or formula results.

Pass BLOB as parameter to Packaged Stored Procedure

Does JDBC (thin or otherwise) support passing a BLOB as a parameter to a packaged stored procedure in Oracle, or do we have to do an 'insert' statement to get it in?
All the articles I've seen seem to refer to insert and select, but I want to strictly enforce all access to the database being through a package rather than table level access.
We've certainly had no difficulty receiving blobs from the resultset returned by our packaged procedures.
Any help appreciated,
Thanks

Now, when I update a table field in the form and call the update stored procedure, this procedure takes the updated values in considerations, updates some more fields, and remove some records.
It is working as it should, except for two details :
1- I don't see the values updated by the procedure in the Form;
2- even though some records were removed from the table by the procedure, I still see all my records.
Is there a way to display the returned table?
And, is there any documentation about data block based on stored procedures, what are the required signatures and limitations of those stored procedures, what a lock procedure is supposed to do (mine does 'null;' ...), how to map a collection type defined in Oracle to a Form data block ? Any link will be appreciated, I have found half a dozen page vaguely detailing this on Google, but nothing that can compare to a usual Oracle manual. Maybe I have missed something.
Thank you for your help.

Passing Multi-Value Parameter to a Stored Procedure

Has anyone experienced passing a Parameter (MultiValue) to a Stored Procedure? I am aware that Crystal Passes the Param as an Array. How would you go about handling this within a Stored Procedure???

Hi Daniel
Try as below:
1. Create a Crystal report, and add a multi-value parameter.
2. Since the multi-value parameter is treated as an array, create a formula that uses the JOIN function. Create a formula as below:
//Formula: @JoinFormula
Join ({?Multi-value parameter array},";")
====================
NOTE:
In the formula above, a semi-colon (";") is the delimiter.
====================
3. Within the main report, create a subreport based on the stored procedure, and include the parameter to be populated with the multi-value list.
4. Link the Join formula in the main report to the stored procedure parameter in the subreport.
Doing so passes a multi-value parameter to the stored procedure.
Hope this helps!!!!

How to pass parameter from 1 stored procedure to another stored procedure inside crystal report

Hi
I have several stored procedure in my Crystal Report. I am wondering if it is possible for me to pass a parameter to one of the stored procedure and to use the result of that stored procedure E.g. CustomerCode. To another 2 stored procedure to generate the report dynamically?
I have 3 stored procedure
The 1st one is used to gather information and process the calculation
another 2 stored procedure is used for generate the graph and both of them required to take 2 parameters. The 1st stored procedure will require 1 parameter (E.G. Reference Code) and will return a set of information including the data that could be use on the other 2 stored procedures.
After I added these 2 stored procedure, it requires me to pass 3 parameters to the report. I would like to know if I could only pass the Reference Code for stored procedure 1 and use it to retrieve the information for the other 2 parameter?
Thanks in advance
Chi

Hi Chi
To pass parameter from 1 stored procedure to another stored procedure, you will have to create sub report. In your case you will have to create 2 sub reports for 2nd and 3rd stored procedure and link those sub reports with the main report using Reference Code field in order to pass the values.
After creating the report when you will refresh the report, it will ask 4 parameters, one parameter for main report, one for the first subreport and two for second subreport to fetch the data correctly.

Report based on stored procedure

I want to create a report based on stored procedure(not ref cursor!!!!!)
For example - Invoice report with data with complicated rules:
1.line - product_name and price
2.line - annual fee name and price
3.line - some special fee name and price
4..............
5..............
[b][b][b]Is it possible or not?
We can solve the problem using functions, i.e. select line_1_1(param),line_1_data2(param6) from dual union all and select line_2_1(param1,param2),line_2_2(sysdate) from dual and so on, but I am looking for better solution.
We also can use stored procedure to populate data into temporary table, run report and clear the data in the table after that, but database is read-only for users and we don't want to change the security roles.
Thanks in advance.

Data block based on stored procedure with input arguments

Hi,
I am able to create a data block based on stored procedure.
but I want that procedure to take input arguments as well and I am facing the issue while setting the value for that input arguments from another block item.
Please somebody help, How to set the value for input argument from another control block- item?.(Note :Data block is based on the stored procedure)
Thanks in Advance,
Anandan Muthukannan

I did exactly the same way you mentioned.
But while building the form, The call to the procedure in 'QUERY-PROCEDURE' trigger has been modified like this way
procedure_name(qp_data,':BLOCK.ITEM');
so in procedure i am getting the value as ':BLOCK.ITEM' not the expected value.
