Populating vo from pl/sql procedure and display on the scren in edit mode.

I want to show data in the page through dynamic vo.For that we have created a vo .inside the VOImpl file I have over write the executeQuery() and inside this method set all the values of the corresponding attributes.but when I run the page no data is comming in the page.Can any body help me to solve the problem.

Please post your question on the JDeveloper forum since this is not related to JHeadstart.
I also recommend you use the ADF BC Tester on your app module to test your VO, that is easier than generating a web page to test it.

Creating page items from pl/sql procedure and using them on a page

I have a page containing 2 select lists (P21_DEPARTMENTS and P21_DATE). Originally I added them as items that were "select list with submits". The problem is that based on the clearance level of the currently logged on user I only wanted the P21_DEPARTMENTS to be a select list if the user was an administrator. If however the user is not an admin then I want the page to have a hidden form field called P21_DEPARTMENTS that stores the user's department and has a label item that has the department name.
There is also a report region that generates a table based on the department selected from the select list (if the user is an admin) or the value stored in the hidden form field if the user is not.
My problem is that I cannot have both those items on the same page and use the HTML built-in authentication to determine which item should be rendered because I need to use the same ID for both items so that the stored procedure in my report region doesn't break. HTML does not permit items to share the same ID.
I tried to circumvent the problem by creating a stored procedure that performs all of the item rendering in the procedure and uses "htp.p()" to output all of my HTML code. This solution would allow me to pass a parameter into the procedure informing me as to whether or not the user is an administrator. If the user is an administrator the procedure would use a conditional statement and render a select list. If not, the hidden form field and label option would be used instead.
I finally got the stored procedure working perfectly. Now I am encountering the most bizarre thing. Since the "select list with submit" was not working (I used the same code that gets generated when I created other items using htmlDB's GUI) I decided to use a JavaScript function instead that gets triggered by the onChange event. I send along the value that is currently selected in the select list and in the function I set:
location.href='http://www.myoraclesite.com/pls/htmldb/f?p=111:21:729740000000000000::NO::P21_DEPARTMENTS:1';
In theory this should work. The problem is that it doesn't. The page reloads and the P21_DEPARTMENTS select list is not pre-selected.
The only thing I can think of is that when htmlDB generates page items that you've created with it's own admin tool it assigns some internal guid or something as opposed to when someone tries to generate dynamic page items of their own from a pl/sql procedure it's like the application doesn't even know they exist.
Any help would be GREATLY appreciated.
My only other solution would be to create a totally separate page (one for admin and another for non-admin). I would really like to avoid this.
Thanks in advance.

I would love to be able to generate my menus and
various other items in my htmlDB applications in much
the same way I can using ASP, PHP and Cold Fusion.
Users should have the ability to write server-side
code wherever they feel like it. The way htmlDB works
right now I spend more time trying to figure out how
to create simple effects and generate simple
interfaces when I need to be building a portal. Ami - it's important to understand that HTML DB is not like other languages. Thus, trying to force concepts which are common in other languages into HTML DB will often result in more work.
It's definitely worth the time to go over the HTML DB 2-day Developer, which can be found here: http://www.oracle.com/technology/products/database/htmldb/pdf/B14377_01.pdf
I can build a portal using Classic ASP, C#, PHP or Cold
Fusion in like 1/10 of the time that it takes me to
build one using htmlDB. I understand that this is not
meant for the hard-core programmer but no web
programming application in today's day and age should
prevent experts from getting under the hood.And I can build a Portal in HTML DB in 1/10 the time it will take me to do it in any other language. It's like anything else - proficiency comes with practice and work.
As for getting under the hood, there is plenty of places you can do that with HTML DB. Keep in mind that HTML DB itself is an HTML DB application, so the limits on what you can build with HTML DB are virtually limitless.
Sorry for the vent there. After spending the last 2
days trying to figure out how to implement such a
straightforward thing and now being informed that it
can't be done kind of bugged me.I understand your frustration, as I've been there before. My rule for beginners is that if you are writing more than a line or two of code in the first week, you're doing something wrong. Stop, take a break, and then use the ample resources (including searching this forum) to help solve your problem. There are plenty of resources available for you to learn about HTML DB on the HTML DB home page: http://otn.oracle.com/htmldb
Good luck,

How to extract row_id from PL/SQL procedure and assign that to batch script

Hello Team,
I am stuck with a requirement, wherein I am running a batch script and within the batch script I am calling a procedure which inserts a record in a table (Including a column named l_id).
I need this generated l_id to be passed on as a variable to batch script after PL/SQL procedure completion. So that I can refer this same l_id to update the same record in the table again in the same batch script in the later part.
Looking for some suggestions!!!!
Thanks

Looking for some suggestions!!!!Don't do this using batch scripts. Batch scripts are very much inferior compared to stored PL/SQL code when it comes to managing databases processes and performing data crunching.
Why can't this be written entirely in PL/SQL? And execution managed from either DBMS_JOB or DBMS_SCHEDULER ? And before answering that, consider the following:
- what is the superior language, PL/SQL or shell script?
- what provides tighter integration with the database, PL/SQL or shell script?
- what provides proper security and access control, PL/SQL or shell script?
As you can call SQL*Plus from a shell script to run PL/SQL, you can call a shell script from PL/SQL instead to run external commands and processes.
Use the right tool for the job. And shell scripting is an excellent tool - but only when correctly used. Are you using it correctly? I strongly doubt that...

How to open report in the browser from PL/SQL procedure

Hi,
I need to call the report (with destype = SCREEN) from the PL/SQL procedure and display in the browser.
For Example: when I call P_call_report procedure in my Forms6i button or at sql*plus, the report output PDF/HTML should open in the Browser window.
Iam Using IE, report6i, forms 6i, Oracle 8.1.7, Windows OS
I tried using UTL_HTTP(' ') in a procedure. But when I execute the procedure at sql*plus it says Pl/sql procedure completed successfully message without opening report output in the browser window. If I copy the same url and paste it in the browser, it works.
Please let me know if there is any solution.
thanks alot.

I guess event driven publishing may work. But Iam not sure about the opening of the browser from inside the procedure.

Creating web service from pl/sql procedure

Hello.
I need to create a web service from pl/sql procedure and i chose JDeveloper for this implementation. I have wsdl, but I never created web services. So, I created web service with document/literal message format.
But I have several troubles:
1. All element names have lower case letters.
2. The SOAP envelope must begin from words soapenv:Envelope but i have soap:Envelope.
3. And operation name has tail like "Element".
I know bad way for implement 1 and 3 points. It's a modification of java_wsdl_mapping.xml and wsdl files. But if I want to add new method to my service all changes will be cleaned. It's not critical but inconvenient to support.
But for point 3 i have no ideas.
This task is very important for me. Can somebody help me?

Returing array from PL/SQL procedure

Hi,
I am trying to return array from PL/SQL procedure. Heres is the code. I am getting an error "OracleParameter.ArrayBindSize is invalid ".
Will anybody let me know what is wrong in following code. or does anybody have code to return PL/SQL array using VB.NET.
oCommand.CommandText = "MyPack.TestVarchar2"
oCommand.CommandType = CommandType.StoredProcedure
Dim id As Integer = 10
Dim deptname As String()
Dim oParam1 As Oracle.DataAccess.Client.OracleParameter = New Oracle.DataAccess.Client.OracleParameter("id", Oracle.DataAccess.Client.OracleDbType.Int32)
Dim oParam2 As Oracle.DataAccess.Client.OracleParameter = New Oracle.DataAccess.Client.OracleParameter("deptname", Oracle.DataAccess.Client.OracleDbType.Varchar2)

Thanks

Thanks Arnold for the reply..
Yes, I am trying to get result set in array which is unknow to me (No of rows return by the query). For the test I will pre-define the result set so that I will able to set ArrayBindSize.
I have read C# example but when I try to write it in VB.NET it gives me syntax error when I try to set the ArrayBindSize.
oParam.ArrayBindSize = new int[3]{15,23,13} // individual max size of 3 outputsWill you please let me know how to set ArrayBindSize (VB.NET) because I am new to this..
There is an example at otn "How to: Bind an Array to an ODP.NET Database Command" which does multiple INSERTs in one trip to database. This works fine. I need to do same for the SELECT statement which will return me multiple rows. I do not mean refCursor. If I use refCursor, it will make soft parse which I am trying to avoid using this Array techniq.
Thanks

PL/SQL Procedure and Java

Hi All,
I am working on a Data Warehousing Product and generating Web Reports.
These Web Reports are JSPs.
The basic architechture used for this is :
1. Get the inputs required for Report Generation through a Web GUI
2. Validate and Process (If Valid) the inputs so that it can be applied on the Data in the DB to fetch appropriate information.
3. The Data from the DB is retreived in the form of PL/SQL Procedures, which take the Processed information from Step 2 as Input and give the Output in the form of REF CURSORS.
Note: There are a many PL/SQL Procedures that are being executed, based on the configuration the Client has set. This configuration enables the Client to set the columns he wants to see in the Web Reports. This configuration is set before the Reports are run.
4. A call is made from Java to Oracle, each time a PL/SQL Procedure need to be executed. The REF CURSOR received as an Output from the PL/SQL Procedure is processed.
5. The next PL/SQL Procedure is called (if existing), else the Processed Data (from REF CURSOR Output) is displayed in the JSP as Web Reports.
The issue with above architechture is the PERFORMANCE.
I would like to know:
- The various ways in which data can be EFFICIENTLY & QUICKLY retrieved from PL/SQL Procedure in Java.
- Are there any APIs that improve the Java-Oracle Data Fetch Efficiency
- Is there any Java Framework available that can be used to increase the spped of Web Report generation.
- Do you suggest any changes in the above mentioned architechture, that make this work a Sweet Sixeen Year olg guy! ;)
- In general, any input that can increase the Speed of Web Report Generation.
Kindly let me know if I have not been clear at any point, so that I can re-explain the same more clearly.
And the most important thing, kindly scrap down your thoughts about the same.
Thanks a lot in advance for your VALUABLE INPUTS.

TTClasses interface for PL/SQL procedure and fetching its results

Hi experts,
I am using TimesTen Release 11.2.1.3.0;
I created a simple PL/SQL procedure as follows in timesten-
Command> create or replace procedure employee(eno in emp.empno%type) is
> e_name emp.ename%type;
> begin
> select ename into e_name from emp where emp.empno = eno;
> dbms_output.put_line(e_name);
> end;
> /
And then I call it through TTClasses as
TTCmd cmd, compilecmd;
compilecmd.Prepare(conn,"alter procedure employee compile;",status);
cmd.Prepare(conn,"begin employee(1020); end;",status);
cmd.Execute(..);
cmd.FetchNext(..);
Here fetchNext is returning an error -
[TimesTen][TimesTen 11.2.1.3.0 ODBC Driver]Invalid cursor state
*** ODBC Error/Warning = 24000, TimesTen Error/Warning = 0
*** Unable to fetch row for statement: <begin employee(1020); end;>.terminate called after throwing an instance of 'TTError'
Aborted
How can I run PL/SQL procedures/functions on TimesTen through TTClasses interface?
Any help or input would be of great value.
Thanks

The issue here is nothing to do with TTClasses. Your PL/SQL procedure executes a SELECT statement (that returns just one row) using an implicit cursor within the PL/SQL procedure and retrieves the value of the ename column into the PL/SQL variable. However it does not them do anything with that value such as pass it back to the caller...
Similarly, the TTClasses code executes a statement that it is expecting to create an ODBC level cursor 9which thsi PL/SQL invocation will not of course) and it is then trying to fetch from a cursor that does not exist.
I would recommend that you take a look at the TimesTen PL/SQL documentation (Oracle® TimesTen In-Memory Database PL/SQL Developer's Guide Release 11.2.1) and refer to the section on IN, OUT and IN/OUT parameters. This will show you how you can use OUT parameters to return values to the caller. This technique works fine for ODBC, JDBC and OCi programs but does not sadly currently work with TTClasses. TTClasses has not yet been enhanced to support OUT and INOUT parameters. Of course as you have the source code for TTClasses you could make the necessary modifications yourself.
I will open a bug requesting that TTClasses support OUT and INOUT parameters but in the meantime if you need this kind of capability you will need to either modify TTClasses yourself or switch to using a different API.

Redirect From PL/SQL Procedure

Hi
I hope this is a relatively straightforward question, but I am having trouble getting a page redirect to work from a PL/SQL procedure.
I call the following procedure:-
CREATE OR REPLACE PROCEDURE DOWNLOAD_FILE(p_id NUMBER) AS
v_mime VARCHAR2(200);
v_length NUMBER;
v_file_name VARCHAR2(2000);
lob_loc BLOB;
v_session VARCHAR2(100);
BEGIN
v_session := v('SESSION');
SELECT MIME_TYPE,
FILE_CONTENT,
FILE_NAME,
DBMS_LOB.GETLENGTH(FILE_CONTENT)
INTO v_mime,
lob_loc,
v_file_name,
v_length
FROM SRGSUP_UPLOADED_FILES
WHERE ID = p_id;
owa_util.mime_header(nvl(v_mime,'application/octet'),FALSE);
htp.p('Content-length: ' || v_length);
htp.p('Content-Disposition: attachment; filename="' || v_file_name || '"');
owa_util.http_header_close;
wpg_docload.download_file(lob_loc);
EXCEPTION
WHEN NO_DATA_FOUND THEN
htp.p('Location: f?p=107:30');
END DOWNLOAD_FILE;
From the following HTML Expression in column formatting of a report:-
#FILE_NAME#: [ <a href="#OWNER#.DOWNLOAD_FILE?p_id=#FILE_ID#">Download</a> ]
When the table SRGSUP_UPLOADED_FILES contains the relevant document the file download works perfectly. However, if there is no file present I wanted the page to redirect back to itself. Instead it goes to the login page.
Initially I thought it was losing the session details so I tried "htp.p('Location: f?p=107:30:'||v('SESSION'));" but this made no difference.
Any help would be appreciated.
Thanks

Sending message from PL/SQL procedure to form

Hello Friends,
How can I send messages from PL/SQL procedure to Form ?
Ultimate target is catching progress of PL/SQL procedure from
form. I heard about DBMS_PIPe but not sure,.
Adi

Hello,
Yeah , I got the solution using DBMS_PIPE function,I
followed following steps.
1. Pipe is created. see below procedure.
create or replace procedure proc_testpipe as
     v_pipe_integer          integer;
     v_pipe_message          integer;
begin
     v_pipe_integer := DBMS_PIPE.Create_Pipe('adipipe');
     dbms_pipe.pack_message('Hello Adinath Kamode,Message
     from Pipe');
     v_pipe_message := dbms_Pipe.Send_message('adipipe');
     end;
end;
2. then I created one Function which will obtain message from
Pipe and
will return value to form.
create or replace function proc_callpipe return varchar2 as
v_msg          integer;
v_rem          integer;
v_message          varchar2(500);
begin
v_msg:=dbms_pipe.receive_message('adipipe');
dbms_pipe.unpack_message(v_message);
dbms_pipe.purge('adipipe');
v_rem := dbms_pipe.remove_pipe('adipipe');
return(v_message);
end;
3. Last I called this function from form.
Cheers .. !
