Updating record in a data block based on view in oracle forms

hi all ,
We have two data blocks in our custom oracle form.The first data block is for search criteria provided with buttons 'GO' and 'ADD ROW' and the second data block is based on a view that fetches record when user clicks on GO based on the the criteria specified in the above block. The Below block contains one SAVE button too.
We have a requirement when GO button is pressed and corresponding records are shown in the below block, user should be able to edit the record. Want to know how to make it editable?
Help appreciated....!!!

Your view is based on how many tables and does it include all NOT NULL fields from all tables?

We were able to do the same thing with Oracle Application Server and Oracle WebLogic Server. I cannot remember how different the processes were, but it seems like they were very similar. I am going to give you the instructions on how we implemented a "Read PDF" procedure on the WebLogic Server. If you are still on the Application Server you may have to do some Google searches, but it all boils down to the mod_plsql DAD Configuration file.
Our PDF was located in a table with the following structure:
CASE_DOCUMENTS
   (id_document                    NUMBER NOT NULL,
    doc_blob                       BLOB,
    note                           VARCHAR2(240),
    created_by                     VARCHAR2(20) NOT NULL,
    created_dt                     DATE NOT NULL,
    case_id                        NUMBER NOT NULL,
    filename                       VARCHAR2(100) NOT NULL)Based on that table structure we created a procedure named READ_PDF which you will reference below in the dads.conf file below:
CREATE or REPLACE procedure read_pdf (p_id_document IN number)
is
view_file     blob;
BEGIN
select doc_blob
    into view_file
    from case_documents
   where id_document = p_id_document;
OWA_UTIL.MIME_HEADER ('APPLICATION/PDF', FALSE);
HTP.P ('CONTENT-LENGTH: ' || DBMS_LOB.GETLENGTH (view_file));
OWA_UTIL.http_header_close;
WPG_DOCLOAD.download_file (view_file);
END;
GRANT EXECUTE ON read_pdf TO financial_user_role -- Name of role to execute
/Basically, you are passing in one parameter and that is the primary key for your table. You are selecting the pdf stored in a BLOB for that primary key. The commands below that allow the pdf to open up so you can view it – we got this off some search we did a few years ago.
Now, you need to add logic to your Oracle Form that will call the procedure above, but the URL is based on the dads.conf file that we will set up below… Anyway, we created a button on the form module with a label of "View". In the WHEN-BUTTON-PRESSED trigger the logic looks like this:
-- The View logic uses the DAD (Database Access Descriptors) method to view a .pdf file from the form.
-- The DAD was created on WebLogic Server with the name findadgen. This allows an http request be made
-- to the database.
declare
v_file          varchar2(400);
v_success       boolean;
ret_val         number;
v_http_link     varchar2(400);
begin
-- The format of the link is as follows: hostname:port/pls/DAD_name/procedure_name
v_http_link := 'http://finas03:8888/pls/findadgen/read_pdf?p_id_document=' || :case_documents.id_document;
web.show_document(v_http_link, '_BLANK');
end;The name of our WebLogic Server is "finas03" so that is what is listed in the URL. The "findadgen" is the name of the <Location> in the dads.conf file below, the "read_pdf" is the name of the procedure we created above, the "p_id_document=" is the IN parameter listed in the READ_PDF procedure created above, and the ":case_documents.id_document" is the reference to the primary key in our Oracle Form.
For WebLogic, you can either go through Enterprise Manager (directions below) or update the dads.conf file on the filesystem directly (if you update the dads.conf file directly then skip to step 4 and ignore step 5):
1.     Enterprise Manager -> Web Tier -> ohs1
2.     Oracle HTTP Server (pull-down) – Administration – Advance Configuration
3.     Select File – dads.conf
4.     Add something similar:
# ============================================================================
#                     mod_plsql DAD Configuration File
# ============================================================================
# 1. Please refer to dads.README for a description of this file
# ============================================================================
# Note: This file should typically be included in your plsql.conf file with
# the "include" directive.
# Hint: You can look at some sample DADs in the dads.README file
# ============================================================================
<Location /pls/findadgen>
    SetHandler pls_handler
    Order allow,deny
    Allow from All
    AllowOverride None
    PlsqlDatabaseUsername financial
    PlsqlDatabasePassword sdo_3#d1
    PlsqlDatabaseConnectString ffindbTNSFormat
    PlsqlNLSLanguage AMERICAN_AMERICA.WE8ISO8859P1
    PlsqlAuthenticationMode Basic
    PlsqlDefaultPage read_pdf
</Location>You are adding the <Location> section to your dads.conf file. The "finddadgen" is the name that you will reference in a change you fill make to your Oracle Form. The "financial" is the Schema, the "sdo_3#d1" is the password for that Schema, the "ffindb" is the database that the stored procedure is located on, and the "read_pdf" is a stored procedure you will have to create in order to read the pdf.
5.     Press the "Apply" Button
6.     Obfuscate the DAD password by running the dadTool.pl script located in $ORACLE_HOME/bin (This was done on Unix on our server with the following commands):
$> LD_LIBRARY_PATH=$ORACLE_HOME/lib;export LD_LIBRARY_PATH
$> cd $ORACLE_HOME/bin
$> perl dadTool.pl -f /u01/app/oracle/middleware/asinst_1/config/OHS/ohs1/mod_plsql/dads.conf
7.     Restart the Oracle HTTP Server using Fusion Middleware Control:
Enterprise Manager -> Web Tier -> ohs1
Oracle HTTP Server – Control – Shutdown
Oracle HTTP Server – Control – Start Up
If you followed the instructions above, you should have created a stored procedure, added logic to your Oracle form to reference that stored procedure, and created an entry in the dads.conf file. Once you move the form onto the server and you restart the HTTP Service, you should be able to view a pdf that is stored in a table directly from your Oracle Form.

Problem using views containing xpath expressions with Oracle Forms

Mark,
Nice to see you back on the forum answering questions.
This example is based on the standard purchaseorder schema.
i registered the schema, created a relational table and then created
a view using xpath.everything works well and i am able to select the data
using sql*plus. Now this views is like any other view, when i describe the
view, i can see the all the data types are valid for the columns and also the lengths.
Now when i try to base a data block in oracle forms using this view, i get error
"ORA-24324 - service handle not initialized."
Whereas if i create another view on top of the first view and then base the data block on this view, it works for me. i described the second view from sql*plus and everything seems to be same for me.
this is the same behaviour from database 9i r2 and it exists in 10g r1 also.
Any hints as what might be the problem or you would like me to file a tar for this.
create or replace view purchaseorder_header_xml
as
select id
       ,extractvalue(xml_data, '/PurchaseOrder/Reference') reference
       ,extractvalue(xml_data, '/PurchaseOrder/Requestor') requestor
       ,extractvalue(xml_data, '/PurchaseOrder/User')      po_user
       ,extractvalue(xml_data, '/PurchaseOrder/CostCenter') costcenter
       ,extractvalue(xml_data, '/PurchaseOrder/SpecialInstructions') spl_instructions
from tab_xmldata
create or replace view purchaseorder_header
as select * from purchaseorder_header_xml
/Raghu

Not used Forms for years. However I suspect that Forms is trying to poke around behind the view and not understanding what it sees. I expect you'll need to open a Forms Tar to get to the bottom of this. It also appears that you a workaround which is to create a view on the view by the sound of it..

Pls Help: View Crystal Report Via Oracle Form Builder

Hi!!
I want to know how to view the .rpt report (report made from Crystal Report) via Oracle Form Builder. I've to do it in my project. If you know, please tell me.
Thanks in advance,

I don't know how does crystal reports work, and I would guess you should ask the crystal guys to help you with this. find out if they have a command line interface that you can invoke from the host command in forms.

Viewing Icons in Oracle Forms on the Web - any solutions?

Has anyone had problems viewing icons when deploying forms on the web? In client server mode it used to be .ico files. I recently converted our files to .gif and added a register UI_ICON to recognize the icon images when running the forms. I still cannot get the images to appear (icons on buttons). Am I missing something? I am using Oracle Forms 6i Release 2 on Oracle9iAS (1.0.2.2.2a) platform.

The requirement to view online Oracle Form?

Hello there,
I am trying to view an online Oracle Form from an Oracle Form Server. As I know that, IE browsers with JVM support should be able to open the form and view it. But I am not so sure which version of the IE browser is able to do that. What I know is, with IE version 5 and above, it is able to do so. But how about IE 4 with JVM support? Is it able to do so?
Best Regards,
Candy

Passing a parameter to a view from an Oracle Form ?

Hello,
Can I create a view on the database which takes a in a parameter from an Oracle form.
If yes then what is the syntx , please let me know.
Thanks
IQ

There are ways to simulate a 'parameterized view'.
Create your view and have it reference some value in an application context (look up in the manuals "application context feature").
Then from your Form, just prior to selecting from the view, make sure you set the value in your sessions' application context.

How to view field name for a field in Oracle form?

I was told you can do this but I forgot how.
If you want to build a report, but don't know what the field name is in Oracle, you can open up the Oracle form and find the screen with that field name and do a trick that tells you the Oracle field name. Any help?

Getting Logged on User'Information in an Oracle-Form SSO Partner Application

Thanks in advanced. If you're writing your own partner application, then you are correct to get the user information from the output variables
from the parse_url_cookie procedure. You should then set the information you want to keep track of in the cookie, or combination
of cookie and persistent storage in the database. Take care of the security implications while doing this.
On subsequent calls to your application, the user info should be obtained from the cookie and the database, if you
are using a combination of the cookie and database storage to keep your info.
The owa_cookie.get routine is used to read the cookie, which is generated with owa_cookie.send.
These routines work fine, when invoked correctly.
If you are having trouble with them, you're probably not using the calls properly.
The following code provides an example of how to use the owa_cookie calls...
create or replace package testcookie
is
    procedure show (p_name IN VARCHAR2);
    procedure send
        p_name    IN VARCHAR2,

Oracle Spatial and Oracle Forms

Hi,
Does anyone have experience with Oracle Spatial and Oracle Forms?
I have generated a form, which is based on a view. The view uses the mdsys.sdo_relate operator. Somehow I am unable to get the form to perform (to get one record it takes over 20 minutes). While useing sql-navigator to process the same statement it seems no problem. The query that also uses the view, is then processed in 10 seconds.
I also noticed that when text-functions like ' lower' of ' upper' are used to query the view, the query is processed within 15 seconds. If I don't use ' lower' or ' upper' it takes a long time (> 20 minutes) to process the query. Is it possible that this causes the bad performance of the form?
On metalink I have found that forms and spatial do not cooperate because of the pl/sql version that
forms6 uses. There is no solution presented, does anyone know of a work around?
My configuration is:
Oracle 8.1.7 on WIN2K @ PIII-800Mhz 256 Mb memory.
Formsbuilder 6
If requested I can post the queries that I have made.
With regards,

How can I open a url in oracle form 9i without toolbar and menubar

I want to create a button in my form. When I click on the button it should open url without toolbar and menubar.
I tried with web.show_document. but I am not able to remove the toolbar and menubar. plus not able to specify width and height. Any way to achieve this.
Thanks,

Dear Frank,
I have done as follows
created a form with a button, and in my button pressed event I wrote
WEB.SHOW_DOCUMENT('javascript:openMyURL("http://192.168.1.34/HELP/ADMF0005.html");', '_Self');
and in my formsweb.cfg I have the following
HTMLbeforeForm=<script> function OpenMyURL(page){window.open(page,"myURL","width=700,width=400,top=0,left=0,toolbar=no,menubar=no"); } </script>
When I click on the button it is coming with toolbar , etc as well as no page found is coming with the following in the address bar.
