How to manipulate LOBS from Forms 6i

Having a LOB column, how do I get to extract the data in it using Forms 6i?
If I try to use the dbms_lob package, forms dies horribly when using a LOB locator in select

How to access images stored in database using forms

i have created a table which stores images in bfile type
i would like to access the images along with other data
stored in forms.iam not able to get the image using select statement.could anyone tell me the format using which i would be able to access the image.

in my impression, Oracle's samples store the BFILE images off line though if I did not remember wrong.
If you can create a form type form using form wizard based on that image table, then you may execute query to view the image. But SELECT ... INTO will not work for LOBs on form.
If off line in file system, you may try to READ_IMAGE_FILE().

DML on LOB objects in the web based forms/devl6i

hi,
I have to migrate and build a new forms
using devl6i in web architecture.
At present the application is using
Long Raw column and OLE container in Client/server mode.
How I can insert ,update and delete
the LOB/Long raw objects using the three
Tier architecture.
I havent came accross any standard document
from oracle to handle this problem.
Is this requirement so tough that Oracle is
trying to escape??
Thank you...

I was facing the same problem as you and all I found was the information that since OLE functionality is bound to MS Windows systems there is no way to activate OLE in Web Environment with Forms 6i.
Sorry.

Importing multiple jpeg files from local folder into database LOB column

I have to programatically save multiple pictures (jpeg) from the folder on my PC into Oracle table LOB column. I have to be able to choose local folder on my PC where are the pictures, and press button on Oracle Forms to save pictures in LOB column in database.
I'm using Forms 6i and Oracle 10g Rel2 database.
Is this possible with Oracle Forms or the only way to do that is to use create directory database command and use dbms_lob package which I shouldn't do, because Oracle database directory is not allowed to see my local folder.

As I said I don't know how to use object data type, I just given a shot as below. I know the following code has errors can you please correct it for me.

What's new in Forms 6.0

Hi all,
I have been using developer 2000, forms 5.0. I just want to know that what is the major difference between forms5.0 and 6.0.
Is there any book which takes a user from 5.0 to 6.0.
Also, I beleive forms 6.0 supports internet deployment. Is that means even if I donot use java or any other internet programming langauage, still I can post my forms application on the web.
Do help me
Thanks in advance
Nitin Jain

There are one or two differences, such as support for LOBs and also Syntax Colouring in the PL/SQL Editor. You certainly don't need a book to make the transition!

How to Get Blob data(In String Form) using OCCI

Hello frnds,
I am new to OCCI,so i hvnt that much of master in that side.
I have one problem while handling BLOb data.
How to convert binary form of SDO_GEOMETRY data into string format. I am able to convert data by using PLSQL block,but its take so much time to execute.So performance is the main issue.So if there is any API in OCCI which convert directly blob data into string format.
Thanx in advance for your support,
Nilesh.

Have you tried reading "http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28390/lobs.htm#BABDEGJD" ? This explains how you can read from BLOBs into a C vector (or C++ vector of chars).

Setting query datasource at runtime for FORM Datablock

Hello all,
we have below requirement -
the Form datablock is build on a customized table. we need to populate some of the fields of the form by writing a view which joins tables across variousl modules. the form data will be queried by giving po number in query find window. then the rest of the fields are entered from the form front end and saved to the DB Table. we want to query the new po numbers from the view from the query find window. where as the existing po numbers will be queried from the form datablock table only... for this i wrote the below pre_query trigger at datablock level.
declare
     po_num number;
BEGIN
:parameter.G_query_find := 'TRUE' ;
select count(*) into po_num from ICS_PO_IBOT_ICOT_REP where vendor_po_num = nvl(:QUERY_FIND.PO_NUMBER, vendor_po_num);
     if po_num > 0 then
COPY(:QUERY_FIND.PO_NUMBER, 'ICS_PO_IBOT_ICOT_REP.VENDOR_PO_NUM');
     else
set_block_property ('ICS_PO_IBOT_ICOT_REP', QUERY_DATA_SOURCE_NAME, '(select * from ICS_PO_IBOT_ICOT_REP_VIEW where

please suggest what am i missing?????????????????????
Thanks,
Sam

here are the answers to your questions-
How do you update record?
Do you have any ON-UPDATE, POST-UPDATE, PRE-UPDATE triggers on this block?
Do you have any database triggers on the table?
What is DML Data Target Type property of this block?
it was not required for me to write any ON-UPDATE, POST-UPDATE, PRE-UPDATE triggers on this block to update record. these are done or taken care off automatically. no database trigger is associated with the table. DML data target type is table.
also the block has Query data source type as Table only. and the query data source name is the db table ie ICS_PO_IBOT_ICOT_REP. so what u suggest now? if i simply click on new button and enter some data onto form and save it it is inserting record onto db table. so why cant it insert the record in current scenario when a new PO is queried from the view. Please help on this where i am missing.................

How to insert data from APEX form into two tables

Hi,
I'm running APEX 4.1 with Oracle XE 11g, having two tables CERTIFICATES and USER_FILES. Some of the (useless) fields are cut to reduce information:
CREATE TABLE CERTIFICATES
CERT_ID NUMBER NOT NULL ,
CERT_OWNER NUMBER NOT NULL ,
CERT_VENDOR NUMBER NOT NULL ,
CERT_NAME VARCHAR2 (128) ,
CERT_FILE NUMBER NOT NULL ,
) TABLESPACE CP_DATA
LOGGING;
ALTER TABLE CERTIFICATES
ADD CONSTRAINT CERTIFICATES_PK PRIMARY KEY ( CERT_ID ) ;
CREATE TABLE USER_FILES
FILE_ID NUMBER NOT NULL ,
FILENAME VARCHAR2 (128) ,
BLOB_CONTENT BLOB ,
MIMETYPE VARCHAR2 (32) ,
LAST_UPDATE_DATE DATE
) TABLESPACE CP_FILES
LOGGING
LOB ( BLOB_CONTENT ) STORE AS SECUREFILE
TABLESPACE CP_FILES
STORAGE (
PCTINCREASE 0
MINEXTENTS 1
MAXEXTENTS UNLIMITED
FREELISTS 1
BUFFER_POOL DEFAULT
RETENTION
ENABLE STORAGE IN ROW
NOCACHE
ALTER TABLE USER_FILES
ADD CONSTRAINT CERT_FILES_PK PRIMARY KEY ( FILE_ID ) ;
ALTER TABLE CERTIFICATES
ADD CONSTRAINT CERTIFICATES_USER_FILES_FK FOREIGN KEY
CERT_FILE
REFERENCES USER_FILES
FILE_ID
NOT DEFERRABLE
What I'm trying to do is to allow users to fill out all the certificate data and upload a file in an APEX form. Once submitted the file should be uploaded in the USER_FILES table and all the fields along with CERT_ID, which is the foreign key pointing to the file in the USER_FILES table to be populated to the CERTIFICATES table. APEX wizard forms are based on one table and I'm unable to build form on both tables.
That's why I've created a view (V_CERT_FILES) on both tables and using INSTEAD OF trigger to insert/update both tables. I've done this before and updating this kind of views works perfect. Here is where the problem comes, if I'm updating the view all the data is updated correctly, but if I'm inserting into the view all the fields are populated at CERTIFICATES table, but for USER_FILES only the fields FILE_ID and LAST_UPDATE_DATE are populated. The rest three regarding the LOB are missing: BLOB_CONTENT, FILENAME, MIMETYPE. There are no errors when running this from APEX, but If I try to insert into the view from SQLDeveloper, I got this error:
ORA-22816: unsupported feature with RETURNING clause
ORA-06512: at line 1
As far as I know RETURNING clause in not supported in INSTEAD of triggers, although I didn't have any RETURNING clauses in my trigger (body is below).
Now the interesting stuff, after long tracing I found why this is happening:
First, insert is executed and the BLOB along with all its properties are uploaded to wwv_flow_file_objects$.
Then the following insert is executed to populate all the fields except the BLOB and it's properties, rowid is RETURNED, but as we know RETURNING clause is not supported in INSTEAD OF triggers, that's why I got error:
PARSE ERROR #1918608720:len=266 dep=3 uid=48 oct=2 lid=48 tim=1324569863593494 err=22816
INSERT INTO "SVE". "V_CERT_FILES" ( "CERT_ID", "CERT_OWNER", "CERT_VENDOR", "CERT_NAME", "BLOB_CONTENT") VALUES (:B1 ,:B2 ,:B3 ,:B4, ,EMPTY_BLOB()) RETURNING ROWID INTO :O0
CLOSE #1918608720:c=0,e=11,dep=3,type=0,tim=1324569863593909
EXEC #1820672032:c=3000,e=3168,p=0,cr=2,cu=4,mis=0,r=0,dep=2,og=1,plh=0,tim=1324569863593969
ERROR #43:err=22816 tim=1324569863593993
CLOSE #1820672032:c=0,e=43,dep=2,type=1,tim=1324569863594167
Next my trigger gets in action, sequences are generated, CERTIFICATES table is populated and then USER_FILES, but only the FILE_ID and LAST_UPDATE_DATE.
Finally update is fired against my view (V_CERT_FILES), reading data from wwv_flow_files it populates BLOB_CONTENT, MIMETYPE and FILENAME fields at the specific rowid in V_CERT_FILES, the one returned from the insert at the beginning. Last, file is deleted from wwv_flow_files.
I'm using sequences for the primary keys, this is only the body of the INSTEAD OF trigger:
select user_files_seq.nextval into l_file_id from dual;
select certificates_seq.nextval into l_cert_id from dual;
insert into user_files (file_id, filename, blob_content, mimetype, last_update_date) values (l_file_id, :n.filename, :n.blob_content, :n.mimetype, sysdate);
insert into certificates (cert_id, cert_owner, cert_vendor, cert_name, cert_file) values (l_cert_id, :n.cert_owner, :n.cert_vendor, :n.cert_name, l_file_id);
I'm surprised that I wasn't able to find a valuable source of information regarding this problem, only MOS note about running SQLoader against view with CLOB column and INSTEAD OF trigger. The solution would be to ran it against base table, MOS ID 795956.1.
Maybe I'm missing something and that's why I decided to share my problem here. So my question is how do you create this kind of architecture, insert into two tables with a relation between them in APEX ? I read a lot in the Internet, some advices were for creating custom form with APEX API, create a custom ARP, create two ARP or create a PL/SQL procedure for handing the DML?
Thanks in advance.
Regards,
Sve

Thank you however I was wondering if there was an example available which uses EJB and persistence.

Show BLOB in Forms 6i

Hello:
I've got a table with a BLOB field.
I saved an image or another document using DBMS_LOB package.
Now I want to show it in a Form(6i).
I found this rutine but i don't know how show the blob field in a form.
Could anybody help me, please ?
Thanks.
DECLARE
ac BLOB;
amount BINARY_INTEGER;
offset INTEGER;
buf RAW(2000);
BEGIN
/* select the LOB from which to read and return the locator into 'ac' */
SELECT audio_clip INTO ac FROM multimedia_table WHERE id = 1;
/* open the LOB */
DBMS_LOB.OPEN(ac, DBMS_LOB.LOB_READONLY);
/* read the LOB value into 'buf' */
amount := 2000;
offset := 1;
DBMS_LOB.READ(ac, amount, offset, buf);
/* close the LOB */
DBMS_LOB.CLOSE(ac);
END;

You can directly use read_image_file built in to read an image from the clients system directly into a image object. And regarding form server crash, it is no where related to the form u are running. try to invoke forms runtime screen(which is available in forms installed software) and work with it.
And web.show_document cannot be used to open images from client side. As the form server will not recognise the clients file system.

How to get the identity claim encoding types of windows and forms authentication providers using API?

Hi,
We have to get all the claims providers associated with a web application and its identity claim encoding type using API.
For example:
If the identity claim of windows authentication is user name and the user name is a string, then we should get
"i:0#.w".
If the identity claim of forms authentication is
email and the provider name is "fba" , then we should get "i:0!.f|fba|".
The below link shows us to get all claims providers associated with a web application, but how do we get the identity claim encoding type of each provider?
http://msdn.microsoft.com/en-us/library/gg650432(v=office.14).aspx#SP_WCP_Tip3
using (SPSite theSite = new SPSite("http://someContosoUrl"))
// Get the web application.
    SPWebApplication wa = theSite.WebApplication;
    // Get the zone for the site.
    SPUrlZone theZone = theSite.Zone;
    // Get the settings that are associated with the zone.
    SPIisSettings theSettings = wa.GetIisSettingsWithFallback(theZone);
  // Get the list of authentication providers that are associated with the zone.
    foreach (SPAuthenticationProvider prov in
        theSettings.ClaimsAuthenticationProviders)
    {   // Need to get the identity claims encoding type using the SPAuthenticationProvider
Is windows authentication's identity claim encoding type always i.0#.w or the identity claim is always the user name?
Thanks & Regards,
Kalai.

If the requirement is to be able to convert claim identities to windows identities that can be used with other LOB/legacy application that still relies on NTLM/Windows Auth, then I would recommend to explore C2WTS.

Using a CLOB in Forms 6.0

I'm looking for information about the default functionality of Forms 6.0 when working with CLOB's. I have a table with one CLOB column (note field). I'm having some difficulty displaying existing data in a CLOB column. I am also having difficulty inserting and updating records from a form.
All existing records were first inserted using empty_clob(), and if the record was not updated then the form displays "##########".
How do I prevent this? How do I check from the form if there is anythting in the CLOB column other than the locator? Where do I put this code?
Were do you put the code for inserting and updating a record that has a clob column? It does not work directly in the form. I found information on the DBMS_LOB package does a procedure need to be used? On client or database. I was not able to use the dbms_lob package in form and database triggers.
Our users don't want to do anything but store and view the text in the clob.
Help please.
Thanks

Unless I and my development team are very much mistaken, we do not yet see ANY real, direct support for CLOB (or other LOB) datatypes in Designer/Developer Forms 6.0 or 6i.
We would like to be able to store & maintain large text stores (like form letters, etc.) in our database, and we do not want to use LONGs. As our dev. platform is exclusively Forms based, we have been forced to live within the Forms' CHAR(2000) datatype constraint limit in designing our targeted 8i db...
As the team's data architect, this seems absolutely ludicrous to me, but (given the fact we can only use Forms for the front-end), what other choice do we have???
I'd greatly appreciate hearing back from anyone in Oracle support or elsewhere who could categorically confirm or deny this de-facto constraint, and (if the latter), explain how CLOB manipulation / editing can be supported via either Forms 6.0 or 6i.
Thanks in advance.
