How to know thw document type in a blob data type

Hi
I'm creating a Picture resizer to resize all images in my Oracle Database Blob. Some records contain MS word document and not an image. Is it possible to know what is the type of the document save on the blob before I try to resize the image. I'm using VB.net 2005 and ODP.net connector.
Thanks in advance.

I would suggest keeping it simple. When storing the blob, store a type alnog with it to allow the manipulation of the data.
We use a single table to store and deploy application code (Jar files), sql script, signatures, word,excel and PDF documents and images. The file type makes it easy to use the correct viewr for the data or control the extract use of the data (as in running sql scripts/deploying jar apps)

Using a BLOB data type in a CMP Entity Bean: Error when send large files

I've successfully impleenting BLOB in my EJB. But the main prob is, it can only work on small file which is around 3K. Any larger files than that will caused error (refer below). I got info from a friend which is using normal JDBC call to insert a file into BLOB column that you can't use java.sql.Blob data type which will have this limitation. He suggested that by using oracle.sql.BLOB, this prob won't exist.
The problem is I'm unable to use oracle.sql.BLOB in my CMP EJB because in the jbosscmp-jdbc.xml, I'm able to specify the normal BLOB only which is java.sql.Blob (Refer below).
         <cmp-field>
            <field-name>attachment</field-name>
            <column-name>attch</column-name>
            <jdbc-type>BLOB</jdbc-type>
            <sql-type>BLOB</sql-type>
        </cmp-field>So, how do I solve this problem? I need to store files which the size is much bigger than that. I'm using JBoss 4 as my app server and Oracle 9i as my DB. I can see that there's many ppl facing this prob, but no solution to it. Pls advise. Thanks.

Pdf file stored as BLOB data type on Oracle

I store PDF file as BLOB data type on Oracle. There are cases
where I get multiple records from the database, that means I get
multiple PDF files. They have to be merged and displayed on the web
page. I tried CFContent which can display only one PDF file at a
time but not more than one, whereas cfdocument is having problem
converting binary data to string. I am kind of stuck.
Can you anybody please help me out? Please let me know if you
have any questions or this does not make sense to you.
Thank you in advance.

if by "merge" you mean 3 pdf into 1 pdf, try cfpdf (if on
cf8) or see this
thread if cf version less than 8:

BLOB data type. Will it be available in BO XIR4?

Hi,
Does any know if we will be able to use BLOB data type in the new coming release of BO?
Currently the only way you can use images is copying your image files physically to a folder because BO doesn't recognize BLOB data type from the database. Is there another way around this? Please share it!
Thanks,
Katia.

i dont think BO will support BLOB data

Tg4msql - Blob Data Type Support(Oracle 8i - sql server 2000)

hi,
We are trying to replicate the data from oracle 8i to sql server 2000 through tg4msql.if we want to replicate the data thet contains the blob field , we are getting invalid expression in the procedure marked with error line.
the procedure i am using is as follows
CREATE OR REPLACE PROCEDURE INSERT_SQL
AS
BEGIN
FOR VAL_CURSOR IN
--Get the Data from the table with status 0
SELECT rs_report_rowid FROM BIJU.rs_report where rs_report_status = 0
LOOP
for new_cursor in
--get the details of the record with the row id
select id ,name,DOB from biju.sample where rowid = val_cursor.rs_report_rowid
LOOP
---insert the data from oracle to sql where the oracle data type contains blob(here photo field data type is blob).
Error Line: insert into [email protected](id,name,photo) values(new_cursor.id,new_cursor.NAME,new_cursor.DOB);
END LOOP;
END LOOP;
COMMIT;
END;
i want to know that tg4msql won't support the blob data type on the oracle end?we configured blob eqivalent in sql server as binary.Any help or suggestion regarding this are welcome..
regards
Srini

Srini,
Support for LOB was added in v9.2. It is not supported in 8i.

Why need message type when u create data type...

why need message type when u create data type...

Hi,
A message type comprises a data type that describes the structure of a message. At the following points in SAP Exchange Infrastructure you can refer to the message to be exchanged at runtime by using the message type:
·        More than one message interface can use the same message type. For example, an asynchronous outbound message interface and an asynchronous inbound message interface can reference the same message type because the request message does not need to be mapped.
·        When defining a message mapping you can directly reference message types to map messages from an outbound interface to messages from a receiver interface.
For technical reasons, a data type is not sufficient to describe the instance of a message. In XML schema, data types are defined as abstract types that are not yet fixed to an element. You can only describe an instance of a message when you have specified a data type as an element type. Therefore, a message type defines the root element of a message.
A message type does not define the direction of the message exchange, in other words, whether it is a request or a response. In exceptional cases you can use the same message type for both the request and the response message.
A message type has the following characteristics:
·        It comprises exactly one data type, which determines the content of the message to be transferred.
·        It is identified by a name and an XML namespace. The name (together with the namespace) of a message type is located in the uppermost tag of the message to be exchanged. This is an element tag.
You have defined a message type GreetingRes that references a simple data type of type xsd:string. The XML namespace of the message type is http://sap.com/xi/myExample. The corresponding payload might look like this:
<?xml version="1.0" encoding="utf-8" ?>
<ns1:GreetingRes xmlns:ns1="http://sap.com/xi/myExample"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   Hello Mrs. Miller
</ns1:GreetingRes>
You can specify how a message type is used in more detail in the description
hope this will help you.

JDBC/RMI driver does not support BLOB data type

WLS 5.1 JDBC/RMI driver does not support BLOB data type. It is said in the Weblogic e-doc.
I am using DataSource for database connections, meaning JDBC/RMI driver is actually producing
database connections. I need several columns of BLOB types in my Oracle tables.
Should I use the "JTS" driver instead in order to have the BLOB types supported ?
Thanks for help.
[att1.html]

The error java.rmi.UnmarshalException seems to indicate you are somehow accessing the data-source over RMI, this seems odd. Are you running TopLink on a client and trying to connect to a WebLogic DataSource on the server?
Maybe try connecting directly to the DataSource without going through TopLink and see if you encounter the same issue.
You could also look at the TopLink WebLogic Examples and see how their configuration is different than your own.

BLOB Data Type

Hi
I have stored some images in my table using blob data type. Can anyone plz tell me how to fetch those images using oracle forms.
Thanks.

once you base you DataBlock in forms on this table with BLOB column you will automatically get an image item in the forms for this column.
rest is same as usual, when you do an execute query you should get the records.
but the images you have stored in the database should be as one of the following types.
BMP, CALS, GIF, JFIF, PICT, RAS, TIFF, TPIC.
set the appropriate value in the property of the Image item for the "Image Format" property.

Problem loading PostgreSQL Bytea data type to Oracle Raw data type

We are migrating our database from PostgreSQL to Oracle. First, we convert the BYTEA data type in PostgreSQL to Oracle RAW. The BYTEA data type is variable bytes array. How can we load the BYTEA data type to Oracle RAW data type? Or I have to convert to different data type. thanks.
Peter,

hi,
Instead of 'interval day to second' in method declaration use internal datatype 'DSINTERVAL_UNCONSTRAINED'.
There are more unconstrained types in oracle.
