Blob (bfile)+ ole2

hello gurus
i would like to know how is possible within Oracle Forms (i am still using 6i) to retrieve a MS office document stored in an oracle DB and showing it using ole2 automation.
I miss just the step of retrieving from DB and loading it into memory or somewhere on the client filesystem, so let it be opened with the right MS office application (chosen with ole2)
My actual idea is to create a block based on the table that stores the blob (bfile) column, but i don't know how to store the blob (bfile) object in the forms application.. there is a particular object to use? or i must just load the key (or rowid) and then requering the table using it? and after loading the blob (bfile) from table, how can i convert it to be usable for ole2?
thanks in advance!

Using BLOB,BFILE

I want to know these two things
٭ How to use BLOB data type?
٭ How to use BFILE data type?

Apart from what Raford mentioned, you should also keep in mind about the security aspect of it.
Documents stored in db are more secured or can be made more secured.
When you use bfiles, they are stored in OS and thus can be deleted intentionally or by mistake.
Performance wise, they donot make much difference even though bfile have an overhead of going to file system to fetch the fiiles/information.

How to use Blob storage to office 365 sharepoint online library documents

Hello,
Considering that we cant uploade a file with size more than 250 MB and it is recommended using Remote
Blob Storage (RBS) if large files are supposed to store in SharePoint.
My question is, how to use RBS or Azure Blob storage to store files instead of SQL database.
What is the configuration or code i need to write to accomplished this where i would prefer if it can be done simply using some configuration.
any sample or tutorial would be great help.
Thanks,
Asjad

HI,
What we did, we deploy small Azure PaaS application what used Azure Blob Storage and table and then show it in Office365 SharePoint online trough iframe. This gives you flexibility to customimze the PaaS application and show the content at blog storage.
We tested this in SharePoint ONline multitenant and Dedicated plus in On Premise SharePoint with the custom code in separate IIS server published trough UAG to Internet. This allows you to save or replace your file server with Azure and small PaaS apps in
and show the content on SharePoint ONline trough Iframe.

How to poll a blob using db adapter, with outer joins condition

Hi All,
We are trying to poll tables which contain column types as long and blob, we are using relationships in adapter and kept outer joins. by this we got select distinct t1.document .....etc
distinct keyword cannot be used for blobs.
is there any way to poll these tables having blob column types with outer joins.
thanks a lot in advance,
RR

Hi,
Procedure will be an explicit Invoke not Polling. If you can alter you design such that your BPEL process instead of polling gets triggered by some external entity (Java, PL/SQL, Scheduler, another BPEL etc.), you can put the data fetching logic in the procedure and call this procedure from your BPEL process to get the data. And your BPEL process is called periodically at an interval by an external entity.
Also see if you can restrict the duplicate records at the database level itself. Polling, AFAIK, is limited in terms of customization and wouldn't be easy to customize. However, would like to learn a way if someone has.

Converting LOB into BFILE variable

Hi,
I created a table with a bfile column.
I wanted to use webutil to insert files located on the client into this bfile column... but unfortunately it seems this package only allows the insertion of blob...
No problem I was ready to modify the webutil code to answer my needs, but I didn't find any information on how converting a blob into a bfile variable...
I've read the book 'Application Developper's Guide - Large Objects (LOBs) Part No. A96591-01', I've seen it's possible to Load LOBs witht data from a BFILE but i've read nothing on the reverse operation.
Is it possible or not ?
And if yes how can I do that ?
Thanks in advance.
Paul-AndrÃ©

I expected a function that could directly load a bfile variable with the content of a lob variableThat will not be possible, since a BFILE datatype, by definition, is only a pointer to a file on a disk. It does not contain the actual contents of the file, only a pointer to the location on disk.
You should consider using a BLOB instead of using a BFILE since you will have added advantage of the data being backed up and recovered (if need be) along with the rest of the database.

How to use setCLOB with JDBC.

Hi,
from oracle jdbc document, i know how to use getClob method. but i wonder how to insert a new record included a clob field (setClob). but clob is an interface.
it seem that it can not be successful to use setclob directly.
my friend has a way : insert an empty clob into database, then seek this record, and update it with full info again.
please help me!
thank in advance.
wu jianhua.

A few ways:
1. Use the LOBs got from a ResultSet, for example,
Clob x = rs.getClob(1); //you get an oracle.sql.CLOB object
pstmt.setClob(1, x);
2. use oracle.sql.CLOB
public static CLOB empty_lob() throws SQLException;
creates an empty lob.
public static BLOB createTemporary(Connection conn, boolean isCached, int
duration);
creates temp lob.
Those methods create object of type oracle.sql.CLOB.
refer to Oracle jdbc doc for this.

How load File as Blob in Oracle Table?

How load File as BLOB in Oracle Table?

Ah so nice, a FAQ, by someone who can't use online resources!
Any explanation why Google is broken for you?
Here is the code I use to load a jpg.
procedure upd_portrait(p_person_id in number, p_file_name in varchar2) is
l_blob blob;
l_bfile bfile;
begin
update person
set portrait = empty_blob()
where id = p_person_id
returning portrait into l_blob;
l_bfile := bfilename('MY_IMAGES', p_file_name);
dbms_lob.fileopen(l_bfile);
dbms_lob.loadfromfile(l_blob, l_bfile, dbms_lob.getlength(l_bfile));
dbms_lob.fileclose(l_bfile);

BLOB, BFILE problems

We have tried different methods to get these data types to work in a PO8 environment. If we use the Oracle Navigator we can store and read blob data. When we try the same using JDBC 2.0 driver we can not get even the insert to work correctly. Has anyone ever been successful in getting it work. The samples of codes in many books don't seem to have been tested either because they don't work either!
For example, using the BFILE option (example given by Steve Bobowski)gave us a FILEOPEN exception ORA error 22285 (No directory exists or cannot open file). The directory and the file does exist and the user has the required permissions!
Any help?

How to Get a BLOB Field from JDBC Coding

Hi,
I have written the JDBC Code to get the field values from the Table.
There is a BLOB field in that table.
How to get the BLOB ? What is the return type we should use.
If it is Varchar then we can use rs.getString().
If it is BLOB then what is the return type?
Thanks in Advance

Blob.
You know, people like you really give me the urge to print out several hundred pages of Java API and smack them on their heads.

The JAR is already load by using CREATE JAVA RESOURCE ... or "loadjava -resolve –force -user p/p@SID –genmissing -jarasresource MyJar.jar"
