URGENT - Extract Image Files From Long Raw Column
Hi.
I have to extract image files (tif and wmf format) from "long raw" column and put them in a directory, using a PL/SQL procedure.
Can anyone help me.
Thanks
Well that is interesting, that ORA returns no records on Metalink. Anyway, that was for my own curiosity.
As you are on 10g, this is how I would write a long raw to a file if I had no choice:
1) create a gtt with a column of type blob
2) insert into the gtt the long raw column using the to_lob conversion function
3) you now have a lob!
4) open a binary file for writing using utl_file (binary mode was introduced in 10g)
4) use dbms_lob to read through the blob and write it in chunks to the file
You will have to do this row by row. It will be painfully excrutiatingly slow.
This is basically your only choice unless you have a OCI programmer to hand. In which case I would be getting them to write the C code to read the long raw column and write it to a file. This could then be compiled into a library and called as an external procedure from PL/SQL.

ORA-22835: buffer too small when trying to save pdf file in LONG RAW column
Hi,
I get "ORA-22835: Buffer too small for CLOB to CHAR or BLOB to RAW conversion (real : 125695, maximum : 2000)" when i trying to save a 120k pdf file in an Oracle Long Raw column using dotnet 4.0 and Entity FrameWork.
Dim db As New OracleEntities
Try
Dim myEntity = (From e In db.TEXTE _
Where e.TEXT_ID = txtTextId.Text _
Select e).Single
With myEntity
If txtTextypeId.Text <> "" Then
.TEXTYPE_ID = txtTextypeId.Text
Else
.TEXTYPE_ID = Nothing
End If
.TEXT_NUM = txtTextNum.Text
.TEXT_NAME = txtTextName.Text
.TEXT_DATE = dtTextDate.SelectedDate
If DocAdded Then
.TEXT_DOC = Document
ElseIf DocDeleted Then
.TEXT_DOC = Nothing
End If
End With
db.SaveChanges()
Document is an array of Byte and TEXT_DOC also (mapped to a long row column).
is it possible to increase the size of the buffer ? how may i do it ?
Thx in advance.
Regards.Using a custom UPDATE or INSERT stored procedure for LONG RAW column with
exceed-limit data may still get the following error.
"ORA-01460: unimplemented or unreasonable conversion requested".
One option is to use BLOB instead of LONG RAW in your table and regenerate your
data model from the table. Then using the default UPDATE or INSERT statement
(created by EF) should work.
The following will modify your LONG RAW column to BLOB column.
Disclaimers:
1. It's irreversible--you cannot modify BLOB back to LONG RAW.
2. I have not tried that when there are huge data in LONG RAW column.
So be careful.
alter table <your_table_name> modify <your_long_raw_type_column> blob; -
How to get image out from LONG RAW from the database
Dear fellow Oracle users
I have a table about 50,000 rows one of the the column is LONG RAW.. and we store image files within this column ... almost 99% is gif format.
Does anyone able to recommand a way to get ALL these images out of the database and save it into a directory. May be a batch process or may be some kind of tools?
Not all the rows consists of images (i.e some of the the long raw can be null for some row) .
Any sample codes are very much appreciated...(I am okay with PL/SQL , a little rusty with Java coding but okay to pick it up again...)
regards
IvanHi,
if u are using oracle forms than u can integrate Webutil with it, there are many function available within webutil to do this.

How to load image in Long Raw column?
Dear all,
I need to upload a jpg image to a Long Raw column in one of our tables. Is there a way or utility so that I can do this thru a PL/SQL code? Please help.
Regards,
AmitYou must not be using LONG data type. It has been deprecated. You must be using BLOB. Here is an extract from AskTom.com on how to load a file into BLOB field.
create table demo
( id int primary key,
theBlob blob
create or replace directory my_files as '/export/home/tkyte/public_html';
declare
l_blob blob;
l_bfile bfile;
begin
insert into demo values ( 1, empty_blob() )
returning theBlob into l_blob;
l_bfile := bfilename( 'MY_FILES', 'aria.gif' );
dbms_lob.fileopen( l_bfile );
dbms_lob.loadfromfile( l_blob, l_bfile,
dbms_lob.getlength( l_bfile ) );
dbms_lob.fileclose( l_bfile );
end;

Loading Images into LONG RAW column using SQL or PL/SQL
Hi!
I am trying to load images into a LONG RAW column. Can anybody tell me how to do this using SQL or PL/SQL. I do not want to use Forms to do this. And, I have a limitation using BLOBs.
Thanks in Advance,
Kotesh.You wrote that you cannot use a java class to insert a picture. We are working on a school project and HAVE to use java as a client and Oracle 7 as a server.
Can you tell us how this is to be done?
Thank you in advance,

Load image file into a LONG RAW column via SQL*Loader
Does anyone know how to load a image file into a LONG RAW column via SQL*Loader?
Thanks
-Hsing-Hua-Are you trying to import the image on the client into Oracle lite, or from the server end into the main oracle database for download to the client?
On our system images are loaded into the the oracle lite database (10g R1 at the moment) on the client (DELL X50 PDA's) into a BLOB (Not LONG RAW) column using Java (relatively standard functionality in Java) as this is what our application software is written in.
From the server end, we do not at the moment load images as such, but we do load the application software into the database for deployment of new versions to the clients (the DMC/DMS updates we have found very unreliable), and the technique should be the same for images. Again the file is imported into a BLOB column.
NOTE a column defined as BLOB on the main Oracle database appears as a LONG VARBINARY on the client Oracle lite database, but the synchronisation process handles the conversion with no problem.
To import into a BLOB column on the server try the following
1) you will need to create a DIRECTORY (CREATE DIRECTORY command) within the database, pointing at a directory on the database server (or accessible from it). This is needed for the file location.
CREATE OR REPLACE DIRECTORY PDA_FILE_UPLOAD AS '/pdaapps/jar/'
NOTE create directory needs to be run as SYSTEM
2) define your table to hold the image and other data. Our tables is
SQL> desc pda_applications
Name Null? Type
ID NOT NULL NUMBER(12)
PDAAT_CODE NOT NULL VARCHAR2(10)
VERSION NOT NULL NUMBER(5,2)
PART_NO NOT NULL NUMBER(3)
FILE_OBJECT BLOB
DEPLOY_APPLICATION_YN NOT NULL VARCHAR2(1)
3) copy the image (or in our case a .jar file) to the database server directory specified in step 1
4) the actual import is done using a DBMB_LOB procedure

I have to extract all files from a hard drive of a macbook pro that is no longer working. All I have to access the hard drive is a PC, is this possible, and if so how?
You could try Paragon HFS+ for Windows. That would allow you to read and write files from a Mac-formatted drive.

Batch process to generate thumbnail pictures from a long raw column
Hello,
I need to generate thumbnail pictures from already existing pictures. The existing pictures are stored in a long raw column, the option to convert to BLOB col is not possible at the moment so I'm stuck with long raws.
Is there an easy way to generate those new pictures? do I have to build a form to download the picture, resize it and then upload it to the db in a loop for 16,000 pictures?
Any ideas would be appreciated.
Thanks,Sarvan,
You can have MRP propose two lots of SFG2 based upon lot sizing. For instance, if you always will want SFG2 to have orders of 50 each, then one way to achieve this would be to set the 'maximum lot size' to 50. MRP1 Tab of the material master.
There are other lotsizing methodologies that may be better suited to your business requirements as well.

6i to 9i conversion OLE container stored in a LONG RAW column to BLOB
I need to automate the migration of data stored in a long raw column to a blob column. The objects were stored in the long raw column using an Oracle Forms 6i OLE container. There is also multiple object types stored in the column, ie (word, excel, images, but mostly pdf's). I have looked at the webutil package but cannot figure out how to read the long raw column since ole containers are obsolete in 9i. I have a lot of records that need migrating and need help.
Thanks,
J. Broome
[email protected]It doesn't appear that I am able to attach the PDF files. Can you supply your email (or I can supply mine) so I can send you the three files:
1.) A good PDF (manually extracted from our old application)
2.) Dump of the same PDF file (includes header/footer info)
3.) A partially fixed PDF file (but some of the pictures / pages are cut off - specifically pages 3,5,9,10,12,14)
The way that we have tried to fix the file (in example 3 above) is the following:
a.) Find the First Occurrence of "%PDF-"
b.) Find the Last Occurrence of "%%EOF"
c.) if the first "%PDF-" is found AND the last "%%EOF" is found, then
i.) Remove all data before the first %PDF-
ii.) Remove all data after the last %%EOF
Let me know if you need any other information.
Thanks,

Hello, I have a Mac computer with NVIDIA 750M dedicated graphics card and monitor EIZO but the problem was there when I was working with Windows and Acer monitor. When I open a file from Camera Raw in PS this is smaller than the screen so I double-click with the tool "hand" to fit on the screen, but the picture loses sharpness and becomes blurry. If you magnify the image even only slightly with the tool "zoom" the picture comes back clear. In Camera Raw instead is always sharp. I solve the problem by turning off the graphics card in PS but often use plugin that need the graphics card otherwise the processing time is much longer. I ask for help.

Can any 1 help me out of the above problem.
Thanks in advance.The import seems OK, but it also seems that no rows have been imported, maybe no tables. What is the result of :
SQL> select owner, table_name from dba_tables where table_name like '%INVOICE%';
BTW, is the name invoice_content or invoice_contents ?
If the query does not give result, then try to check the content of your dmp file

How to differentiate picture formats in LONG RAW column?
Hi,
I have a table with a long raw column that contains pictures. I would like to know for each row if the picture in the long raw column is in JPEG, TIFF, BMP, etc.
Does somebody have an idea on how to do this?
Thanks!
Matt1) You really shouldn't be using LONG or LONG RAW data types any longer. You should at least be using BLOB data types here.
2) When you designed the schema, there should have been columns (or other tables) to store metadata about the file, including the type of image a row stores.
3) Lacking any of this, you could write a program that fetches the data and determines whether it is a valid JPEG, then checks to see if it is a valid TIFF, etc. until it happens upon a file format that appears to work. Obviously, though, that is a relatively costly exercise. If that's what you're forced to do, I'd strongly encourage you to store that information in a (potentially new) column in the database so you only have to do it once.
