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,
Bart van der Heijden

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,
Amit

You 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;

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

Insert image to long raw column Oracle 9i PL/SQL

I am trying to insert a .jpg image into an Oracle 9i table datatype long raw. I am coding in PL/SQL. I have researched inserting images and all I get back is the cool dbms_lob utility info. I cant change the column type to a blob - the database is a people soft delivered table and I am not allowed to change it.
Has anyone done this?
Does anyone have sample code?
Pretty Please (I need any help I can get)

How to insert data from file into long raw field using utl_file?

I try to insert binary data from a file (under AIX 4.3.3) into a LONG
RAW field (Oracle 8.1.6).
First, I retrieve the data from the file like this:
DECLARE
FileHandle = UTL_FILE.FILE_TYPE;
myVariable LONG RAW;
FileHandle := UTL_FILE.FOPEN ;('prj/oracle/admin/MARTIJN/udump',
'MyFile.ATT', 'R');
UTL_FILE.GET_LINE (FileHandle, myVariable);
UTL_FILE.FCLOSE(FileHandle);
INSERT INTO myTable(DUMMYFIELD) VALUES(myVariable);
Where DUMMYFIELD of table myTable is of type LONG RAW.
The GET_LINE statement crashes on Oracle Error ORA-6502: Numeric of
Value error: hex to raw conversion error.
What do I do wrong?
Do I use the right method to retrieve information from a file and put
it into a long raw field, should I try it another way?
Any help greatly appreciated,
Martijn Rutte

Zarina,
To clarify your problem, you have a script node contaning your Matlab code. Are you then using the standard LV functions to load in your data from a file and pass it into the script node?

SQL Loader Problem : how to skip column using sql ldr

Hi,
My problme is like this.
In the data file i am getting some data and storing it in flat file format with ` as delimiter.
For example:
t1col1`t1col2`t1col3`t2col1`t2col2`t2col3`t2col4
There are two tables here i.e t1 having 3 columns and t2 having 4 column values.
But in the database i m having only 3 columns for t2 which corresponds to data of t2col3. Now in my control file can i use filler to skip this value in the datafile with the columnName mentioned.
So my basic question is can i get rid of some column value which is there in the datafile and its position is not known when it will come but its name is known and its name is not present in the actual database. Can it be done using keyword "filler".
Any help on this would be highly appreciated.
Eagerly waiting for your reply.

Sql Developer MSSql Migration, Online data move, image to long raw mapping

Hello,
my task is to migrate a MSSql Server Database to Oracle 10.2.0.4 with SQL Developer Version 2.1.1.64
and JTDS JDBC Driver oracle.sqldeveloper.thirdparty.drivers.sqlserver 11.1.1.58.17.
Capture, convert and online data move works except data mapping from MSSql image to Oracle long raw dataype.
I need to map MsSql image to oracle blob, to achieve online data move!
is Sql Developer online migration MsSql image to oracle long raw possible?
I know that long raw is outdated, but i'm dba and not responsible for the software part.
What options should i try? offline data move? can MS Bulk Copy Program export image data and SQL*Loader import into long raw?
Any experience or tipp?
Thanks
Michael

Hi user12132314 ,
I do not see any 'long raw' options on our current SQLServer 2005 data type mapping. (Raw is a separate 2000 byte data type).
The usual route for SQLDeveloper is to go to Blob.
Online - this is simple & automated.
Offline - this actually goes via hex output in bcp to sqlldr, read in as CLOB which is then encoded to blob. (This is automated)
(Online 'Copy to Oracle' option, right click on table, may be of use if advanced features not included in the select such as defaults are not required, it copies over a select * from table, including blobs)
To move you from blob to long raw after migration can be done (easily enough if Oracle database >=10g so the stream does not have to be in smaller 'chunks')
http://asktom.oracle.com/pls/asktom/f?p=100:11:3938270166267830::::P11_QUESTION_ID:702825000306
I can look into this if you want to go down this route.
Note however that long raw has drawbacks and blob is preferred, see
Oracle® Database SQL Language Reference
11g Release 2 (11.2)
Part Number E17118-04
Data Types
LONG Data Type
for example one restriction is:
A table can contain only one LONG column.

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.

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,

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,
Mike

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.

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 insert a pdf or jpeg image into a blob column of a table

How to insert a pdf or jpeg image into a blob column of a table

Hi,
Try This
Loading an image into a BLOB column and displaying it via OAS
The steps are as follows:
Step 1.
Create a table to store the blobs:
create table blobs
( id varchar2(255),
blob_col blob
Step 2.
Create a logical directory in the database to the physical file system:
create or replace directory MY_FILES as 'c:\images';
Step 3.
Create a procedure to load the blobs from the file system using the logical
directory. The gif "aria.gif" must exist in c:\images.
create or replace procedure insert_img as
f_lob bfile;
b_lob blob;
begin
insert into blobs values ( 'MyGif', empty_blob() )
return blob_col into b_lob;
f_lob := bfilename( 'MY_FILES', 'aria.gif' );
dbms_lob.fileopen(f_lob, dbms_lob.file_readonly);
dbms_lob.loadfromfile( b_lob, f_lob, dbms_lob.getlength(f_lob) );
dbms_lob.fileclose(f_lob);
commit;
end;
Step 4.
Create a procedure that is called via Oracle Application Server to display the
image.
create or replace procedure get_img as
vblob blob;
buffer raw(32000);
buffer_size integer := 32000;
offset integer := 1;
length number;
begin
owa_util.mime_header('image/gif');
select blob_col into vblob from blobs where id = 'MyGif';
length := dbms_lob.getlength(vblob);
while offset < length loop
dbms_lob.read(vblob, buffer_size, offset, buffer);
htp.prn(utl_raw.cast_to_varchar2(buffer));
offset := offset + buffer_size;
end loop;
exception
when others then
htp.p(sqlerrm);
end;
Step 5.
Use the PL/SQL cartridge to call the get_img procedure
OR
Create that procedure as a function and invoke it within your PL/SQL code to
place the images appropriately on your HTML page via the PL/SQL toolkit.
from a html form
1. Create an HTML form where the image field will be <input type="file">. You also
need the file MIME type .
2. Create a procedure receiving the form parameters. The file field will be a Varchar2
parameter, because you receive the image path not the image itself.
3. Insert the image file into table using "Create directory NAME as IMAGE_PATH" and
then use "Insert into TABLE (consecutive, BLOB_OBJECT, MIME_OBJECT) values (sequence.nextval,
EMPTY_BLOB(), 'GIF' or 'JPEG') returning BLOB_OBJECT, consecutive into variable_blob,
variable_consecutive.
4. Load the file into table using:
dbms_lob.loadfromfile(variable_blob, variable_file_name, dbms_lob.getlength(variable_file_name));
dbms_lob.fileclose(variable_file_name);
commit.

Problems with LONG RAW column

We have a LONG RAW column.
JDev mapped it to Raw and LONGVARBINARY as SQL type.
Reading data (even huge amounts) works alright, but when we try to insert or update we get:
Data size bigger than max size for this type
I did some reading on the internet and found that I had to stream data into JDBC which Raw apparently cannot handle.
So how can I solve this?
And please, don't just write "Create a domain". I tried. It's not that easy for me. It should be a bit more specific.
Thanks in advance!
Sascha

You not only have to create a Domain but also implement either BlobDomainInterface or one of it's subclassed interfaces.
See oracle.jbo.domain.BlobDomainInterface (source in bc4jdomorcl-src.zip) for an example of how various interface methods are implemented.
When a domain implements BlobDomainInterface, it's called during load/save Entity data to setup it's transaction context (if it needs to during load) and to save it's content into the db using the given transaction context.
These interfaces are written with the assumption that there's an oracle.sql.* class that knows how to use transaction to fetch data using SQL-locator objects. In this case I believe you will need to extend the domain from oracle.sql.RAW class.

Copying Long Raw Column Data to another table

hi everyone,
i am trying to Copy Long Raw Column Data to another table in the same schema. this is the situation
Table A (col1 number,col2 long raw) with 100 records
Table B (col1 number,col2 long raw) with 0 records
now i want to copy col2 of the table A into the column 2 of the table B. but long raw data cant be retrieved in a select statement so is there any specific procedure that will copy long raw data or there is any simple way.
i will be really grateful for anybody's help.
thanx

Restrict the LONG RAW Column with less than 32760 bytes in the SELECT

When i am trying to access a LONG RAW Dataype wchich has characters greter than 32760 bytes i am getting this error.
Error -6502: ORA-06502: PL/SQL: numeric or value error
I came to know that PL/SQL will only be able to access the first 32760 bytes of a LONG RAW. If we try to fetch a LONG RAW from the database into PL/SQL variable which exceeds the 32760 byte limit then we encountered the above error.
Can anyone tell to avoid this error can we write a query to restrict the output to get only those records which has LONG RAW length less than 32760 bytes.
Since we canot use utl_raw.length() in the Select Statement, is there any function to restrict the the records for less than 32760 Bytes only for LONG RAW datatype, so that i will not get any records for more than 32760 bytes and we will not get this error.
REquest you to please help.

Hi
we do not have an option of migrating the LONG RAW to BLOB or any kind of ALTER to the table.
We want to restrict the use of Records from the Table which has data for LONG RAW column less than 32760 bytes, so that we will not get the PL/SQL numberic Error
any function for LONG RAW that can be used in SQL like for varchar2 we can use
select length(NAME) < 100 from tb_emp+
i.e it will get records only which has NAME less than 100 characters.
