How to move data of LONG RAW column to another table?

I want to transfer the Long Raw datatype from A ( a Long Raw) to B (b Long Raw) in PL/SQL. The data of a colum is bigger than 32KB
Pls help me to advise how to do that?
Thanks a lot for your reply.

Example:
begin
insert into a values(utl_raw.cast_to_raw(12345654));
commit;
for c in (select a from a) loop
insert into b values(c.a);
end loop;
commit;
end;

How to insert records with LONG RAW columns from one table to another

Does anybody know how to use subquery to insert records with columns of LONG RAW datatype from one table to another? Can I add a WHERE clause in the subquery statement? Thanks.

Insert into ... Select statements are not supported for long or long raw. You will have to either use PL/SQL or convert your long raw to blobs.

HOW TO RETRIEVE A LONG RAW COLUMN FROM A TABLE AND WRITE TO OS FILE

Good evening.
Please how can I read a long raw datatype from a table and insert into an operating system file using PL/SQL.
Thank you.

What does this have to do with LONG RAW? It is about UTL_FILE and not especially great code.
The question is how to retrieve and write LONG RAW and that is quite a different matter.
First you must convert it to BLOB.
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:13213885403654
Then you can write it out to the file system

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,

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 );

How to move data from one cell/sheet to another

Hi - Help! I have a spreadsheet with multiple columns & rows for ordering clothes. The first column is text of each item & it's size. What I want to do is:
IF D15 has a number in it, I want that number and the text from A15 to populate into another sheet.
Then I want to re-create this function in all the cells, so that if ANY cell has a number in it, that number and the text in the A column of that row shows up in the new sheet, in the corresponding cell.
here's a screen shot of my sheet:
Any help would be great!!
Kim

Hi Kim,
I got the same error message when building the formula—it's easy to get lost in all the parentheses!
Here's a breakdown of the formula I used.
=IF(OFFSET(Data :: $A$1,ROW()-1,COLUMN())>0,OFFSET(Data :: $A$1,ROW()-1,COLUMN())&" - "&OFFSET(Data :: $A$1,ROW()-1,0),"")
The overall stucture is an IF statement:
IF(test,"Yes","No")
IF(there is a value greater than zero in this cell's 'partner' on the main table,
(then) copy that value here and append the label in column A of the main table, separated by a space, a dash, and a second space,
(otherwise) put an empty text string here)
Test: OFFSET(Data :: $A$1,ROW()-1,COLUMN())>0
The 'partner' cell on the main table is the one on the same row and one column to the right of the cell containing the formula. (eg. for Summary::B2, the 'partner cell to be tested is Data::C2, the first data cell for Person 2)
OFFSET(base,r,c)>0 compares the value in the cell r rows below and c columns to the right of the base cell with the value zero.
Data::$A$1: A1 is my usual choice for the base cell, as it usually simplifies the calculations for r and c.
ROW()-1: ROW() returns the row number of the row in which it is located. In B2, it will return 2. '-1' reduces that value to 1, the row offset necessary to get from Data::A1 to Data::b2.
COLUMN(): COLUMN() returns the column number of the column in which it is located. In B2 it will return 2. No adjustment is necessary, as 2 is the column offset necessary to get from Data::A1 to Data::C2
OFFSET returns the value in Data::C2 and compares it with 0 (zero). The value (1) is greater than 0, so the test returns TRUE, and the IF function acts on the "yes" section.
Yes: OFFSET(Data :: $A$1,ROW()-1,COLUMN())&" - "&OFFSET(Data :: $A$1,ROW()-1,0)
This section contains two OFFSET statements.
The first is the same as the one in Test, and returns the value in the tested cell (1).
The second is the same, except for the third argument (c) which is fixed at 0 (zero). This returns the value in the cell in column A (zero columns to the right of A1) in the same row as the tested cell.
The two returned values are linked by this expression: &" - "&
"&" is the concatenation operator, which joins the values left and right of it into a text string. Here, the value returned by the first OFFSET (1) is joined to the text (space-space) contained between the double quotes, and that is joined to the value returned by the second OFFSET function (Item 1)
No: ""
If there is no number entered in the Data cell being tested, IF acts on the "no" section of the formula, and inserts an empty string ( "" ) in the cell containing the formula. An empty string displays as 'blank', and is the closest one can get to an 'empty' cell using a formula.
Regarding your questions:
"I seem to not understand what I'm supposed to put in the () and " " 's. I copied and pasted it and got the error message "the formula contains an invalid referance". DO i put certain row/cell numbers in somewhere?"
ROW() and COLUMN() should have no argument entered between the parentheses. Each returns the row or column number of the cell containing the formula.
The double quotes at the end of the IF statement define a text string with no text. You can put any text between them, but that text will then appear in all cells whose 'partner' cell does not contain a number greater than zero.
The 'invalid reference' error message usually means a formula is referencing a cell that is not on the table. My guess is that your Summary table includes a copy of column A from your Data table. That would place "Person 1" in column B on both tables, and would require an adjustment of 'COLUMN()' to 'COLUMN()-1' in the first two OFFSET functions.
Another possibility is a mismatch between the Data table name in the formula and the actual name of the Data table.
Beyond those possibilities, I'd need to see either the document or screen shots of both tables and a copy of the actual formula as you've entered it.

Barry

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

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;

Long Raw Column

Hi Everybody,
I am using Oracle 9i ver 9.1 & Developer 6. My requirement is to store documents in the database. For that I have created a Long RAW column in the table where I have to store that. On forms I have made an OLE Container whose OLE Class property is set to "Word.Document.8". When I run the form, everyting goes fine. I insert the record, with word documents, it saves. I cleared the form & when I query it gets back the document, ie I can open it by double clicking it. But, once I exit the screen, run it again & try to query, it fetches all other columns except the OLE container value. I mean when I query it after exiting once & running the screen again, it does not fetch that OLE container base table items value, which it displays if I query it, without exiting, ie, the time when I inserted the document in OLE container, saved it & cleared the screen.
Anyone having a work around pls, reply.
Thanks in Advance.
[email protected]

Hi,
Yes the data is getting saved. As, when i clear the screen & then query again it displays the data. At SQL promp, when i qureied the table, it displays on a single "D" as the column values for all the rows, whether I had inserted any value for that row or not. I mean it was displaying "D" in all the rows, though, I have not inserted value in all rows in the Long Raw Column.

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.

Updating a LONG RAW column

I have a table with a column of type LONG RAW that can take binary content of arbitrary length (up to 2 GB). I try to copy content from one row to another using the following SQL:
UPDATE TEAM_ADM.Content SET (Content, ContentType) =
(SELECT Content, ContentType FROM Content WHERE ContentId = in_SourceContentID)
WHERE ContentID = in_TargetContentID;
Content.Content is the column in question.
Oracle returns with error ORA-00997:
ORA-00997 illegal use of LONG datatype
Cause: A value of datatype LONG was used in a function or in a DISTINCT, WHERE, CONNECT BY, GROUP BY, or ORDER BY clause. A LONG value can only be used in a SELECT clause.
Action: Remove the LONG value from the function or clause.
Question: How can I copy a LONG RAW column from one row to another?
Regards,
Kjell Tangen

Hello,
It seems that the Long datatypes in Oracle have a lot of restrictions. According to
this blog:LONG and LONG RAW columns cannot be used in distributed SQL statements.
In that case, you should update the long raw column on the Oracle side. You can try to use openquery as Rick post above to send the SQL statment to Oracle and execute.

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!
Matt

1) 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.

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

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

LONG RAW and BLOB are very different data types. Oracle has been suggesting for quite a while that folks migrate from LONG RAW to BLOB-- it's much easier to work with BLOB data than LONG RAW data...
How much data, roughly, do you have in these columns. If it's relatively small, you may be able to use UTL_RAW.LENGTH. If it's longer, though, I believe you have to write a program that reads all the data and calculates the length as you go, which is obviously not particularly efficient...

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
