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!

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.

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.

Memory Leak with Oracle ODBC Driver for Long Raw columns

Oracle version : 8.1.7
Platform : Win2K
Oracle ODBC Driver version : 8.0.1.7.5.0.0
Hi,
I've got an Oracle database upgraded from
V8.0.5 to V8.1.7 which has a table having one long raw +
normal columns. I was able to observe distinct memory
leaks (approx 80K) when using ODBC interface calls (thro C++ code) that referenced a combination of normal & long raw columns in a select statement. However, this leak was not observed when only normal columns were present in the
select statement. Is there any known restriction for using
long raw columns with other columns? Or do long raw columns have a known memory leak problem thro ODBC?
Thanks!

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.

Problem with LONG FIELD

Hello,
In HTML DB, I would like to insert a line in a table with a database link (in a PL/SQL Block).
Description of my table :
Nom NULL ? Type
LCOMMENTID NOT NULL NUMBER(10)
DTLASTMODIF DATE
MEMCOMMENT LONG
TABLENAME VARCHAR2(18)
My command :
insert into amcomment@B_ASSET.WORLD values (1,'01/01/2005','toto','AMTICKET');
Each time I try to insert a value in the long field, I have this error :
"ORA-06550: Ligne 8, colonne 13 : PL/SQL: ORA-00600: code erreur interne, arguments : [qctstc2o1], [1], [0], [31], [8], [0], [0], [] ORA-06550: Ligne 8, colonne 1 : PL/SQL: SQL Statement ignored"
I try also with null value. Same problem ...
Have you a solution for this problem ?
Thanks.
FW

From the SQL Reference guide:
"LONG and LONG RAW columns cannot be used in distributed SQL statements"
It should also be noted that the LONG datatype has been deprecated and may not be supported in the future. It is suggested that LONG columns be replaced with CLOB columns. These are much easier to work with than LONGs and have fewer restrictions. You can easily use the TO_LOB function to convert a LONG to a CLOB (see http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96540/functions139a.htm#79466)

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
PROCEDURE pr_load_file

Getting the contents of a LONG RAW column

Hi, I'm using Oracle 8.1.7 with JDK 1.4.0, and I've got a dilemma. I have a table that has several columns, one column is a LONG RAW, the rest are just NUMBER or VARCHAR2. I need to transer the contents of particular rows to another table with the same structure. I've got a query the gets the correct rows, and I create and use a ResultSet to getInt(), getString(), and set the parameters of a PreparedStatement. Here's my problem, when I try to do a getBytes() on the LONG RAW column, it says "Stream already closed."
I was able to get around this in the past by just doing another query where the only column I selected was the LONG RAW column. Then it would let me do the getBytes(). Unfortunately, besides being inefficient, it is not possible to have 2 queries any longer. I was reading a little about this in the documentation, but I couldn't get a very good feel for it. Is there a way I can do one query and select all the rows, and still be able to pull out that data? Is there anything I'm missing? It seems like it's harder than it should be. Any advice? Thanks!
Tobin Juday

OK, I may have spoken too soon. I still seem to have the problem. Here's a chunk of my code, am I missing something dumb? Thank you...
resultSet1 = query1.getResultSet();
insert = conn.prepareStatement("INSERT....?,?,?)");
while (resultSet1.next())
insert.setBytes(23,resultSet1.getBytes("progtxt"));
insert.setInt(1, version);
insert.executeUpdate();
}

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;

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.

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.

LONG RAW Columns and Replication Set-up

we are working to set-up a replicated environment for all of
our Oracle Applications.
I could not get a clear understanding which Version Oracle will
support BLOB/CLOB/LONG RAW replication support or
Whether we can plan for Replicating such kind of Applications.
I read from one of Oracle Press book - "Oracle Backup &
Recovery" it is documented
that Oracle doesn't replication support for columns that use
BLOBs,CLOBs ( Page
no. 434 )
As one of our application was designed using LONG RAW Column, I
was wondering
about carrying the existing LONG RAW column to be replicated
like a CLOB/BLOB, if oracle supports Replication of BLOB/CLOB.
It will be of great help, if you can provide some insight in the
complexity of
having BLOBs in the applications to go further on making our
efforts to have a
Replicated environment set-up.
Thanking you in anticipation.

1) LONG and LONG RAW have been depricated since 8i so you shouldn't be using them ever for anything.
2) LONG and LONG RAW don't even have decent support to be manipulated from PL/SQL so there is essentially no SQL support.
3) It would be very rare that you would have anything to index in a LONG or a LONG RAW from a functionality standpoint. You're not likely, for example, to want to store more than 4k of data in a LONG and then do things like search for strings that start with a particular phrase. You're very very unlikely to want to search a binary LONG RAW to look for rows where the binary data starts with a particular string of bytes. You'd potentially want to be able to use Oracle Text on a LONG field to search for particular words and phrases in the text but I'm not sure that existed prior to LONGs being depricated.

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.

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.

My requirement is, i have to fetch and insert or update the record(Source and target table structure is same and dtabase is different).
Please suggest the best way of handle this problem.
Please let me know if you need more information.
