Yest we can store BLOB,CLOB

Hi,
it is possible to strore the BLOB , CLOB and BFILES IN THE ORACLE8 and above DATABASE.
For this you can take the help of the DBMS_LOB package.
regards,
khaleel

How do you propose to do that? You are limited to 255 bytes per cell in Excel. If you come up with a scheme to lay down blocks of data and some way to uniquely ID them, then yes, you can; but you have to overcome that 255 byte boundary per cell before you can do much.
A CLOB can be stored as a string, but once again... there is that max character boundary to overcome in Excel.

10g BLOB/CLOB can we store more than 4k in SQL

Dear Friends
I know we had issues with BLOB and CLOB storing more than 4k in Oracle 8i using SQL. Is it the same in 10g BLOB/CLOB can we store more than 4k in SQL?
Please help me with some documentationw which explains these aspects with CLOB and BLOB in 10g
Thanks
Farouk

Thanks for your help,
I understand we can store blobs more than 4k in 10g using DBMB_LOG but there is a constraint in 8i that using SQL u can store directly only 4k and using a bind variable in PL/SQL we can store upto 32K. Is that the same in 10g or can we store directly using sql more than 4k?
Thanks

Can't fetch clob and long in one select/query

I created a nightmare table containing numerous binary data types to test an application I was working on, and believe I have found an undocumented bug in Oracle's JDBC drivers that is preventing me from loading a CLOB and a LONG in a single SQL select statement. I can load the CLOB successfully, but attempting to call ResultSet.get...() for the LONG column always results in
java.sql.SQLException: Stream has already been closed
even when processing the columns in the order of the SELECT statement.
I have demonstrated this behaviour with version 9.2.0.3 of Oracle's JDBC drivers, running against Oracle 9.2.0.2.0.
The following Java example contains SQL code to create and populate a table containing a collection of nasty binary columns, and then Java code that demonstrates the problem.
I would really appreciate any workarounds that allow me to pull this data out of a single query.
import java.sql.*;
This class was developed to verify that you can't have a CLOB and a LONG column in the
same SQL select statement, and extract both values. Calling get...() for the LONG column
always causes 'java.sql.SQLException: Stream has already been closed'.
CREATE TABLE BINARY_COLS_TEST
PK INTEGER PRIMARY KEY NOT NULL,
CLOB_COL CLOB,
BLOB_COL BLOB,
RAW_COL RAW(100),
LONG_COL LONG
INSERT INTO BINARY_COLS_TEST (
PK,
CLOB_COL,
BLOB_COL,
RAW_COL,
LONG_COL
) VALUES (
1,
'-- clob value --',
HEXTORAW('01020304050607'),
HEXTORAW('01020304050607'),
'-- long value --'
public class JdbcLongTest
public static void main(String argv[])
throws Exception
Driver driver = (Driver)Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
DriverManager.registerDriver(driver);
Connection connection = DriverManager.getConnection(argv[0], argv[1], argv[2]);
Statement stmt = connection.createStatement();
ResultSet results = null;
try
String query = "SELECT pk, clob_col, blob_col, raw_col, long_col FROM binary_cols_test";
results = stmt.executeQuery(query);
while (results.next())
int pk = results.getInt(1);
System.out.println("Loaded int");
Clob clob = results.getClob(2);
// It doesn't work if you just close the ascii stream.
// clob.getAsciiStream().close();
String clobString = clob.getSubString(1, (int)clob.length());
System.out.println("Loaded CLOB");
// Streaming not strictly necessary for short values.
// Blob blob = results.getBlob(3);
byte blobData[] = results.getBytes(3);
System.out.println("Loaded BLOB");
byte rawData[] = results.getBytes(4);
System.out.println("Loaded RAW");
byte longData[] = results.getBytes(5);
System.out.println("Loaded LONG");
catch (SQLException e)
e.printStackTrace();
results.close();
stmt.close();
connection.close();
} // public class JdbcLongTest

The problem is that LONGs are not buffered but are read from the wire in the order defined. The problem is the same as
rs = stmt.executeQuery("select myLong, myNumber from tab");
while (rs.next()) {
int n = rs.getInt(2);
String s = rs.getString(1);
The above will fail for the same reason. When the statement is executed the LONG is not read immediately. It is buffered in the server waiting to be read. When getInt is called the driver reads the bytes of the LONG and throws them away so that it can get to the NUMBER and read it. Then when getString is called the LONG value is gone so you get an exception.
Similar problem here. When the query is executed the CLOB and BLOB locators are read from the wire, but the LONG is buffered in the server waiting to be read. When Clob.getString is called, it has to talk to the server to get the value of the CLOB, so it reads the LONG bytes from the wire and throws them away. That clears the connection so that it can ask the server for the CLOB bytes. When the code reads the LONG value, those bytes are gone so you get an exception.
This is a long standing restriction on using LONG and LONG RAW values and is a result of the network protocol. It is one of the reasons that Oracle deprecates LONGs and recommends using BLOBs and CLOBs instead.

ORA-22275 :invalid LOB locator specified error while loading BLOBs/CLOBS.

Hello All,
I am trying to load BLOB/CLOB data from a client oracle DB to the oracle db on our side,we are using ODI version 10.1.3.5.6,which reportedly has the issue of loading BLOB/CLOBS solved.I am using
The extraction fails in the loading stage when inserting data into the C$ table with the following error.
"22275:99999 :java.sql.BatchUpdateException:ORA-22275:Invalid LOB locator specified".
Kindly let me know how I can resolve this issue as the requirement to load this data is very urgent.
Thanks,
John

One alternate way can be done out of ODI as ODI is still not able to resolve this issue. You can trim these fields (CLOB/BLOB) and push this data as separate fields into ODI and at the reporting end you can again concatenate them.
May be this may solve your problem ....it solved mine.

Display BLOB/CLOB image data in OBIEE 11g

Dear Gurus,
I want to display employee profile picture in dashboard, the image data was saved as blob/clob image.
How to configure and display it in obiee?
Regards
JOE

Hi
Thanks for your quick response.
actually im not using EBS, im just using publisher with OBIEE 11g.
if explain step by step what you wrote first replay-
Let i have a table with one BLOB column.
1) first load blob data to my table
2) create data model from oracle publisher.
3) change the xdm file with above tagline , my xdm file is in below link-
C:\mw_bi_home\instances\instance1\bifoundation\OracleBIPresentationServicesComponent\coreapplication_obips1\catalog\SampleAppLite\root\shared\zia%2exdm
i don't know is that right step? because if i re-open the xdm file after change by your given tagline its shows error.
I will grateful to you please give me a little explanation which file i can put the following tagline.
_<fo:instream-foreign-object content-type="image/jpg"><xsl:value-of select=".//IMAGE_ELEMENT"/></fo:instream-foreign-object>_
Thanks again and waiting your feedback -

Losing NATIONAL CHARACTERS(blob- clob- table). unistr?

Hello!
I have a problem with national characters. My example is as follows:
1. A csv file is uploaded from disk to htmldb_application_files
2. This BLOB is then converted to CLOB with dbms_lob.converttoclob()
3. Data from this CLOB is copied to PL/SQL array.
4. From PL/SQL array to table in database.
The problem: Either data copied to table in database loses national characters (display strange characters instead of national), or if I set my national character set id as an argument of dbms_lob.converttoclob() function I have an error - says that file is inconvertible.
What is wrong? How can I solve my problem? Can unistr() help somewhere? Any ideas?
Tom

BLOB-- CLOB-- BLOB conversion reducing length of BLOB

Hi,
I am using the following BLOB-->CLOB and CLOB-->BLOB conversion functions :
CREATE OR REPLACE FUNCTION blob_to_clob (blob_in IN BLOB)
RETURN CLOB
AS
     v_clob CLOB;
     v_varchar RAW(32001);
     v_varchar1 VARCHAR2(32001);
     v_start     INTEGER := 1;
     v_buffer INTEGER := 32001;
BEGIN
     DBMS_LOB.CREATETEMPORARY(v_clob, TRUE);
     FOR i IN 1..CEIL(DBMS_LOB.GETLENGTH(blob_in) / v_buffer)
     LOOP
     DBMS_LOB.READ(blob_in,v_buffer,v_start,v_varchar);
DBMS_LOB.WRITEAPPEND(v_clob, utl_raw.length(v_varchar), v_varchar);
     v_start := v_start + v_buffer;
     END LOOP;
RETURN v_clob;
END blob_to_clob;
CREATE OR REPLACE FUNCTION clob_to_blob (clob_in IN CLOB)
RETURN BLOB
AS
     v_blob BLOB;
     v_varchar RAW(32001);
     v_varchar1 RAW(32001);
     v_start     INTEGER := 1;
     v_buffer INTEGER := 32001;
BEGIN
     DBMS_LOB.CREATETEMPORARY(v_blob, TRUE);
     FOR i IN 1..CEIL(DBMS_LOB.GETLENGTH(clob_in) / v_buffer)
     LOOP
     DBMS_LOB.READ(clob_in,v_buffer,v_start,v_varchar);
DBMS_LOB.WRITEAPPEND(v_blob, utl_raw.length(v_varchar), v_varchar);
          v_start := v_start + v_buffer;
     END LOOP;
RETURN v_blob;
END clob_to_blob;
I am using these functions to convert image files, stored as BLOB to CLOB for intermediate storage, and then converting them back to BLOB. In this process, I see a loss of information when the image is converted from CLOB to BLOB ...which is seen by using dbms_lob.getlength() .Using the following sql query:
select dbms_lob.getlength(file_body),
dbms_lob.getlength(blob_to_clob(file_body)),
     dbms_lob.getlength(clob_to_blob(blob_to_clob(file_body)))
from my_table where image_id in (8819)
i see that returned length is usually half in the 3rd column, i.e. for dbms_lob.getlength(clob_to_blob(blob_to_clob(file_body))). There is no change in length for 1st and 2nd columns. Could you please let me know why length is getting lost in the CLOB to BLOB conversion ? Thanks.

Thanks for replying.
This is required because we have to store images in ldt files using FNDLOAD, whiich only supports CLOB, not BLOB. I understand that images stored in binary formats should be stored in BLOB only, but I am exploring the possibility of converting BLOB format to CLOB and then back to BLOB without loss of information. Any pointers in this regard are appreciated. Thanks !

BLOB/CLOB field issue

Hi All,
We have a requirement where there are BLOB/CLOB fields in the database containing word documents/gifs/
pdf files which need to pulled in the report as attachments. The attachments then need to be opened using the
respective applications like MS word etc.
Please let me know if this is feasible and if Oracle BI EE supports BLOB/CLOB data types. Are there any projects
which have implemented similar requirements?
Thanks in advance
Regards,
Andy

This can be done, but might need lot of work. Have you taken a look at this, especially first one.

Basic doubt on BLOB/CLOB

In Oracle 10g, the max size for BLOB/CLOB is mentioned as 4GB.
If i store a binary file of size 2MB in a BLOB field, will it block the whole 4GB (4096MB) space for this. Or as like Varchar only the actual file size is used and leave the remaining 4094 MB as free.
Please clarify.

Could not resist it... here's a docu link to info about new LOB handling.

Handling BLOB & CLOB

Hi all,
Can anyone please tell me how to handle BLOB and CLOB using java? ie how to retrieve BLOB & CLOB data from the database?
Thanx in advance,
Regards,
Mani

Starting with version 1.2 the ResultSet interrface manages BLOB and CLOB types: you can use the following methods:
resultSet.getBlob(int i)
resultSet.getClob(int i)
This is what you needed?

How do I creat an app say games that I can store all my games under?

HOw can I creat a master app that I can store other apps in. For example creating a master app such as games that all games would be stored under?

Hold down on one of your games so that the apps start to shake. Drag and drop the game onto another one. Both will end up in a folder called Games.

Hi! I have a library of around 1000 songs on my iTunes, I recently synced my phone and all was lost, my partner has the same songs on hers with a different sign in, but not backed up anywhere, any suggestion on how I can store her tunes in my account ???

Hi! I have a library of around 1000 songs on my iTunes, I recently synced my phone and all was lost, my partner has the same songs on hers with a different sign in, but not backed up anywhere, any suggestion on how I can store her tunes in my account ??? Then sync them to mine? When I sign her phone into her account I get a message warning that if I sync the dogs on her phone will be replaced by the ones in the library! But as there are no songs there I'm reluctant to continue!!! Please help this non techi guy.!!!!!

Hello Solid Buck,
Thank you so much for providing the details about the duplicate song issue you are experiencing. It sounds like you would like to remove the duplicate songs that will not play on your iPhone, but when you connect it to iTunes, iTunes only shows you one copy of the song on your iPhone.
In this situation, I recommend deleting the individual songs that do not play directly from your iPhone. I found the steps to do this on page 61 of the iPhone User Guide (http://manuals.info.apple.com/en_US/iphone_user_guide.pdf):
Delete a song from iPhone: In Songs, swipe the song, then tap Delete.
Thank you for using Apple Support Communities.
Best,
Sheila M.

How can we handle CLOB in Universe and WebIntelligence

Hi,
Could you explain how can we handle CLOB in Universe and WebIntelligence?If we use CLOB in either of this,how is the Report performance ?Is the perfomance of report degraded? Appreciate your help.
Thanks,
Swapna

Hi,
There is no way around this, long texts are big chunks of data that have to be moved from the database to the webi report.
Depending on how many rows of data you retrieve this can become a problem in various spots.
1) network traffic (lots of data to move over the network).
2) webi report memory (lots of data that needs to be stored in memory to work with the data).
So you need to limit the query in either the number of rows being retrieved,
or in the size of the data that is retrieved per row.
Depending on your use of message text, you can limit long text object to a smaller number of characters.
(Universe, Parameters, Controls...)
Depending on your version of database and BO, the default of this value is 1000 or unrestricted.
It might be that you just need an idea of the message and can limit this to 100 chars or similar, which should help performance.
It is also possible that the text is always 'long' padded with spaces, in this case it can help to trim the message column in the universe already.
Good luck,
Marianne

How many days we can store the data in psa & ods ?

hi guru's
how many days we can store the data in psa & ods ?
Thanks & Regards.
Prabhakarreddy

Hi Prabhakarreddy,
As many days as you like:
In the PSA you can keep data as long as you like but you will need more and more disk-space. So its advisable to clean up from time to time.
Example:
PSA's from full loads Clean up in a weeks time,
PSA's from Deltas: Clean up after you are sure data is correct. (e.g. a month or 90 days)
Remember that you cannot do a reconstruction from dataloads of which you have deleted the PSA. If some thing is wrong you will have to do an Init again!
In ODS's you must keep data in order to keep your delta loads to cubes in order. Removing data will force you to do a new initial load.
Sometime companies delete old data form ODS's that is older than a certain period (e.g. more than 3 years old) by running a selective deletion. You will have to do an init again. But loads and activation may run faster and of course you gain on disk space.
