HELP! Update Blob procedure

I have some ascii files being stored in our DB as blobs.
These files have been extracted and modified. I need to now write a procedure to have these "old" blobs updated and a status column set to 'NEW' for these.
Anyone have some guidance on this?

>
Is this more clear?

Not quite.
Did you use sqlloader initially to load the files?
     YES ----> do you have an ID column that you use to compare against the data to match the records..?
                      YES ----> load the data into a new temp table and merge results based on the id column
                                    for records which have "bad files" .. and update the column_name to "good file"
                       NO ----->You'll have to truncate the table and do a fresh load and have all "good files"A little test case would help... and if the solution does not work for your case, you need to say why?

Updating blob files

can somebody help me, can mysql update blob data fields? or is there another way to change data i blob columns/...

Hi,
I've done this before in Oracle so not sure about mysql.
In Oracle, we have to insert a row into the database with an empty BLOB using the empty_blob() function within Oracle.
Then its a matter of calling a select on the row for UPDATE and streaming the BLOB into the database.
eg.
String sql = "INSERT into TABLE values (a,empty_blob());
... execute sql
then select on the table like this
String sql = "Select BLOB from TABLE where id = a for UPDATE; (Where BLOB is your Blob column name)
execute sql and the BLOB value returned can be used
BLOB blob = (BLOB)rs.getBlob(1);
I had to cast from the java.sql.Blob type to the oracle.sql.BLOB type then get an output stream and stream your data in. I used a byte[] to do this.
I'm not sure how you would go about this in mysql but maybe I've pointed you in the right direction.
hope this helps

HELP WITH BLOB CRYPTING

HI Guys,
i can't get the dbms_crypto procedure to work correctly:
i've a table where i upload data via apex, all stored in a blob table of mine and the download proc as well to download file: i can't crypt the blob file.
my custom proc is triggered:
As you can see only update, such it doesn't crypt nothing ;-(
I've copied only the encrypt proc such the problem has to be similare for the other proc as well.
Probably the error is using the same blob as source as destination, however i can't fix this, and i think is possible to 'work' on the same blob.
Note that only for test purpose i have copied the blob from another col of the same table (BLOB_CONTENT_NON_CRYPT), so my col has data in it.
create or replace TRIGGER BI_BNFOWNFL BEFORE INSERT ON BNFOWNFL
FOR EACH ROW
DECLARE
B BLOB;
begin
IF INSERTING THEN
select "BNFOWNFL_SEQ".nextval into :NEW.ID from dual;
END IF;
IF UPDATING THEN
B:=:OLD.BLOB_CRYPTED;
P_ENCRYPT.encrypt_ssnBLOB(B);
:NEW.BLOB_CRYPTED:=B;
NULL;
END IF;
end;
MY PROC IS AS FOLLOWS:
PROCEDURE encrypt_ssnBLOB( p_ssn IN OUT NOCOPY BLOB);
PROCEDURE decrypt_ssnBLOB( p_ssn IN OUT NOCOPY BLOB);
G_KEY RAW(32) := UTL_I18N.STRING_TO_RAW( 'ZORRO', 'AL32UTF8' );
PROCEDURE encrypt_ssnBLOB( p_ssn IN OUT NOCOPY BLOB )
IS
BEGIN
dbms_crypto.encrypt
( dst => p_ssn,
src => p_ssn,
typ => DBMS_CRYPTO.DES_CBC_PKCS5,
key => G_KEY );
END encrypt_ssnBLOB;
Thanx a lot for help

Hi, Marcello, glad to hear - you got the process working, but after i reread your post ( if i understood you correctly ) - i have some doubts on your procedure - could you get the original documents by decrypting your encrypted documents successfully ?
The main problem with it in my opinion - you can't pass to the encrypt procedure the same lob locator for source and for destination. Docs says - the output lob will be overwritten and it will be indeed (http://download-uk.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_crypto.htm#sthref1552).
To demonstrate this i set up some examples - in the first part i encrypt using the same lob locator passed to the encrypt procedure, in the second i created a trigger which works properly ( i.e. the encrypted part can be decrypted again, the encryption part of trigger body can/should be placed in the procedure of course). Another issue - with assignment like A_LOB := :NEW.LOB_COLUMN within the trigge - on this way your new variable points to the same lob as :NEW.LOB_COLUMN and therefor can not be used as destination lob parameter for the encrypt procedure - that is why i used in my example DBMS_LOB.COPY procedure.

Problem Updating BLOB Data in DB

Hi, There,
I have a problem when updating BLOB data in database table. I am
using Oracle 8.1.6, JDK1.3.0., oracle thin driver.
I have a Handle object handle (javax.ejb.Handle), and I need to
save this object in DB. The table has 2 columns: column 1
is "PK" Varchar2(30) Primary Key, column 2 is "HANDLE" BLOB.
According to the documentation I found from Oracle, I first
initialize the blob column, and then get the BLOB locator.
However when I try to update the BLOB data by invoking
executeUpdate() method on OraclePreparedStatement ops, I always
get the returned int rowCount=0, which indicates that no rows
have been updated. (This is verified by trying to retrieve the
BLOB column value which results in SQLException: Exhausted
Resultset.)
Any suggestions what was wrong with the code? Thank you a lot in
advance!
Tom
Part of the code is listed below:
// If jSessionID is not found, create it
HttpSession session = request.getSession(true);
String jSessionID = session.getId();
//get the Hanlde object for MemberInfo bean
javax.ejb.Handle handle = memberValidate.validateMember(
memberID, "" );
oracle.sql.BLOB oracleBlob = null;
/* Get DB connection */
try
Connection conn = getDBConnection(); // with oracle thin driver
conn.setAutoCommit(false);
catch (NamingException ne)
System.out.println( "Failed to getDBConnection due to Naming
Exception" + ne.toString() );
return;
catch (SQLException sqle)
System.out.println( "Failed to getDBConnection due to SQL
Exception"+ sqle.toString() );
return;
try
pstmt=conn.prepareStatement("CREATE TABLE TOM1 (PK VARCHAR(30)
PRIMARY KEY, HANDLE BLOB NOT NULL)");
pstmt.execute();
pstmt=conn.prepareStatement("INSERT INTO TOM1 VALUES('ROW1',
EMPTY_BLOB())");
pstmt.executeUpdate();
pstmt=conn.prepareStatement("SELECT HANDLE FROM TOM1 WHERE
PK=? FOR UPDATE");
pstmt.setString(1, "ROW1");
ResultSet rset = pstmt.executeQuery();
if ( rset.next() )
// Get the LOB locator from the ResultSet
oracleBlob = ((OracleResultSet)rset).getBLOB("HANDLE");
OraclePreparedStatement ops = null;
ops = ( OraclePreparedStatement )
(conn.prepareStatement("UPDATE TOM1 SET HANDLE = ?
WHERE PK = ?"));
ops.setString( 2, jSessionID );
// using OutputStream to write object data
OutputStream oStream = oracleBlob.getBinaryOutputStream();
ObjectOutputStream outStream = new ObjectOutputStream
(oStream);
outStream.writeObject(handle); // handle is the Object to be
saved
outStream.close();
conn.commit();
conn.setAutoCommit(true);
ops.setBLOB( 1, oracleBlob );
int rowCount = ops.executeUpdate();
System.out.println("\n**** Rows affected: ");
System.out.println(ops.executeUpdate());
if (rowCount != 0)
// Commit the transaction:
System.out.println("\n**** conn.commit() OK...");
System.out.println("\n**** Handle saved in DB as Blob-type
OK...");
conn.commit();
conn.close();
else
System.out.println("\n**** ops.executeUpdate() == 0, Failed
to update DB");
conn.close();
return;
catch ( SQLException se )
se.printStackTrace();
return;
catch ( Exception e )
System.out.println(e.toString());
return;
System.out.println("\n**** DB update OK...");

Your iPhone's iOS must be same or newer than the one in backups. In your case it is older so you need to update your iPhone and then recover it with backup.

Error when updating blob column

Hello,
im using the SQL-Developer and i have problems with updating blob columns.
I'm getting the following error:
UPDATE "MED400_INSTALL"."AMEDN_INSURANCE_TEMPL" SET WHERE ROWID = 'AAM6j5ABGAAAADpAAJ' AND ORA_ROWSCN = '26019698898'
One error saving changes to table "MED400_INSTALL"."AMEDN_INSURANCE_TEMPL":
Row 15: ORA-01410: Ungültige ROWID
I'm updating different tables and different rows.
This error is not shown in all cases. I can update some rows but not all off them.
Is this a bug?
TIA

I made some further investigations and have some more results.
- the problem does not occur all the time
- the problem seems to occur in the following situation
- User A: updates the blob-field using the sql developer menu and commits (-> success)
- User B: updates the blob-field using the sql developer menu and tries to commit (-> error)
- the error stays until User B does a rollback, after the rollback user B can update the blob-field! and user A gets the error.
Here are some extracts of sql developer log. It shows that the same row can be updated in somes cases, in others cases you get an error. After a rollback the field can be updated successfully The rowid ist the same. ora_rowscn is different:
UPDATE "AZUBI2"."AMEDN_INSURANCE_TEMPL" SET WHERE ROWID = 'AAc6TTACEAAAAHQAAC' AND ORA_ROWSCN = '26087686991'
One error saving changes to table "AZUBI2"."AMEDN_INSURANCE_TEMPL":
Row 1: ORA-01410: Ungültige ROWID
Rollback Successful
UPDATE "AZUBI2"."AMEDN_INSURANCE_TEMPL" SET WHERE ROWID = 'AAc6TTACEAAAAHQAAC' AND ORA_ROWSCN = '26087687075'
Commit Successful
I could offer a dump where you can possibly reproduce this issue. Where can I send or upload it.

Updating Blob

I am trying to write a java program to update blob in db. I am reading binary from filer and trying to update the blob. So table that has payload I am saying
update A
payload = ?
where A.id = 1
But I am getting ORA-00900: invalid SQL statement error.
In java program I am setting BinaryStream. something like
String SQL = "udpate fp set payload = ? where id = " + s + " and length(raw_payload) > 0 ";
System.out.println(SQL);
// Prepare a Statement:
PreparedStatement stat= conn.prepareStatement(SQL);
// Execute
try {
File f = new File("blob_upd.dat");
BufferedInputStream b = new BufferedInputStream(new FileInputStream(f));
stat.setBinaryStream(1,b,(int)f.length());
System.out.println("Number of rows updated " + stat.executeQuery());
b.close();

In Photoshop CC, Help Updates shows no updates but ACR is 8.0

Im on Windows 8, 64 bit. I have tried clearing my AAM cache and that hasn't helped. I tried downloading a patcher but it only trys to install on PS CS6. FOr some reason it won't register that I need to update Camera Raw to 8.1. Any help would be greatly appreciated. Thank you very much.

I was able to update PS-CC to ACR 8.1 using the following method:
I have CS6 already installed and already updated to ACR 8.1.
Today the Adobe Application Manager seemed to update itself to the Creative Cloud manager so I used that to download and install the Try version of Photoshop CC.
Photoshop CC installs with ACR 8.0; however, if I do a Help / Updates… in PS CC I get the old Adobe Application Manager back, not the Creative Cloud app, and the AAM does find the ACR 8.1 update compatible with PS-CC as well as the CSXS Extensions 4 update for CC that the CC Manager installed for CS6 this morning,
So it seems that the older AAM knows how to update PS-CC and the newer CCM knows how to update the older PS-CS6.
