BLOB column not updating

i have two blob columns in my table say b1 and b2, that are used to store the images. the problem is, when i updates B1 column it works but as i try to update the B2 column only it the error 'ORA-100505 Oracle unable to update record' appears.
but if i updates both the columns then it accepts the value in B2 as well.
i am working with orcle 8i 6.1. i had faced this proble earlier agaisnt oracle 8, but as shifted to 8i the problem was solved, but it appeared again.
the other strange problem is,if the coloumn is blank and i call this any coloumn in report the rports aborts displaying message 'unable to read the image format', how ever it was working very much fine earlier. I tried to recreate the column but no success, i also used EMPTY_BLOB() to initialize the coloum but of no avail.
Any body could help please?
thanks in advance

BLOB column not updating using automated row processing

I have fiddled around with creating a simple application to understand how APEX handles images stored in blobs - did a simple app that stores them, gets them, displays them. it all works great.
so i have this existing table/application that i am trying to add a BLOB column to here's what i did:
it's a pretty simple form on a table with report application. just one table.
I added the BLOB to the table (and the other mimetype etc cols as well).
i added the page items to the form page.
i basically made everything identical in terms of page item settings and such to the working simple application.
so here's the problem... when i run the application and update a row, the BLOB column isn't updating. neither are the mimetype or filename columns. the activity date col is.
and here's another interesting thing. i quickly created another form and report pair on the same table, and when i ran it, it updates the blob col just fine.
why is my original form not updating it? what can i do to remedy this? any ideas? i've gone though setting by setting for the blob page item and the one that works is identical to the one that doesn't.
i'm using the automatic row processing to update the table.

Gary,
The DML processes (and the creation wizards for them) are for use with items having source type Database Column. If your page items don't use this source type, then neither the Automated Row Fetch nor the Automatic Row Processesing (DML) process types will work.

BLOB Columns Inserts/Updates ???

Please let me know how SQL*Loader can run updates to just the blob columns without truncation/replace. We want to do incremental updates to the BLOB column without truncation/replace. If this is not possible please let me know any other process which can do this with the best performance we have huge amount of data that needs to be processed. Please let me know .......
e-mail from the developer.
Is there something that we or the DBA’s can do to improve performance on these types of inserts/updates with blobs? Currently we are executing batches of inserts/update to the 5 IMAGE_* tables and those are triggering inserts into the IMAGE*_HISTORY tables

Full text search in BLOB columns NOT Working

Hi, I am using Oracle 9i.
Presently I use following code to create index.
begin
Ctx_Ddl.Drop_Preference ('text_only');
end;
begin
Ctx_Ddl.Create_Preference ( 'text_only', 'basic_lexer');
Ctx_Ddl.Set_Attribute ( 'text_only', 'index_text', 'true' );
Ctx_Ddl.Set_Attribute ( 'text_only', 'index_themes', 'false' );
end;
CREATE TABLE MY_XML_DOCS(
XML_RES_ID NUMBER (16) NOT NULL,
XML_RES BLOB NOT NULL,
XML_RES_PATH VARCHAR2 (128),
XML_DOCS_CREATED_BY VARCHAR2 (16) NOT NULL,
XML_DOCS_CREATED_DT DATE NOT NULL,
XML_DOCS_MODIFIED_BY VARCHAR2 (16),
XML_DOCS_MODIFIED_DT DATE ) ;
drop index FULL_TEXT_INDEX ;
create INDEX FULL_TEXT_INDEX ON MY_XML_DOCS(XML_RES)
INDEXTYPE IS ctxsys.CONTEXT
parameters ('lexer text_only stoplist ctxsys.empty_stoplist');
BEGIN
CTX_DDL.sync_index('FULL_TEXT_INDEX ','10M');
END;
And I've some XML documents stored in blob columns in the above table. But my query with 'contains' param does not return expected results.(it presently returns no results). Do I miss anything? Do I need to specify any thing else while I create the Index? Kindly advice.

I would agree the CLOB storage would be preferable for XML. If you are using BLOB storage, by default the documents are going to be FILTERed by the INSO_FILTERS. A BLOB column will give you reduced storage in a unicode environment though.
If you wish to store your data in a BLOB though, you should specify the NULL_FILTER in your create index statement to avoid having the INSO_FILTERS invoked.
Further, you may also require a CHARSET column in your table specifying the character set of your data for each row if it can vary. The Column should then also be specified in the 'PARAMETERS' clause of the create index statement, this way Oracle knows the correct character set to use when converting the binary data to character data.
My guess that you are not getting any query results because none of the documents are actually being indexed. Be sure to query the ctx_user_index_errors view to determine if you are getting errors at indexing time.

Audit columns not updated when update statement is invoked

I am trying to perform DML operation using "Process Row" process.
I have provided the default values for audit columns in the default section of the page item attributes.
When I insert, the record is inserted with proper default values.
The problem arises when I try to update the record. For e.g. the last_update_date is not update with the current timestamp. I tried using "After Submit -Computation". But the column is not updated with the current timestamp value.
I do not want to use database triggers.

What is the datatype of Last_update_date, DATE or TIMESTAMP or some variant of TIMESTAMP ?
Post your code and describe your computation point and conditions on it.

I really wonder why you do not want to use the better approach. Don't elaborate, I don't want to hear it.

How to update a BLOB column in a table with a file in local machine?

I have a file (of XML type) in my local machine. I want to update it in a BLOB column of a table in databse server. Can anyone help me in this regard. Appreciate your help.
Regards
Walter Nicholas

Can anyone help me in this regard.That's the client's job to read data on the client PC (from keyboard/mouse/scanner/file/whatever input) and submit that to the database server for processing and/or storage.
You cannot expect the server to hack into your PC and lift that data in the file from your disk. Not that is not technically possible. You can wire rockets onto a bicycle to make it go faster, but that's not a wise thing to do. Similarly, it is not a bright idea to ignore the very basics of client-server.
Bottom line - you need client s/w on your PC to load the content of that file into Oracle. It can be done using SQL*Loader as already suggested. It can be done using a web browser (submitting it via HTTP to web-enabled PL/SQL code). You can use FTP or WebDav and upload into Oracle's XDB (XML database).
Your requirements will determine what client to use. Once off load? SQL*Loader is very easy to use for loading XML files into the database.

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.

The workflow could not update the item, possibly because one or more columns for the item require a different type of information. Outcome: Unknown Error

Received this error (The workflow could not update the item, possibly because one or more columns for the item require a different type of information.) recently on a workflow that was
working fine and no changes were made to the workflow.
I have tried a few suggestions, i.e. adding a pause before any ‘Update’ action (which didn’t help because the workflow past this action without incident); checked the data type being written
to the fields (the correct data types are being written); and we even checked the list schema to ensure the list names and the internal names are aligned (they
are), but we still cannot figure out why the workflow is still throwing this error.
We located the area within the workflow step where it is failing and we inserted a logging action to determine if the workflow would execute the logging action but it did not, but wrote the same error message.
The workflow is a Reusable Approval workflow designed in SharePoint Designer 2010 and attached to a content type.
The form associated with the list was modified in InfoPath 2010.
Approvers would provide their approval in the InfoPath form which is then read by the workflow.
Side note - items created after the workflow throws this Unknown Error some seem to be working fine.
We have deleted the item in question and re-added it with no effect.
Based on what we were able to determine there don’t seem to be any consistency with how this issue is behaving.
Any suggestions on how to further investigate this issue in order to find the root cause would be greatly appreciated?
Cheers

Hi,
I understand that the reusable workflow doesn’t work properly now. Have you tried to remove the Update list item action to see whether the workflow can run without issue?
If the workflow runs perfectly when the Update list item action is removed, then you need to check whether there are errors in the update action. Check whether the values have been changed.
Thanks,

The workflow could not update the item, possibly because one or more columns for the item require a different type of information using Update Item action

I got error "The workflow could not update the item, possibly because one or more columns for the item require a different type of information "I found out the cause is Update Item action
I need to update item in another List call Customer Report ,the field call "Issues" with data type "Choice" to yes
then the error arise . please help..

Thanks for the quick response Nikhil.
Our SPF 2010 server is relatively small to many setups I am sure. The list with the issue only has 4456 items and there are a few associated lists, eg lookups, Tasks, etc see below for count.
Site Lists
Engagements = 4456 (Errors on this list, primary list for activity)
Tasks = 7711 (All workflow tasks from all site lists)
Clients = 4396 (Lookup from Engagements, Tslips, etc)
Workflow History = 584930 (I periodically run a cleanup on this and try to keep it under 400k)
Tslips = 3522 (Engagements list can create items here, but overall not much interaction between lists)
A few other lists that are used by workflows to lookup associations that are fairly static and under 50 items, eg "Parters Admin" used to lookup a partners executive admin to assign a task.

Interactive Report will not save BLOB Column Attributes

I have created many interactive reports with 4.0 and 4.1 that had BLOB columns with no problems and the download link worked fine. After upgrading to 4.2, the interactive reports get the following error when clicking on the download link:
Not found
The requested URL /apex/apex_util.get_blob was not found on this server
If I open the edit page from the report, the BLOB downloads fine. When I looked at the report attributes details for the BLOB column, I noticed the BLOB Column Attributes had not been populated. I have tried repeatedly to populate them (Table Name, Column Name, Primary Key, MIMETYPE, etc.) but after applying the changes and reopening the attributes page for the blob column, the values I entered are not saved.
For completeness, here is the select statement for the report:
select "DESC_ATT_ID",
"BR_ID",
"FILENAME",
"MIMETYPE",
dbms_lob.getlength("DESC_ATTACHMENT") "DESC_ATTACHMENT"
from "#OWNER#"."ALTEC_BR_DESC_ATT"
WHERE BR_ID = :P3_BR_ID
Also, here is the value for the Number/Date format for the BLOB Column:
DOWNLOAD:ALTEC_BR_DESC_ATT:DESC_ATTACHMENT:DESC_ATT_ID
Can someone please point me in the right direction to get the link for the interactive report working properly?
Many thanks,
Jerry

Hello,
How about you do not use BLOB format Column, you do it manually as this example here:
apex.oracle.com
workspace: somefeto
user: test
pwd: test
Application 63066
in the same workspace, there is Sample File Upload and Download (App ID 10540), and it is working fine ....
Otherwise, Pls, reproduce the problem on apex.oracle.com

In Oracle ebook:
Oracle® Database Reference

the comments about the NULLBLE column are as follows:
"Specifies whether a column allows NULLs. Value is N if there is a NOT NULL constraint on the column or if the column is part of a PRIMARY KEY. The constraint should be in an ENABLE VALIDATE state."
BUT BY DEFAULT ALL CONSTRAINTS ARE IN VALIDATE STATE

Updating a blob column using a ResultSet

Hi,
I'm using jdeveloper 3.2.3 with a 9i database and the smartupload component to save file in a blob column.
I'm using the following code
String sSql0 = "SELECT DOCUMENT.NEXTVAL FROM DUAL";
oracle.jbo.html.jsp.JSPApplicationRegistry appRegistry = oracle.jbo.html.jsp.JSPApplicationRegistry.getInstance();
appRegistry.registerApplicationFromPropertyFile(session,"dgpa_bd_BdModule");
ApplicationModule am = appRegistry.getAppModuleInstance("dgpa_bd_BdModule",request,session);
ApplicationModuleImpl appMod = (ApplicationModuleImpl)am;
PreparedStatement stmt1 = appMod.getDBTransaction().createPreparedStatement(sSql0, 1);
String sSql2 = "SELECT t.* FROM TGTDOCD0 t WHERE IDOCUMEN = 32";
Statement stmt2 = stmt1.getConnection().createStatement(ResultSet.TYPE_FORWARD_ONLY ,ResultSet.CONCUR_UPDATABLE);
ResultSet rs = stmt2.executeQuery(sSql2);
if (rs.next()) {
// Initialization
mySmartUpload.initialize(pageContext);
// Upload
mySmartUpload.upload();
// Add the current file in the DB field
mySmartUpload.getFiles().getFile(0).fileToField(rs,"gdocumen"); //gdocumen is the blob column
// Update
rs.updateRow();
rs.close();
stmt2.close();
But when i run the rs.updateRow() i have the follwing error: java.sql.SQLException: ORA-01008
what's i'm doing wrong?
Thanks

BLOB column's image is not showing up in Forms

Hi All,
I am using Forms 10g. I created a default form (using wizard) for a table that has a BLOB column. Form builder automatically created an image item that corresponds to the BLOB column. The problem is that when I run the, the image item is always blank, and is not showing any image. Although I know that the BLOB column contains valid images, which I can see using PL/SQL developer tool.
The form is compiling without error, and also, there is no runtime error message. So without reporting a compile time/runtime error, the Form is not showing the image. Can anybody help me plz??? this is urgent, any help will be greatly appreciated.
Thanks in Advance.

Hi,
I am simply using the Forms default "EnterQuery" and "ExecuteQuery" buttons. I have not written a single line of code. That is, just using the forms default funcionality.
Thanks.

Hello,
Your CTE bases only on fix value = @StartDate , not on a table/view; here do you want to insert data to? This don't work in any way.

Automatic row processing query should not update key columns

We have an APEX application to maintain a table A, which is referenced by a huge table B (several millions rows). If a row is updated (by automatic row processing), the following update statement is executed.
update "MM_DWH"."A" set "ID" = :DML_BV0001,"NAME" = ... where "ID" = :p_rowid
Due to the foreign key constraint of table B, we have situations where this update statement is blocked (Enq: TM - contention) for a long time if we have inserts into table B at the same time - I guess.
My questions are:
Why is column ID updated, this does not make sense?
Is there a way to prevent that behavious or do I have to code the update statements manually instead of using the automatic row processing feature?
Thanks and regards, Maren

What is column "ID" - the PK for A or the FK to B?
