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 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

Unable to set default date for Date Picker item using Auto Row Processing

Okay, I have searched through the forum for an answer, and have not found a thing to account for my problem.
First, does anyone know if using Auto Row Processing has problems updating an item/field in a record where the Source is defined as Database Column if the 'Display As' is defined as 'Date Picker (MM/DD/YYYY)'?
I ask this only because I found out the hard way that Auto Row Processing does NOT fetch the value for an item where the field is defined as TIMESTAMP in the database.
My problem is as follows: I have a form that will CREATE a new record, allowing the user to select dates from Date Pickers, text from Select Lists, and entering in text into a Textarea item. The information is saved using a standard (created through the Auto Row Processing wizared) CREATE page level button. After the record is created the user is able to go into it and update the information. At that time, or later, they will click on one of two buttons, 'ACCEPT' or 'DECLINE'. These are Item level buttons, which set the REQUEST value to 'APPLY' (Accept) and 'UPDATE' (Decline). The Accept button executes a Process that changes the Status Code from 'Initiated' to 'Accepted', and sets the Declined_Accepted_Date to SYSDATE, then another Process SAVEs the record. The Declined button runs a Process that changes the Status Code from 'Initiated' to 'Declined', and sets the Declined_Accepted_Date to SYSDATE, then another Process SAVEs the record.
However, even though the Status Code field is updated in the database record in both Accepted and Declined processing, the Declined_Accepted_Date field remains NULL in the database record (by looking at the records via SQL Developer). WHY??? I looked at the Session State values for both the Status Code and the Declined_Accepted_Date fields and saw that the fields (items) had the expected values after the process that SAVEs the record.
The following is the code from the Accept button Page Process Source/Process:
BEGIN
:P205_STATUS_CD := 'A';
:P205_REF_DECLINE_ACCEPT_DT := SYSDATE;
END;
As can be seen, the Status Code and Declined_Accepted_Date items are set one right after the other.
As an aside, just what is the difference between Temporary Session State vs Permanent Session State? And what is the sequence of events to differentiate the two?

Here's yet another thing that I just looked into, further information...
One other difference between the date field I am having problems with (Accepted_Declined_Date), and other dates (with Date Pickers) in the record is that the Accepted_Declined_Date never gets displayed until after it is set with a default date when the Accept and Decline buttons are pressed.
One of the other dates that works, the Received Date, is able to write a default date to the record that is never typed into the box or selected from the calendar. That date is placed into the box via a Post Calculation Computation in the Source, which I set up as: NVL(:P205_REF_RECEIVED_DT,TO_CHAR(SYSDATE,'MM/DD/YYYY'))
However, I do remember actually trying this also with the Accepted_Declined_Date, and setting the Post Calculation Computation did not work for the Accept_Decline_Date. Could this be because the Accept_Decline_Date is never rendered until the Status Code is set to Declined (in other words, there is no need to display the date and allow the user to change it until the record is actually declined)???
The control of the displaying (rendering) of the date is set via the Conditions / Condition Type: Value of Item in Expression 1 = Expression 2
Expression 1 = P205_STATUS_CD and Expression 2 = L
Does this shed any light???

Iphoto 9.5 won't import photos from iPhoto 7.5. Library will not update using the iPhoto library upgraded application.

iphoto 9.5 won't import photos from iPhoto 7.5. Library will not update using the iPhoto library upgrader application. Repeatedly says it can't locate photos even when told to cancel. I think the photos in question are in Nikon RAW format.

iPhoto 9.5 immediately tries to "upgrade" my library using the upgrader.
iPhoto 9.5 asks you to run the upgrader to prepare the library for 9.5. It then will update the library to its format.
You need to do the following:
1 - go to your Applications/Utilities folder and double click on the iPhoto Library Upgrader 1.1 application.
2 - select Choose Library, navigate to your iPhoto library, select it and let the upgrader do its thing.
3 - launch iPhoto 9.5 to open and finish the conversion of the library.

Automated Row Process not inserting correctly??

This is the first time I've gone through this, and if it worked I would be simply amazed. I have a button set to submit as INSERT. I have the checkbox checked inside my automated process allowing it to insert.
I did move some thigns around, just order numbers, but didn't rename anything. When I push the insert button it tells me that the action was processed, and branches to the next page, but it doesn't show up in the Database.
Any ideas of where to start here?

Neilio - It sounds like you have a form page. Does this page have an Automated Row Fetch process? Do the form items use Source Type 'Database Column'?

Inserts using Automatic Row Processing (DML) should not clear cache

Hi,
I am using APEX 4.0.1.00.03.
I created a form on a table for inserts and updates.
After I do an insert, the Automatic Row Processing (DML) clears cache for all items on the page.
But the user wants to see the data he inserted without having to query. How can I achieve this?
Thanks
Chandra

There isn't any "reset page" process on my page.

Solved: Delete Using Automatic Row Processing

See Scott's reply below for the answer.
Hi there,
I have an application built in APEX 3.0.1 that I would like to be able to use a button to delete a single row from an underlying database table (owned by the parsing schema).
My APEX page has a 3 HTML regions on it:
1. Only a Select List and Go button for User selection (of Debit Note)
2. Ten display Items (Text Field, Disabled saves state) displaying further information about User selection
3. Conditional Delete button (region with custom image) - only displays when P73_DEBITNOTEID is NOT NULL
I'd like this button to be used to Delete the Selected Item and thought I'd be able to use a Data Manipulation Page Process - Automatic Row Processing (DML) page process to do this.
However, when I go through the wizard the Select item containing primary key column value field has no values in the search list.
My first question is why was there no values in the list?
So I manually entered the Item I required (P73_DEBITNOTEID) but when I run the page and click the button I get a PL/SQL missing expression error.
What is the best practice method to do DML actions on the underlying database tables. The tables are all owned by the parsing schema.
Your help in resolving this matter would be greatly appreciated.
Kind Regards,
Gary.

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.

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.

Results not updating for every row in BIpublisher

Hi all I have a Bi publisher report that is updating the results for the first row and in the second row to update the results it is picking the values from the first column itself and using the same values for all the other rows.
Here is my report format
Month saves Total, for 30,60,90,120
Jan
feb
Mar
Total are the enrolls by each month and days shows after 30,60,90,120 how many are still active. Following eg should give an idea of exactly whats happening
Eg:
Total 30days 60days 90days 120days 150days 180days 210days
------------------------------------------------------------------------------------------------------------------------------------------------------------ Jan saves 330 287 274 270 263 262 259 257
Feb saves 298 255 242 238 231 230 227 225
Mar saves 291 248 235 231 224 223 220 218
So what is happening is lets say for example there are a total of 330 enrolls in january and after 30days 287 are still active and after 60days 274 are still active after 90 270...... etc
Am getting the January active values correctly.
BUt going forward when I see the values for february The total enrolls for february is 298 and after 30 days which are active is not giving me the correct.
It is substracting the same amount as jan. looking at the numbers it is substracting
-43, -13,-4,-7,-1,-3,-2 for Jan which are the cancels after the consecutive days
It is substracting the same amount for feb also but my actual cancels for feb are different it should be 45,12,8,9,2,2,
It is doing the same for all the months.
There should be a change in the code. Following is the XSL code am using in
<?xdoxslt:set_variable($_XDOCTX, 'v_SavesCanceled', SAVES_CANCELED_COUNT)?>
<?xdoxslt:set_variable($_XDOCTX, 'v_RtSaves', xdoxslt:get_variable($_XDOCTX, 'v_RtSaves') - xdoxslt:get_variable($_XDOCTX, 'v_SavesCanceled'))?>
<?xdoxslt:get_variable($_XDOCTX, 'v_RtSaves')?>
Actually the cancels should be updated for each row but its picking the same cancels for every month.
Hope it is clear let me know if you need any further info
Any help is appreciated.
Thanks

Thank you very much for your help. The rtf file sent worked and updating results as required.Thank you
Thanks

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.

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

Problem with blob column index created using Oracle Text.

Hi,
I'm running Oracle Database 10g 10.2.0.1.0 standard edition one, on windows server 2003 R2 x64.
I have a table with a blob column which contains pdf document.
Then, I create an index using the following script so that I can do fulltext search using Oracle Text.
CREATE INDEX DMCS.T_DMCS_FILE_DF_FILE_IDX ON DMCS.T_DMCS_FILE
(DF_FILE)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('DATASTORE CTXSYS.DEFAULT_DATASTORE');
However, the index is not searchable and I check the following tables created by database for my index and found them to be empty as well !!
DR$T_DMCS_FILE_DF_FILE_IDX$I
DR$T_DMCS_FILE_DF_FILE_IDX$K
DR$T_DMCS_FILE_DF_FILE_IDX$N
DR$T_DMCS_FILE_DF_FILE_IDX$R
I wonder what's wrong with it.
My user has been granted the ctx_app role and I have other tables that store plain text which I use Oracle Text are fine. I even output the blob column and save as pdf file and they are fine.
However the database seems like not indexing my blob column although the index can be created without error.
Please advise.
Really appreciate anyone who can help.
Thank you.

The situation is I have already loaded a few pdf document into the table's blob column.
After I create the Oracle text index on this blob column, I find the system generated index tables listed in my earlier posting are empty, except for the 4th table.
Normally we'll see words inside the table where those are the words indexed by oracle text on my document.
As a result, no matter how i search for the index using select statement with contains operator, it will not give me any result.
I feel weird why the blob is not indexed. The content of the blob are actually valid because I tested this by export the content back to pdf and I can still view and search within the pdf.

Jap.

Problem full-text in blob column index created using Oracle Text

Hi,
I'm running Oracle Database 10g 10.2 on solaris
I configure Oracle text if i look for in a varchar2 column is ok, but with blob column doesn't works the search.
I have a table with a blob column which contains document. I load document with Oracle UCM (stellent)
My index scripts is:
CREATE INDEX ORAUCM.FT_IDCCOLL1 ON ORAUCM.IDCCOLL1
(DDOCFULLTEXT)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('DATASTORE CTXSYS.DEFAULT_DATASTORE FILTER CTXSYS.AUTO_FILTER FORMAT COLUMN DFULLTEXTFORMAT CHARSET
COLUMN DFULLTEXTCHARSET LEXER OCS_IDCCOLL1_LEXER SYNC (ON COMMIT)')
NOPARALLEL;
And my select retunm 0 rows although it will be many documents:
SELECT IdcColl2.dID, dDocName, dDocTitle, dDocType, dRevisionID, dSecurityGroup, dDocAuthor,
dDocAccount, dRevLabel, dFormat, dOriginalName, dExtension, dWebExtension, dInDate, dOutDate,
dPublishType, dRendition1, dRendition2, VaultFileSize, WebFileSize, URL, dFullTextFormat,
dFullTextCharset, DocMeta.*
FROM IdcColl1, DocMeta
WHERE IdcColl1.dID=DocMeta.dID AND (CONTAINS(dDocFullText,'SUBIR') > 0 )
ORDER BY dInDate Desc
Thanks in advance.

Thank you for your answer.
I response your question:
- yes DDOCFULLTEXT is a BLOB column.
- The document that word, excels, whatever. We load the document with UCM (universal Content Management)
because i need full-test search form UCM tool.
- Yes 'subir' containts in the word document.
- select * from CTX_USER_INDEX_ERRORS ;
No rows returned.
- SELECT TOKEN_TEXT FROM DR$FT_IDCCOLL1$I
No rows returned.
- I tried create symplifying index and doen't work.
I tried create table and index context on oracle 10.2.0.3 (test database)and works ok.
I compared both context (test database and ucm database) and i saw a difference:
In ucm database there are these preferences "analyze text"
BEGIN ctx_ddl.create_preference('ORAUCM.', 'WORLD_LEXER'); end;
BEGIN ctx_ddl.create_preference('ORAUCM.', 'DETAIL_DATASTORE'); end;
I don't know if is important diference or no.
Please if you need more information, tell me.
Thanks for your time.
