Error updating a blob column
Hello Hello everyone,
first I created the directory images like "C:\images".
then I created the table PRICUSTOMERPROOF
Name of Type Null
------------------------ ---- ------------
CUSTOMERID VARCHAR2 (50)
IMAGEID NUMBER
NUMBER OF IDTYP
IDVALUE VARCHAR2 (50)
IDEXPDATE TIMESTAMP (6)
IDIMAGE BLOB
ACTIVEC NUMBER (1)
USERR VARCHAR2 (10)
DATED TIMESTAMP (6)
DEFAULTC NUMBER (1)
NUMBER OF CUSTOMERIDENTIFICATIONID
then I inserted all the values in the table except column IDIMAGE
then I tried to update the column with
DECLARE
l_bfile BFILE.
l_blob BLOB;
BEGIN
SELECT IDIMAGE
IN l_blob
OF PRICUSTOMERPROOF
WHERE CUSTOMERID = "Pri29098."
UPDATE;
l_bfile: = BFILENAME (upper ('images'), "Tulips.jpg");
DBMS_LOB. FileOpen (l_bfile, Dbms_Lob.File_Readonly);
DBMS_LOB. LoadFromFile (l_blob, l_bfile, DBMS_LOB.getlength (l_bfile));
DBMS_LOB. FileClose (l_bfile);
END;
When I run the codes I get
Error report:
ORA-22285: non-existent directory or file for FILEOPEN operation
ORA-06512: at "SYS." DBMS_LOB", line 805
ORA-06512: at the level of line 12

* Cause: Attempted access to a directory that does not exist, or attempted
to access a file in a directory that does not exist.
* Action: To ensure that an appropriate system specified
the directory exists in the data dictionary, or
Make sure that the name is correct.
im sure that the directory of the image exists. can someone help me get errors deleted
thanking you

Good; After the granting of privileges, it is a different matter! To do this, you will need to initialize the variable of type blob with a value of type blob (use empty_blob()). Try it
DECLARE
l_bfile BFILE.
l_blob BLOB;
BEGIN
/ * commented
SELECT IDIMAGE FROM l_blob
OF PRICUSTOMERPROOF
WHERE CUSTOMERID = "Pri29098."
UPDATE; */
Update pricustomerproof set idimage = empty_blob()
where customerid = "Pri29098."
return idimage in l_blob;
l_bfile: = BFILENAME (upper ('images'), "Tulips.jpg");
DBMS_LOB. FileOpen (l_bfile, dbms_lob.file_readonly);
DBMS_LOB. LoadFromFile (l_blob, l_bfile, dbms_lob.getlength (l_bfile));
DBMS_LOB. FileClose (l_bfile);
commit;
END;

Hello
I have Oracle XE 11.2.0 loaded on a Windows Server. It works very well. I use Apex 4.1 on break as well.
In a table, I have a column (LIST_FILE) that contains the name of a file and does not include the file extension. Recently, I added a BLOB (LIST_PDF) column to this table.
I would like to create SQL to update each row of this table by inserting PDF file into the blob. For each row in the table, there is a file beginning with value in LIST_FILE and followed by a period and PDF (.) (PDF). File1.PDF, File2, PDF, etc. The windows directory that contains the PDF files can be moved anywhere on the windows server.
How to build the SQL to update the BLOB column?
Thanks for your help.
Hi, PhilMan2
You cannot load the PDF by single SQL. It must be the script on PL/SQL. Visit this link to find out how you can make your task How to insert blob in the database file

Interactive report will not save the BLOB column attributes
I created several interactive reports with the 4.0 and 4.1 which had columns of type BLOB with no problems and the download link worked fine. After 4.2 update, interactive reports get the following error when you click 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 of the report, the BLOB downloads very well. When I looked at the report in detail the attributes of the BLOB column, I noticed that the BLOB column attributes had not been met. I tried several times to fill in (name of the Table column name, Primary Key, MIMETYPE, etc), but after applying changes and reopen the attributes page for the blob column, the values, that I entered is not saved.
For completeness, here is the select statement for the report:
Select "DESC_ATT_ID."
"BR_ID,"
"FILENAME."
"MIME TYPE"
DBMS_LOB. GetLength ("DESC_ATTACHMENT") 'DESC_ATTACHMENT '.
of ' #OWNER # '. " ALTEC_BR_DESC_ATT ".
WHERE BR_ID =: P3_BR_ID
Also, here is the value for the number/Date of the BLOB column format:
DOWNLOAD: ALTEC_BR_DESC_ATT:DESC_ATTACHMENT:DESC_ATT_ID
Can someone tell me please in the right direction to get the link to the interactive report work correctly?
Thank you very much
JerryHello
How about you, you do not format BLOB column, do you it manually like this example here:Apex. Oracle.com
workspace: somefeto
user: test
PWD: test
Application 63066in the same workspace, there is Sample File Upload and Download (App ID 10540), and it works very well...
If not, Pls, reproduce the problem on apex.oracle.com

Classic report SQL with BLOB column not refreshing with jQuery Trigger Apexrefresh call
Hello
Really hoping that someone can help me, but for some reason that I try to report updated in dynamic Action to help:
jQuery('#my-report').trigger('apexrefresh');
on a simple SQL query report classic. I have used this many times on other parts of the report but the only difference with the report region where it is not refreshing, is that the table contains a BLOB column as it is essentially a report of downloaded files that users have made to the page by using the file browse.
Would really appreciate help with that basically, I don't want to perform a full page refresh, because it currently operates.
It has to do with the fact that this report is the question about a BLOB column, which is a link to the uploaded file?
Thank you.
Tony.
Hello
Check this area of report model have id.
You should have id = "" #REGION_STATIC_ID # "in the model of the region"Make sure you have correctly write the id of the report in JavaScript. JavaScript is case-sensitive

Creating INDEX on a BLOB column in a separate tablespace
Hello
Our database contains 2 storage spaces :
-Tablespace DATA : is reserved to hold the data.
-Tablespace INDX: is reserved to hold the index.
For some reason, that we must create the indexes on columns of type blob and the pending order are:
SQL > CREATE INDEX my_index ON DOC_CONTENTS (doc_content) INDEXTYPE IS CTXSYS. CONTEXT; / / doc_content a blob type.
SQL> index created
Now, all indexes are created in the tablespace for DATA that is not good, they should be created in the tablespace INDX (now is empty)
For this reason, and after a search, I specified the tablespace INDX , which will contain the index, and the used command is:
SQL > CREATE INDEX my_index ON DOC_CONTENTS (doc_content) INDEXTYPE IS CTXSYS. CONTEXT TABLESPACE INDX;
*
ERROR on line 1:
ORA-29850: invalid option for creating domain index
NB: also, when I try to use the same command with varchar column, it works.
SQL > CREATE INDEX my_index ON DOC_CONTENTS (doc_name) TABLESPACE INDX; / / doc_content a type VARCHAR2.
SQL> index created
Do you have an idea on how to create indexes on a blob column in a different tablespace?
This question has nothing to do with the Oracle objects, but is related to Oracle Text, then perhaps that some moderator moves text objects.
To specify a storage space for a ctxsys.context Oracle Text index domain index tables, you must create a storage preference, specify storage spaces in attributes of this preference, then use this preference in settings of creating index. Please see the example below which shows first create domain index tables in the default users tablespace, then the creation of the field tables to be indexed in the example tablespace.

Stored in the BLOB column display PDF problem
Hello everyone.
I tried to follow this tutorial http://asktom.oracle.com/pls/asktom/f?p=100:11:0:p11_question_id:232814159006 on the display of PDF files stored in BLOB columns. This is done on Apex 4.2, with my DB 11 g running. I have my procedure, which I will post below:
I am trying to run this through a region dynamic PL/SQL, and even if I don't get any error, the content displayed is a huge mess of truncated text and strange characters. I tried to run this procedure on many other types of documents, including word and jpeg image files, all with the necessary changes in my inside, and regardless of what I use, I always get a big mess of strange characters. Does anyone have information or ideas why this is happening?create or replace procedure "PDF" (p_id IN gvo_documents.doc_id%type) is l_lob blob; l_amt number default 30; l_off number default 1; l_raw raw(4096); begin select contents into l_lob from gvo_documents where doc_id = p_id; -- make sure to change this for your type! owa_util.mime_header( 'application/pdf' ); begin loop dbms_lob.read( l_lob, l_amt, l_off, l_raw ); htp.prn( utl_raw.cast_to_varchar2( l_raw ) ); l_off := l_off+l_amt; l_amt := 4096; end loop; exception when no_data_found then NULL; end; end;
If I understand correctly, your needs must be broken down into two problems:
1) click the link that opens a window showing a new APEX page
(2) an APEX page displays the document, download it not.I did not (yet) #1.
However, you can generate a URL that points to the new page in the select for the report.It's a related issue, but no response yet:
Open the pdf file in the browser windowThe key is to target = "_blank" to the anchor tag.
To generate the URL, you must use the APEX_UTIL.prepare_URL () function.If this does not work, a dynamic Action that makes magical things of JavaScript may be necessary.
# 2, I lost the URL that showed how to display a PDF file in a page "form.
From what I remember:
Start with a blank page with a pristine area of HTML (all items will in the HTML area)
Add an element to the PK/annual
part I forgot Create a Data Manipulation process
-Automated row Fetch
-By loading - after the header
-(stuff for your table/view)
part I forgot Create a (I think) "File browser" item type. For the parameters:
-Storage of Type "BLOB column specified in the Source element" (and put the name of the BLOB column)
-MIME Type column: (column name) - since there are several types, this is a MUST HAVE
-Filename column: (column name) - I highly recommend you have this.
-Provision of content is INLINE<-- this="" is="" the="">-->In addition, you will need a browser for each of the Types MIME Plugin (if not, the browser may try to "Download" the file)
Browsers can manage the types of images internally. Plugin Adobe can handle PDF files. I do not know Word/Excel.Yet once again, I don't remember the exact details, but that should cover most of it.

Load the BLOB column in Oracle to an Image column in MS SQL Server
Hello
I have an Oracle table as the source and a MS SQL Server table as a target. A blob column (4000) in the source is mapped to a column (2147483647) Image in the target.
Execution will give me the error message "* java.lang.NumberFormatException: for the input string:"4294967295"*"when it comes to step 'load the data into the staging of table' '.
The LKM that I use is LKM SQL for MSSQL.
I also tried LKM SQL for MSSQL (BULK), LKM SQL for SQL (jython), LKM SQL for SQL. None of them are useful.
Impossible, someone tell me how to fix this 4294967295? Thank you very muchHi Yang,
Oracle recommends the setting of the 'get_lob_precision' false flag to avoid this error.
For this,.
1. make a backup of your ODIPARAM. BAT file.
2. open ODIPARAM. BAT file and add the following line.Set ODI_ADDITIONAL_JAVA_OPTIONS = % ODI_ADDITIONAL_JAVA_OPTIONS % ""-Doracledatabasemetadata.get_lob_precision = false ' "
Next to
Set ODI_ADDITIONAL_JAVA_OPTIONS = ""-Djava.security.policy = server.policy ' "
PS:If, the parameter is defined, the result "ODI_ADDITIONAL_JAVA_OPTIONS" ("SNP_ADDITIONAL_JAVA_OPTIONS" or "SNP_JAVA_OPTIONS") should be similar to the foregoing.
Restart the ODI and try.
Thank you

compress the blob column to save space on the server
Hi friends,
I have a problem with the blob column, in the oracle 11.2.0.4 on aix Server database
I have a table with a blob of column (containing a jpg file). This table is in a tablespace of 300 GB and storage space is full. There is no space on the server (asm).
I need to load the jpg more in this table, but there is no space.
I've read a few articles on tha compress blob type column, but I'm not sure what I should do.
Is it possible to compress the blob column without going to a different tablespace (because the server has no more space to create a new one).
The table and column have been created in a traditional way.
Please, advice?
Best regards
Dbape.
But this method requires add-on EA "Adv. Compression" ($$$).
OP he wanted to compress .jpg files.
BUDOKAI
It is not possible.
the .jpg files are already compressed.
IIRC (of my Compression Adv. test) - SecureFile "knows best" and will not try to compress BLOBs identified as JPGs or any other known formats of files (such as .zip files)
In other words - SecureFile is not the OP no good for the type of data, it is try to compress them.
Are the only solutions that the OP has to enable it to store more JPG images
- get rid of the old pictures
- Add more disks
- resize images (ordimage)
- recompress the image by reducing the quality as long as the resulting image is unusable (ordimage)
