Problems writing BLOB data into O8i (ADO and AppendChunk)

We have a table where you want to store bianry data (BLOBs). I
have used the LONG RAW datatype to store this information. Here
is the code for the table:
CREATE TABLE "CONTENTBLOBTABLE" (
DIGEST NVARCHAR2(40) NOT NULL,
BLOB LONG RAW,
CHECK (DIGEST IS NOT NULL),
PRIMARY KEY (DIGEST)
Then we try to update this table with ADO 2.6 on a Windows 200
machine with Oracle ODBC driver. Here is the relevant code
snippet:
// set the value of the field
pRs->AddNew();
pRs->Fields->GetItem("DIGEST")->PutValue(strDigest);
pRs->Fields->GetItem("BLOB")->AppendChunk(varBLOB);
if(!pRs->Update())
C_LOG_CRITICAL(L"CC_CS_DAL::WriteBLOB - pRs->Update failed");
*error = C_CS_CBT_ERROR;
pRs->CancelUpdate();
pRs->Close();
m_pConn->Close();
m_spObjectContext->SetAbort();
return S_FALSE;
OK, NO error occurs: no exception, HRESULT return values are all
OK, method completes.
BUT: there is no data in the table!?!?! When querying the exact
same table we get an empty result!
Any ideas please?
Thanks,
Christian

How to convert BLOB data into string format.

Hi,
I have problem while converting blob data into string format.
for example,
Select dbms_lob.substr(c.shape.Get_wkb(),4000,1) from geotable c
will get me the first 4000 byte of BLOB .
When i using SQL as i did above,the max length is 4000, but i can get 32K using plsql as below:
declare
my_var CLOB;
BEGIN
for x in (Select X from T)
loop
my_var:=dbms_lob.substr(x.X,32767,1)
end loop
return my_var;
I comfortably convert 32k BLOB field to string.
My problem is how to convert blob to varchar having size more than 32K.
Please help me to resolve this,
Thanx in advance for the support,
Nilesh

Nilesh,
. . . .The result of get_wkb() will not be human readable (all values are encoded into some binary format).

Import BLOB data into Database

I am trying to import data into a database, via the imp command. However, it creates the rows in the tables, without the original blob data or its somehow lost the internal link to it.
What could I be doing wrong, and what needs to be done to correct it?

I think, it was already answered, what the basis problem for such a question is:

Writing String Data into a table

Hi,
I am facing a problem in writing the data into table. Below is its description:
1. I have created a code which reads the URLs from OPC.server.
2. I need to display it in a table. Since the number of URLs are known, I have defined the rows of the Table.
3. But am not able to display those URLs in the Table.
This problem can be simply put as to "how to write string datatype to the table". can property node be used and if yes, which property can be used??
I am still a beginner in this....so would like help from all of fellow LabVIEWers out there
Thanks & Regards,

I assume you get the URLs as Strings and read it in a loop.
Let the output autoindex on the loop-out, r-click and create indicator.
That'll give you an array of strings that'll fill and show once the loop has completed.

Inserting blob data into database

Hello everybody,
I need insert blob data into database. that data i need to get from form
can i use request.getParameter(""); for getting that file.
Plz help how to get data from form to servlet and through callablestatement i need to insert into database.

Anil

Hi,
1) first create a form with file element
first.jsp
<form action="GetData" enctype="multipart/form-data" method="post">
<input type="file" name="datafile" size="40">
<input type="submit" value="Send">
<input type="reset" name="Reset" value="Cancel">
</form>
GetData.java
// servlet file
public void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException
res.setContentType("text/html");
PrintWriter out = response.getWriter();
try {
System.setProperty( "jdbc.drivers", "com.microsoft.jdbc.sqlserver.SQLServerDriver" );
Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver" );
con = DriverManager.getConnection( "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=JAVATEAM;SelectMethod=cursor;User=sa;Password=urpassword" );
PreparedStatement pst = con.prepareStatement("insert into uploads(binaryfile) values(?)");
FileInputStream fis=new FileInputStream(request.getParameter ( "datafile" ) );
byte[] b= new byte[fis.available()+1];
fis.read(b);
pst.setBytes(1,b);
pst.executeUpdate();
pst.close();
con.close();
catch(SQLException e)
out.println ( e);
catch (ClassNotFoundException e)
out.println( e );
}Here in doPost(), i create preparedstatement,
now you to create one procedure for insert
and by using callable statement you just call that procedure and pass this byte b as arguments,
now its in your hands
my idea is over.

Dynamically generating the ssrs dataset and filling the data into the dataset and binding it to ssrs report dynamically

I have a work to do, in ssrs we are using server reports in our project. i am looking for dynamically generating the ssrs dataset and filling the data into the dataset and binding the dataset to ssrs report(RDL) dynamically.
Getting the dataset dynamically has a solution by using Report Definition Customization Extension (RDCE), but the problem is binding that dataset to the report(RDL) dynamically was not there.
Here is the reference for RDCE http://www.codeproject.com/Articles/355461/Dynamically-Pointing-to-Shared-Data-Sources-on-SQL#6
I looked for binding the dataset to the report(RDL) dynamically and searched many sites but i did not get the solution. Can anyone help me here.
Is there any custom assemblies or any Custom data processing extensions to work around. Please help.
Thanks in advance

Facing problem while loading data into XI

Hi All,
I am facing a peculiar problem while loading data into XI when we load small amount of data say 5-10 records these records gets processed, but when we try to load a bit higher volume say 100-500 which comes out to be around 7 record s per second then the record processing gets stalled. That is it gives a message that "recorded for outbound processing".
So can any body throw some light on it and can tell us why we rare facing such problem and how can we resolve that problem.
Thanks in Advance.

Hi rahul,
Deregistering and Registering the Queue is a temporary solution.
The better way to this would be to Tune your Xi system as already mentioned by Vijaya as mentioned in the guide ,

Problem with BLOB data type and acute characters

Hi all, I have an issue related with BLOBS cols:
I have table A with a BLOB column and I need to insert that data into another table B, the thing is I use dbms_lob.read() that returns data into a RAW variable and then I convert it to a varchar2(with utl_raw.cast_to_varchar2) and it works ok if I have no "acute characters" on it, e.g Québec.
If I have acute characters, the "é" is inserted wrongly with an "¿" character on the table B. I tested the BLOB on the table A to check the data and the BLOB is showing correctly the "é" character, it seems that the dbms_lob.read() funct cannot handle accute characters and replace them with "¿".
How can I replace acute characters when I use the dbms_lob.read functionality?
Thank you!

Writing BLOB column into a csv or txt or sql files

Hi All,
I am having a requirement where i have to upload a file from user desktop and place that file into a unix directory. For this i am picking that file into a table using APEX and then writing that file in unix directory using UTL_FILE.
The problem which i am facing is that after this every line in my file is having ^M character at the end.
For this i modified my BLOB column into a CLOB column and then also i am facing the same problem.
Is there any way to get rid of this as i have to upload these csv or txt files into tables using sql loader programs. i can;t write any shell script to remove ^M character before uploading as this program will be merge with existing programs and then it will require lots of code change.
Kindly Help.
Thanks
Aryan

Hi Helios,
Thanks again buddy for your reply and providing me different ways.... but still the situation is i can;t write any shell script for removing the ^M. I will be writing into a file from CLOB column.
Actually the scenrio is when i am writing a simple VARCHAR columns with 'W' mode then it is working fine, but i have a BLOB column which stores the data in binary format so i am converting that column into CLOB and then writing it into file with 'W' mode but then i am getting ^M characters. As per your suggestion i have to then again run a program for removing ^M or i have to modify all my previous programs for removing ^M logic.
I want to avoid all these, and just wanted a way so that while writing into a file itself it should not have ^M. Else i have to go for a java stored procedure for running a shell script from sql, and in this still i am having some problem.
Thanks Again Helios for your time and help.
Regards
Aryan

Problem writing meta data changes in xmp in spite of enabled settings

Dear Adobe Community
After struggling with this for two full days and one night, you are my last hope before I give up and migrate to Aperture instead.
I am having problems with Lightroom 5 writing meta data changes into xmp and including development settings in JPEG, inspite of having ticked all three boxed in catalog settings.
In spite of having checked all boxes, Lightroom refused to actually perform the actions. I allowed the save action to take a lot longer than the saving indicator showed was needed, but regardless of this no edits made in the photo would be visible outside Lightroom. I also tried unticking and ticking and restarting my compute.
Therefore, I uninstalled the program and the reinstalled it again (the trial version both times). I added about 5000 images to Lightroom (i.e. referenced). After having made a couple of changes for one photo in development settings, I tried closing the program. However, then this message was then displayed:
I left the program open and running for about 5-5 hours, then tried closing the program, but the message still came up so I closed the program and restarted the computer. I tried making changes to another photo, saving and then closing and the same message comes up. The program also becomes unresponsive, and of course still no meta data has been saved to the photo, i.e. when opening it outside Lightroom, the edits of the photos is not shown.
What do do? I would greatly appreciate any insights, since I have now completely hit the wall.
Oh yes, that´s right:
What version of Lightroom? Include the minor version number (e.g., Lighroom 4 with the 4.1 update).
Lightroom 5.3
Have you installed the recent updates? (If not, you should. They fix a lot of problems.)
I installed the program two days ago and then for the second time today.
What operating system? This should include specific minor version numbers, like "Mac OSX v10.6.8"---not just "Mac".
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63 Safari/537.36
What kind(s) of image file(s)? When talking about camera raw files, include the model of camera.
JPEG
If you are getting error message(s), what is the full text of the error message(s)?
Please see screen dumps above
What were you doing when the problem occurred?
Trying to save metadata + trying to open images that it seemed I had saved meta data to
Has this ever worked before?
No
What other software are you running?
For some time Chrome, Firefox, Itunes. Then I closed all other software.
Tell us about your computer hardware. How much RAM is installed? How much free space is on your system (C:) drive?
4 GB 1333 MHz DDR3
Has this ever worked before? If so, do you recall any changes you made to Lightroom, such as adding Plug-ins, presets, etc.? Did you make any changes to your system, such as updating hardware, printers or drivers, or installing/uninstalling any programs?
No, the problems have been there all the time.

I think you succeeded in partly convincing me. : ) I think I will go for a non-destrucitve program like LR when I am back in Sweden, but will opt for a destructive one for now. Unfortuntately, I have an Olypmus- so judging from your comment NX2 might not be for me.
Hi AnnaK (see below).

My old snaps are JPEG, but I recently upgraded to an Olympus e-pl5 and will notw (edited by RC) start shooting RAW.
Note: I edited your statement: I assume you meant now instead of not.
If you start shooting raw, then you're gonna need a raw processor, regardless of what the next step in the process will be. And there are none better for this purpose than Lightroom, in my opinion. As has been said, you can export those back to Lightroom as jpeg then delete the raws, if storage is a major issue, or convert to Lossy DNG. Both of those options assume you're willing to adopt a non-destructive workflow, from there on out anyway (not an absolute requirement, but probably makes the most sense). It's generally a bad idea to edit a jpeg then resave it as a jpeg, because quality gets progressively worse every time you do that. Still, it's what I (and everybody else) did for years before Lightroom, and if you want to adopt such a workflow then yeah: you'll need a destructive editor that you like (or as I said, you can continue to use Lightroom in that fashion, by exporting new jpegs and deleting originals - really? that's how you want to go???). Reminder: NX2 works great on jpegs, and so is still very much a candidate in my mind - my biggest reservation in recommending it is uncertainty of it's future (it's kinda in limbo right now).
AnnaK wrote:
Rob Cole wrote:
There is a plugin which will automatically delete originals upon export, but relying on plugins makes for additional complication too.

Exportant (the option is invisible by default, but can be made visible by editing a text config file). To be clear: I do not recommend using Exportant for this purpose until after you've got everything else setup and functioning, and even then it would be worth reconsidering.
