What is the size of the blob column?

can we measure the size of the blob column in bytes? if so how to do it?

What is the best column width & font size for an ipad magazine

I'm creating a magazine that will be shown on the ipad I was wondering what is the best column width and font size to use. If someone has any suggestions I'd love the help.
thanks,

You should know how you publish it and what the technical limitations of each type are.
No one can or will give you any advise to use this or that font. Make several drafts, try it, pass on several drafts to testers and get response.
If you work with styles, it is then easy for you to change it to the best result with a few clicks.
Normally a column width with 37 to 45 letters I would personally suggest to be the best width, but opinions are very different on it. The more letters in a line the less readability is given, the less letters the more difficulty you will have to get an even grey factor. (I mean that through space between words some lines become bright others dark, which does not look so fine, I don't know the English technical term for that.)

Hi
I am doing DataBase Lookup in XI
First i have created a Table in Database( CheckUser) which has two fields UserName and PhoneNumber and then i have created
I have created one Communication Channel For Reciever Adapter .
I have given the parameters like this
JDBC Driver : com.microsoft.jdbc.sqlserver.SQLServerDriver
Connection : jdbc:microsoft:sqlserver://10.7.1.43:1433;DatabaseName=Ravi;
UserName.... sa
password.... sa
persistence : Database
Database Table Name : CheckUser
Key column name and Value column name i left blank and activated
and then
I have created
Data Types : Source ...... UserName
 Destination.... PhoneNumber
Message Types
Message Interfaces
In Message Mapping
 I have created one User Defined function DBProcessing_SpecialAPI().This method will get the data from the database....
In this function i have written the following code
 //write your code here
String query = " ";
Channel channel = null;
DataBaseAccessor accessor = null;
DataBaseResult resultSet = null;
query = "select Password from CheckUser where UserName = ' " +UserName[0]+ " ' ";
try {
 channel = LookupService.getChannel("Ravi","CC_JDBC");
 accessor = LookupService.getDataBaseAccessor(channel);
 resultSet = accessor.execute(query);
 for(Iterator rows = resultSet.getRows();rows.hasNext();){
 Map rowMap = (Map)rows.next();
 result.addValue((String)rowMap.get("Password"));
catch(Exception e){
 result.addValue(e.getMessage());
finally{
 try{
 if(accessor != null)
 accessor.close();
 }catch(Exception e){
 result.addValue(e.getMessage());
And the i have mapped like this
UserName -
> DBProcessing_SpecialAPI----
>PhoneNumber
when i am testing this mapping i am getting the following error

Is there anyway to tell what is the database column behind the form field (

Is there anyway to tell what is the database column behind the form field (in Oracle financials).

If you are lucky, it can be simple, but if you are unlucky, it can be very complicated.
Using Help > Diagnostics > Examine when in the field will give you the name of the field.
Help > Diagnostics > Examine (Block: SYSTEM / Field: LAST_QUERY) will give you the query for the last block queried, which may or may not be the block you want, depending on how the form is defined (ie Master Detail relationships). If this is for the correct block and the field name is one of the columns returned by the query, then that is probably your answer.
If the Last Query is not for the correct block, using Help > Record History will give you the table or view that the block is based on (only where there is already a record in the block).
If the field name matches a column name in the table or view, then that is probably where it comes from. If there is no matching column name in the table or view, then the field is probably not queried directly from the database as part of the main query - it is probably populated by logic in the form, like the POST-QUERY trigger on the block. This means you need to open the form in Forms Builder to find what is populating your field (Program > Find and Replace PL/SQL is very handy for this).

when i am excuting the above code it is not bringing the exact binary values from the database ?
can any one help me on this?
Thanks
Rangan S

On another note it's always a good idea to tell us what database version you are using e.g. 9.2.0.7 or 10.2.0.3 etc. as this will allow us to tailor our answers appropriately in case there are features we can't use because you are using an older version.
And, when posting code, please put {noformat}{noformat} tags around it so that it keeps its formatting on the forum.

What are the blob files on the agents?

Question:
In /opt/local/aduva/director_agent/blobs/
There are multiple files with the suffix .blob
What are they?
Answer
The blob files are the actual software packages downloaded by the UCE server from the Universal Software Component Repository. This occurs once you have approved the installation of a component and are not downloaded again if they are present in the appropriate directory.
This may be Solaris patches or RPM files depending on the managed channel of that host.

To see what the file is type on the command line
file xxxxx.blob where xxxx is the name of the blob. the file command will return the name of the rpm or that the file is a script.

What sets the 'Kind' column in Finder windows?

Since installing Snow leopard, I have been finding that just inserting a flash card containing Olympus raw image files into a USB card reader and displaying the contents, shows a strange phrase in the Kind column: "Lightzone transform format".
Lightzone is one of several photo processing applications in my Applications folder, but the same column used to show the more general "Olympus raw file" in the Kind column.
This is causing me trouble when I set iPhoto to use an external editor.

I tried this, and first I was encouraged, and then I was disappointed.
I shut down all running programs and then did the terminal operation you recommended. Then I restarted.
I then put a flash card in a reader abnd opened it in the Finder. I was relieved to see that the Kind column read "Olympus raw file" as it should. I then set up iPhoto to use Olympus Stdio 2 as the external editor. I imported this set of image files (all of them on the card) into iPhoto, and then double-clicked one.
I saw a message window with the following: The document P1234.ORF could not be opened. Olympus Studio 2 cannot open files in the "Preview.app Document" format.
This turn of events was the whole reason that I needed to correct this symptom (the wrong label in the Kind column, I thought). Note that I had in the past used the Information panel on a .ORF file to change 'Open with' to preview.app. but I had hoped that this Terminal operation would have kept this from propagating to these new files, that had never been opened in Preview, but only imported ointo iPhoto.

Oracle Lite 10.3.0: how to find out the consumed size of a BLOB column

Hi,
we are developing an app that utilizes an Oracle Lite database and so far I have just been unable to find a reasonable way to determine the size of stored binary data.
All the "usual" ways we aware of from "main" Oracle just don't seem to work with OLIte (ie SELECT dbms_lob.getlength(file_data) from APPS.CSL_LOBS) so how does one find out the size of blob objects?
Thanks in advance

What is the Location column in Thunderbird?

What I *want* it to be is the folder the e-mail is currently stored in, when I am looking at my search folders, like _All Mail_ or _With Attachments_. As it is, it seems to *always* be empty. What is it?

Well, I would *like* it to do something useful, but currently it just shows as empty. It isn't enabled by default - I enabled it to see if it will serve my needs. If someone could tell me what its purpose is, and under what circumstances it contains any data at all, then I would know if I could make it serve my purpose.
What I *need* is a column that tells me where the e-mail is located (or, in the case of GMail, what tags are associated with the e-mail, which Thunderbird treats as "Folders")

What is the ReplacesDialogIDTime column used for in the CDR database?

I have been writing some reports using SQL aganist the Lync CDR database - looking mainly at the SessionDetails and VoipDetails tables.
I have come across some instances where the duration of the call (session start - session end) is not acurrate, but I can see other records in the sessiondetails table with the replacesdialogidTime is the same as the SessionIDTime in the original record.
Does anyone know why Lync does this and why ?

There is no HashCode class in Coherence (at least I cannot find one in the 3.5.2 jar).
I can only assume you actually mean the hashCode method, which is part of standard Java and is declared on the Object class that every class inherits from. It is actually quite important to understand how to implement it properly if you are going to override this method in your classes (which you probably should in domain objects). Try reading this which I pulled at random from Google: http://www.ibm.com/developerworks/java/library/j-jtp05273.html

Ok, that won't work...you need to generate an image tag and provide the contents of the blob column as the src for the image tag.
If you look at my blog entry -
http://jes.blogs.shellprompt.net/2007/05/18/apex-delivering-pages-in-3-seconds-or-less/
and download that Whitepaper that I talk about you will find an example of how to do what you want to do. Note the majority of that whitepaper is discussing other (quite advanced) topics, but there is a small part of it that shows how to display an image stored as a blob in a table.

How to get the File-Type from a BLOB-Column

Hi all,
I have the database table with the BLOB-Column. In this column are Word/Pdf/Excel/... files can be stored.
Now I want to open these Files from Webforms.
I can download the file from database to the client and then open the file with client_ole2.CREATE_OBJ('Word.Application');
But I can not be sure that the file is a Word-Document.
How can I know which application is saved in the BLOB-column?
Regards

Hi Francois,
thank you.
Unfortunatelly I do not know the interMedia functions. Can you send me an example with interMedia?
I am working with your solution with WEBUTIL_HOST.blocking.
But when I do not give the extension for the file, in that the BLOB will be temporary stored, I get to see the Windows "Select Program..." window. When I select Word or anything else then the file will be opened, but the locking does not working.
Any ideas?
Regards

What is the size of the blob column?
