How to store and retrieve clob data fields

Hai al l,
How to sotre resumes of a Jobseekers in Oracle Data Base.Which version is enough(8i or 9i) and CLOB or BLOB is Preferable.

Now I want to insert More than 1000000 resume Attachments (all are .doc or .rtf files).Can you suggest me on this with a sample program .I am really thankful to all of our Members support and Valuable doubt clarifications.
I am waiting for your valueble reply
thanks in advance

I am really thankful for your support and Valuable doubt clarifications.

CLOBs and BLOBs are physically stored just like any other Oracle data type, in the data files that make up the database, the .dbf files. They're not stored as seperate files that you can use outside of Oracle.
Oracle has a seperate special data type for binary objects stored outside the database, the BFILE data type. However, this type is read-only from a database connection (and therefore from JDBC); the files have to be placed on the Oracle server some other way and the BFILE object is created as a pointer to that external resource. I think built-in stored procedures are used to actually read the data from the binary object.
I've never used this datatype and can't tell you much more about it. See the documentation:

LRv3.2 Networking with an Asst , How to store and retrieve updated work on Win7?

LRv3.2 Networking with an Asst , How to store and retrieve updated work on Win7 Network?
We have a working 1gig network in Win7 PRO 64-bit. and using LRv3.2
* How do I configure our Files or Cataloges "so" ALL Edits are veiwable/edit to all?   (we don't work on the Same Shoot/Folder at the same time)
I NEED to see, ALL the LR Edits (is great with DNG files
*** BUT, what I cannot see if I remember correctly (with just the DNG sharing) is the CROP or Virtual Copys ... possibly the Brush edits.
HOW, do I configure to be able to read and edit ... ALL of the updated/saved Edits???   (after it is done by my asst.)
Is creating a New Catalog for EACH shoot the way to go?   (not sure I like this idea)
Right now everything is in one(1) catalog ... and it's getting big ... BUT, this allows us to search , and group ... going way back.
Would be nice to be able to still do this easily, and with what we have already done.
With our one BIG Catalog ... not sure if two(2) can access this catalog over the Network at the same time?
Even though we never Edit the Same Folder or Files at the same time.
Or will that be a problem over a simple Win7 PRO network?
Thank you,
HG

Deleting ALL the Folders in LR ... except for the one's that will be worked by the Asst.
Then moving that file to the Asst. Computer.
* NEXT, pointing the Folder that they are working on ... across the Network to the Servers Files.
* After they work on it:
*** IS THERE A WAY ...
* To take that Cataloge ... and UPDATE my Main Cataloge.
THIS, is the STEP ... I don't know how to do.
Can someone Help me with this?
Step by Step, because I am clueless ....
Talking UPDATE of everything worked on ... including   Virtual copys, and CROPS.
Thank you,

How the store and retrieval in ServletContext will happen??

Hello Sir,
I am developing a chat application thats in Swing & servlets Now I am able to authenticate user and I am using ArrayList to maintain the names of the user globally my storing it in ServletContext
How to store and retrieve ArrayList from Servletcontext
And another thing is that we are having personal chat(1-to-1) also. But how to use the thread model is not known to us as we have not faced such a situation before
So if you could suggest some example code or snippets ot certain links then it would be of great help to us
Thanks
Regards
Monarch

Hello
thanks for your reply. Actually we are doing the same thing that u have mentioned in your reply.
The thing we are trying to do is that when a user is logged in the particular servlet which is responsible for the authentiacation of the user will authenticate the user an then calls method in the Chatter class which is outside the servlet
The Chatter class declares two mwthods addChatter() and getChatter()
I am managing the currently logged users in Arraylist using this two mehtods above
When the first user logs in his entry gets stored at the first position in the arraylist but when other user logs in then his entry overrites the entry of the first user instead of getting stored in the next position.
The arraylist gets initialized when second user logs in. to overcome this problem i want to store the arraylist into the ServletContext so it will be unique for the whole application and will not get initialized
So I want to know the process of storing and retrieving the arraylist fro the context
Hope ull understand me and reply me
Thanks
Regards

FETCH DATA FROM ORACLE DATABASE USING Web Dynpro

I want to fetch data from ORACLE database using Web Dynpro.How can I do this?

1) Are you sure that you get no results? It sounds like you are having name resolution issues, which would imply that you should be getting an ORA-00942 error indicating that the table doesn't exist (or that you don't have access to the table). If you are not seeing this error, I would tend to suspect an overzealous exception handler.
2) What database account owns the table? What database account is your ASP.Net application using to connect? Assuming these two accounts are different, your application would either have to
- Explicitly prefix the table name with the schema name
- Have a public or private synonym that maps the table name to the fully qualified identifier schema_name.table_name
- Issue the command ALTER SESSION SET CURRENT_SCHEMA = <<schema name>> in each session, in which case all queries in the session would use the specified schema name as the default if no schema name is prefixed.

How to store and retrieve XML messages in AQ using ESB/ BPE

Hello,
I am having a requirement which I feel should be fairly common - store and retrieve XML messages in AQ. However, I am struggling to decide which type of queue to use AQ or JMS...Here is the requirement
1. In an ESB, I want to read different kind of files using file adapter. Different kind as in, having different structure or schema
2. I want to create a queue that is capable of storing any kind of xml data. To this queue, I want to enqueue the message read in step 1.
3. In another process, say a BPEL, I want to dequeue the message and write into a file. The filename is retrieved from one of the header properties. I want to dequeue using a stored procedure, not by using a JMS or AQ Adapter (reason being that these adapters poll the queue, and consume a message immediately. However, I want to consume the message only when there is a business need)
My questions are:
1. What kind of queue I should create in the DB (What should be its payload type...XMLType? )... I guess the answer would also determine the adapter to be used - JMS or AQ
2. How I should map the xml data read from the file in step 1 to this adapter
Any help is highly appreciated.

You are right in suggesting that I dont need to store my XML data as xml in the DB...I dont want to too :) but its just that, thats the only option I can see at this time (the other track i am exploring is :
File adapter(XML) -> Convert to opaque (base64binary) -> Enqueue opaque to JMS (aq$_jms_bytes_message) ->Dequeue Opaque -> Write file opaquely.
In this I have hit the roadblock in trying to convert XML to base64binary...maybe some custom java function is needed...anyway)
Coming back to this thread, where I am trying the following
File adapter(XML) -> Enqueue as XML to queue ->Dequeue XML -> Write file opaquely.
PS: I think its important for me to mention that I am using SOA 10.1.3.1.0
I tried the steps you gave...after creating the queue, I am trying to create a JMS adapter. But the queue I created doesnt show up in the browse window of destinations for the JMS Adapter..That had led me to infer that JMS adapter cant be used
{color:#99cc00}CREATE OR REPLACE TYPE batchupdate_row_type AS OBJECT
(update_queue_id NUMBER
,upc VARCHAR2(20)
,price1 NUMBER);
{color}
{color:#99cc00}CREATE OR REPLACE TYPE batchupdate_rec_type AS VARRAY(9999999) OF batchupdate_row_type;
CREATE OR REPLACE TYPE payload_type AS OBJECT ( payload batchupdate_rec_type);
EXECUTE DBMS_AQADM.CREATE_QUEUE_TABLE ( queue_table => 'jmsuser.batch_update_queue_table', queue_payload_type => 'payload_type');
EXECUTE DBMS_AQADM.CREATE_QUEUE ( queue_name => 'batch_update_queue', queue_table => 'jmsuser.batch_update_queue_table');
EXECUTE DBMS_AQADM.START_QUEUE ( queue_name => 'batch_update_queue'); {color}
I also needed some opinion on whether the last step of my proposed solution ( Dequeue XML -> Write file opaquely) is possible. As I want to develop a service oblivious of the structure of the file, I dont want to create a file adapter based on a particular xsd...so I want to write whatever xml I am getting from the queue....is this step possible

How to store and retrieve chinese characters

Hi, I am facing some problem in storing and retrieving of chinese characters from oracle,9i .
This is the character i am trying to store into the database
èªå¨ææ¬¾æºç½ç»
while trying to retrieve it, it shows
èª?ææ¬¾æºç½?
^ ^
you can see the weird characters like ? at some places.
here is the sample code which i can using to store and retrieve data from the database
class testInsert
public static void main(String[] args)
try {
     DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver());
     Connection conn = DriverManager.getConnection ("jdbc:oracle:thin:@172.16.6.81:1521:JFPPTDB1", "citi_user", "citi_user");
     int employee_id = 12345;
String ename = "èªå¨ææ¬¾æºç½ç»";
     oracle.jdbc.OraclePreparedStatement pstmt = (oracle.jdbc.OraclePreparedStatement)conn.prepareStatement("INSERT INTO employees (employee_id, last_name) VALUES (?, ?)");
     pstmt.setFormOfUse(2, oracle.jdbc.OraclePreparedStatement.FORM_NCHAR);
     pstmt.setInt(1, employee_id);
     pstmt.setString(2, ename);
     pstmt.execute();
pstmt.close();
pstmt = (oracle.jdbc.OraclePreparedStatement)conn.prepareStatement("SELECT last_name, employee_id from employees");
ResultSet rset = pstmt.executeQuery();
          String name = "";
          while(rset.next())
               name = rset.getString(1);
     int id = rset.getInt(2);
          System.out.println("the name is :"+name);
catch (SQLException sqe)
          System.out.println("Java SQLException caught, error message="+sqe.getMessage());
and the table in oracle is
SQL> desc employees;
Name Null? Type
LAST_NAME NVARCHAR2(10)
EMPLOYEE_ID NUMBER
I am using classes12.zip for oracle,9i. Is there any database setting that i need to know to retrieve the chinese characters?.
I have been facing this problem for quite sometime and it makes my life tough. Please help me in solving this issue.
Thanks
PD

hi, can you retrieve the chinese character from your os? When it comes to the wild code of asian character, you should focus on the database/client character setting. you may ask more about it from your dba.
have a nice weekend!

Can data be fetched from Oracle Database to ApEx websheets?

Hi,
Oracle 11g R2
ApEx 4.2.2
We are in need of giving an MRU form for the customized data by the users. The number of columns will be defined dynamically by the end user. We thought of using apex's standard tabular forms, but they cannot have dynamic columns. We also thought of having manual tabular forms using apex collections, but there is a limitation that the collection can have maximum of 50 character datatypes, 5 numeric, 5 date and 1 each for clob and blob. The number of columns at runtime may exceed these numbers. so we ruled out this. We then thought of using apex websheets. We know that the data can be fetched from Oracle database to websheet reports, but the reports cannot be edited. We know that the data grid gives option to edit the data, but I couldnt find a way to fetch the data from database to it. I understand that the data in the apex websheets can be queried from apex's meta tables apex$_ws_... views and somehow in a back door way of doing these can be updated to the business tables. But we also need to fetch the data from Oracle database to the grid. I do not want to insert into the apex$_ws tables as Oracle does not support it. Is there any other possibility?
Thanks in advance.

Natarajan

Thanks for your reply. Actually it is a data that is fully customized by the end user. These custom attributes are really stored as rows and a complex code returns them as columns at run time. So the number of columns is different user to user based on the number of rows they have.
They'd never have got that far if I'd been around...
They now want to edit them in a tabular form as well.
Well once you've implemented one really bad idea, one more isn't going to make much difference.
It rather sounds like you've got people who know nothing about relational databases or user interfaces responsible for the design of both. You need to be very, very, worried.

Want to see on screen data from oracle database using php

I am struggling on the problem of echoing data from Oracle database (9i) to the screen for viewing. For ex. the data has records from various cities. when a particular city is inputted as prompt, all the records for the that city from the table should appear through PHP. Can someone help me?

Thank you very much for giving the link. I tried and it is working. Only, I am still struggling with trying to get many fields from the database on the screen for viewing. Ex. a prompt to ask which country and which month. If I give India and December it must give all the data pertaining to India for December. This AJAX was very useful, as it gave lot of tips, but my basic query to see the data thru PHP from my database is still unsolved. Any help??

How to create longtext or blob data types in SQL using labview

Hello,
I am fairly new to SQL, and I'm using the labview database connectivity toolset. Using labview 6.1
I am using the DB Tools Create Table vi to create my tables. I want the tables to hold 1000 character strings. But the longest string that I can insert seem to be 255 characters. I think It is a limitation of the "String" data type in SQL so I need to use text or blob types. The problem is I created a control for the "Column Information" field and I see the following selections for the data type. (String, Long, Single, Double, date/time, binary). I dont see any selection for text or blobs. How do I define another data type that is not part of the selection in the control?
Thanks for any help.

I don't know about defining long text, but the equivalent of a BLOB should be the binary data type, which just holds the data you put into it without formatting it.
Try to take over the world!

How to store and retrieve a PDF form to SQL Server from LiveCycle?

My intention is to save a complete PDF form into a database and then later on retrieve this form from DB.
To do this, SQL Server has got two datatypes, image or Varbinary(max). I am able to store a PDF using "Execute SQL Statement"(I have written an Insert statement). Some value is being written into DB as well.
But when I try to retrieve this record using "Query Single Row"(I store the result to a doc variable), the retrieved PDF is of an unknown type and cannot be opened by Adobe Reader.
I am not sure if my approach is correct. Is it possible to store/retrieve a PDF form to/from a DB through LiveCycle?
If yes, please give me some guidance.

hi
am not sure
but u can use the same concept as storing image in db and retrieve..
create a blob column
parse that pdf and store into that column.
again u retrieve the content and via file io make the same name with pdf extension..

How to configure and retrieve quiz data from Captivate 7 to other server?

Hi,
I'm trying out Adobe Captivate 7 and would like to know if there's anyway for me to retrieve quiz data and display it maybe in one my company's system, such as Microsoft CRM or Sharepoint? Is there any additional settings or integration for this? So far, I've tested it to display in Acrobat by login to my own account. How if I want it to store in CRM or Sharepoint? If there's any video or guides showing on this method, it would be perfect.
Thanks.

Hi There,
Welcome To Adobe Forum.
In case of adobe captivate you can reporting data not only to acrobat server but also to an internal server e.g. WAMP server.
Please use the below link for the video tutorial for the same:
