  • BLOB data type. Will it be available in BO XIR4?

    Hi,
    Does any know if we will be able to use BLOB data type in the new coming release of BO?
    Currently the only way you can use images is copying your image files physically to a folder because BO doesn't recognize BLOB data type from the database. Is there another way around this? Please share it!
    Thanks,
    Katia.

    i dont think BO will support BLOB data

  • BLOB Data Type

    Hi
    I have stored some images in my table using blob data type. Can anyone plz tell me how to fetch those images using oracle forms.
    Thanks.

    once you base you DataBlock in forms on this table with BLOB column you will automatically get an image item in the forms for this column.
    rest is same as usual, when you do an execute query you should get the records.
    but the images you have stored in the database should be as one of the following types.
    BMP, CALS, GIF, JFIF, PICT, RAS, TIFF, TPIC.
    set the appropriate value in the property of the Image item for the "Image Format" property.

  • Using a BLOB data type in a CMP Entity Bean: Error when send large files

    I've successfully impleenting BLOB in my EJB. But the main prob is, it can only work on small file which is around 3K. Any larger files than that will caused error (refer below). I got info from a friend which is using normal JDBC call to insert a file into BLOB column that you can't use java.sql.Blob data type which will have this limitation. He suggested that by using oracle.sql.BLOB, this prob won't exist.
    The problem is I'm unable to use oracle.sql.BLOB in my CMP EJB because in the jbosscmp-jdbc.xml, I'm able to specify the normal BLOB only which is java.sql.Blob (Refer below).
             <cmp-field>
                <field-name>attachment</field-name>
                <column-name>attch</column-name>
                <jdbc-type>BLOB</jdbc-type>
                <sql-type>BLOB</sql-type>
            </cmp-field>So, how do I solve this problem? I need to store files which the size is much bigger than that. I'm using JBoss 4 as my app server and Oracle 9i as my DB. I can see that there's many ppl facing this prob, but no solution to it. Pls advise. Thanks.

  • Tg4msql - Blob Data Type Support(Oracle 8i - sql server 2000)

    hi,
    We are trying to replicate the data from oracle 8i to sql server 2000 through tg4msql.if we want to replicate the data thet contains the blob field , we are getting invalid expression in the procedure marked with error line.
    the procedure i am using is as follows
    CREATE OR REPLACE PROCEDURE INSERT_SQL
    AS
    BEGIN
    FOR VAL_CURSOR IN
    --Get the Data from the table with status 0
    SELECT rs_report_rowid FROM BIJU.rs_report where rs_report_status = 0
    LOOP
    for new_cursor in
    --get the details of the record with the row id
    select id ,name,DOB from biju.sample where rowid = val_cursor.rs_report_rowid
    LOOP
    ---insert the data from oracle to sql where the oracle data type contains blob(here photo field data type is blob).
    Error Line: insert into [email protected](id,name,photo) values(new_cursor.id,new_cursor.NAME,new_cursor.DOB);
    END LOOP;

    i want to know that tg4msql won't support the blob data type on the oracle end?we configured blob eqivalent in sql server as binary.Any help or suggestion regarding this are welcome..

    Srini,
    Support for LOB was added in v9.2. It is not supported in 8i.

  • JDBC/RMI driver does not support BLOB data type

    WLS 5.1 JDBC/RMI driver does not support BLOB data type. It is said in the Weblogic e-doc.
    I am using DataSource for database connections, meaning JDBC/RMI driver is actually producing
    database connections. I need several columns of BLOB types in my Oracle tables.
    Should I use the "JTS" driver instead in order to have the BLOB types supported ?
    Thanks for help.
    [att1.html]

    The error java.rmi.UnmarshalException seems to indicate you are somehow accessing the data-source over RMI, this seems odd. Are you running TopLink on a client and trying to connect to a WebLogic DataSource on the server?
    Maybe try connecting directly to the DataSource without going through TopLink and see if you encounter the same issue.
    You could also look at the TopLink WebLogic Examples and see how their configuration is different than your own.

  • Pdf file stored as BLOB data type on Oracle

    I store PDF file as BLOB data type on Oracle. There are cases
    where I get multiple records from the database, that means I get

    page. I tried CFContent which can display only one PDF file at a
    time but not more than one, whereas cfdocument is having problem
    converting binary data to string. I am kind of stuck.

    if by "merge" you mean 3 pdf into 1 pdf, try cfpdf (if on

  • How to use same Data Type and Length for two fields

    How to use same data type and length for two fields when using 'FOR ALL ENTRIES IN' in a select statement? For instance the select queries are :
    SELECT bukrs gjahr belnr lifnr budat bldat zlspr dmbtr waers shkzg
    FROM bsik
    INTO TABLE it_bsik
    WHERE bukrs = p_bukrs

    SELECT belnr gjahr awkey awtyp

    SELECT belnr gjahr lifnr xblnr

    WHERE belnr = it_bkpf-awkey+0(10)
    AND gjahr = it_bkpf-awkey+10(4).

    Here it gives an error in the 3rd select query that 'When you use the addition "FOR ALL ENTRIES IN itab", the fields "GJAHR" and "IT_BKPF2-AWKEY+10(4)" must have the same type and the same length.'
    Kindly clarify.
