Slicing a CLOB

I am pulling from what is equivalent to a CLOB in Oracle from a Sybase table.
Is there a way I can select only part of the CLOB for a particular id?
This CLOB has comments for all ids. However I need to be able to pull a comment for each id. I have a table in Oracle with a column name of COMMENTS.
I need to map the comment with the id it belongs too. Is it possible?

Are you working with a Sybase database? Or an Oracle database?
Does the COMMENTS table have a single row in it? Or does it have one row per "particular id"?
If there is a single CLOB with comments for all id's, you would have to parse the CLOB-- the DBMS_LOB package has a number of functions to do this assuming you are using Oracle. But this package is not available in Sybase. And you'd need to know the internal structure of your data to know how to write the logic to go about parsing the data.

  • Clob DataType, NULL and ADO

    Hello,
    First, I'm french so my english isn't very good
    I have a problem with Oracle Clob DataType. When I try to put NULL value to
    CLOB DataType with ADO, changes aren't not made.
    rs.open "SELECT ....", adocn, adOpenKeyset, adLockOptimistic
    rs.Fields("ClobField") = Null ' In this case, the Update doesn't work
    rs.update
    rs.Close
    This code works if I try to write a value which is different than Null but
    not if is equal to Null. Instead of having Null, I have the old value
    (before changes), the update of the field doesn't work.

    I experience the same, did you find a solution to your problem?
    Kind regards,

  • How to load a client file in a clob using sqlcl

    How to load a client file in a clob using sqlcl

    You don't "load" jars. If it's on the classpath, you can obtain individual resources from it using various methods on either Class or ClassLoader. Do you mean "how to add a jar to the classpath at runtime"? Can't be done without using a classloader, typically URLClassLoader or a subclass thereof. Why you want to not use the proven method is beyond me. Presumably because you don't understand classloading. In which case, forget it.

  • XML data 32K into CLOB

    Hi all,
    I am trying to use UTL_FILE.PUT_LINE to output an XML file. This xml file is the result of a select query. Hence converting the result of the select query into xml format using dbms_xmlgen.getxml and storing it in a variable. But the resultant xml data > 32k . What would be the best way to store it in variable? When using CLOB datatype, getting a numeric value error.
    Thanks in advance.

    As you didn't post the code, nor included a four digit database version, you are asking someone to look in a crystal ball.
    Sorry, they are out for repair.
    Also the XDB forum would be more appropriate.

  • How to find out list of clob/blob tables in a schema

    Hi,
    I have tricky situation...i have 119 tables out of which 11 tables are clob/blob tables...is there any view where i can find out list of tables are clob/blob tables? (at schema level view means user_<>)
    -- Raman.

    USER_TAB_COLS includes the data type, column name, and table name for each column in each table in the system. You could query that looking for columns with a DATA_TYPE of CLOB or BLOB. If some tables have multiple LOB columns and you want them to appear only once, you'd have to throw a DISTINCT on the table name.

  • Can't fetch clob and long in one select/query

    I created a nightmare table containing numerous binary data types to test an application I was working on, and believe I have found an undocumented bug in Oracle's JDBC drivers that is preventing me from loading a CLOB and a LONG in a single SQL select statement. I can load the CLOB successfully, but attempting to call ResultSet.get...() for the LONG column always results in
    java.sql.SQLException: Stream has already been closed
    even when processing the columns in the order of the SELECT statement.
    I have demonstrated this behaviour with version 9.2.0.3 of Oracle's JDBC drivers, running against Oracle 9.2.0.2.0.
    The following Java example contains SQL code to create and populate a table containing a collection of nasty binary columns, and then Java code that demonstrates the problem.
    I would really appreciate any workarounds that allow me to pull this data out of a single query.
    import java.sql.*;
    This class was developed to verify that you can't have a CLOB and a LONG column in the
    same SQL select statement, and extract both values. Calling get...() for the LONG column
    always causes 'java.sql.SQLException: Stream has already been closed'.
    CREATE TABLE BINARY_COLS_TEST
    PK INTEGER PRIMARY KEY NOT NULL,
    CLOB_COL CLOB,
    BLOB_COL BLOB,
    RAW_COL RAW(100),
    LONG_COL LONG
    INSERT INTO BINARY_COLS_TEST (
    PK,
    CLOB_COL,
    BLOB_COL,
    RAW_COL,
    LONG_COL
    ) VALUES (
    1,
    '-- clob value --',
    HEXTORAW('01020304050607'),
    HEXTORAW('01020304050607'),
    '-- long value --'
    public class JdbcLongTest
    public static void main(String argv[])
    throws Exception
    Driver driver = (Driver)Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
    DriverManager.registerDriver(driver);
    Connection connection = DriverManager.getConnection(argv[0], argv[1], argv[2]);
    Statement stmt = connection.createStatement();
    ResultSet results = null;
    try
    String query = "SELECT pk, clob_col, blob_col, raw_col, long_col FROM binary_cols_test";
    results = stmt.executeQuery(query);
    while (results.next())
    int pk = results.getInt(1);
    System.out.println("Loaded int");
    Clob clob = results.getClob(2);
    // It doesn't work if you just close the ascii stream.
    // clob.getAsciiStream().close();
    String clobString = clob.getSubString(1, (int)clob.length());
    System.out.println("Loaded CLOB");
    // Streaming not strictly necessary for short values.
    // Blob blob = results.getBlob(3);
    byte blobData[] = results.getBytes(3);
    System.out.println("Loaded BLOB");
    byte rawData[] = results.getBytes(4);
    System.out.println("Loaded RAW");
    byte longData[] = results.getBytes(5);
    System.out.println("Loaded LONG");
    catch (SQLException e)
    e.printStackTrace();
    results.close();
    stmt.close();
    connection.close();
    } // public class JdbcLongTest

    The problem is that LONGs are not buffered but are read from the wire in the order defined. The problem is the same as
    rs = stmt.executeQuery("select myLong, myNumber from tab");
    while (rs.next()) {
    int n = rs.getInt(2);
    String s = rs.getString(1);
    The above will fail for the same reason. When the statement is executed the LONG is not read immediately. It is buffered in the server waiting to be read. When getInt is called the driver reads the bytes of the LONG and throws them away so that it can get to the NUMBER and read it. Then when getString is called the LONG value is gone so you get an exception.
    Similar problem here. When the query is executed the CLOB and BLOB locators are read from the wire, but the LONG is buffered in the server waiting to be read. When Clob.getString is called, it has to talk to the server to get the value of the CLOB, so it reads the LONG bytes from the wire and throws them away. That clears the connection so that it can ask the server for the CLOB bytes. When the code reads the LONG value, those bytes are gone so you get an exception.
    This is a long standing restriction on using LONG and LONG RAW values and is a result of the network protocol. It is one of the reasons that Oracle deprecates LONGs and recommends using BLOBs and CLOBs instead.

  • Not able to display and search on CLOB attribute in default search screen

    Hi,
    My requirement:
    I have three VARCHAR attributes and 1 CLOB attribute. i need to search the values on these 4 attributes.
    Created View crieteria on these 4 attributes and created default ADF search screen. but not able to add the CLOB attribute as search attribute.
    is there any solution for this or we can't search on CLOB attribute.
    FYI: i have created Converter using ClobDomain and and using this converted for editing the CLOB data.
    If i try adding the CLOB attribute in view criteria with ClobDomain and not able to see that attribute on search panel.
    Please help on this.
    Thanks in advance!!
    Thanks & Reagrds,
    Madhu

    Madhu, please tell us your jdev version!
    The search is done on the DB (query) so the converter is not used. To search clob columns you can use special SQL statements called contains or catsearch. These are using special index to find the data in blob or clob columns.
    Check my blog on how to integrate this into VC: http://tompeez.wordpress.com/2011/08/21/extending-viewcriteria-to-use-sql-contains-4/

    I have an issue with the tables having a CLOB datatype field.
    When executing a simple query on a table with a column of type CLOB it returns error [POL-2403] value too large for column.
    SQL> desc od_stock_nbcst_notes;
    Name Null? Type
    OD_STOCKID N NUMBER
    NBC_SERVICETYPE N VARCHAR(40)
    LANGUAGECODE N VARCHAR(8)
    AU_USERIDINS Y NUMBER
    INSERTDATE Y DATE
    AU_USERIDUPD Y NUMBER
    MODIFYDATE Y DATE
    VERSION Y SMALLINT(4)
    DBUSERINS Y VARCHAR(120)
    DBUSERUPD Y VARCHAR(120)
    TEXT Y CLOB(2000000000)
    NBC_PROVIDERCODE N VARCHAR(40)
    SQL> select * from od_stock_nbcst_notes;
    [POL-2403] value too large for column
    Checking deeply, some of the rows have got the data of the CLOB column moved in another column of the table.
    When doing select length(nbc_providercode) the length is bigger than the datatype of the field (varchar(40)).
    When doing substr(nbc_providercode,1,40) to see the content of the field, a portion of the Clob data is retrieved.
    SQL> select max(length(nbc_providercode)) from od_stock_nbcst_notes;
    MAX(LENGTH(NBC_PROVIDERCODE))
    162
    Choosing one random record, this is the stored information.
    SQL> select length(nbc_providerCode), text from od_stock_nbcst_notes where length(nbc_providerCode)=52;
    LENGTH(NBC_PROVIDERCODE) | TEXT
    -------------------------+-----------
    52 | poucos me
    SQL> select nbc_providerCode from od_stock_nbcst_notes where length(nbc_providerCode)=52;
    [POL-2403] value too large for column
    SQL> select substr(nbc_providercode,1,40) from od_stock_nbcst_notes where length(nbc_providercode)=52 ;
    SUBSTR(NBC_PROVIDERCODE
    Aproveite e deixe o seu carro no parque
    The content of the field is part of the content of the field text (datatype CLOB, containts an XML)!!!
    The right content of the field must be 'MTS' (retrieved from Central DB).
    The CLOB is being inserted into the Central DB, not into the Client ODB. Data is synchronized from CDB to ODB and the data is reaching the client in a wrong way.
    The issue can be recreated all the time in the same DB, but between different users the "corrupted" records are different.
    Any idea?

    Hello,
    I am using Oracle 11.2, I would like to use SQL to update one column based on values of other rows at the same table. Here are the details:
    create table TB_test (myId number(4), crtTs date, updTs date);
    insert into tb_test(1, to_date('20110101', 'yyyymmdd'), null);
    insert into tb_test(1, to_date('20110201', 'yyyymmdd'), null);

    insert into tb_test(2, to_date('20110902', 'yyyymmdd'), null);
    After running the SQL, I would like have the following result:
    1, 20110101, 20110201
    1, 20110201, 20110301
    1, 20110301, null
    2, 20110901, 20110902
    2, 20110902, null
    Thanks for your suggestion.How do I ask a question on the forums?

    using dbms_lob package is not helping. Either DB stops responding. Or the Observation field ( which has max length >300000) can not be loaed into a CLOB variable.

  • Help!!urgent!!can not insert/update clob:the row containing the lob is not locked

    Hi,
    could you do me help?
    i can not insert a string into a oracle clob field, it echo as:
    ORA22920 row containing the lob value is not locked. ORA 06512 at "SYS.DBMS_LOB" line 708
    ORA 06512 at line 1;
    what its means? please.
    my table defined as : create table clob1(id number(5),mclob clob default empty_clob()); the id is create by a sequece of test_sequence automaticly.
    my code as belows:
    import java.io.*;
    import java.sql.*;
    //import oracle.sql.*;
    public class test4 {
    public static void main(String args[]) {
    String url_String

    Hi,
    To avoid ORA-22920 error while selecting lob column, use the 'for update' clause in the select statement like :
    query = "select * from clob1 where id="+currval+" FOR UPDATE" ;
    This should solve the problem. However, after fixing this, you might get the error :
    java.sql.SQLException: ORA-1002: fetch out of sequence
    I got this error when testing your code. To avoid this error, before executing 'select ... for update' statement Set AutoCommit to OFF, like :
    query = "select * from clob1 where id="+currval+" FOR UPDATE" ;
    con.setAutoCommit(false);
    rs =stmt.executeQuery(query);
    Hope that Helps,

  • The ADO NET Source was unable to process the data. ORA-64203: Destination buffer too small to hold CLOB data after character set conversion.

     We developed a SSIS Package to pull the data From Oracle source to Sql Server 2012. Here we used ADO.Net source to pull the records from Source but getting the below error after pulling some 40K records.
      [ADO NET Source [2]] Error: The ADO NET Source was unable to process the data. ORA-64203: Destination buffer too small to hold CLOB data after character set conversion.
    [SSIS.Pipeline] Error: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED. 
     The PrimeOutput method on ADO NET Source returned error code 0xC02090F5. 
     The component returned a failure code when the pipeline engine called PrimeOutput(). 
    The meaning of the failure code is defined by the component, 
    but the error is fatal and the pipeline stopped executing.

    Hi,
      Tried both....
      * Having schema type as Nvarchar(max). - Getting the same error.
      * Instead of ADO.Net Source used OLEDB Source with driver as " Oracle Provide for OLE DB" Getting error as below.
           [OLE DB Source [478]] Error: SSIS Error Code DTS_E_OLEDBERROR.  An OLE DB error has occurred. Error code: 0x80004005.
