OCCI: How to get tablename of column described by metadata?

Hi there,
I need to determine the tablename of columns, which were selected in a select-command. Using the getColumnListMetaData() function from the ResultSet class
I get the metadata for each column of the select-command.
vector<MetaData> data=rset->getColumnListMetaData();
data.getString(MetaData::ATTR_NAME)
data[i].getInt(MetaData::ATTR_DATA_TYPE)
data[i].getInt(MetaData::ATTR_DATA_SIZE)
data[i].getInt(MetaData::ATTR_PRECISION)
data[i].getInt(MetaData::ATTR_SCALE)
The 5 attributs above can be applied on the MetaData object which only allows to determine the columnname... Do I have to analyse the sql-command or is there an easier way?
Thanks in advance
Johannes

You do not want to call the SP as you may affect some data in the DB.
Instead, to get the resulting schema from Sp:
SELECT * FROM sys.dm_exec_describe_first_result_set ('owner.sprocName', NULL, 0) ;
To Get Parameters from SP (filter out your SP from list):
execute [sys].[sp_sproc_columns]

    Hi,
    looks like you are on Infomation Builders, correct? If yes through which adapter and to what DB are you connecting?? in an R3/BW system you can do the folowing:
    "(ABAP)
    SELECT DISTINCT FIELDNAME
    FROM DD03L
    WHERE TABNAME = '/BIC/QPERSON'
      AND AS4LOCAL = 'A'
      AND KEYFLAG = 'X'
    ORDER BY 1
    Another option is goto directly to the RDBMS; in this case let me which one are you using
    hope this helps...

  • How to get the dynamic columns in UWL portal

    Hi All,
    I am working on UWL Portal. I am new to UWL. I have down loaded uwl.standard XML file and costomized for getting the  values for "select a Subview" dropdown and I am able to see the values in the dropdown. Now my requirement is to get the dynamic columns based on the selection from dropdown value.
    can any body suggest on how to get the dynamic columns in UWL portal.

    Hi  Manorama,
    1) If you have already created a portal system as mentioned in following blog
                  /people/marcel.salein/blog/2007/03/14/how-to-create-a-portal-system-for-using-it-in-visual-composer
    2) If not, then try to create the same. Do not forgot to give the Alias name .
    3) After creating a system, log on to the VC, Create one iView.
    4) Now Click on "Find Data" button from the list which you can view in right side to Visual composer screen.
    5) After clicking on "Find Data" button, it will ask for System. If you have created your system correctly and Alias name is given properly, then your mentioned Alias name is appeared in that list.
    6) Select your system Alias name and perform search.
    7) It will display all the BAPIs and RFCs in your systems.
    8) Select required BAPI and develop the VC application.
    Please let me know if you any further problems.

  • How to get invoice status column in ap_invoice_all table

    how to get the invoice_status column like "NEEDS RE VALIDATION"      in account payables tables.

    The invoice approval status does not come from any table / lookup.
    Instead, Oracle builds it by calling the ap_invoices_pkg.get_approval_status function.
    You can also call it by passing invoice_id, payment_status_flag and invoice_type_lookup_code.
    All these 4 columns are present on the ap_invoices_all record.

  • How to get table data column by column dynamically

    Hi ,
    first of all
    i have something like this
    cursor sys_cursor is
    select * from sys.all_objects;
    v_data varchar2(200);
    fetch sys_cursor
    into v_owner, v_object_name, v_subobject_name, v_object_id, v_data_object_id, v_object_type, v_created, v_last_ddl_time, v_time_stamp, v_status, v_temporary, v_generated, v_secondary;
    v_data := v_owner || ' ' || v_object_name || ' ' || v_subobject_name || ' ' ||

    it is ok for "sys.all_objects" but i need to modify this for all tables
    so , i need to know column names of table and type of it and value of it
    then i need to get column values by one by and encrypt it.
    i used dbms_sql and succeed to find column name and type
    however , i couldnt get the values.i can't use dbms_sql.column_values because i find column type dynamically.
    what can i do?
    how can i get table data by row
    and then for each row , i need to get values of columns by one by and encrypt those values.
    any idea is appriciated.
    thanks
    Aykut

    Dynamic SQL is the solution. Right from getting the column names, their data types to passing the string to encrypt function that you have.
    You will need to handle datatypes like LONG, LOB etc... as they cannot be concatenated with strings.
    Also, you need to manage dates and numbers.
    Obviously this would be very complicated code.
    Even if you decide to code the procedure to encrypt tables one by one, still you need to make this procedure dynamic to handle above situations.

  • How to get Tablename by using only Column Name in Schema?

    Hi,
    Here I need a small information. I am looking for the TableName based on Column Name.
    I know the Column name but not in which Table that Column belongs? So is there any way to look the Table Name by giving Column Name as an Input parameter in Oracle Schema.
    If anybody have the answer please help me out.I appriciate your help.
    Thanks,

    Srikanth,
    The three data dictionary views:
    <ol>
    <li>USER_TAB_COLUMNS</li>
    <li>ALL_TAB_COLUMNS</li>
    <li>DBA_TAB_COLUMNS</li>
    </ol>
    Contain both the column name and the table name (among other things).
    More information can be found in the Oracle documentation, in particular the Oracle Database Reference.
    All Oracle documentation can be accessed from here:

  • How to get auto generated column in spring jdbc

    Hi guys ,
    I am using springJDBC and sybase db.
    I think what i am facing is a standard problem but whatever support i am getting from google is not working.
    My problem is :
    "While inserting values in database one colum is autogenerated .....how do i get the value of that column??"
    FYI,
    I have tried using the following code :
    "final String INSERT_SQL = "insert into my_test (name) values(?)";
    final String name = "Rob";
    KeyHolder keyHolder = new GeneratedKeyHolder();
    jdbcTemplate.update(
    new PreparedStatementCreator() {
    public PreparedStatement createPreparedStatement(Connection connection) throws SQLException {
    PreparedStatement ps =
    connection.prepareStatement(INSERT_SQL, new String[] {"id"});
    ps.setString(1, name);
    return ps;
    keyHolder);
    // keyHolder.getKey() now contains the generated key"
    but i am getting this error : "java.lang.AbstractMethodError: com.sybase.jdbc2.jdbc.SybConnection.prepareStatement(Ljava/lang/String;I)Ljava/sql/PreparedStatement"
    I think this code works well with Oracle but not with sybase .........does anyone know the solution of this problem .......and by "this problem" i mean how to retrieve auto generate value in spring jdbc ...........without using SimpleJdbcInsert class

    Looking at the previous post it doesn't look like a Spring issue.
    You are using a JDBC driver which does not support getting generated keys so you have 2 choices:
    - Use a different driver that supports generated keys
    - Get the generated key by issuing some vendor specific SQL e.g. 'select @@identity' for SQL server
