How to detect an AUTO_INCREMENT column in a table of PostgreSQL DB?

Hello,
I need to detect an AUTO_INCREMENT column in a table of PostgreSQL DB.
Note : PostgreSQL uses sequence number to create an AUTO_INCREMENT column.
From a ResultSetMetaData, I call the methode isAutoIncrement(int index) which returns true if the column index is AUTO_INCREMENT.
But it doesnt work..
Any idea about that?
Thank for your attention.

That's how you do it.
However, I've found that metadata calls don't always work completely with my Sybase installation. You'll have to read up on the JDBC driver and see if that feature is supported for your environment.

    Hi,
    I'm not sure if I understood what are you trying to do. But you can modify your table in a backing bean code. JSF page code for a table:
    <af:table id="product_search_results_tbl" binding="#{backingBean.boundTable}" ... />
    And a backing bean code:
    import oracle.adf.view.faces.component.core.data.CoreTable;
    public class YourBackingBean {
        private CoreTable boundTable;
        public void setBoundTable(CoreTable boundTable) {
            this.boundTable = boundTable;
        public CoreTable getBoundTable() {
            return boundTable;
       public String insertButtonAction() {
          // Bind your button action to this method and modify here your bound table
         return null;
    {code}
    Look for column modification methods in a CoreTable class documentation.

    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 insert filename as column in external table.

    I have an external table that is made up by number of different files. I would like to add a new column in the table to store the actual external filename. How can this be done?
    thanks in advanced

    That's going to be a problem, then. The ISO 8859-1 character set doesn't support that character, so you cannot store a ™ in a CHAR or VARCHAR2 column in your database.
    Potentially, you could use an NCHAR or NVARCHAR2 column, depending on your national character set. Using the national character set, though, can cause other problems, particularly for front-end applications that may not fully support those data types.
    You could also potentially change your existing character set to something that does support that character, but that may be a rather involved sort of change.

  • How to populate the organization_code column in ST table for legacy system

    Hi, dear all,
    Now I use the stage table to load the setup&transaction collection data from a non-EBS legacy system to ASCP system.
    My question is: how to populate the organization_code column in the stage table？If the source system is EBS system, maybe it's an inventory organization code. But for the non-EBS system, which value is need fo this field? keep it as blank? or assign some value for it?
    Thanks
    Edited by: 852938 on 2011-5-4 下午10:24

    I find some words in the implementation guide, it says:"To collect data from your non-Oracle ERP systems or your trading partners' systems,you model each non-Oracle ERP system or trading partner as an Oracle Applications organization and store their setup and transaction data there".
    But I can't find where to model the application organization for the legacy system.
    anyone can give some clues? Thanks in advance.

  • 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 update the COST column using another table's column

    Dear All,
    I have table:

    table odetails: ono, pno, qty

    after I update the price in parts, I need to update COST and ORDER_COST too. The orders_view does not have pno, qty, and price, the odetails_view does not have price, how can I update the COST and ORDER_COST. Please help and Thanks in advance!!!
    I wrote the update the price in parts:
    create or replace procedure change_price(ppno in parts.pno%type, pprice in parts.price%type) as

        set price = pprice

    You could add the columns to the tables and then you would need a trigger to update those columns. However, you could just as easily select the price * qty to get the cost, without creating an additional column or trigger. I have no idea what you might want to do with a global temporary table. I think you need to explain what your purpose is, before any of us can suggest the best method. Since I have already demonstrated an update with a view, I will demonstrate an update with the cost column added to the odetails table and a trigger as you asked about. Notice that you will need triggers on both tables, the one that has qty and the one that has price.

  • How to identify the source column and source table for a measure

    Does anyone have a query that I can use to positively identify the source column and source table for a cube measure in an SSAS cube?  Visual Studio shows ID, Name, and Source, but it is nearly worthless in a large cube and database.
    Also - the same for a dimension would be great.
    If no query exists for this, can someone please explain how to find the source column/table for a measure and for a dimension?
    Thanks.

    DMVs don’t expose the DataSourceView content. AMO is much better suited for object model operations like
    this than the DMVs. PowerShell is also sometimes an option, but in this case C# code would be much easier because analyzing the contents of the DataSourceView is much easier using the .Net DataSet class.
    Hope this helps.

  • How to split list of columns into 2 tables in SSIS 2012?

    Hi,
    I have 200 columns in Source. Now i want to split these columns, few into Destination A and few more columns into
    Destination B. Multi cast i tried to use, but it coping all the columns . Any help would be appreciated. Thanks in Advance.
    Lets assume  i have columns  A,B,C,D,E..
    i want to move Columns A,B,D into destination A and 
    columns A,C,D,E INTO Destination B. please help me to implement this logic?

    Hi vasu_479,
    Based on your description, you want to split columns in source table into two destination tables.
    After testing the scenario in my environment, we can use Multicast to achieve your requirement. Just as you said, the Multicast would return all columns. But we can use the method below to achieve the goal:
    If the destination tables are existing tables, we can just map column A, B and D as Input Columns to the corresponding Destination Columns in the Mapping tab for destination A. Then map column A, C, D and E in destination B.
    If the destination tables are created in the Destination component, we can modify the create table query to directly create A, B and D for destination table A, create A, C, D and E for destination table B. Then there columns would be automatically mapped
    in the Mappings pane.
    If there are any other questions, please feel free to ask.
    Thanks,
