How to add an index to a materialized view in Data Modeler 3.3

Hello everyone,
I'm looking for a how-to to add an index to a materialized view in Data Modeler 3.3.0.747, as I coudn't find a way to do it so far.
I looked here:
Relational Model
Physical Model
Oracle 11g
Materialized Views
"my_mv_name"
"INDEXES" IS NOT HERE IN THE TREE
"Tables" does not include it either
Thank you & Best regards,
Blama

Hi David,
thanks a lot. I did so and it worked, but I found a minor bug while doing so:
I marked the table as "Implement as Materialized View" and went to File->Export->DDL (for Oracle 11g).
The generated code (I checked all options in "Drop Selection") includes a row:
DROP MATERIALIZED VIEW mv_mymatview CASCADE CONSTRAINTS ;
which produces a syntax error.
Best regards,
Blama

  • How to speed up fast refresh of materialized view without primary key

    Thought I'd share this info, as I couldn't find anything on here to help me diagnose the issue:
    I had a materialized view that was taking longer to perform a fast refresh than it took to perform a complete refresh. My mview had no primary key, as the base table had no primary key.
    I created a trace file for the session and saw references to a column M_ROW$$ in my mview. Nowhere in the data dictionary could I find a reference to the m_row$$ column in my mview, but apparently it exists and is created automatically. After creating the index below, the fast refresh took 6 minutes to add 500k rows to the materialized view. (versus 4+ hours without the index) When I looked in the trace file, I noticed that for each row in the mview log, it first tries to update the mview with an UPDATE statement, then it performs an insert of the new data. Seems like it should be able to determine whether to perform an update or insert based on the DMLTYPE$$ column of the mview log. What was killing my performance was the UPDATE phase. Since I had no primary key on the mview, and no index on the m_row$$ column, the UPDATE phase was performing a full table scan of my mview for every row in the mview log. I was expecting it to be smart enough to only perform inserts, as the only transactions against the base table were inserts.
    In summary: If you have a materialized view without a primary key, create an index on the m_row$$ column of the mview, even though no such column displays in the data dictionary.
    ex:
    CREATE MATERIALIZED VIEW mv_minidrr ...
    CREATE INDEX pk_mv_minidrr ON mv_minidrr(m_row$$) ...

    Well, there indeed is a column called M_ROW$$
    Your MLOG$_EMP is nothing but the materialized view log on the base table.
    SQL> create  materialized view log on emp with rowid ;
    Materialized view log created.
    SQL> create materialized view emp_mview refresh fast on demand with rowid as select * from emp ;
    Materialized view created.
    SQL> desc mlog$_emp
    Name                                                  Null?    Type
    M_ROW$$                                                        VARCHAR2(255)
    SNAPTIME$$                                                     DATE
    DMLTYPE$$                                                      VARCHAR2(1)
    OLD_NEW$$                                                      VARCHAR2(1)
    CHANGE_VECTOR$$                                                RAW(255)
    SQL> select table_name, column_name from user_tab_columns where column_name = 'M_ROW$$' ;
    TABLE_NAME                     COLUMN_NAME
    MLOG$_EMP                      M_ROW$$
    1 row selected.

  • How to add a scroll bar within a view window ?I want to display x and y axis outside the scoll window and keep those axis static and move the graph within scroll area

    how to add a scroll bar within a view window ?I want to display x and y axis outside the scoll window and keep those axis static and move the graph within scroll area
    ananya

    Hey Ananya,
    I believe what you want to do is possible, but it will not be
    easy.  If you want to add a scroll bar that will scroll the graph
    back and forth but keep the axis set, you would want to add a
    horizontal or vertical scrollbar.  Then you would create an event
    handler for the scroll event.  You would have to manually plot
    different data within this scroll event.  Unfortunately, there is
    not really a built in way to do this with the Measurement Studio plot
    control.

    Are you trying to replicate an existing materialized view called "departments_mv1" ? That is what the implication of the arguments you are supplying.
    If it is an MV, you have to supply the DDL (in the DDL_TEXT) as well.

  • MM50 : add new column in the material view

    Dear guru.
    I need to add a new column of material master in the material view of MM50.
    Do you have a solution (exit) in order to solve my problem ?
    Thanks.

    > I need to add a new field in the MM50 transaction not in MM02.
    Der Friend,
    Pls be specific about your query. As you know MM50 is for material view extension which is a std SAP trxn to help extend the views set by standard SAP pack and if you are referring new field as a new view then it is not so easily approachable.

  • How to add UI elements dynamically in the views of webdynpro

    Hi Experts,
    Here i have a requirement where 2 text-box get added on a click of "ADD" button in the view during the execution of the Application. so is it possible to add the text-box to the view or not?
    if yes how can it be done.
    Thanks in advance
    Regards
    Lalitkumar.

    Even with these expanded requirements I wouldn't necessarily recommend dynamic UI element creation in WDDOMODIFYVIEW.
    If the UI element requirements are fairly static (2 text boxes for each push of the button), then consider using a Multi-Pane (http://help.sap.com/saphelp_nw70ehp1/helpdata/en/df/da8b412bb5b35fe10000000a1550b0/frameset.htm) or Row Repeater (http://help.sap.com/saphelp_nw70ehp1/helpdata/en/44/93d3792e8c60d6e10000000a114a6b/frameset.htm) UI element. These constructs will both create a series of UI elements based upon the number of context elements in a bound node.  Therefore if you want to generate two textboxes for each push of a button, in the button event handler you simple add another context element to the context node.  You don't need dynamic UI element creation or dynamic data binding.
    If you feel that you must use dynamic UI element creation, then first read up on the WDDOMODIFYVIEW phase model event.

  • Materialized view with date range

    hey,
    i have a Statistics Query with start date and end date and its Table table_a would be refreshed every hour....:
    e.g.
    select ...
    from table_a a, table_b b ....
    where table_a.transactiondate between start_date and end_date and ....;
    So I am wondering how to create a effective materialized view? This is a big query with mutilple tables and each table has many rows.
    I have tried to use:
    create materialized view view_a
    refresh fast
    start with sysdate next sysdate + 1/24
    as
    select a.start_date, a.end_date, ....
    from table_a a, table_b b ....
    where ....;
    Thanks.

    If you want to use FAST REFRESH, you must create a MV Log. It would be something like this:
    create materialized view log on TABLE
    with primary key including new values
    create materialized view mv_TABLE
    refresh fast
    start with sysdate next sysdate + 1/24
    as select * from TABLE
    For more info about MV:

  • Updating base table with Materialized View's data

    Hi,
    In order to update base table with MVs data, I am trying real time data transfer between two databases. One is Oracle 8i and other is Oracle 9i. I have created an updatable MV in 9i on a base table using database link. The base table is in 8i. Materialized View log is created in 8i on base table. MV has to be associated to some replication group, but I am not able to create replication group in 9i to which MV has to be associated. The required packages are not installed.
    Replication packages are to be used to create replication group are :
    /*Create Materialized View replication group*/
    BEGIN
    DBMS_REPCAT.CREATE_MVIEW_REPGROUP (
    gname => 'TEST_MV_GRP',
    master => 'TEST_DATA_LINK',
    propagation_mode => 'ASYNCHRONOUS');
    END;
    But above block is giving error.
    Can anyone suggest how to resolve this, or are there any other approaches (by not using replication packages) to update base table with MVs data ?
    Thanks,
    Shailesh

    Yes, I created link between two databases and was able to update tables on 8i from 9i database using that link.
    The error I am getting while creating replication group is :
    ORA-06550
    PLS-00201 : identifier 'SYS.DBMS_REPCAT_UTL2@'TEST_DATA_LINK' must be declared

    Is there any other approach which can be used to update base table with MVs data instead of using replication packages ?

  • MS SQL Server Indexed View in Data Modeler

    Hi All,
    I'm fairly new to Data Modeler. Tried to search the forums for this but couldn't find anything. I'm trying to figure out how to create (in a SQL Server 2008 physical model) a view with a clustered index in Data Modeler v. 3.3. Seems like it is supported per the below link, however I can't seem to find a reference to it in the application.
    http://www.oracle.com/technetwork/developer-tools/datamodeler/featurelist-167684.html
    Any help would be appreciated!
    Thanks,
    Jeff

    Hi Jeff,
    you need to create/open physical model for MS SQL Server and find view presentation there. Set the view property "Schema Binding" to yes.
    However I see some problems in definition of such index and DDL generation for view and logged a bug for that.

  • How to generate the java code of a table's data model by parsing it's FXML?

    I have know how to create FXML file that describes a table. Meanwhile, according to [Oracle Tutorial|http://docs.oracle.com/javafx/2/fxml_get_started/fxml_tutorial_intermediate.htm#CACFEHBI], it is a best practice to implement a class that defines the data model and provides methods and fields to further work with the table.

  • Materialized view with date dependencies.

    can I create a materialized view that will depend on sysdate? that means that I have to automaticaly rebuild the mv everymonth (in my case).

    The materialized view would need to be refreshed completely, but there should be no problem defining it and setting up a monthly refresh schedule.
