  • How to identify all the child tables referencing a master table

    Hi,
    How to identify all the child tables referencing a master table.
    Could you please help me...
    Thanks in advance...

    Hi!
    You may use this query:
    SELECT master.table_name, child.table_name
    FROM   user_constraints master, user_constraints child
    WHERE  master.table_name IN ('REGIONS')
      AND  master.constraint_name = child.r_constraint_name

  • How to identify Facts

    Hi,
    My project is a EDW project (NON-ERP to ERP). Right now we are in design phase. I need to identify the facts by seeing the reports (BO). The reports are in different forms like excel, PPT, Graphs, Charts. So I would like to know what all needs to taken into consideration while identifying Facts.

    data warehousing, a fact table consists of the measurements, metrics or facts of a business process. It is often located at the centre of a star schema or a snowflake schema, surrounded by dimension tables.
    Fact tables provide the (usually) additive values that act as independent variables by which dimensional attributes are analyzed. Fact tables are often defined by their grain. The grain of a fact table represents the most atomic level by which the facts may be defined. The grain of a SALES fact table might be stated as "Sales volume by Day by Product by Store". Each record in this fact table is therefore uniquely defined by a day, product and store. Other dimensions might be members of this fact table (such as location/region) but these add nothing to the uniqueness of the fact records. These "affiliate dimensions" allow for additional slices of the independent facts but generally provide insights at a higher level of aggregation (a region contains many stores).

  • How to identify Changes in ALV Table

    Hi All,
    I am using the ALV Component to show a table. Now I would like to identify the changes made to my table. I have tried to use the Change Log of the Context, but the changes to the corresponding context node are not logged in the Change Log (most likely due to the fact that the Context Node is mapped to the ALV Component).
    Now, my question is: How can I identify the changes made in the ALV Table?
    THANKS, Johannes

    you will have to have a NODE which you send to the ALV SET_DATA( ) method
      data:
        lr_salv_wd_table type ref to iwci_salv_wd_table.
      data:
        lr_salv_wd_table_usage type ref to if_wd_component_usage.
    lr_salv_wd_table_usage = wd_this->wd_cpuse_salv_wd_table( ).
      if lr_salv_wd_table_usage->has_active_component( ) is initial.
        lr_salv_wd_table_usage->create_component( ).
      endif.
    lr_salv_wd_table = wd_this->wd_cpifc_salv_wd_table( ).
    lr_node = wd_context->get_child_node( 'DATA' ).
    lr_salv_wd_table->set_data( lr_node ).
    enable contextlog
    ... lr_context->enable_context_change_log( ).
    lr_node = wd_context->get_child_node( 'DATA' ).
    lr_context = lr_node->get_context( ).
    lt_context_changelist = lr_context->get_context_change_log().

  • How to identified the size of table logging (SCU3)

    hi SAP Expert,
    currently i'm activating the table logging via parameter REC\CLIENT = ALL, understand that this will accumulate the log times to times, is there anyway i can identified how big is the log file already? since i'm concern the log files would make my hardisk full. thanks for any respon.
    Regards
    Hariyono

    Table logging write to table DBTABPRT, just check the size of the table in DB02 (or number of entries in SE16) you can track the growth of the table and wipe the contents once the data is been consumed by whoever requested it.
    You can check in DB02 in what tablespace the table is located and make sure that theres enough space in the filesystem for the table to grow without causing inconvenients.

  • How to identify current row in table from selectOneChoice compact mode

    Hi,
    I have an af:table in which one of the columns is selectOneChoice in compact mode.  Upon selecting item in this selectOneChoice, valueChangeListener is triggered and do some work based on that row.  However, my issue is that it's hard to identify the current row since the selectOneChoice is in compact mode.  If the selectOneChoice is not in compact mode, when user selects item in selectOnechoice, selectionListener of af:table is triggered to identify the current row.  But if selectOneChoice is in compact mode, user is able to select from selectOneChoice and valueChangeListener is triggered before selectionListener of af:table is triggered.  Hence, not able to identify current row. 
    As a not so ideal workaround, I tried to put the row identifier (in my case, it's DetailSeq) in shortDesc, and get it from there.  But users is complaining seeing this not user friendly in shortDesc/hintText.  I tried to put DetailSeq as the id of the selectOneChoice, but it didn't work (Cannot get Id of selectOneChoice in table)
    <af:table>
      <af:column headerText="Action" id="c5" width="30">
            <af:selectOneChoice id="a${row.DetailSeq}" autoSubmit="true" valueChangeListener="#{viewScope.backing_requestOverview.onSelectAction}" label="Action" mode="compact" shortDesc="#{row.DetailSeq}">
                <f:selectItems value="#{backing_requestOverview.requestActionsMap[row.StatusUid]}" id="si333"/>
                </af:selectOneChoice>
        </af:column>
    </af:table>
    In the valueChangeListener:
      public void onSelectAction(ValueChangeEvent valueChangeEvent) {
    RichSelectOneChoice actionChoice = (RichSelectOneChoice)valueChangeEvent.getComponent();
    LOGGER.info("Short Desc: " + actionChoice.getShortDesc());
            LOGGER.info("Component Id: " + actionChoice.getId());
    Any advice?
    Thanks
    -Mina

    Hi,
    what about using an f:attribute tag to add the "DetailSeq" to the component. Should work similar to the shortDesc but is invisible. You can then get this attribute value by its name among the component attributes

  • How to identify missing records in a single-column table?

    How to identify missing records in a single-column table ?
    Column consists of numbers in a ordered manner but the some numbers are deleted from the table in random manner and need to identify those rows.

    Something like:
    WITH t AS (
               SELECT 1 ID FROM DUAL UNION ALL
               SELECT 2 ID FROM DUAL UNION ALL
               SELECT 3 ID FROM DUAL UNION ALL
               SELECT 5 ID FROM DUAL UNION ALL
               SELECT 8 ID FROM DUAL UNION ALL
               SELECT 10 ID FROM DUAL UNION ALL
               SELECT 11 ID FROM DUAL
    -- end of on-the-fly data sample
    SELECT  '[' || (id + 1) || ' - ' || (next_id - 1) || ']' gap
      FROM  (
             SELECT  id,
                     lead(id,1,id + 1) over(order by id) next_id
               FROM  t
      where id != next_id - 1
    GAP
    [4 - 4]
    [6 - 7]
    [9 - 9]
    SQL> SY.
    P.S. I assume sequence lower and upper limits are always present, otherwise query needs a little adjustment.

  • How to identify migrated rows on a table

    Hi, folks,
    I'm wondering how to identify migrated rows on a table.
    I understand that ANALYZE generates data into CHAINED_ROWS. The Oracle document implies that this table has both CHAINED ROWS and MIGRATED ROWS. FYI:
    http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14231/general.htm#sthref1881

  • 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.

  • DWH: how do you analyze fact and dimension tables

    Hi,
    I was wondering how you analyze your fact and dimension tables.
    Our fact table is partitioned per month. Each partition contains 4M rows and is 270 MB large. We are using 9 dimensions, 6 have about 50'000 rows (2MB), 1 about 1M rows (50MB) and 2 about 3M rows (200MB). All tables are compressed. The version of Oracle we are using is 9.2.0.5.
    What I was wondering is how you would, using dbms_stats, analyze the fact and dimension tables. Which percentage would you analyze? On which column would you build histograms?

    nope, but i could copy-paste the URL or I could copy-paste the entire thread from the other forum. Id did the one that made more sense to me.
