DB2 V10 and column distributions

Hi all,
since a few some of our customers work with DB2 Version 10 in production.
And now it seems that the explain functionality in the transaction sbde works a little bit fuzzy if it displays the column distributions.
Here comes an example on table ICLCCEVENTB:
column cardinality:
|Column Name|Cardinality|
|CLIENT     |         1 |
|ACTIVE     |         1 |
|CCEVENT    | 6.617.921 |
|ROLE       |        22 |
|BPARTNER   | 2.164.627 |
|PHONEADDR  |         1 |
|PHONEID    |         1 |
|CHANGETIME | 1.031.781 |
|CHANGEDBY  |     3.840 |
|DELETED    |         3 |
|NAME       | 1.451.192 |
|DESCRIP    | 1.451.192 |
|REFERENCE  |         1 |
indexes:
|Index          |Index Columns                      |1st Key|   Full Key|
|ICLCCEVENTB~0  |CLIENT,ACTIVE,CCEVENT,ROLE,BPARTNER|     1 |14.335.378 |
|ICLCCEVENTB~003|CLIENT,CCEVENT                     |     1 | 6.617.921 |
column distributions.
|Column Group                       |Low|High|Cardinality|Freq[%]|Type       |                                   
|CLIENT,ACTIVE,CCEVENT,ROLE,BPARTNER|   |    |14.335.378 |    0,0|Cardinality| => obsolete, Full Key Index ~0    
|CLIENT,ACTIVE,CCEVENT,ROLE,BPARTNER|   |    |14.269.582 |    0,0|Cardinality| ? CLIENT,ACTIVE, CCEVENT, ROLE    
|CLIENT,ACTIVE,CCEVENT,ROLE,BPARTNER|   |    | 6.617.921 |    0,0|Cardinality| ? CLIENT,ACTIVE, CCEVENT          
|CLIENT,ACTIVE,CCEVENT,ROLE,BPARTNER|   |    |         1 |    0,0|Cardinality| ? CLIENT,ACTIVE                   
|CLIENT                             |xxx|xxxx|         1 |  100,0|Frequency  | ok                                
But if i look into the catalog, i get the same data:

  • Question regarding Dashboard and column prompt

    My question regarding Dashboard and column prompt:
    1) Dashboard prompt usually work with only for columns which are in subject area. In my report I've created some of the columns which are based on other columns. Like I've daysNumber column that is based on two other columns, as it calculates the difference of two dates. When I create dashboard prompt I can't find this column there. I need to make a prompt on this column.
    2)For one of the column I've only two values 1 and 0. When I create prompt for this column, is it possible that in drop down list It shows 'Yes' for 1 and 'No' for 0 and still filter the request??

    Hi Toony,...
    I think there was another way of doing this...
    In the dashboard prompt go to Show option > select SQL Results from dropdown.
    There you need to write your Logical SQL like...
    SELECT CASE WHEN 1=0 THEN PERIODS.YEAR ELSE difference of date functionality END FROM SubjectAreaName
    Here.. Periods.Year is the column which is already exists in repository's presentation layer..
    and difference of date functionality is the code or formula of column which you want to show in drop-down...
    Also write the CASE WHEN 1=0 THEN PERIODS.YEAR ELSE difference of date functionality END code in fx of that prompt.
    I think it helps you in doing this..
    Just check and inform me if it works...
    Thanks & Regards

  • How can i open a PDF bank statement in numbers so that the rows and columns contain properly aligned data from statement?

    how can i open a PDF bank statement in "numbers" so that the rows and columns contain properly aligned data from statement?

    Numbers can store pdfs pages or clippings but does not directly open pdf files.  To get the bank statement into Numbers as a table I would open the bank statment in Preview (or Skim) or some pdf viewer.
    Then hold the option key while selecting a column of data.
    Then copy
    Then switch to numbers and paste the column into a table
    Then repeat for the other columns in the pdf document
    It would be easier (in my opinion) to download the QFX or CSV version from your bank

  • How to get table and column names thats being used in SQL , that's generating all my reports on SSRS.

    Good day,
    I searched through the forum and cant find anything.
    I have around 300 published reports on SSRS and we are busy migrating to a new system.
    They have already setup their tables on the new system and I need to provide them with a list of table names and column names that are being used currently to generate the 300 reports on SSRS.
    We use various tables and databases to generate these reports, and will take me forever to go through each query to get this info.
    Is it at all possible to write a query in SQL 2008 that will give me all the table names and columns being used?
    Your assistance is greatly appreciated.
    I thank you.
    Andre.

    There's no straightforward method for that I guess. There are couple of things you can use to get these details
    1. query the ReportServer.dbo.Catalog table
    for getting details
    you may use script below for that
    http://gallery.technet.microsoft.com/scriptcenter/42440a6b-c5b1-4acc-9632-d608d1c40a5c
    2. Another method is to run the reports and run sql profiler trace on background to retrieve queries used.
    But in some of these cases the report might be using a procedure and you will get only procedure. Then its upto you to get the other details from procedure like tables used, columns etc

  • How to insert data into datagrid dynamically and also programatically with data and column names being retrived from a xml file..

    iam not able to insert data into datagrid corresponding to the column names..as iam inserting both data and column names programatically..ie iam not able to co relate the data with the column names.plzzz help me asap

    A DataGrid is row-based rather than cell-based with each row
    corresponding to an item in an underlying collection (specified in the
    dataProvider property). In order to add data to a DataGrid you
    manipulate the underlying collection, rather than the grid directly.
    Based on the limited description of your problem I would imagine you
    would need to create dynamic objects with property names that correspond
    to the dataFields of your dynamically created datagrid columns.
    So if you had created columns with dataFields "alpha", "beta" and
    "gamma" on your datagrid, you could create an item in your grid by
    adding the following object to your dataProvider:
    var gridItem : Object = new Object();
    gridItem.alpha = "alphaValue";
    gridItem.beta = "betaValue";
    gridItem.gamma = "gammaValue";

  • How do I delete multiple rows and columns in an image?

    I am looking into how digital SLRs extract video data from a CMOS sensor. To give an example, the GH1 from Panasonic can record video at 1920 x 1080 from a 12 MPixel sensor that, say, is 4000 horizontal x 3000 vertical. How they do that seems to be not in the public domain, but there have been a few guesses (see http://www.dvxuser.com/V6/showthread.php?t=206797 and http://luminous-landscape.com/forum/index.php?showtopic=38713).
    One approach would be to simply read every second row of sensor pixels (1500 rows read from the original 3000) and once you have those in memory, delete every second column (2000 columns left). You would end up with a 2000 x 1500 image which could then be resampled to 1920 x 1080.
    I'd like to simulate what the camera appears to be doing, by generating a 4000 x 3000 test image and then asking Photoshop CS4 to delete the appropriate rows and columns. It may not necessarily be every second row; the Canon 5DMk11 appears to read every third row, so I may need to delete two out of every three rows.
    Can Photoshop do that sort of thing? If so, how?

    Thanks for the suggestions. Yes, I did take a detailed look at your images, but they weren't 100% convincing because it wasn't clear just what was happening. And Adobe's explanation, after reading it again, explains nothing at all to someone who doesn't know how Nearest Neighbor works.
    But you are correct -- Nearest Neighbor does effectively delete pixels. I proved it with the attached 6 x 6 image of coloured pixels (the tiny midget image right after this full stop -- you'll have to go to maximum zoom in PS to see it).
    These are the steps to delete every second row and then every second column.
    1. Select Image > Image Size.
    2. Set Pixel Dimensions > Height to half the original (in this case set to 3 pixels).
    3. Set Resample Image to Nearest Neighbor.
    4. Click OK and the image shoould now consist of three vertical white strips and three vertical Green-Red-Blue stripes.
    5. Repeat steps 1-4, but this time set Pixel Dimensions > Width to half the original (in this case set to 3 pixels). The image should now consist of three horizontal stripes Green-Red-Blue.
    Just to make sure the method worked for every third pixel, I repeated the above steps but with 2 pixels instead of 3 and obtained the correct White-Green, White-Green pattern.
    I resampled the Height and Width separately for the test so that I could see what was happening. In a real example, the height and width can be changed at the same time in the one step, achieving the same results as above.
    Finally, how to explain how Nearest Neighbor works in the simple cases described above?
    Division by 2
    In the case of an exact division by two (pixels numbered from top leftmost pixel), only the even numbered rows and columns remain. To put it a different way, every odd numbered row and column are deleted.
    Division by 3
    Only rows and columns 2, 5, 8, 11... remain.
    Division by N
    Only rows and columns 2, 2+N, 2+2N, 2+3N... remain.
    To put it simply, a resample using Nearest Neighbor (using an exact integer multiple) keeps every Nth row and column, starting from number two. The rest are deleted.

  • Lock rows and columns header in a table view report. It is possible?

    hi,
    I have a Dashboard that displays a report in "Table View" with many rows and columns.

    This would have blocked such headers that contain attributes and measures and to browse the report (eg with a scroll bar) had always viewed the headers.
    Can you help me?

  • Is it possible to switch the rows and columns?

    Is it possible to switch the rows and columns of a table? The reason I ask is that it would be easier for me to input the data with the number at the top of a column and the fields going down. But it would be easier to read the data with the number on the left and the fields going to the right. Is it possible to switch a table in this way?

    It sounds to me as though you wish to transpose a table so that the original is changed from rows to columns and from columns to rows, as in the following:
    Table 1
        A   B   C
    ========
    1   o   p   q
    2   r   s   t
    3   u   v   w
    Table 2
        A   B   C
    ========
    1   o   r   u
    2   p   s   v
    3   q   t   w
    You are right - it would be nice to have a menu item to magically transpose a selected block of cells. But there isn't one. So...
    One way to solve this is to use the index() and transpose() functions to accomplish row and column cell transposition. If you are going to use a 1:1 cell correspondence and change the header columns and rows also, you can use this:
       =INDEX(TRANSPOSE(Table # :: <range>),ROW(),COLUMN())
    where Table # and <range> is substituted as in the following fashion:
       =INDEX(TRANSPOSE(Table 1 :: $A$1:$C$3),ROW(),COLUMN())
    Create a second table. Copy the modified formula above with the appropriate substitutions, select the range you wish to have your transposition inserted into (must match the transposed cell dimensions of the original range), paste the forumula and voila! the cells will be transposed.
    Cautions:
    o The target table must match the swapped cell length and width dimension. For example, if the original data range is 6 columns wide by 4 rows deep, then the corresponding table or range to hold the transposition must be 4 columns wide by 6 rows deep.
    o If your transposed data block is to be offset from the origin of the new table, then you will need to include a subtractive offset into your cell formula, since in the transpose() function the data in the master data range is referenced from its position with the master range, not its cell position in the table. Such an offset is necessary because this example formula uses the target row and column numbers to arrive at indexed positions.
    For example, if the new data range is to be offset one column to the right and one row below from the target table's origin then you must subtract (-1) from the cell and from the column references in the formula:
      Example:
      =INDEX(TRANSPOSE(Table 3 :: $B$2:$D$4),ROW()-1,COLUMN()-1)
    If someone has a better solution I'd be glad to hear of it.

  • Keeping row and column headers while scrolling inside a Web Dynpro table

    Hi,
    I have to display a 2x2 matrix with storage location names on the x-axis (i.e. as Column Headers) and material names on the y-axis (i.e. row headers). The table data represents the quantities of a particular material in a particular storage location.
    I am using dynamic UI generation to create this table. It can contain as many as 150 columns and almost as many rows. I dont want a page level scrollbar, and hence, have placed my table inside a scroll container UI element with a fixed height and width.
    I need a way to let the users use the scrollbars inside the scroll container, but still let them see the row  and column headers. Is there a way that I can do this in Dynpro for Java?

  • Can we hide the tables and columns from subject areas in the front end

    Hi,
    Is there any way to hide the tables and columns from the subject area in front end.I need to create a report with some tables which the user does not want to see.So after creating the reprot can I hide those tables and columns in the front end

    Hi,
    Your question is not that clear to me...do you want to hide the entire table/column that dont want to show up in the front end then you could do in Presneation Layer in the RPD by going Permissions in the property of that object.
    But if you want to hide the column in the report that can be visible in the subject Area: go to column properties -> Column fomat...thereis Hide option.
    Can you please elaborate your question...what exactly you are looking for...

  • Make Select rows and columns as read only in Table Control

    Hi All,
    I would like to know how to make certain cells in a Table Control as display only.
    Table control should look like-(Those in bold are read only or in display mode)
    <b>Name1            Idno1 </b>         Address1
    <b>Name2            Idno2</b>          Address2
    <b>Name3            Idno3  </b>        Address3
    <b>Name4            Idno4</b>          Address4
    (Blank row to enter name idno and address)
    (Blank row to enter name idno and address)
    (Blank row to enter name idno and address)
    My table control should display all the above fields the way it is above of which first two colums and 4 rows should be read only,and the rest of the empty rows in the TC should be in change mode.i.e it must have provision to add new rows but not change the first two columns of existing rows.
    In short I am looking at solution to hide particular no of rows and columns and <b>not the entire column.</b>

    In the PBO of the table control loop. just write these statements
    NAME and IDNO considering the fields on the screen.
    and WA_TAB is the table work area being passed to the table control to display the rows.
    if not WA_TAB-NAME is initial and not WA_TAB-IDNO is initial.
    loop at screen.
    if screen-name = 'NAME' or
       screen-name = 'IDNO'.
    screen-input = <b>0</b>.
    modify screen.
    endif.
    endloop.
    endif.
    which means that the fields are disabled only if NAME and IDNO are not initial.

  • Sql query slowness due to rank and columns with null values:

        
    Sql query slowness due to rank and columns with null values:
    I have the following table in database with around 10 millions records:
    Declaration:
    create table PropertyOwners (
    [Key] int not null primary key,
    PropertyKey int not null,    
    BoughtDate DateTime,    
    OwnerKey int null,    
    GroupKey int null   
    go
    [Key] is primary key and combination of PropertyKey, BoughtDate, OwnerKey and GroupKey is unique.
    With the following index:
    CREATE NONCLUSTERED INDEX [IX_PropertyOwners] ON [dbo].[PropertyOwners]    
    [PropertyKey] ASC,   
    [BoughtDate] DESC,   
    [OwnerKey] DESC,   
    [GroupKey] DESC   
    go
    Description of the case:
    For single BoughtDate one property can belong to multiple owners or single group, for single record there can either be OwnerKey or GroupKey but not both so one of them will be null for each record. I am trying to retrieve the data from the table using
    following query for the OwnerKey. If there are same property rows for owners and group at the same time than the rows having OwnerKey with be preferred, that is why I am using "OwnerKey desc" in Rank function.
    declare @ownerKey int = 40000   
    select PropertyKey, BoughtDate, OwnerKey, GroupKey   
    from (    
    select PropertyKey, BoughtDate, OwnerKey, GroupKey,       
    RANK() over (partition by PropertyKey order by BoughtDate desc, OwnerKey desc, GroupKey desc) as [Rank]   
    from PropertyOwners   
    ) as result   
    where result.[Rank]=1 and result.[OwnerKey][email protected]
    It is taking 2-3 seconds to get the records which is too slow, similar time it is taking as I try to get the records using the GroupKey. But when I tried to get the records for the PropertyKey with the same query, it is executing in 10 milliseconds.
    May be the slowness is due to as OwnerKey/GroupKey in the table  can be null and sql server in unable to index it. I have also tried to use the Indexed view to pre ranked them but I can't use it in my query as Rank function is not supported in indexed
    view.
