Display two columns of the sum

Hi all

I am a beginner and need help on a requirement.

I have a table.

Level of ID data
----------------------
1 TL 200
1 BT 200
1 TL 200
1 BT 300
2 TL 300
BT 2 400

I want to display:

ID Sum (BT) Sum (TL)
----------------------------------
1 500 400
2 400 300

Thank you very much.

You have to change the table and column names.
The column names that you use are reserved words of Oracle...

select pk
,      sum(case
             when lvl = 'BT'
             then descr
             else 0
          end
          )sumBT
,      sum(case
             when lvl = 'TL'
             then descr
             else 0
          end
          )sumTL
from   t
group by pk;

Output:

        PK      SUMBT      SUMTL
---------- ---------- ----------
         1        500        400
         2        400        300

    Anyone know how I can create a ViewCriteria where clause that compares the two columns of the same table?

    For example if I had two columns of integers (MINSAL and MAXSAL) and wanted to see if they are equal. Normally, I would do the following SQL below.

    SELECT * EMPL
    WHERE MINSAL = MAXSAL

  • Need to display more than two columns in the game now (library view)

    The current reading list (under the library, not the instant game tab menu tab a top of the player) shows only two columns, the title and duration.  I can't add more columns by selecting choose columns, or restore the columns.  I have this problem with one of the entries in the left column of the display of the library (like, songs, recently added, etc.).  Is there a way can I fix?

    It's machine running a version of Windows XP on the computer and WMP11.  I had Windows XP and media player 11 on my laptop for several years and have had this problem.  I don't know what is different between the two machines that causes this problem.

    Yes, it seems to be more at hand than just differences in operating system. However, I think I found a way to get more columns in the game now:

    1 restart WMP, start to play music and go to playback.

    2. click on the heading of column Title to sort by title.

    3. switch to another view (for example songs ) and go back to playing now. You should already see the additional columns now.

    4. to make the columns 'stick' between reboots WMP, you also needed to right click on the column header in the current playback, select Choose columns , uncheck automatically hide columns and click OK .

    b include these columns in the GROUP BY clause and not to use the SUM,
    (b) the GROUP BY on rec_a alone, separately, can't join the results to the rec_b, or

    SELECT    B.key_code

    I hope that answers your question.
    If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the results desired from these data.
    Point where the above query is to produce erroneous results, and explain, using specific examples, how you get the right results from data provided in these places.
    Always say what version of Oracle you are using (for example, 11.2.0.2.0).

  • Calculation on two columns in the pivot table

    Hi all

    I have a vision:
    Dept. year amount
    Accounting 500 $2010
    Accounting 700 $2011
    $100 engineering 2010
    $600 engineering 2011
    and etc.


    PivotTable: (data displayed side by side)

    Dept: 2010 2011
    Accounting 500 $700 $
    Engineering 100-$600

    Is there a way of PivotTable to create the additional column, and do the math on this column? New column called 'Change' (amount of real computation of 2010 less amount of 2011 by each Department). I see the function to duplicate columns in the PivotTable. But that's it... without additional calculations.

    Thank you in advance,

    Sonya

    Pretty easy simple n...

    Your year must be in the columns area... Simply create a new collar calculated say diff with function as formula and formula of the sale as a "2011" "- 2010". This will give you the sum of diff. You can do this more flexible by making use of $1 & $2 to reference...

  • display / hide column of the table running

    Are there known issues with display / hide a column of the table at run time?

    I have a table that contains a column with a check box and another with a radio button.  If the user is allowed to select more than one row in the table (as indicated by a form variable), then I want to hide the column of radio and checkbox column.  If not, I want to show / hide the contrary.

    I show / hide the column header too.  When I preview the form, however, the data in the table appears "scoot" left and placed in the column that is hidden, so to speak.

    Here is a view of the design of the table:

    tableDesignView.jpg

    And a view of the execution of the table.  You can see the radio is hidden, but the "account number" column wants to crush in the (hidden) radio column,

    tableRunTimeView.jpg

    Here is the script, I'm very confident in this small snippet of code because the lines of account were filling wonderfully until I added the column of radio buttons and the script to show/hide.

    Put the account data in the table

    function

    setAccountData (objAccountRow, objAccountItem) //Pass in the line and data to complete line

    {

    stuff the line

    objAccountRow.accountNumber.rawValue

    = objAccountItem.accountNumber;

    objAccountRow.accountName.rawValue

    = objAccountItem.accountName;

    objAccountRow.accountBalance.rawValue

    = objAccountItem.accountBalance;

    display the check box or radio button, depending on the number of accounts they are allowed to select (as specified by the form variable)

    var searchNumAccounts = objFragment.resolveNode("searchNumAccounts").value; Variable //Form

        if (searchNumAccounts==1)

    { //show the column of radio buttons and hide the checkbox column }

    hideObject (objResultsSubform.accounts.HeaderRow.txtSelect);   <-it's exaggerated here, to hide the table for each row header column,...

    hideObject (objAccountRow.accountSelected);

    showObject (objResultsSubform.accounts.HeaderRow.txtRadioSelect);

    showObject (objAccountRow.radioSubform.radioGroup.selected);

    }

    on the other

    { //show the checkbox column and hide the column of radio }

    hideObject (objResultsSubform.accounts.HeaderRow.txtRadioSelect);

    hideObject (objAccountRow.radioSubform.radioGroup.selected);

    showObject (objResultsSubform.accounts.HeaderRow.txtSelect);

    showObject (objAccountRow.accountSelected);

    }

    }

    OK I got it. The table object implements a container to contain the fields. You hid the ok fields, but you then never reset the row in the table to have only two columns. I copied the parameter of the XML source so that I would have the exact width and then deleted the one I wanted to hide. Now everything works fine.

    See the example updated the.

  • How to update a record, if it is a composite key (primary key is based on two columns) in the OPS? page?

    Hello

    Actually I got to know this update of a record must be made when the primary key is based on two columns.

    Previously, I used SPEL for a column. It was working fine.

    But I came to know that regardless of the folder I try to update, it was the update page is coming up with the first combination of the record.

    As if RC 131

    RC 124

    RC 125 are the records.

    If I click on update of RC 124 also, the update page is coming up with RC 131 values as it is the first.

    So I understand that the SPEL should be based on two parameters, because it is a composite key.

    How to do?

    Please let me know if you don't understand the problem.

    Thank you.

    Hello

    The script below produces what you want (as far as I can tell, without your desired results).

    Student_score_smry subquery Gets the year and monthly averages of student_score.
    It is completely static: it always produces 11 monthly columns (from January to November) and the names of columns hardcoded (m01 through m11).
    For dynamic column names you need, I used SQL * COLUMN more orders.
    To get the variable number of monthly columns you need, SELECT from the main query clause uses a script under (dynamic_month.sql) to only show the correct number (which can be 0).

    The student_score_wk_smry of subquery retrieves the weekly averages of the student_score_wk.
    He, too, is completely static: it always produces 6 weekly columns with names hardcoded (w1 through w6).

    There are four preliminary motions, that write two scripts under:
    Prelimiary C1, C2 and C3 queries write orders of COLUMN for annual, monthly and weekly columns in dynamic_columns.sql
    Preliminary motion M written between 0 and 11 items in SELECT-clause in sub-script dynamic_month.sql

    The main script is:
