Calculated columns?

Similar Questions

• ask a calculated column

  In a report, I used the source area to create a query that uses / creates calculated columns.
  Query:
  
  SELECT id, name, amount, percentage,.
  amount * percentage AS CalCost
  store
  where id = 3;
  
  Now, I want to create a calculated column in the query using the column "CalCost" created, similar to:
  
  SELECT id, name, amount, percentage,.
  amount * percentage AS CalCost.
  amount - CalCost AS difference,
  
  However, I get the error ORA-0094 indicating that 'CalCost' is an invalid identifier.
  
  Is it possible to calculate this column without raising this error?

  Yes - the alias is not available as of the SELECTION list. You will have to redo the calc, i.e.:

  SELECT id, name, amount, percentage,
         amount * percentage AS CalCost,
         amount - (amount * percentage) AS Difference
  FROM   store
  WHERE  id = 3;
  

  Alternatively, you can rewrite it as follows, where the alias expected to be available, but I see no reason to:

  SELECT id, name, amount, percentage, CalCost
         amount - CalCost AS Difference
  FROM   (SELECT id, name, amount, percentage,
                 amount * percentage AS CalCost,
                 amount - (amount * percentage) AS Difference,
          FROM   store
          WHERE  id = 3
         );

• Create a new calculated columns

  Hi all
  
  I want to create a calculated column with the following formula:
  
  Sales/Sum (Sales) * 100
  
  I got an error saying:
  ERRORS:
  [14041] error in the measure for the test of the column definition. Nested aggregate measure definitions are not currently supported.
  
  I can of course create in response but the user like a column or a shared measure (which may be reusable).
  
  Concerning

  In fact, you must create two columns in the business model.

  First, create a column of the measure based on the level for the denominator. It must be a measure of the year-level.

  Then, create the measure part as a separate column. Select 'Sales' in your business model, right click and select "Wizard of calculation" in the context menu. You can create an action that compares the year-level measurement.

• Aggregation in IR works incorrectly when using calculated columns breaks

  I have a problem with the aggregation in IR when using stops on calculated columns.

  Martin,

  I filed a bug about the problem you are having. The problem is when you control break on a calculated column with defined format mask and aggregates, the aggregate information is not displayed correctly. When I run the interactive report in debug mode, I see that analytical for aggregated information function partitions incorrectly. Using your example:

  IR runs this query to get the counts for each month of posting:

  count("AMOUNT") over (partition by "POSTING_DATE")
  

  Instead, it should run this query:

  count("AMOUNT") over (partition by to_char("POSTING_DATE",'RRRR/MM'))
  

  To work around the problem, you can change the calculation month without the format mask view and set to_char(F,'RRRR/MM'). Aggregates will display correctly.

  Hi user7417334,

  How did you define this measure? Did you do in the general tab (' logical use existing columns as source ")? If so, try to specify it instead on the Data Type tab.

  (1) uncheck "use logic existing columns...". »
  2) click the Data Type tab
  3) double-click your physical source
  (4) in the new box, make sure "Display unmapped columns" is checked
  5) click on the button next to your new column name
  (6) specify your formula here
  7) click OK until you return to the window of Data Type
  8) click the aggregation
  (9) set the SUM aggregation
  (10) save RPD and recheck your report.

  Best regards

• How to create a calculated column in another dimension

  Hi all

  I use OBIEE 11.9 on oracle 12 c.

  I have the following two dimensions in Bussiness model,

  

  I want to create FEMALES TOTAL logical column in dimension F1 student Graduation which is based on the column between the sexes in the student D1 dimension. The gender column has two possible values 'F', have '. the column TOTAL WOMEN should have sex for F.

  How I do that?

  Thank you.

  Kind regards.

  Add the dimension as a join table in the LTS made-> general tab, and then in the formula in the column, use a case statement to evaluate the dimensional condition and return the column done or 0.

  KEY: Size is not an LTS on its own by the way (as your picture shows)

  Oracle BI applications example:

  For staff than for those who is marked as active employees.

  

  Then the column DISTRIBUTION is: CASE WHEN 'Oracle Data Warehouse'. "'"' Catalogue'."" """dbo"."" "" "Dim_W_EMPLOYMENT_D '." " W_ASG_ACTIVE_INACTIVE_CODE' = 'A' AND ' Oracle Data Warehouse. "'"' Catalogue'."" """dbo"."" "" "Dim_W_EMPLOYMENT_D '." " W_WORKER_TYPE_CODE' = 'Worker EMPLOYEE' THEN ' Oracle Data Warehouse. "'"' Catalogue'."" """dbo"."" "" "Fact_W_WRKFC_EVT_MONTH_F_Snapshot '." " END OF MEMBERSHIP"0 OTHERWISE

• APEX 4.2.5: Calculated column, how to?

  Good afternoon

  I've followed columns in a table:

  last_name

  complete_name

  The complete_name column should be filled in as: last_name + "," + name »»

  Example:

  name = James

  last_Name = Bond

  complete_name = Bond, James

  
  

  The complete_name column is used as a unique key.

  What is the best practice to achieve this?

• calculated column

  Hi gurus,
  
  I wanted to create a logical column in fact table for 2 products-prod1 and prod2 = sum of values
  How do I do that
  
  Thanks in advance
  Collery

  The way you have created 'Prod1 sales value' create 'Prod2 sales value '.

  Now, create a derived column "Part of Prod1" and in the formula give

  fact_table. "Prod1 sales value '/(fact_table.) '. ("" Prod1 sales value "+ 'Prod2 sales value')

  And in the responses, create a tabular report with columns

  Calendar_Day, "Prod1 sales value", "Value of sales Prod2", "Prod1 share"

  And check the results...

  hope its helpful...

  Thank you

• Columns of the rendered suddenly do not report in Prod.

  I have a report that worked fine until 1 week ago. The report has not changed in 2 years. Some columns do not have to return (appear hidden) that should appear and values appear in the wrong column (transposed). All other reports are worked as expected. What is particularly strange is that reports works perfectly in dev. I moved it back and forth between Dev and Prod several times to verify that it works in Dev but not in Prod. All other reports of work in both environments. I'm on 11.1.2.3 and recently had no change in my environment.

  Any ideas on how I could fix this, other than to rebuild the relationship?

  Thank you

  FA

  I discovered the problem. The column out of which all other calculated columns has been marked to always hide. However, a more thorough investigation, I learned that she was also conditional deletion. It's bad design in 2 ways, since it was already hidden had no reason to delete, but it value also suppressed = 0, which then caused the error. It was the first time, that all values equal zero if the error was not known until today.

  Add a POWER_PREVIOUS column to your report query using the analytical function LAG to access the value of the POWER of the previous row. Use the ORDER byclause in the function to determine the order of the lines. The calculation of the IR then simply uses the POWER and POWER_PREVIOUS values for the same line.
