• Select the last value for each day of the table

  Hello!
  
  I have a table that contains several measures for each day. I need two queries on this table, and I'm not sure how to write them.
  
  The table stores the rows (sample data)
  

  *DateCol1                 Value       Database*
  27.09.2009 12:00:00       100           DB1
  27.09.2009 20:00:00       150           DB1
  27.09.2009 12:00:00       1000          DB2
  27.09.2009 20:00:00       1100          DB2
  28.09.2009 12:00:00       200           DB1
  28.09.2009 20:00:00       220           DB1
  28.09.2009 12:00:00       1500          DB2
  28.09.2009 20:00:00       2000          DB2

  Explanation of the data in the sample table:
  We measure the size of the data files belonging to each database to one or more times a day. The value column indicates the size of the files of database for each database at some point (date in DateCol1 European model).
  
  
  What I need:
  Query 1:
  The query must return to the last action for each day and the database. Like this:

  *DateCol1       Value      Database*
  27.09.2009        150          DB1
  27.09.2009       1100          DB2
  28.09.2009        220          DB1
  28.09.2009       2000          DB2

  Query 2:
  The query should return the average measurement for each day and the database. Like this:

  *DateCol1       Value      Database*
  27.09.2009       125          DB1
  27.09.2009      1050          DB2
  28.09.2009       210          DB1
  28.09.2009      1750          DB2

  Could someone please help me to write these two queries?
  
  Please let me know if you need further information.

• Drag and drop the element of the array of Clusters

  I have a project that includes an array of 'tests', each of which is a cluster that contains an array of 'numbers', a matching the regular expression string and an array of "tasks" (all of them, is in turn, a group of elements).

  It is:

  • Tests (table of):
  • • Cluster:
    • • Reference numbers (an array of strings)
      • Regex (string)
      • Tasks (table of):
      • • Cluster:
        • • Task type
          • Basic channel,
          • Measuring channel
          • Other channels

  I wish I could drag and drop to rearrange the task table in an individual event.  (It is a nice-to-have rather than a urgent request - more for my own learning that no matter what).  For now, I've implemented "Move up" and "Move down" buttons

  Examples are fine for a single cluster that includes a table or an array of objects.  As soon as we have an array of clusters, it is difficult to access individual items within a specific cluster.

  Who that it be completed can drag and drop into such a facility?

  Curiously,.

  Geoff

  Hello GeoffF,

  It's certainly doable and you can even use the standard start drag and drop methods/events, the trickiest part is to determine the table of the elements that are selected on the mouse towards the top/mouse downwards and the swap of manual handling.  Fortunately, there are a few decent examples of how do this out there already, I suggest you take a look at this one:

  Example of community: determine the Index of the clicked element Array in LabVIEW

  https://decibel.NI.com/content/docs/doc-22434

  That should give you the selected table indexes, and then all you have to do is to move the elements around around the drop event.  I have attached a very basic demonstrative example that uses this code I just linked (you need to download that as well) and the events referred to swap two elements of the array.   The attached code is just thrown together, you'll want to design something more robust and scalable to any sort of actual use.

  Kind regards

• Default value for the select list of type of form elements

  Hello
  
  I do not work with Apex that mutch, so this may be a simple question... but I still need help.
  I have a form, in this form, I have a question P19_ONTVANGER_ID, this is based on a LOV.
  This LOV is on a table that has a field of username with the value of APP_USER.
  The table looks like:
  ONTVANGER_ID this is the PK and is going to be the return value from the LOV.
  NAME is the display value for the LOV.
  USERID is the column APP_USER.
  
  What users would like to get is that if they create a new record, the default value for the P19_ONTVANGER_ID field is their own ONTVANGER_ID.
  But they must also be able to select another user.
  
  hope there is someone out there that can and will help me.
  
  Kind regards

  You can select the Type of default value as the body of the PL/SQL function

  and to add something like that

  declare
  v_return number;
  begin
    select your_id
      into v_return
    from your_table
    where some_column = :APP_USER;
   return v_return;

• function to set a default value for a column that is defined by the user

  Hi all
  
  Can use us the user-defined function to set a default value for a column?

• Type/conditional default value for a form element

  Hello
  
  I have an interactive report with a form on the table 'A' who 'Who' has columns like 'CREATED_BY', 'LAST_UPDATED_BY '. Now, I'm auto these columns in the form with the & APP_USER. function. The scenario occurs when the 'P' user clicks on the button 'CREATE' on the report, these columns of the report get populated info P. After committing this recording, the "Q" user edit this record even with the link 'Edit' in this folder. The two columns get populated by the Q news, ideally only LAST_UPDATED_BY should get populaed by the news of the Q and not the CREATED_BY column, as it is the 'P', which created this record.
  
  To do this, I guess that in the type of default value for these items, I have to use "Body of the PL/SQL function" instead of "static text with Session of Substitutions in State". Problem is to know how to code the filter: If the user pressed 'create' button or the button "Edit". Help, please
  
  Thank you
  Mary

  Hi Mary

  Usually, I would do this sort of thing on a trigger. However, you could do the conditional CREATED_BY field on the primary key of the record is null (which is itself a new record, but it must have a value of an existing record). The LAST_UPDATED_BY field should not be conditional, as it should be the name of the user who recorded the record.

• call a stored procedure for each row in the transitional attribute and display the data in the form of af: table. The other rows are based on the entities

  Hi Experts,

  I need to call a stored procedure for each row in the transitional attribute and display the data in the form of af: table. As well as other attributes.

  I think that you need a stored function (which returns the value) in this case, is not?

  Take a look at:

• The default value for a property with data of type boolean

  Hi all

  Is it a system preference setting, where the default value for a property with data of type boolean can be a Virgin? I want to keep the value by default in a vacuum, but every time I save the property even after empty selection, the default value changes to FALSE.

  

  In this case Boolean doesn't help you, you mayneed to create a chain of ownership and have true/false / "" as your list of values

  Specifically, the two simple solutions provided were:

  1 using the row_number, entitled Oracle ranking based on descending order of the inside telephone each empnum group. And finally selects the lines which has least rank (of least since that order is descending for phone).

  SQL > column alternatecontact format A20;

  SQL >

  SQL > SELECT empnum, alternatecontact, relationship, phtype, phone

  2 from (SELECT a.*, row_number() over r (PARTITION BY empnum ORDER BY phone / / DESC))

  3 FROM xxc_contact one)

  4. WHEN r = 1

  /

  EMPNUM ALTERNATECONTACT RELATIONSHIP PHTYPE PHONE

  2. with the help of MAX, Oracle automatically assigns the maximum phone for all the rows in each group of empnum. And finally selects the rows with the maximum phone. Order by clause is omitted here intentionally. You can find out why.

  SQL > SELECT empnum, alternatecontact, relationship, phtype, phone

  2 (SELECT a.*, MAX (phone) over (PARTITION BY empnum) rn FROM xxc_contact one)

  3 WHERE phone = rn

  4.
