Functions using nested

• Functions of nested groups

  I thought that max (count ()) must be performed on separate groups of rows returned from GROUP BY deptno.
  However, it seems that count() is performed according to GROUP BY while max() is performed on the result of count()... GROUP BY.

  select max(count(deptno)) from emp group by deptno;

  Why is this? How does the nested group functions operate against the GROUP BY?

  Why is this? How does the nested group functions operate against the GROUP BY?

  Well, look at the statement. There is nothing more than a "condensed" to form:

  select max(cnt) from (select count(deptno) cnt from emp group by deptno)
  

  Everything said is calculate number in each group deptno and then calculate max of counties. Another word, what you call "nested" grouping always returns a single line. GROUP BY clause, if any, still applies to the internal group. External pool always implicitly uses GROUP BY and therefore query always returns a line even when the internal grouping produces no line. Grouping in same way THAT HAVING applies inside. In fact, you cannot specify HAVING for the external group:

  SQL> select max(sal) from emp group by deptno;
  
    MAX(SAL)
  ----------
        2850
        3000
        5000

• Easy way to locate the function used on the diagram by name?

  Is there an easy way to locate the functions used in the diagram under the name of the generic function?

  I have user appears somewhat to the user on my diagram functions to help me debug a difficult sequence of agross events live multiple now that it works, I want to go back and disable most of these postings. Most of them went up to now within the layers a little structure and is not easy to find.

  So is there an easy way to get a list of where these functions are used so that I can quickly go and edit them?

  I find the function is with the display hierarchy that does just what I need.

  Thank you.

• Can I call a function using the array index?

  I defined a table that stores the name of the function, like this:

  var aresetButtonTop:Array = new Array(resetTop1,resetTop2,resetTop3,resetTop4,resetTop5);

  Then I have a button named "btnresetTop" which, once clicked will be called one of the five functions stored in the array (aresetButtonTop) above. Functions are called at runtime depending on certain conditions. I need to figure out how I can call these functions using the array index. I use the following code to call the function. The value of i has already been calculated.

  
  

  btnresetTop.addEventListener (MouseEvent.CLICK, aresetButtonTop [i]);

  After doing this, I get the following error when I click on the button:

  TypeError: Error #2007: parameter listener must be non-null.
  at flash.events::EventDispatcher/addEventListener()
  at gallerytest_fla::MainTimeline/thumbTopClick()

  Note: thumbTopClick() is a function within which all these codes are written.

  I need to know if it is posible in AS3 to call a function name using array index or not. If so, could you afford ehelp me out.

  You can certainly do.

  In your case, it looks like i is out of range. Show your loop.

• Can a DB function used between 2 pools of connections

  Hi all
  We have 2 pools of connections, 1 connected to Oracle DB Data Warehouse. The other connection pool is an Excel spreadsheet, which has projects and scheduling dates. We have modelled in MDB and her servant perfectly. Now, the question is, we have a function in Oracle DB, which works well when I use with any size of Oracle DB DW. But, when I use the same function using the dimension modeled of excel sheet it generates an error. Here, dimension sheet Excel is modeled to inculde model DW.
  
  Error: "A general error has occurred. [nQSError: 42015] Cannot function ship the following expression. »
  
  So my question is "is there no work around to use the same function when using the other connection pool size.
  
  Pointers for this problem is highly appreciated.
  
  Thank you
  Vijay

  Hi Vijay,

  I agree 100% with what Dave. The function you have in Oracle should have access to the values passed in. OBIEE has access to both DIM_DW and DIM_EXCEL, but the Oracle function has no access to DIM_EXCEL. Just to give you a high level understanding of what is happen, here's what OBIEE made to combine the two sets of data in a single report:

  Assume that your report is like so: DIM_DW. COLUMN1, DIM_EXCEL. COLUMN2, FACT_DW. MEASURE1

  To get the data OBIEE sends two separate applications: one against the DW that retrieves DIM_DW. Column1 and FACT_DW. MEASURE1 and another for DIM_EXCEL. COLUMN2.

  Once the two request to return, the OBIEE server joined data sets and then presents them in a report.

  Now, when you call your function (DIM_DW. COLUMN1, DIM_EXCEL. COLUMN2), OBIEE sends the request to just the Oracle DB. But the Oracle DB can not see the Excel data, then it fails because the DIM_EXCEL argument. Column2 is not defined to Oracle DB.

  Here are two methods you could use to make it work:
  (1) configure the Excel file as an external table in the Oracle DB. Then, the function would be aware of the values of column in Excel.
  (2) port the function to the MDB using layer logic the formula Expression. According to what is your function, it is not possible.

  Whatever it is, how you install now, you can't reach your goal. The reason why I recommended that you separate your connection pool Excel in a different database object is because the way you have it setup right now makes it appear like the Oracle DB would be aware of the Excel tables. But that's not true. Keeping them separated to avoid any future confusion.

  Good luck!

• How can I create a function using variables TestStand and call from Meadow step Expression?

  In one sequence, I have dozens of prior Expressions, which are almost the same thing, like this...

  Locals.tagID = (Parameters.singlePhaseEnabled? ('L': "D") & Str (Locals.phase) & "006".

  .. and the only thing different is this three-digit string in the end ("006" may vary). How can I write a function that I can call from Meadow step Expression then it should look like this? ...

  Locals.tagID = MyNewFunction("006")

  You can not write custom expressions for commands.

  That being said, there are two options:

  • Create a sous-suite with a single step. Use a setting of the sequence as "function parameter.
  
  
  • Create a step type custom including a lower level module that implements the function. Add a step edit to allow the user to the steptype graciously change the setting.
  
  
  • Store the variable setting in a local global variable / file and change the value in each step. This will, at least, keep the same 'function' for each step.

• using nest if then statements using ABM

  I have a two input, 1 output circuit, as in the attached schema. My third node is set down by the very high resistance voltmeter. What I have is a user defined current source ABM that depends on other parameters in the circuit. I wonder it is what my conditional statement is entered in the right format? Conditions are particularly complex and describe as follows:

  If the voltage difference between V2 and U1 is greater than 0, then the current in the ABM = 10 ^-12

  If this voltage difference that the above is not greater than zero and if (V (1) u (1))<(V(2)-U(1)), then="" the="" abm="" current="" is="">

  Otherwise, if (V (1) u (1)) > = (V (2) u (1)) then the current is (0.1*((-(V(2)-U(1)))^0.35))*0.00001596*(((V(2)-U(1))^2)/2)

  As you can see, they are very complex conditions and my concern is that I can't just type in U1 and get the compiler to understand I want the voltage read on the voltmeter of bottom-node. I think I'm using the correct nesting in the encoding format is: if (T, X, (if(Q,R,S))).

  Any help would be appreciated, and details can be provided.

  I don't know why its not throwing an error for the use of u (1), maybe it's a valid keyword.

  If you want to reference a voltage properly, it should be V (net_name) for single ended voltages (referenced to ground) or V (net1, net2) for differential voltages... For models ABM I suggest turning on net visibility throughout the schematic so that you know the net name to the positive terminal of U1 or anywhere else for that matter.

  I think the syntax you have to if/then/else is correct otherwise.

• How s/n know when and what account perform a function using the database link?

  Dear,

  My application of the CIM team asked DBA to create new function and run it. Function must use the database link for remote database data. So I need to create a new database to their licensing link. Cause we guess we'll experience the performance issue after the user performs this function, or another question and errors may occur. So we want to know when and who use this feature that connects to a remote database through the new database connection in advance. And I also need to know when and which connect to the remote database using this new database link. We have no idea to get this information?  Can anyone recommend how do? Thank you very much.

  Best reqards, Otis.

  Check what business purpose, it will solve.  If the function is so safe, why everyone will use. Only admin people should access.

  All of these additional controls of this kind must be avoided as much as possible to improve the overall performance of the application.

  Still if you need, see the database audit mechanism, specifically designed for this type of activity.

  Kind regards

• Create/edit functionality using popup

  Hello

  I do face-down question on one Page ADF:

  I have read only the ADF. Under the table, there are 3 buttons (Edit current line, create new & Commit).
  The two edit/create button opens a popup window showing the ADF form for the selected line in the case of edit and new blank line while creating new. From there I can make changes, and then use save or cancel button to return to the home page. The table of automatically refreshes with the new changes if I press the button Save on popup. If I press the Cancel button, there is no change in the table on the home page. The edit functionality works very well.

  However, if is created, the table shows newly created line even if I click on Cancel button on the pop-up window. The table should show the new line only if I select Save button on the pop-up window.

  I use 2 BTF for this. (Control data)
  BTF 1:
  MainPG (edit)-> EditBTF
  MainPG (create)-> createInsert()-> EditBTF

  2ND BTF:
  EditPG (Economics)-> back
  EditPG (cancel)-> back (restore save point = TRUE)

  Sushant-

  Why the question comes only in the case of create new ones?

  Because when you cancel popup, the values are not subject, but when you create new rank (CreateInsert) this is automatically applied.

  Also, the second part of your post, I noticed that you use BTF to add/change features in order to check these links:

  What do you mean by "transform Oracle?

  If you are referring to the integrated database XSLT processor available through XMLTransform or DBMS_XSLProcessor API, it does not support XSLT 2.0, 1.0 only.

  If you use the XDK Java (oracle.xml.parser.v2) Please give the exact version.

• Why the hell use nested tables?

  Hello
  I'm boning up on top of the PL/SQL (again) waiting to get a new job.
  I have several years of experience in various roles related to the data, including many used Oracle.
  On the issue of collections, I ask myself, in light of my experience, to find and not for the first time, why the hell would anyone want to do this:
  
  

  create or replace type TEST_TT as table of varchar2(10);
  /
  
  create table TEST_TABLE ( X number
                           ,Y test_tt) 
                           nested table Y store as Y_TABLE;                      

  I really, really, can't think why we want to store data like that. It seems unnecessarily complex, hiding a one-to-many relationship inside TEST_TABLE, which should rather be modeled and implemented as a separate table.
  In addition, there are a lot of tutorials on the collections that tell us how to do the above (in fact I read Feuerstein right now), but nobody seems to tell us WHY we should do it.
  
  Can someone help me out here?
  
  Thank you.
  Jason

  I can't imagine wanting to create a table like this one either (or, if this can help, can Tom Kyte).

  The collections are terribly useful in PL/SQL, when they help you avoid one treatment per line. I can't imagine wanting to integrate into my data model. Frankly, it's much the same with the types of objects - they are quite useful in PL/SQL, but I would never want to create a table in my data model that contained an object.
