• Hard analysis of the same statement

  Simple example:

  SQL > select * from table_1 where col_1 =: b;  -can also use literal here

  Use "INDEX RANGE SCAN.

  SQL > alter session set OPTIMIZER_INDEX_COST_ADJ = 1000;

  Will cause the same instruction to use "TABLE ACCESS FULL".

  
  Why the database generates new plan? When the same statement is still hard analyzed, assuming there is enough space in the shared pool and the statement is not 'Compatible with Bind?

  Thank you.

  The view V$ SQL_SHARED_CURSOR shows some of the causes as to why the optimizer will choose not not to share an existing child cursor.

  Change OPTIMIZER_INDEX_COST_ADJ falls under the cover of OPTIMIZER_MISMATCH.

  The question that arises is almost reversed from what you ask.

  It is not so when the optimizer chooses to make a difficult analysis.

  It's more when a cursor existing being/not reusable.

  that is, you will get an analysis hard whenever there is no such thing as an existing child shareable cursor.

  So, if you run the SQL statement in a session and lend an existing child cursor reuse does not exist, then you will get a difficult analysis.

• How to maintain the same State of the application after closure and reopen the app?

  Hello

  My problem is while accessing the request, if I close and reopen the application then the previous state of the application is at a loss.  Please help me to maintian the same State of the application after close and reopen the app means reopen after application, enforcement should be focused on the last viewed item and I used the browser component if I reopen the app, then content browser also be there under the previous state.

  Advanced thanks for any help.

  One proposed by Simon is 'Close' and that you save enough information to rebuild your Application in the State was restoring it when it is reopened.

  Alternately, instead of really close your application, you could just put it on the bottom using

  UiApplication.getUiApplication () .requestbackground ();

  Once in the background, when the user selects again your application it will start immediately and will be exactly as it was left.

  This does not, of course, runs through judgment or commissioning of treatment you could want, so, for example, will not store all resources you want to put away when you know that the user is going to use your app for a while.  To help with this, look at the Application.activate () and Application.deactivate () methods.

  I hope this helps.

  This is a query that reads and writes the same data on the same partition!

  I think that it is generated by Oracle, but I don't undestand what he does.

  Can you give me some explanation or assistance on this query?

  Thank you very much

  This is a query that reads and writes the same data on the same partition!

  Well not - enough is NOT that.

  The RELATIONAL indicator causes unnest Oracle object data and insert the data from the attribute itself rather than the object.

  The indicators used are usable only by Oracle-c ' is why they are undocumented. You can find songs on the web, but practically everything you find is "best estimate".

• dynamically generate multiple instances of the same subform

  I have the field box where the user can select up to 10 accounts.  For each account, I need to have a certain display subform.  So if the user selects 5 accounts need 5 occurrences of the same subform.

  Is it possible by programming?  Or do I have to have 10 subforms and just hide/show what I need?  I prefer the former, if can be done.

  Please advise,

  Thank you

  Elaine

  Of course, it is not too hard once you know what you're doing.  First of all, make sure that all subforms of 'parent' of your subform are defined to be "Flowed" in the object tab, and that your subform is set to "repeat subform for each data element" in the binding tab.  For example, your user enters the number of accounts they have in a numeric field or text (we'll call it Number_of_Accounts).  At this point, you might have the form to generate the number of instances of the subform you want when the user leaves this area, or you could have a button that says something like "generate accounts."  Whatever it is, your script will be something like this:

  _Accounts_Subform.Count = Number_of_Accounts.rawValue;

  This will generate the number of instances of the requested subform.  A warning-if the person changes the value of Number_of_Accounts after they put a (i.e. in a first step, they said 5 but then it changed to 3), the instances at the end to go (so in our example the 4th and 5th instances would be deleted).  I suggest putting a warning in the same place, you put the script above, so it will look like

  If (_Accounts_Subform.count > Number_of_Accounts.rawValue) {}

  If (xfa.host.messageBox ("attention! You are about to permanently delete all accounts after the number"+ Number_of_Accounts.rawValue +".. "  Are you sure you want to continue? ', ' danger! "(, 3, 2) (= 4) {}".

  _Accounts_Subform.Count = Number_of_Accounts.rawValue;

  }

  else {}

  Number_of_Accounts.RawValue = _Accounts_Subform.count

  }
  }

  else {}

  _Accounts_Subform.Count = Number_of_Accounts.rawValue;

  }

  In addition, I suggest putting a delete button with each instance of the subform, so they can remove a case at a time and specifically (i.e. delete the first instance without deleting all subsequent instances).  A start-up caution-make sure that your "addresses" are correct (in this case Accounts_Subform and Number_of_Accounts).  If you are not sure if an address is correct, select the object on which you are scripting, go in the script editor, hold down Ctrl, and click in Design view, on the object you are trying to reference.  I'm sorry if this is not clear, but I can't imagine a better way to explain this right now.

• different results for the same statement 9i / 10g why?

• How to select data using the same remote database column name 3

  Hello
  
  
  Can anyone help me on how to get the data with the same remote database column names 3 and a unique nickname.
  
  E.g.
  
  SELECT *.

  Of

  Not valid. This makes no sense and breaks all the rules of scope-resolution. And if it is in a single database, or uses tables in databases, is not relevant.

  Each object must be particularly well identified. If you cannot do this:

  select * from (table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3) a
  

  3 objects cannot share the same alias. Example:

  SQL> select * from (dual, dual) d;
  select * from (dual, dual) d
                     *
  ERROR at line 1:
  ORA-00907: missing right parenthesis
  

  You need to combine objects - by using a join union or similar. He will have to be done as follows:

  SQL> select * from (select * from dual d1, dual d2) d;
  select * from (select * from dual d1, dual d2) d
         *
  ERROR at line 1:
  ORA-00918: column ambiguously defined
  

  However, we need to have unique column in a projection of SQL names - so the join of the need to project a unique set of columns. So:

  SQL> select * from (select d1.dummy as dummy1, d2.dummy as dummy2 from dual d1, dual d2) d;
  
  DUM DUM
  --- ---
  X   X
  
  SQL> 
  

  I suggest that you look carefully at what opportunities are and how it applies in SQL - and ignore if the referenced objects are local or remote, because it has no effect on the basic principles of scope-resolution.

• Not all the same States menu

  On the Organization , there is a menu for 'organization '.

  I still for the button States, the text itself has no distinct States, so it will not interfere with each other.

• Two tasks that share the same resource in sequence

  I'm the current exception "the specified resource is reserved.". I understand that you can not run two tasks that share the same resource at the same time. However, is it true that you can not run two tasks that share the same resource, one right after the other, without the eliminate completely from the first task?

  for example

  Task1 and task2 share the same resource
  
  Task1. Start();
  
  Task1. Stop();
  
  Task2. Start(); This will always throw an exception until you have a task1 (i.e. task1.) Dispose()?
  
  Task2. Stop();

  Hi cafarm,

  You're right, the fact to just stop at one task does not allow that run you another task with the same resources immediately after. That being said, you can start the next task without having to erase or dispose of the first by making use of the task status template DAQmx. As you can see on the next page, stop a task simply going to the State of "Clerks", which means that the material is still used by the task even if she does not actively.

  http://zone.NI.com/reference/en-XX/help/370466AC-01/mxcncpts/taskstatemodel/

  Instead, you can use the control functionality of task for the first task of transition to the status "verified" after stopping it, then start the second task. This keeps the parameters of the task without having to have the task, but it should free up resources to be used by other tasks.

• generate a diff xmlelements at the same level

  How can you generate different xmlelements at the same level. for example as follows:
  

  <APPLICATION NAME="test" DATE="30-NOV-12">
    <ELEMENT1>
       <ELEMENT1_ATTRIBUTE1>
    </ELEMENT1>
    <ELEMENT2>
       <ELEMENT2_ATTRIBUTE1>
    </ELEMENT2>
  
  </APPLICATION>

  item 1 and item 2 are at the same level.
  
  I tried to generate, but have failed so far.
  I want to extract data from table 1 element1, item 2 data from another table, both tables are not related.

  Hello

  You can nest 2 XMLELEMENTs inside an another XMLELEMENT, like this:

  SELECT XMLSERIALIZE ( DOCUMENT     -- for display only
       XMLELEMENT
       ( "APPLICATION"
       , XMLATTRIBUTES ( 'test' AS "NAME" )
       , XMLELEMENT
         ( "ELEMENT1"
         , d.dummy

  CROSS JOIN  user_users  u
  ;
  

  Output:

  TXT

    FUBAR
  
  

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.
  Explain, using specific examples, how you get these results from these data.
  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

• several objects have the same rollover both State (but the link to different pages)

  Hello

  I have a mac

  I would like to know how I can get several images with the same States of reversal - but who appear both on several images, (but each element having its own binding property applied to this)?

  See image below: I want the two box 'A' of pop with the same State of turning even if I'm hovering on one of the boxes. But I want that each of the boxes to post a link to different pages of my site.

  Ive tried to group the images and moving them to their own layer, but the bearings are not "and" associate on several objects

  Help!

  Thank you

  

  It is not, but you don't need that to get the behavior you described. A1, a trigger will States and the hyperlink you want. On rolling, it will show its rollover State and show its target container that will be directly on top of A2. It will look like a rollover for A2 State. Repeat for A2, B1 and B2 and I think get you the behavior you described. It is simply a different way of approaching the problem (what happens to adapt the tools available in Muse).

• Prevent the same selection in the menu in a Table expanding

  Hi all

  I have a table 2 x 2 in which the top line is a header line and the line of the low 'Row1 '. Row1 Cell1 has two buttons, one to add a new Row1 using Javascript click script of the instance:

  this.parent.parent.instanceManager.addInstance)

  .. .and one for delete all Row1 using Javascript click script of the instance:

  rowNum var = this.parent.parent.index;

  this.parent.parent.instanceManager.removeInstance (rowNum);

  Row1 Cell2 contains a datadropdown object.  Basically, when a user adds an extra Row1, I need prevent the to select a previously selected item in the list of dropdowndata.  I can't understand because I'm trying to set up output instance script (or would be - this script validate?) who's trying to reference Row1 [*].  In most simple situations where I have two fixed objects, I just made this as an output FormCalc script:

  If (Object1 = Object2)

  then xfa.host.messageBox ("you cannot select the same thing again")

  and xfa.host.resetData ("Object1")

  endif

  ... that prevents the user to select something with the same rawvalue by alerting the, then turning off the field.

  I hope this makes sense and someone can help!  Thanks in advance for all the gurus of adobe there

  Hello

  Would it not possible to filter the choices in the drop-down list that have already been selected.  If so, you could try something like this JavaScript in the event your falling down preOpen.

  dropDownItems var is ['abc', 'def', 'hij'];.

  var lines = Table1.resolveNodes ("Row1 [*]");

  for (var i = 0; i)< rows.length;="">

  {

  var line = rows.item (i);

  If (! line.) DropDownList1.isNull)

  {

  dropDownItems = dropDownItems.filter (function (item) {element return! == row.}) DropDownList1.rawValue});

  }

  }

  this.setItems (dropDownItems.join(","));

  The first line Initializes a variable with all possible values and then we will although each line filter those already selected.

  You will probably have to change the names of form objects depending on you form, but here's my sample to test the code, https://files.acrobat.com/preview/eb0256dc-af30-4f7c-9187-469ba84464a4

• Generation and acquisition at the same time, acquisition of data USB-6356

  Hello

  I have a VI how is able to read entries with a USB DAQ-6356 and I use a generator of signals 'Agilent 33522 A '. I want to generate and acquire with the acquisition of data.

  In fact it works but not well, the frequency is not very stable and does not stop the 2nd loop with 1 (2nd is generating, 1 is Acquire).

  Thanks in advance

  P.S my VI isn't a state machine true because I need to fight against it at the moment.

  OK, so you're at 3 ms/s in writing and reading at 1.25Ms / sec and you wonder why he has a little difference in the frequency set?  Ideally, you want to read and write to share a sample clock but by selecting at least the same frequency clock (or one that is one multiple of the other) would go a long way to fixing this source of your error.

  The second source of error: you generate a contineous waveform.  unless you select 'whole number of cycles' there is a discontinuity when the end is reached at an arbitrary phase and the phase is reset to zero at the beginning of the wave.  DAQ assistant writing can "Use Waveform Timing" to adapt its sync settings to the dt waveform and the number of samples.
