• Correct use of the function in the pipeline?

  Hello

  No - this 'thing' you got is a hidden type of SQL Oracle automatically created to match the type of PL/SQL, that you used. SQL can only work with the SQL types defined at the schema level. But for functions PIPELINED Oracle allows you to specify the types of PL/SQL and it will create SQL HIDDEN types to make it work.

  A pipeline function should be treated as a table. You must use the SCOREBOARD operator

  Select * from table (myFunction);

  Try this simple example

  -type to match record emp

  create or replace type emp_scalar_type as an object

  (EMPNO NUMBER 4,

  ENAME VARCHAR2 (10),

  USE VARCHAR2 (9).

  MGR NUMBER 4,

  HIREDATE DATE,

  NUMBER OF SAL (7, 2)

  NUMBER OF COMM (7, 2)

  DEPTNO NUMBER (2)

  )

  /

  -records of the emp table

  create or replace type emp_table_type to table of emp_scalar_type

  /

  -function of pipelined

  create or replace function get_emp (p_deptno number)

  return emp_table_type

  PIPELINED

  as

  TYPE EmpCurTyp IS REF CURSOR RETURN emp % ROWTYPE;

  emp_cv EmpCurTyp;

  l_rec emp % rowtype;

  Start

  Open emp_cv SELECT * from emp where deptno = p_deptno;

  loop

  extract the emp_cv in l_rec;

  When the output (emp_cv % notfound);

  line of conduct (emp_scalar_type (l_rec.empno, LOWER (l_rec.ename),

  l_rec.job, l_rec.mgr, l_rec.hiredate, l_rec.sal, l_rec.comm, l_rec.deptno));

  end loop;

  return;

  end;

  Select * from table (get_emp (20))

• Correct use of the page-break-after

  Hello

  I don't know that it is a simple question for you.

  I have LONG pages of stuff on the web for people to print, and I wish they were able to print in a very specific way-

  I want to decide when the page "breaks".

  On the web, I saw simple HTML, but also JAVASCRIPT solutions - and I like to keep the solution as simple as possible.

  On this forum, there are a few discussions of pagebreak, but no simple and final solution.

  In your opinion, does the following work?

  < html >

  < head >

  < style >

  {.breakhere}

  page-break-after: always ;}

  < / style >

  < body >

  Have a look here http://css-discuss.incutio.com/wiki/Print_Stylesheets

  However, the best solution for printing, is to use a PDF file, what they are for. Create a PDF file containing the same data. You have total control over the printing format in this case. Have a look here http://www.fpdf.org/

• Correct use of the Type declaration?

  Hello
  I have a type declaration in a package as follows:
  

  type get_rec_type
  IS
    record
    ( upl_id    table_name.id%TYPE
    , doc_id    table_name.eff_from%TYPE
  ...
      );

  I referred to this guy in my statement of procedure as follows:
  

  PROCEDURE bulk_upload_prc
  ( p_rec OUT get_rec_type
  ...
  );

  Is this correct?
  
  The reason I ask is because I get the following error.

  You call the procedure as follows:

  EXEC schemName.new_bulk_upload_pkg.bulk_upload_prc;

  Yet, it is defined as follows:

  PROCEDURE bulk_upload_prc
  ( p_rec     OUT get_fbt_bulk_upload_rec_type
  , p_blob    OUT BLOB
  , p_srcfile OUT BFILE
  , p_max_rec OUT NUMBER

  Shouldn't you be calling him more in this sense then?

• Question about the correct use of the WM_CONCAT

  Hello
  
  I am trying to accomplish the following:
  
  from this
  

       ENAME
       ----------
       ADAMS
       ALLEN
       BLAKE
  ...

  and ends on this
  

       OLD_NAME   NEW_NAME
       ---------- --------
       ADAMS      AADMS
       ALLEN      AELLN
       BLAKE      ABEKL
  ...

  Basically, alphabetically sort the characters within each name. I have an intermediate step that seems promising
  

  select e.ename oldname, substr(e.ename, iter.pos, 1) newcharpos
    from emp e,
         (select rownum pos from emp) iter
   where iter.pos <= length(e.ename)
   order by e.ename, substr(e.ename, iter.pos, 1);

  Yields above
  

  OLDNAME    NEWCHARPOS
  ---------- --------------------
  ADAMS      A
  ADAMS      A
  ADAMS      D
  ADAMS      M
  ADAMS      S
  ALLEN      A
  ALLEN      E
  ALLEN      L
  ALLEN      L
  ALLEN      N
  BLAKE      A
  BLAKE      B
  BLAKE      E
  BLAKE      K
  BLAKE      L
  ...

  the characters are in the right sequence, I thought that all I had to do was to use WM_CONCAT (and replace the comma it inserts with an empty string) and I would like to make. I thought it would do: (replacement of commas left out for clarity)
  

  select oldname,
         wm_concat(newcharpos) newname
    from (
          select e.ename oldname, substr(e.ename, iter.pos, 1) newcharpos
            from emp e,
                 (select rownum pos from emp) iter
           where iter.pos <= length(e.ename)
           order by e.ename, substr(e.ename, iter.pos, 1)
         )
    group by oldname;

  but the sequence of the newcharpos is messed up in the process and, rather than the expected result, I get this:
  

  OLDNAME    NEWNAME
  ---------- --------------------
  ADAMS      A,S,M,D,A
  ALLEN      A,N,L,L,E
  BLAKE      A,L,K,E,B
  ...

  My question is, how to structure the last query so that the order of character as calculated in the inner query stays?
  
  Thank you for your help,

• Please help with a correct use of the "snapshot" function

  Hello

  I have recently updated to Pro - 9 11-Pro.

  With the 9-Pro version, I could take a snapshop of a portion of a page in a PDF doc and paste it elsewhere in the same doc (another page), or a different PDF doc.

  I just don't seem to be able to do the same thing with 11-Pro.  I don't know that there is a way.

  All your comments/opinions will be appreciated.

  Thank you

  pflor

  Hmm... I can take the snapshot with Acrobat 9, but stick that this does not work for me, as you describe. I can only paste like a stamp with the help of the: Tools > comment & markup > places the picture on the Clipboard as stamp tool

  In Acrobat 11, this tool is available under: comment > Annotations > add stamp [tool] > Place the Image on the Clipboard as stamp tool

• Question of weak references

  In general, I always use weak references when adding listeners. However this am I had tripped upward for some time, doing so and want to dig deeper and understand why the GC instantly removed the listener. So, here's the barebones of the class:

  public class smoke

  {

  private var clip: MovieClip;

  private var container: DisplayObjectContainer;

  public void Smoke($clip:MovieClip,_$container:DisplayObjectContainer,_x:int,_y:int):void

  {

  Clip = $clip;

  container = $container;

  clip.x = x;

  clip.y = y;

  clip.addEventListener (Event.ENTER_FRAME, update, false, 0, true);

  }

  private void update(e:Event):void

  {

  clip.Alpha-=. 01;

  If (clip.alpha < = 0) {}

  container.removeChild (clip);

  clip.removeEventListener (Event.ENTER_FRAME, update);

  }

  }

  In the constructor, when I add the listener enter_frame, using a weak reference, as shown, update never gets called... with the help of a strong reference works fine however. So, why the GC instantly removes the listener in this case?

  DOH! Nevermind, I thought about my own question as soon as I aksed it... is not always occur? Because the clip has not been added to the display list, the headset has been removed. The manufacturer just need: container.addChild (clip); and then the weak reference works as expected.

• Use of the Task Manager physical memory is not not to use processes

  I have seen this topic discussed it before, but I did not understand what is happening here.

  -J' have one windows server 2008 with 8 GB or ram configured, with the limit set to unlimited and booking made 8 GB.

  -When you look in the Task Manager, I see the physical memory to 88% and the bar bed to 7.10 GB.

  -Adding all process memory usage, it is only about 2 GB.

  -In another thread, that I read that it was because he had a deadline, and hot air balloon began.

  -J' I monitor the server via SNMP and have alerted all the time that this server joined more than 90% ram usage.

  -The Guest server is correct use of the physical memory Task Manager?

  -If it is not, and is caused by the ESX host, how can I fix it to properly monitor the comment server.

  

  

  The question here is how windows works,

  You reserve memory and don't have no limits, so there is no balloon showing VMs to appear that they have high memory use when they are not actually in some cases.

  Processes that Task Manager displays is not all that is running or being eaten, I know when working with SQL, you have FEAR that can use a ton on memory, but there is no process to show.

  Best thing to do is to run RAMMAP a sys internals tool that will show you exactly what is using the memory in windows.

• Correct use of snapshots

  Hello

  I would like to have comments about the correct way to use snapshots.

  Currently, I have a server ESXi 3.5 with 4 virtual machines.

  I use snapshots as follows:

  -J' still have 1 snapshot taken for each virtual computer

  -J' have regularly (before the size of the snapshot becomes too large) remove the snapshot and just after, take a new snapshot for each virtual machine

  -I will soon be able to make a backup of my virtual machines, but I don't now

  I recently started to monitor the size of my virtual machines, and they become several GB in just a few days.

  I wonder if it is efficient to always have a snapshot on each virtual machine.

  I'm starting to think maybe this snapshot should be taken just before to make a change on the server (installation of the software or other) to return to the State that we had before the operation, in the case where he's going poorly, then remove the snapshot after we have confirmed the operation went well, but should not exist at all times.

  Your comments are welcome! Thank you!

  Yann

  The snapshots are NOT backup anyway. If you use instant as replacement of backup then

  (1) you lose a costly storage space

  (2) that you have less reliable

  (3) you generate disk load high commit when snapshots

  What is the correct use of the snasphots:

  (1) you need to install a patch on your virtual machine

  (2) take the snapshot

  (3) install the patch

  (4) monitor behaviour of the system in case of patch broke something for awhile

  (5) commit instant if everything is ok, or go back to the snapshot if something bad happened.

• Question about the PDF reference

  Hello

  I don't know if this is the right place to discuss the PDF reference but I have not found another.

  In fact, I wonder if the positioning of the operators (operators of p.406 5.3.1 text positioning) text is correctly described in the PDF reference. Indeed, for the tx ty TD operator it is described that it has the same effect as: ty-TL tx ty Td. But after a few tries, it seems that it has the same effect as: +ty TL tx ty Td.

  Could someone agree with that?

  Thanks in advance,

  Joe

  PS: If there is a forum dedicated to the PDF reference feel free to move this thread

  There is a separate forum to discuss the language of PDF, which would include his documentation.

  The PDF reference is the name of the documentation for the PDF language published by Adobe.  It was published in version 1.0 to 1.7.  It has been SUPERSEEDED by the ISO 32000-1, the ISO standard for PDF 1.7 standard.  So you should consult this document for all future PDF language needs.

  And Yes, the TD is + ty.

• Removal of the dominant color and color correction to match the reference documents? the tutorial/guides/videos

  I searched some tutorials showing how to use SpeedGrade. I'm now comfortable with the UI enough to use after seeing these: http://www.youtube.com/user/AdobeTV/videos?query=speedgrade

  I am looking for tutorials that explain how to do a couple of things, first of all, I want to be able to remove color casts. In photoshop to do this you can use a curves layer and the use of the whole white point color chart and click somplace that is supposed to be white. and to the Prime Minister, you could do something similar with the color correcting fast. So basically that I'm looking for a way to target an area within a framework that should generally be grays, in the Anime, the eyes always be shades of gray, is as well as what I would target usually when you work with anime in photoshop first. If anyone knows a tutorial that shows how to do this type of color cast removal color correction in SpeedGrade could you please share a link.

  Some of anime the older 80 and 90 on the film, the film has aged and that's where the color cast came. There is also a loss of color information in all areas. For example in the image below. Heaven is supposed to be blue instead of green teal/sea.

  Another thing is back in the 80s and 90s many anime worked limited color palletes; something like maybe 16 colors in total, so many colors are used repeatedly. Thus, even with only a limited amount of reference material, I'd be able to get the corrections close. (I have no clips of reference for every single episode, only a handful of scenes from a handful of episodes).

  I have a few reference documents showing approximately what should be the color. So, my next question is if anyone knows of any tutorials/guides/videos showing how to use SpeedGrade to color correct a clip so that the colors match the colors used in a reference element

  I was also wondering on automatic correction based on an element of reference, although I'm guessing that this isn't always possible.

  When I looked at the websiminar: http://seminars.adobeconnect.com/_a227210/p738pxm9zs0/ about 43 minutes into it, a feature is shown that automatically adjust the color with a clip that contains a colorchart.

  I was wondering if a tool like that could analyze a start to clip at the end, to create a palette of colors used, and then compare that to the colors used in another clip and correct them. (a feature like this would be probably more useful/precise in anime that it would be long, but who knows.)

  Another question related to the user interface:

  I had a question, the only place where I see to access the colorwheels is in appearance, my video tab, I'm trying, just manages to adapt to 100% in the monitor.

  So I prefer to hide or reduce the different looks (maybe even with a keyboard shortcut) so that I can access the color tools it covers, I've attached a picture of what I'm talking about. I know pressing 'P' cache at the bottom and thought that maybe it already is a way to hide/minimize/reduce the aspect presets to access the tools behind them without narrowing down the size of the preview screen.

  

  It's a hard thing to do. SpeedGrade has an estimator of the matrix which aims to draw a camera shot in reference, but it only works if there is a graph of Macbeth in the framework - and you of course that.

  Short of writing a custom plugin, you will have to do it by hand - if there is a true 'gray' in the framework then the pickers for the 3WCC/FCC in first allows you to get the right temperature, and black/white levels can be removed to the limit with their pickers (assuming that something on one of the frames is supposed actually to be black or white). Fix nonlinear cast where the RGB layers are each affected by different curves is a much more complex process, and not automatable in everything I know. However, once the white point Beach and brightness are attached, you can still make some visual adjustments of the balance on a range of colors with secondary correction tools in the 3WCC.

  If you use the first and you want more help with these tools, please ask in the Premiere Pro forum.

• Using an array of references to Boolean controls as the input to a sub - VI edit propierties of orders...

  Hello

  I have a group of boxes and I want them to be exclusive one to change the objects visible to my vi when I change their State. So that my clear code, I decided to create a Subvi, which implements these features. My Subvi recives an array of references to objects that I want to change the visibility, an array of references to the boxes (to be change it's values to make them exclusive when one of the boxes change it is State) and an array of the values in the boxes in the last iteration (to be able to detect that we changed to true and false to others).

  The problem I have is that when I use a node property to get the actual values in the boxes in the Subvi (to compare to their State previus and detect changes) I will get a type variant, and not a Boolean value. I tried to set the mechanical action of Boolean references used as input in the Subvi as switch, but it doesn't seem to work. I understand this is cause of the Sub - VI does not know the type of Boolean values that will receive and assume the worst case...

  Is there a way to do what I want?

  I hope I've explained myself... Thanks in advance!

  There are several ways to deal with this, but it would be useful to see your code. Send the cluster in a VI, or those of the individual references boxes? It sounds like you are not using a strict reference. The workaround, since you know the type of data is to use the variant data and change the variant to a Boolean value, but this should not be necessary. Once again, some postal code so that we can be more help.

  Edit: looks like you are trying to hard-code the Radio buttons. You know LabVIEW has Radio buttons now, no?

• Why my PC keep forgetting passwords network and lies on the use of the correct connection to the NAS?

  My PC Windows 7 has acted weird lately because whenever I login to Windows and try to access my NAS drive or laptop, he asks the user name and password, even though I chose to remember it.

  The bit about the lie in question is on the NAS drive.

  The NAS drive is an Apple TimeCapsule (shock, I know), but it still works as a NAS device perfect. When I try to open it, it asks username and password as usual, but when I type in it properly, it appears saying that it is incorrect.
  The way I managed to get that player is now of type a random fake user and try to connect, for example comments. It says that I can not log in as a guest so I then type the correct user name and password after and it works...

  If for any reason any Windows is lying to me about the use of the wrong username and password. Also, I tried it on another PC and it works fine so it only affects this PC.

  Someone at - it solutions?

  Hi themichaelkc,
  
  I suggest you open the credentials manager and see if your saved credentials are correct.
  
  In addition, remove the passwords stored in the vault and re - enter the user name and password for automatic logon.
  
  See the following article for more information on the storage of passwords, certificates, and other credentials for automatic logon:.
