• How to insert directly variable cursor in a table

  Hi all

  I use an attribute % ROWCOUNT cursor and I would like to insert the value into a table. When I try to do this directly, I got the error ORA-00911 invalid character. Inserting however more intermediate variable works. No idea why?

  Consider that I have a table called une_table with for example two rows and SOME_TABLE2 with a column of type NUMBER (10) for example. Then I try to run the code like this:

  DECLARE

  CURSOR cur_Test IS

  SELECT * FROM UNE_TABLE;

  BEGIN

  FOR c IN LOOP cur_Test

  DBMS_OUTPUT. Put_line (cur_Test % RowCount); -This line is ok

  INSERT INTO SOME_TABLE2 (COL1) VALUES (cur_Test % ROWCOUNT); - here, it fails

  END LOOP;

  END;

  However when I run it like this:

  DECLARE

  I have SEVERAL;

  CURSOR cur_Test IS

  SELECT * FROM UNE_TABLE;

  BEGIN

  FOR c IN LOOP cur_Test

  DBMS_OUTPUT. Put_line (cur_Test % RowCount); -This line is ok

  I: = cur_Test % ROWCOUNT;

  INSERT INTO SOME_TABLE2 (COL1) VALUES (i); - now it works

  END LOOP;

  END;

  I guess that the character '%' the cause of the problem. Maybe there is some way of backslash or something?

  Of course I can use ROWNUM value or another solution, I'm just curious as to why it does not work.

  Thanks for help

• Why "Paint" the Illustrator is ruining my lines? Help, please.

  I'm new to illustrator, but I managed to get around the bases of creation and illustrations coloring. The other day, I created a beautiful picture very well without any problems. But today, when I put my image highlight and go to object > Live Paint (while I'm able to use the Live Paint Bucket tool and the color of the image). He just screws the lines and makes it look weird.

  Before: http://s3.postimg.org/pnywj9f8z/rffref.png

  After Live Paint: http://s21.postimg.org/ywg20q9x3/safuqq.png

  Why is this happening?

  Tool width thw allowing you to create lines?

  Live Paint will not work with anything other than Plains traits (or no lines at all)

  What you can do:

  -Develop the traits of width varibale

  -make a copy of the work (so you can keep the direct variable traits) and painting and then direct the copy

• When to use the cursor for loop and the cursor (open, fetch, close)

  Hello world
  I have a small doubt about when to use the cursor for loop and when to use the cursor for loop and the cursor (open, fetch, close).
  Well, I'm not the difference between implicit and explicit cursor. So please tell me how I got to know, what to use and when?
  
  
  
  
  Kind regards

  All SQLs are analyzed, stored and executed as cursors. Thus, you will always use a cursor.

  The problem is that languages, such as PL/SQL, provide different interfaces to interact with the SQL cursor. As the ref, the slider interface, the interface DBMS_SQL slider interface and so on.

  Each of these interfaces offers different features. For example, using the interface DBMS_SQL allows binding dynamics and dynamic recovery. The Ref Cursor interface allows your code PL/SQL pass a handle to a reference pointing to the SQL cursor, to an external client. Etc.

  The fundamental reason for the use of an explicit cursor interface is mainly that you own and manage bulk made extraction output provided by PL/SQL cursor.

  With a cursor FOR , the motor loop of PL/SQL optimize the loop by extracting block a 100 lines both. However, you cannot access this collection in bulk directly inside the loop.

  With an explicit cursor interface, you specify the size of the extraction in bulk via the clause LIMIT , and you set the variable of collection to use. This allows you to use the collection directly variable inside the loop.

  However, the need to do - code manually in bulk collection - rarely occur in the daily programs in PL/SQL. A line of treatment is both slow and not well fits. And even if your bulk code collects lines, these lines must still be processed one at a time in your code. It is much more efficient and scalable rather write SQL code, and make the engine SQL the line of treatment for you.

• Custom pages OFA

  Hi all:
  
  I have a question about custom pages OFA release 12.1.2 (EBS 12.1.2/DB 10.2.0.4/z/O)
  
  Is it possible to migrate these pages without providing the developer with the APPS password?
  
  All the tools (freeware or other) that are useful for these migrations?
  
  Thank you

  XMLImporter works for the pages developed using JDeveloper also, so I did not understand your point.

  DBA can set the password for APPS in a unix environment (I'm sure it would be already) that are visible and accessible only for the user to super/appl. In your script, access the variable directly ($VARIABLE NAME) while XMLImport.

• Need advice to make a simple Flash video file. Trying to accomplish two things.

  I have some video files (.avi) that I'm trying to convert a Flash video format. I'm trying to export it to a Flash drive to be in a Powerpoint file. With that, I'm trying to accomplish two objectives:

  1. to have the small clip (15 s, 30 fps) constantly loop, like an animated .gif.

  2. allow the user to click on the video and made player slide left/right for ff / rew.

  The video itself is an animation of the turntable. One of our products makes a full 360 degrees turn. By allowing the user to capture and drag, it will simulate turning the model.

  So far, I have already achieved objective 1. I made a new Actionscript 3, any video file (embed flv in swf and play in timeline), and then made the video loop on the timeline. This seems to export properly, and video loop if necessary. The only thing I can't understand is how to "interactive" video and let the user drag left/right.

  For context, I have never used Flash before. Any help would be greatly appreciated.

  Essentially, it comes down to move the playback cursor in Flash based on the movement of the mouse. It certainly won't be smooth, however, you would need a clock to be responsible for moving your head to read and reverse space compression is very intensive CPU (reverse on the timeline). I would recommend having an upstream release and in advance of the video then you could return them, but if you're new to flash you are already in way over your head.

  Add a new layer and try to add this example script (or Download Source example here, registered in CS5):

  import flash.utils.Timer;

  import flash.events.TimerEvent;

  import flash.events.MouseEvent;

  Make sure that we don't raise this image twice

  If (! stage.hasEventListener (MouseEvent.MOUSE_DOWN))

  {

  stop the playhead

  Stop();

  set state (forward? back?)

  var movingForward:Boolean = true;

  var curFrame:int = 1;

  var mouseStartX:int; used later to determine the drag

  detect the click of the mouse and drag to the left or right

  stage.addEventListener (MouseEvent.MOUSE_DOWN, onMouseF);

  stage.addEventListener (MouseEvent.MOUSE_UP, onMouseF);

  create new timer to control the playback head, start it

  var phTimer:Timer = new Timer (33.0).

  phTimer.addEventListener (TimerEvent.TIMER, movePlayheadF);

  phTimer.start ();

  function to control the playback head

  function movePlayheadF(e:TimerEvent):void

  {

  curFrame += movingForward? 1:-1;

  validate the frame (60 total frames)

  If (curFrame > this.totalFrames) curFrame = 2;

  ElseIf (curFrame< 1)="" curframe="">

  Goto the next image

  this.gotoAndStop (curFrame);

  }

  function that controls the direction variable

  function onMouseF(e:MouseEvent):void

  {

  If (e.type is MouseEvent.MOUSE_DOWN)

  {

  the user began place start touching, record

  mouseStartX = int (stage.mouseX);

  }

  Else if (e.type == MouseEvent.MOUSE_UP)

  {

  user let the mouse go, determine the change in direction (by scanning stype)

  If (stage.mouseX > mouseStartX)

  {

  slipped right, move forward

  movingForward = true;

  trace ("move on now '");

  }

  ElseIf (stage.mouseX<>

  {

  crept to the left, move the rear

  movingForward = false;

  trace ("back up now '");

  }

  }

  }

  }

  It's pretty simple. In the link source of the example above, an object in the timeline (nice ugly red circle) is moving right plus 60 frames and then left on 60 images (120 total). Consider that your film.

  A clock at a speed of 33ms (30 fps). It's where he won't necessarily be too smooth with video. If you wear at 60 fps, then decrease the timer of the half (16.5ms), season to taste. Whenever the timer fires the playhead is moved, either forward or backward.

  For whether she should go forward or backward a simple variable (movingForward) keeps track of the last "swipe". The shot is simply captured when a user touches the screen (mouse/finger), moves in a direction and then leaves upward. If they moved to the left the direction will be reversed. If they moved to the right, it will move forward. This does not include nor this logic, but illustrates how you can watch the mouse for movement and 'do something' on this basis.

  A very simple validatior in the event timer function checks if the next image (in both directions) is valid and if it is not the case, it fixes it so that it remains within your length of video editing.

  Note there is a MOUSE_MOVE event you can try to hold on to who can literally let the user drag the video forward and back the amount, they drag their finger/cursor. Also if it is a kind of circular surface as a disc rotates, the direction of the user moving the mouse based on where they registration would change the direction in which they expect to move. Etc etc...

  Who should get your feet wet in how you should consider for your project.

• Direct local variable data VS

  Hey!

  I do LV Core 3 and hope someone enlighten me more... (Excersie 7-2 Solution more about 01:50 in the video to be more precise)

  According to this module, an indicator that is updated very frequently must be connected with direct data and not a local variable. Research assistance he said local variables to make copies of the data.

  It's a bit like this:

  1. I have an indicator that is 'coupled' to the X position of the memory.

  2. If I write a light directly he wrote directly to the X position of the memory.

  3. If I could write instead through a local variable... It would first create a copy of the data to write to the position indicator Y memory and then copy it to the X position of the memory?

  Thank you

  Peter

  Yes it's true.

  Now, imagine if you have a very large painting (and the elements of array must be States.map in memory).

  the first memory manager must find a place in memory where it can hold the table and you now have a memory more occupied by the local variable location.

• How to change the value of string clustered, to implement using the node value of property instead of writing directly on the flow of data or using the variable

  new to labview :-) and I have a problem when I want to change the value of a string in bunches, and I want to implement this using the node value of property instead of writing directly to the stream or by using the variable, enclosed is the picture.   No matter, I have change in cluster (control) or value of Popery out (indicator) cluster, the value (sensor 7) dataflow keeps unchanged even I gave the new value by value of property node. Thank you to give me some advice about this.

  

  Hi GerdW

  Thanks a lot for your answer. The reason I'm stubbornly tring to break the flow of DATA is: we have a test system that have about 100 screws, they have a few connected flow, some of them will be unbundling a cluster dataflow chain to check the value in order to make the different cases.  Now I want to insert user event by changing the control and influential cases during run time.

  As I initially uses a global variable (to control cases) instead of unbundle string data flow, it works well.  But then, I found there are a lot of screws that are using the string unbundle.  One of the 'lazy' means, I tried is to change the value via the property node (because that way, I did not need to find all the places where using the unbundle string and replace them with the global variable), then I noticed a problem with "dataflow", the value in the stream of cluster in fact will not be changed by changing the value of the property node.

  I did a test with VI simple (like the picture in last post), and after reading your advice, I tell myself that I need to understand the concept of "DATAFLOW" in labview, it seems that my "lazy" way can not work in this scenario.

  I have attached the criterion VI here, have you furthur suggestions on what I can do in this case?

  Mant thanks!

• How to assign the next value in the sequence directly in a variable?

  How to assign the next value in the sequence directly in a variable without using a table TWICE in PL/SQL.

  Nope... no obvious difference.

  This is because there is none: Oracle's SELECT sequence. NEXTVAL FROM DUAL under the covers. The direct assignment is just a convenient encoding for us, but it does not change the work that accomplishes Oracle.

  create sequence s;

  Is there a way to uncomment Employee.emp_department_id and insert data about employees using PT. 1 ???

  The correct method is to define the ManyToOne and set it to the appropriate Department. You can use find() or getReference() to get the service object with the ID.

  If you want to have a base for both Id mapping, then you must use the same column name.

  @JoinColumn (name = "emp_department_id")

  should be,

  @JoinColumn (name = "EMP_DEPARTMENT_ID")

  But since you have two mappings for the same column, you must set one of them write,

  @JoinColumn (name = "EMP_DEPARTMENT_ID", insertable = false, updatable = false)

  Or you could remove the ManyToOne and have just the base.

• Renamed 3 variables shared on the network in Subvi to starting RT VI, now they won't write?

  Hello world

  I worked on an RT program deployed to our cRIO-9024 with custom FPGA, and I changed the way in which the data is written to these three types of DBL 1 d. I renamed the shared variables ("shvars") in the library of the RT project shvar and also changed the target to the PC for the debugging of the function of the code written for them. I used a struct of conditional compilation to turn them off and something has been corrupted along the way and the second node broken shvar (node moved directly from project, no programming style) and caused a hard compilation failure in the Subvi. I got the compile error and go after the removal of the node of shvar entirely and placing him again the project and everything seemed fine.

  Soon, I bring the Subvi RT application instance and build my RT exe and deploy it. On the host PC, this second shvar now not get written in at all. I hunt and chase and decide that something is wrong with the deployment of the shvars. I redeploy all and even delete all 3 of the nodes of these shvars in the Subvi and place them again. Now, all 3 are not be written to. My next step is to move the shvars out of this sub - VI I put them in but this is recommended? Note that sometimes they seem to get written once and then are forever silent after that. Is this because I use the nodes instead of the function of programming with shvar addresses?

  Thank you.

  Edit: Notice the same level superior RT vi successfully wrote in 19 other shvars that I have not touched.

  -Very well, I shot myself in the foot and was in fact barking the wrong tree. Put shvar nodes in a Subvi was well and not at all related to the problem.

  The problem is that I had a bug in my code FPGA in a particular case, that could get him to stop putting valid data. Once I corrected this bug, everything returned to normal. I would like to delete this thread, but a little shy is right for you.
