• Newbie: PL/SQL, combining values of columns of different recordings?

  Hello
  
  I want to extract a certain number of documents and then combine the value of one of their columns in a single record.
  
  Leash so tell the following sql statement returns multiple records:
  
  Select NAME, ADDRESS from userstable where ADDRESS = 'N6 0JG.
  
  
  What I get in return is a file that looks like this

  Hello

  Since you already have it in a cursor, we will just add another and make the two loops.

  First let's make a cursor to address list

  cursor c_address is
  Select distinct ADDRESS
  of userstable;

  Now, let's make another slider that will loop through all the names to each address. I guess that your table contains multiple addresses. Note You can pass parameters to the cursor.

  cursor c_names (p_addr in varchar2) is
  Select NAME, ADDRESS
  of userstable when the ADDRESS = p_addr;

  Now we can put it all together. You can do everything you need with the result. I just stuck to a release on the subject.

  DECLARE
  CURSOR c_address
  IS
  SELECT DISTINCT address
  Of userstable;

  CURSOR c_names (p_addr IN VARCHAR2)
  IS
  SELECT NAME, address
  Of userstable
  WHEN address = p_addr;

  v_namelist VARCHAR2 (2000); -Do this as large as you want
  BEGIN
  FOR x IN c_address
  LOOP
  FOR y IN c_names (x.address)
  LOOP
  -make a list of names with spaces
  v_namelist: = v_namelist | ' ' || y.NAME;
  END LOOP;

  -Add address and a comma at the end of the list
  v_namelist: = v_namelist | ', ' || x.Address;
  Dbms_output.put_line ('v_namelist =' | v_namelist);
  END LOOP;
  END;

• bits of address multiplexer loop

  Hello!

  I have 16 multiplexers (ADG 406) with an address of 5 bits for the doors. However the first bit is the bit to activate it, and I always

  'on', so my question is for the remaining 4 bits in the address.

  Q: is it possible to create a cycle or loop so that the 4-bit address changes for each multiplexer?

  Example: 1 Multiplexer has address 0000 for door 1 in the 1st pole, then in the second loop I want

  Is to have the address of 0001, for example!

  Is this feasible?

  Any help or link to similar questions would be very apreciated.

  See you soon.

  Hi rsilva,

  Use something like this:

  

  The value of the indicator to display binary and you will see the individual bits...

• How to use Boolean loop values from 2 different sources to stop awhile?

  I'm working on a program for homework indicating E5.4) using a single eLoop Whil, build a VI that runs a loop N times or until the user presses a button. Be sure to include the time delay Exress Vi so that the user has time to press the stop botton.

  I am doing this right now, but it seems I can connect only one thing at the stop sign onto th while loop. It won't let me connect a comparison between iterations and N as well as the stop button at the stop sign onto all loop. So, how would I be able to structure so that it stops if it receives a true Boolean value of one of the 2 sources (both whichever)?

  Basically, I can't thread the result of the comparison of N and iterations as well as the stop button the stop on the loop about button to put an end. is there a solution?

  Thank you!

• Passing a Boolean true that once a loop

  Hello world

  I'm pretty new to LabView and worked on a project that uses it. I met a problem in one part of my code. I have a graph of wave form that reads tensions since a data acquisition card and I find the rising edge of it. When the edge flushing occurs, it produces a Boolean true am I on a case structure to trigger another event. The problem is the waveform data collection is in a time loop, because I think it takes to continue to accumulate data, it sends continuously the Boolean true until it is no longer on the front. I just want to send a boolean true when it hits the rising and wait until it hits again, because it's a sine wave.

  I apologize that I don't have code to post right now, but any ideas or diagrams would be very appreciated!

  Do not reinvent the wheel.  Just use the Boolean crossing PtByPt VI.  The output of your rising edge comparison goes into this VI and you specify "fake-real" sense.  The output will be TRUE on the first sample of your forehead.

• Having trouble getting Boolean button While loop is not updated

  Hello world

  I'm trying to understand how continuous image capture works. So, I tried to implement a simple while loop with a button "continuous Capture". It seems that when the "Continuous Capture" button becomes false, the while loop could not update and stop. No idea how to solve this problem? Thanks in advance.

  Kind regards

  Move Boolean Capture next to the loop of inter 2.

• Time to toggle Boolean in while loop?

  Hey everybody,

  I need to toggle a Boolean variable for a short period of time (~0.5 seconds, but it doesn't have to be exact, as long as it can be changed) when the trigger signal is on.

  -basically the variable Signal should remain False until the trigger indicator is True

  -Signal must turn to True for ~0.5 dry and turn return False after

  The program must be substantially while loop (loop data acquisition). Using the calendar could affect the acquisitive data (not shown in the sample program).

  I tried to do this with a case structure and sequence flat but in vain. Any suggestions are welcome. THANKS FOR YOUR HELP!

  

  Something like that?

  

• Sharing of Boolean values across while loops

  I'm new to Labview and I try to use an angular encoder as a type of switch.

  I want to take measures continuously from the angle of the encoder and turn on an analog output signal, each time comes in a certain angle. When the encoder drops from this angle, I need the signal to turn off.

  To do this, I try to run two parallel while loops. We measure the angle of the encoder, while the latter creates the output signal. What I want to do is to put a logical statement in the measurement loop that will record 'true' if the maximum angle is reached. I try to get that 'real' statement in the loop of generation of signals as a trigger to turn on (using a case structure and the "DAQmx Start Task.vi") output. The question I have, is that the 'real' statement cannot exit the loop to measure up to the end of the loop. But since I'm running it continuously, the loop ends. Thank you.

  Create a local variable of the Boolean in anxiety.  Right-click on the local area and select change reading.  Put this inside the loop else local.  If you have a loop that writes to the Boolean value and a loop that reads from the local.  Now you can remove the wire that comes from a single loop and feeds on the other.  Then your curls will work in parallel (if there is no other dependencies of data between the two loops).

  As an alternative to local variables, you can use a queue to transfer data from one loop to the other.  A loop (the producer) will write to the queue.  The other loop (consumer) reads from the queue.  See the examples on the architecture of producer-consumer for more information.

• creation of the loop for a Boolean value

  Hello
  
  I'm still a beginner at so forgive me if this sounds simple...
  
  I created 16 Boolean values with all the false value.
  
  Now with a loop for, I try to create 16 buttons, and when each button is pressed, the respective boolean compared to this button will change to true. Looks something like below:
  
  Somehow, this does not work... someone can point me to an error in the coding? Thank you very much!
  
  
  

  Couple things...

  It is standard for a button work onRelease, not delivery.

  -at your service delivery made reference to the button. Not the root
  panel mounting as you probably want to target. The real problem, however, is the
  the reference to I in the button. If you do a trace (i); within the delivery
  you will find that each button will trace 17. This is because the button don't
  not to maintain a local reference to i - just button refer to the final
  value of i in the main timeline... it's called scope. Sometimes issues of concern
  can be a real challenge. What you need to do is to create a local variable
  in the buttons and I store it in this variable.

  for (var i = 1; i)<= 16;="" i++)="">
  This ["button" + i] .i = i;
  This ["button" + i] .onPress = function() {}
  This ._parent ['status' + this.i] = true;
  }
  }

• When boolean is set to skip a step in the while loop

  Hey guys,.

  I have a program that controls a fan that pumps gas at a certain speed. This entire process is run in a while loop. When we move from the gas by a gimbal which is located on the front, we immediately jump in a cycle of breakdown and then goes back to the pumping of the gas at the rate previous, but we do not know how to achieve this. Can you guys give advice? Thank you!

  Sincerely,

  The Z.

  Hello,

  A shift in your loop register may be able to achieve this type of functionality. If wire you the switch in the shift register to the right and register in the structure in case of wire left shift, the loop must travel once more before moving on to the HP gas. Here is a link to a tutorial on shift registers:

• My 'stop' boolean does not stop my time looping

  I don't know why, but my program just continues even after I press the 'stop' button in the front panel.

  I can't understand why. (I'm a newb extreme of LabVIEW, so apologies if this is something extraordinarily obvious.)

  There are two ways to fix this:

  1. Add another case of pylone2 value change event. Now put the pylone2 inside the new case and it wire to the Terminal to stop the loop.

  2. Add a constant to the connection of the clock in the upper left corner of the structure of the event.

  In solution 1, that the loop runs only if one of the triggers of the case, since you don't have an event for the stop button it will not play when it is pressed. In solution 2, adding a constant of millisecond to the timer, there will be a created event timeout, the loop will run at this pace of MS, then the stop button will be seen by the program. If that's all you have in your loop, then option 1 is probably the best to use.

  When I started with LabVIEW, I went through a lot of examples, take a look to find examples in the Help menu and take a look at the fundamentals - loops and Structures.

  I hope this helps.

• Which allows a Boolean variable being true in a while loop

  Hello.

  I have 12 real switches.

  The default value of them is false, and I need to somehow allow one of them turn out every time.

  To clarify, if for example I click on don't pass any 2 (and turn it to true) to start its ok, because that is only turned on, but when I don't click on switch 3 (and turn it to true) so I need not turn the switch No 2 (go to false) instantly.

  I have studied the software just to start and am not all familiar with all its functions, then I'd be really grateful for the help.

  Thank you

  Denny, Yes

  You can get the the real valye for this Boolean in an array of boolean. you just need to follow the steps that I've shown in the picture below.

    

• Boolean latch to Stop function Test loop

  Hello!

  I'm working on a project to control a Chroma programmable AC Source model 61604 with LabVIEW, and I'm having a problem where my "Stop Test" button is not to behave exactly how I would want only it. I changed the mechanical function to a switch, which is unfortunate, because I really prefer it as a lock.

  He must penetrate several loops in many cases, so I currently use local variables that required me to change the function of the button with a switch, but I'd rather keep it as a button.

  Is it possible to enable a button closure go through several places? The event structures are usable for that without waving curls? (I found that one of my event structures back was a loop of its function so I'm a little more circumspect on them now)

  Thanks in advance,

  Anthony

  What is the problem with the help of the trigger?  Latch means it will reset after reading, thats why he is not compatible with local variables.  How does he know to expect that every local variable has been read?  And some may never be read.  You can actually do the swtich behaves like a lock if you wire a false to a local variable of this, but make sure that it runs only after all of your other loops have finished.

  You can use a notifier as a way to send a notification to each loop button is pressed.

  You can keep a structure of the event to be a holder of a loop by plugging in a zero to his node timeout.

• Judgment of multiple while loop running at different rates to stop using the single Boolean stop button

  Hello

  I'm on the block diagram of 4 loops, do different tasks. They are independent of each other, but need to see the unique front panel - some of the wonders of labview!

  Now, I want to have a unique stop button which will in fact be a back button to return to the main screen by stopping all four loops on the block diagram. I used the stop button (switch released) with local variable to stop the three other loops. He stops the vi but it is not a good stop vi to stop properly and the grid on the performance of the front panel. Now all loops run also at different rates, so it is not necessary that all loops are stopped immediately when one of the loop is stopped. Can't really think of a better way. All the ideas!

  Kind regards

  Austin

  Variables local is ok in this case, but you will need to keep the control in switching mode (no lock).

  A better solution would be to have all the loops as a structure of event all listening value stop change. Or have the Stop value change event generate a user defined output event or similar.

• How to convert boolean 1 d table to leave everything in a loop?

  I had initially a > = block to get out of this while loop and it worked fine. I wanted to add a second condition to exit the while loop, using a > = block, so I run both in a block of GOLD, and I get a cut wire. I don't understand why one works but the other does not.

  The background does not work with or without the block of GOLD.

  

  If your goal is to stop based on the GOLD of the two State, more than 720 'OR' any value that is greater than or equal to 0.5, you will need to 'OR' the picture coming out of equal or greater than 0.5.
