Boolean values

Does anyone know how Q&A handle boolean values? If a dataset includes a column with true/false values, what is the correct syntax for a Q&A query that filters on this value.
Carla Sabotta

I think it will work normally as other columns
for e.g. consider table students with column IsEligible having boolean values
Then Q/A query like "Count of students where IsEligible is true" should work fine and return count of students where IsEligible is true
Moreover If we set a proper data type of column then it should work more intuitive
E.g If we set IsEligible column to have data type as TRUE/FALSE and set word Eligible to be its synonym then Query like "Count of Eligible Students" should also work
Let me know if this answers your question.
Thanks,

How to use Boolean values from 2 different sources to stop a while loop?

I am working on a program for homework that states E5.4) Using a single Whil eLoop, construct a VI that executes a loop N times or until the user presses a stop button. Be sure to include the Time Delay Exress Vi so the user has time to press the stop botton.
I am doing this right now but it seems as though I can only connect one thing to the stop sign on th while loop. It won't let me connect a comparision of N and the iterations as well as the stop button to the stop sign on the while loop. So how would I be able to structure it so that it stops if it receives a true Boolean value from either of the 2 sources (whichever comes first)?
Basically, I cannot wire the output of the comparison of N and iterations as well as the stop button to the stop button on the whlie loop to end it. Is there a solution?
Thanks!

Look in the boolean palette for something similar to the word hightlighted in red above.

Error - '' is not a valid boolean value

I have been receiving the error message = '' is not a valid Boolean value quite frequently. It doesn’t matter which hierarchy I am in but it’s typically when I do an Add or Insert. When selecting ‘ok’ on the error message, I’m able to continue on with my work but was just curious what causes this error. Sometimes when this error shows up and I click ‘ok’, it will take me out of the DRM screen and into whatever else I may have open at the moment. Any thoughts or ideas? We are on version 11.1.1.2.103

As Murali stated-
It could be a property incorrectly configured, check all the boolean type properties and see if any of them are getting a string value by any chance.
Thanks

Boolean value mapping in udb

UDB does not support bit data types to my knowledge... what is a recommended way to map a boolean value to a udb database?

Hi,
In my opinon INTEGER (or SMALLINT) with 0 (false) and 1 (true) would be ok.
And then use "Map the Attribute as Object Type".

F:selectItems with default boolean value

Hi!
I have problem with using tag f:selectItems. I wrote converter in order to connect my items from the ManyChecbox list directly with my objects instead of strings. Now i would like to connect boolean values with my backing bean, so that when the page is rendered the default choice is marked. How can i do this?
<h:selectManyCheckbox value="#{myBean.selectedItems}" converter="MyConverter" >
<f:selectItems value="#{myBean.allItems}"/>
</h:selectManyCheckbox>

well the component is linked to your backing bean property 'myBean.selectedItems', which is probably a list or something. Whatever value in this list is true will be checked, so make the 'default' one true when you initially create the list (for example, in a @PostConstruct annotated method).

Cell with boolean value not rendering properly in Swing (custom renderer)

I have a problem rendenring boolean values when using a custom cell renderer inside a JTable; I managed to reproduce the issue with a dummy application. The application code follows:

I can post the table model and the other renderer if needed (didn't want to put too much code on the question, at least initiallty).
Should I render a checkbox myself for this cell in the custom renderer? I'm puzzled as I expected the default renderer part of the code to do this for me instead.
Thanks!

camickr
Thats because the default render is a JLabel and it just displays the text from the toString() method of the Object in the table model.What I meant to say is that I expected the JCheckbox not a String representation of the boolean value.
Thats because a different renderer is used depending on the Class of data in the column. Look at the source code for the JTable class to see what the "default >renderer for the Boolean class" is. Then you can extend that or if its a private class then you will need to copy all the code and customize it.At the end I looked at the code and replicated the functionality I needed. I thought than maybe there was a way to avoid replicating the same logic all over again in order to implement this functionality. Good advice, though.
see you learned nothing from your last posting. This is NOT a SSCCE. 90% of the code you posted is completely irrelevant for the described problem. There is abosutelly no need to post the custom TableModel, because there is no need to use a custom TableModel for this problem. The TableModel has nothing to do with how a column is rendererd.The custom table model returns the type of the column (giving a hint to the renderer on what to expect, right?) and for the one that had a problem it says than the class is Boolean. That's why I mentioned it:
public Class getColumnClass(int columnIndex) {
    // Code omited....
You also posted data for 4 columns worth of data. Again, irrelevant. Your question is about a single column containing Boolean data, so forget about the other columns.
When creating a SSCCE you don't start with your existing code and "remove" code. You start with a brand new class and only add in what is important. That way hopefully if you made a mistake the first time you don't repeat it the second time.That's what I did, is not the real application. I copy & pasted code in a haste from this dummy program on this forum, not the best approach as it gave the wrong impression.
Learn how to write a proper SSCCE if you want help in the future. Point taken, but there is NO need for you to be rude. Your help is appreciated.

Jose.

AudiCLip.play should return a boolean value

Java Experts,
looks like it's a bug in java, the audioClip.play method should return a boolean value indicating whether it was able to play the clip or not. Because sometimes the method doesn't play anything. Right now the method plays asynchronously that may be the reason that it returns a void. Thoughts???
Q.

i agree with you..i also encountered this problem sometimes the play method doesn't play and the programmer has no clue to figure this out programmetically...Looks like this problem has no solution..where are java experts in this forum??

Newbie - How to retrieve a "Boolean" value in a jsp via jsf ?

Is it possible to retrieve a Boolean value from a BBean from, from let's say a 'rendered' tag ?
class BBean
Boolean secure;
public Boolean getSecure() {...}
From the jsf:
<h:outputText value="#{somebean.whatever}" rendered="#{BBean.? == false}" />
How do I use the Boolean object in an expression like the one above ?
Note: I've simplified the example above, but I cannot use a primitive boolean for this, the objects I use
are generated with "Boolean"s and I have no control.
Thanks in advance !
Mark

You should just use boolean instead of Boolean;
class BBean
boolean secure;
public boolean getSecure() {...}
<h:outputText value="#{somebean.whatever}" rendered="#{bBean.secure == false}" />

The Boolean value getting null?

Hello EveryBody........
Any one help me why the Boolean value gives always null instead of false;
what will the default value of this.........
       private Boolean result;
     public Boolean getResult() {
          return result;
     public void setResult(Boolean result) {
          this.result = result;
     }please help how to set the default false without initialize private Boolean result = false;

Default initialization for Instance reference variable is null reference .
Default initialization for Instance primitive variable is depends on its type.
Local variable should be initialize before they used.
got it?
But this question should be in "New to Java" this forum.

Boolean Values in CALL TRANSFORMATION id ?

Hi,
I have Boolean values of the XSDBOOLEAN Domain, so ABAP->XML "id" transformation returns "True" and "False" for these values. What I need are "X" and " " respectively.
The questions is: can I use the modified transformation "id" to replace the "True" and "False" with "X" and " ", and how the modified transformation should look like?
Thanks, Srdjan

I couldn't find domain XSDBOOLEAN in our system, however you should use the values defined in the Value range tab.

How to generate pulse during changing boolean value?

I need to generate short pulse during changing boolean value from 0 to 1. This pulse is needed to reset counter.
I was trying with Event Structure with Value Change but I think that I did something wrong.
Maybe sambody can give me some tips to do it in other way?
Thank you in advance.

We assumed you wanted a pulse when a front panel button (boolean) was clicked.
I am still not sure just what it is you want.
Do you want a single pulse when x is greater than 4?
You don't need an event structure for that.

Changing a boolean value based on two buttons

I know that this is a ridiculously simple question, but I've been having trouble with it.
How would you set a boolean value based on the input from two other boolean values? Essentially what I want, in pseudocode, is this:
boolA = true
if (boolB)
     boolA = false
if (boolC)
     boolA = true
It should be really simple to do, but I can't figure it out. The problem is getting it to stay false, for example, after boolB goes back to false, and not just to have it only momentarily go to false. I want it to stay false until boolC goes to true, regardless of what boolB does after that. Any advice?
Thanks,
Logan Williams

I would say implies is close to what was asked for. However, the only issue is that for the case where both B and C are false, the logic shows that there is no change to A. It is initially True, but if it happens to be False because of further changes, there is nothing in the If statements to change the logic. And that is what is asked for. That the Result stays False even when B goes back to False. But the Implies function says that F and F must be True.
As described
B         C         Result A
T          T          T (because C is evaluated 2nd)
T          F          F
F          T          T
F          F          x (initially T, but the code shown and what is asked for is actually no change from previous state)
   Implies Truth Table
B         C         Result A
T          T          T
T          F          F
F          T          T

I am reading the status of 10 lamps from a serial string. My VI
returns a boolean value according to the status of the lamp. Now I
need to time the on time of each lamp. As soon as a lamp turns off it
should save the time and start adding the time again once the lamp
comes on again. Once the VI is closed and reopend the on time should
appear in the VI for each lamp. And once a lamp comes on it should
start adding to that time. I should also be able to reset the time and
I should also be able to enter a number of hours that a lamp has been
on already. Any suggestions ? Thanks

Hello wv,
do you want someone to develop a program for you? Then you have to pay him/her :-)
Some hints: Make an array for your time values. To reset a timevalue you just need to clear it. To have an offset you just set it in that array. Let the status-vi run in a loop and get the time difference for one loop iteration. Add that delay to the timevalues, if the status of the lamp is on. If you need that timevalues after restarting your VI you should think about a subVI for saving and reading the timevalues.
Best regard,

Java & Acces: pass boolean values

Ok I'm totally new at this so the following text will hopefully be understandable. I hope you guys can give me a hand over here.
The case:
I'm making a java function that has to create a new user of my database. This user is supposed to get a name, a password and can have 4 functions (Administrator, Author, Reader, Coreader).
To identify the 4 functions i used a checkbox in my database. So when the box is checked the person is a Admin/author/... Now I was wondering how i can use Java (using a query) to set these values checked or non-checked.
I thought I'd use booleans, however, my compiler says there is a General Error (all the names of the columns are right, so that's not the deal, my database is working properly and such, ...)
So here's my code:
(note that i used these marks ' ' here for the booleans, i tried all kinds of things such as dropping them, using them, ... it doesn't seem the problem...)
public void addNewUser(String username, String password, boolean admin, boolean author, boolean reader, boolean coreader)
String query1 = "UPDATE user SET username = '" + username + "' AND password = '"
+ password + "' AND administrator = '" + admin + "' AND author ='" + author
+ "' AND reader ='" + reader + "' AND coreader ='" + coreader + "'";
try
stmt = global.createStatement();
stmt.executeUpdate(query1);
global.showMessage("The new user, " + username + ", has been added successfuly", "Succesfuly added");
catch(Exception e)
global.showError("An error has occured while connecting to the database" + e.toString(), "SQL Error");
finally
global.closeConnection();
Hope you guys can help. Thanks a lot!

It's possible to do this; it's just that your SQL syntax is completely wrong. An SQL UPDATE statement looks as follows:
UPDATE table SET column1 = value1, column2 = value2, column3 = value3 WHERE expression
You're using 'AND' instead of commas, which is the first thing that goes wrong. The second thing that goes wrong is that you're building the SQL statement from bits of string and values. This is a habit that many novice programmers use, and open the door wide for SQL injection attacks. I you do this sort of thing on a web site, you could end up with your customers' credit card details being exposed.
But because you're just passing the boolean values into the string, they get expanded to a string value, hence TRUE or FALSE. However, because they are string literals, they should be surrounded by single quotes.
This brings us to the third problem: you're using an UPDATE statement to insert a new record. Use an INSERT statement instead.
It would be better to use a PreparedStatement. In this case, your code would look as follows:
PreparedStatement stmt =
    global.prepareStatement( "INSERT INTO user " +
            "( username, password, administrator, author, reader, coreader ) " +
            "VALUES ( ?, ?, ?, ?, ?, ? )" );
    stmt.setString( 1, username );
    stmt.setString( 2, password );
    stmt.setBoolean( 3, admin );
    stmt.setBoolean( 4, author );
    stmt.setBoolean( 5, reader );
    stmt.setBoolean( 6, coreader );I have no idea whether this will work: I don't know Access, and booleans are not a standard feature of SQL. I also don't know whether Microsoft have created their own flavour of SQL, as they are wont to do with any standard.
All in all, though, you have to really work on your SQL. Three major mistakes in such a simple piece of code means that you don't understand SQL syntax. You may copy and paste this for your assignment, but unless you understand what you're actually doing, you're going to run into trouble again very soon.

Digital waveform to boolean value

Hi, I have a digital waveform and I want to be able to light up an LED on the front panel every time the waveform is high...
What is the best way to do this?
I know there is a vi that converts a digital waveform to a 2D boolean array, but I just want a single boolean value.
Thanks!
Sunny

Hi
In reference to my previous post, you can just leave the inner for-loop, but you have to extract the 4 channels.
Just have a look at the picture.
Hope this helps.
