In computer science, a null value represents a reference that points, generally intentionally, to a nonexistent or invalid object or address. The meaning of a null reference varies among language implementations.
The value null is written with a literal: null. null is not an identifier for a property of the global object, like undefined can be. Instead, null expresses a lack of identification, indicating that a variable points to no object. In APIs, null is often retrieved in a place where an object can be expected but no object is relevant.

In operations dashboard, I have a field with number values some of which are null. I would like to view the info using the number selector, displayed as a slider, but none of the null values show up e.g. the slider shows results from 0 to 200,000. How do I add an option to select the null values?
Thanks for the question and details about your use case. Unfortunately, at this time there is not a way to include null values from a number selector (when applying a filter action to another element). This is a good enhancement idea, however. I will bring it to the team for consideration.
I am going to recalculate "NULL" to "No Data" (text) and that should do it but the data is updated regularly, so I will have to recalculate whenever the data is updated. Also, I have large datasets and the calculation is taking a very long time.
After calculating your current data, I would change the field to not allow values and set a default value of 'No Data'. That way all new data that comes in will have this field populated and usable. Just remind your editors to update this field from 'No Data' to whatever is appropriate when needed.
Hello. I have a filter and formula (below) and Alteryx is not identifying the null values, it returns data as if every record has a value in the EXT_TRADE_ACCT_NBR field, which is not the case. This field is formatted as V_string. Do you have advice? Thanks.
If a field is null, it will display a grey "[Null]" in the results window. Another possibility is that the field is empty and that can be tested for using the isempty() function. Try adding that to your condition and see if that works.
The null keyword is a literal that represents a null reference, one that does not refer to any object. null is the default value of reference-type variables. Ordinary value types cannot be null, except for nullable value types.
Actually in general I find it exactly the opposite. I find also or apply to be more clear. Right up front you say here is the value that this expression will have but here are some additional actions to perform. It is somewhat unusual to use it on null, but it is perfectly valid.
Hello, I need some help. I currently have flow that when an item is created or modified from the Project Budget Hours List it is than converted into the Jobs Budget Hours List. The issue I am having is any time a user leaves a field blank in the form/list the flow will fail because of a null value. The low works perfectly if all the field are filled but not every time will every field be filled. I was wondering if somebody can help me with producing a value of 0 when a field is empty/null. My flow is Located below:
We are using the coalesce() expression which gets the first non-null value from a line of items. So coalesce("Dan","Steve","Mark") would return "Dan". If you have coalesce(null,"Steve","Mark"), then it would return "Steve" since it skips over the first null item.
Recently, I started creating a program for the company I work for. Just as background info, I'm still a student and a beginner programmer, so my solution is probably not recommended and I didn't know how to do it otherwise, but it works and I'm not going to be judged for it because it's a student job totally unrelated to programming.
The thing about the program is, it's going to be run on multiple different computer with different screen sizes and resolutions (800x600 and up). To make sure it takes as much of the screen as possible without losing any part of the program, I set the layout to null and hard-coded everything using relative values.
The program is kiosk-style and I first get the screen size values and go from there (for example, off the top of my head, the left-side menu takes an eighth of the screen, the top bar 2%, etc.). I also use font metrics to make sure the components are sized correctly and that everything gets displayed nicely.
My question is: why is it so frowned upon to make the layout null instead of using the layout managers? (I was told on some forums that this is a horrible way of doing things) I know how the layout manager works and know how to use the different layouts, but for the requirements of this program (multiple different resolutions, custom button shapes and placements, text changing on the components when you change language, etc.), I couldn't see myself using the layout managers to do it all.
How do you more experienced programmers use the layout managers in a situation like this? And what do you do when you want a button to be somewhere specific and other components somewhere else specific that don't really match any of the predefined layouts?
There are some common tricks. BorderLayout is a great layout to start with. Sometimes you might use it at multiple levels--often with just 2 or 3 components in it. That's because it's really good at giving all but one area the minimum required area and giving everything else to the CENTER.
More often than not, when a null layout is used, it also implies that all positions and sizes are hardcoded to a single value, so no flexibility at all is given. This means that changes in window size, language, font size, display density or any other related parameter have no effect on the layout and you get the usual ugly effects: empty parts of the window; tiny, unresizable lists; buttons with their labels cut off; ...
It sounds like the work you do should really be done by the Layout Manager. Either find one that does that (my personal suggestion would be MiGLayout, which does a lot and is easy to use) or write your own.
hmmm trick should be by mixing LayoutMangers and by usage of numbers of nested JPanels that each could have diferrent Layout or not, really depends of number of JComponents, that allows you to create GUI that looks like as layed by using AbsoluteLayout but with same look/output to the GUI for every screen resolutions and ratio (4:3, 16:9, 16:10)
Pretty much every name offers some possibility for being turned into a schoolyard taunt. But even though I'm an adult who left the schoolyard decades ago, my name still inspires giggles among the technologically minded. My last name is "Null," and it comes preloaded with entertainment value. If you want to be cheeky, you will probably start with "Null and void." If you're a WIRED reader, you might move on to "Null set." Down-the-rabbit-hole geeks prefer the classic "dev/null."
One of my iPads keeps populating with a message every time I open Square for Restaurants that says:
Password Required for "(null)"
and then asks for a user name and password. I've tried various different Square User names and passwords, I've tried my iCloud user name and password... Nothing works. I tried calling Square customer service and they told me to update the app. Tried that, didn't fix it. I also made sure the iOS was updated, not that - didn't fix it. It's just the one iPad. I have 2 other iPads in my restaurant and they aren't having this issue.
I don't even know WHY I try calling customer service because they NEVER help me and I always know more about their system then they do. Alas. Has anyone else had this issue?
This has just started happening to me in the last week. We did as Square suggested and it worked for a few days but now it is back. We only have 1 Ipad with Square POS. Today we deleted the app, reinstalled and reset everything else, checked everything had the latest updates and it worked for a bout 2 hours and now it is back again. Any other suggestions as this is driving us mad!
So we spent the rest of the day having to tap cancel every 3 seconds just to use the Square app. This only started last week when we started using Square and it only appears when we are using it, saying that at the end of day yesterday I deleted a load of unused apps (we don't have much on there anyway) and left the bare essentials. I deleted the Square app and cleared history and cache and updated anything that needed updating then reinstalled Square and (fingers crossed) it has not reappeared. We are also having internet issues so I am looking into changing provider as well. Photo is attached and I will let you know how the next few days go. If it happens again I will do the iPad nuclear option. Thanks for your help.
I'm having the same issue and finding it's related to one of our epson printers, whenever I configure it, this starts happening. Did you find a resolution? I've wiped our ipad and updated to latest ios, reinstalled square, so far nothing.
Just to follow up, I believe this is actually related to iPadOS version. We have a new ipad running 16.6 with no issue, we have 2 ipads recently upgraded to version > 17 that has this occur. Maybe a bug with the newest version comms with the square printer interfacing.
Fortunately for me I did everything that Chip said and we have not had an issue since, I did do the full IPad reset but I also think partly mine was also an internet provider issue as we are in a very bad area. Sorry I can't be of anymore help. We have had a connection issue with Square the last 24 hours so I hope things won't change.
