What is the size of a rowversion

Hi,
https://msdn.microsoft.com/en-us/library/ms182776.aspx states :
...Is a data type that exposes automatically generated, unique binary numbers within a database. rowversion is generally used as a mechanism for version-stamping table rows. The storage size is 8 bytes.
A bit futher it states
A nonnullable rowversion column is semantically equivalent to a binary(8) column. A nullable rowversion column is semantically equivalent to a varbinary(8) column.
Now I am confused, shouldn't it be a binary(64) since there 8 bits in one byte ?

Now I am confused, shouldn't it be a binary(64) since there 8 bits
in one byte ?
??? Bits, what for bits ??? A binary(8) can store 8 bytes, see
binary and varbinary (Transact-SQL)

I have an early apple tv. Will it support netflix streaming? Also what is the size of the newest apple tv's hard drive? And, will my current apple tv be able to use the icloud services?

I have an early apple tv. Will it support netflix streaming? Netflix does not show on the internet tab on the AppleTV display.
Will my current appletv connect to icloud services, synch, etc.?
Also, what is the size of the current appleTV's hard drive?

1. No to NetFlix and ATV1
2. If you mean your ATV1, no.
3. If you mean your ATV1, there are more than one hard drive size. If you mean the new ATV2, it doesn't have a hard drive.

For best performance what's the size of an image to be stored in database?

Hi all,
can any one tell me..for best performance what's the size of an image to be stored in database?
is it <256kb or >256mb?
when i google we can store image as varbinary(max) and its limit upto 2GB..
Can anyone exlain it?
is it performance wise better..
thanx in advance..

Your question does not seem apparently meaningful. If you need to store a 5MB image in the database, you store a 5MB image, not a 200 KB image or a 200 MB image. Business needs always trumph performance.
Not surprisingly, the larger the image the more resources it takes to read and write it.
What is a meaningful question is whether you should use the FILESTREAM feature or not. The cut-off limit here is usually given as 1MB. That is, if your images typically exceeds 1MB you should use FILESTREAM and access the data through Win32
API. If your images are generally below this size, you should stick to regular T-SQL.

What is the size and number of documents we can upload to a document library at one time

HI
what is the size and number of documents we can upload to a document library at one time.
like we have scenario , we developed a custom solution to scan and upload documents to sharepoint sites doc library.
here we face issues when user try to upload 100 documents with the size of each doc 2-3 MB, at one time.
adil

Hi Adil,
The maximum number and size of documents to upload in a document library is determined by a setting in Central administration. You can go to Central administration -> Application Management -> Manage Web Applications -> Select the Web Application
-> Click on General Settings in the ribbon. Scroll down and you will see "Maximum Upload Size" section. The maximum value that can be set is 2047 MB.

What is the size limitation of Oracle JDBC Statement?

Want to know how large is the limiation of one complete SQL insert string can be place
into a JDBC Statement and can insert the big record successfully. I tried up to 13K, JDBC still can accept it. Does some experienced
guru can tell me what is the size limitation
for insert or update SQL string JDBC can accept it?
Thanks a lot.

None known. More than 10 GB. Please note Acrobat is not for server use (I mention that because you mention C# and experience shows it is often preferred for backend development).

It could be any size you design for. It could be a 8.5x11 sheet of paper folded into three panels so that you end up with 6 panels for page content.

What is the size of a string data type

Hello,
What is the size of a string data type. Also what is the maximum size upto which a text file can grow?
Thanks in advance
cooldude

Hi cooldude,
the size of a string is given back by the function "String size". Strings are dynamically managed in LabView.
The max filesize is limited by the used filesystem. FAT-based systems are limited to 4GB (or was it 2GB?), other filesystems may allow more...

What is the size of the local DB in general?

Hi All,
What is the size of the local DB in general (for a user developer/mobile client)

Hello
In version 8.1 , you are usually above 1GB, but all depends on the amount of data routed per your responsability/position.
The difference between a developper local db and a user local db comes from the repository tables downloaded in the developper local database.

What are the size limitations in Predictive Analytics - regression charts

I'm trying to display the trend chart for an Exponenential Regression Prediction and I got the following error. The Regression itself runs OK and provides a summary, but I can't display the data on a chart.
There's only 1 other related posting- Error PAS10066 and it doesn't provide much more info than is in the error itself.
Does anyone have extra info on what the size of the limitation is? Is it something that can be overcome with extra RAM etc?
I'm using the desktop version of PA 1.19, and I'm on a 64 bit installation of Windows 7 with 8GB of RAM, processing a csv file with 1.1 million rows.
I've used some filters in the Prediuct workflow to cut down on the amount of data being processed, and I got past the PAS10066 error and am now getting a max call stack size error - can't find anything related on SCN for this one.
Many Thanks
Astrid

Hi Astrid,
Thanks for reaching out.It could be a out of memory issue.
If you increase the memory that SAP Predictive Analysis is allowed to consume.
Go to the location where SAP Predictive Analysis was installed. In my case it is:
C:\Program Files\SAP Predictive Analysis\Desktop
Here you find a file "SAPPredictiveAnalysis.ini" - open this in Notepad and change the
"-Xmx" parameter to approximately half of our PC/laptops memory.
For instance in your case you could try with: -Xmx4096m
I have outlined this is a few more steps here:

Hope it works for you.

What is the size of capture window for MX440-VTD8X?

I am trying to figure out how best to resize video I have captured with my MX440-VTD8X. For the application I am using (AVISynth) I need to calculate the PAR (Pixel Aspect Ratio), for this I need to know the size of the capture window for my video capture card.
I think that this card uses a Philps SAA-7114H, although I cannot be certain as MSI don't seem to publish this fact anywhere. (I found a few references to the 7114 via Google so that is the best lead I have had so far).
Anyway, even if I knew it used a 7114H that doesn't much help as I can't find any published data that tells me what the capture window (in microseconds) is for this card. The WDM driver might modify the window so how, so I can't just look it up in the datasheet for the 7114H.
I am looking for figures for the capture window for both PAL and NTSC,
could someone please help?
many thanks,
Kevin

To quote from the article I have been using which gives step-by-step instructions on how to calculate to aspect ratio ..
(Pixel Aspect Ratio, Source Aspect Ratio and Target Aspect Ratio)
"To determine your source PAR, you first have to know what the aspect ratio of the capture window of your capture device is. This capture window is fixed, but again it is rarely exactly 4:3. The device always digitizes the same area of your video and resizes it to the size you set in your capture application. The raw captured height is always 480 lines for NTSC and 576 for PAL. The width of the capture window has to be determined. A table with known values (and a more elaborate explanation) can be found in section 5.4. A method for determining this value yourself can be found in chapter 11.
Once you know the capture window width, the Image Aspect Ratio of your device can be calculated as:
PAL IAR = (4 / 3) * ([window width in µs] / 52.0 µs) / (576/576)
NTSC IAR = (4 / 3) * ([window width in µs] / 52.6555 µs) / (480/486) "
The 'window width' is given for some capture cards in the guide, but unfortunately not the MSI one I am using, and the 'window width' does vary from one type of capture card to another.
Without this information I am at a brick wall. There is a method to determine the window by using a PAL DVD player as the source video, playing some test image, the problem is that I only have an NTSC DVD player so I can't use that technique,
this is something that the manufacturer must know, but unfortunately they rarely publish it,

What is the size of particles in the color sphere toner for the laser jet 2605dn?

I want to know the size of the particles on the color sphere toner for the HP laserjet 2605dn. I want to print color decals on this printer but I have to use ceramic pigments that will survive the firing at 1400 farenheit...Black, Cyan, Yellow, Magenta. I am not thinking on the iron oxide on the toner, I am thinking in Cobalt oxide, and 3 other oxides. Can I modify the settings or fill the cartridges with ceramic pigments? Can you refer my question to the person handling the toner specifications?
Thanks,
Miriam

Thank you Alan and know you are right. I really can do all I need with my netbook and ereader and do not need the ipad. I think I just wanted something new and felt I may enjoy using it a lttle more than the netook. But it would be a waste just to buy one when I donlt acutally need it And, donl't think it is worth the extra money for me the get the 4g wireless capability since I doubt I would really need it often.
I may treat myself to the Ipad for the color, touchpad and fun to use but it is very expensive considering how little it will do for me no more than the things I want it for. It woudl be and expensive luxuray, I can do without. I actually need t learn how to use more of the function avaiable first. Maybe I should take up playing games and learning to take digital pictures so I can at least load them. If I could learn to do that and take a decent picture, I could start selling back all the "stuff" I have purchased on ebay. haha - I do have a nice doll collection, I would like to sell. I just do not have room for anything else. That was the primary purpose for the Kindle Ereader I bought and enjoy so much,
But, I will hold onto the thought for a while and see how it goes and what other comments I get, If I think I cannot live without it, then I will have to rethink which one to buy, I coud get the 32 g if I did not have to pay for the 4g wireless. And, if I knew I could get help to teach me how to use and enjoy all the functions, I would give it more serious consideration. My granddaugther got one for Christmas and that was what got me interested in it. I love the size of the screen and it had good color and was fast. She even had an application where she could write her notes and it would convert into typed words. That was a neat feature, If you could print it?
But thanks again for your comments and I will check later to see I get any other feedback.

What is the size limit of mbox files in Leopard Mail 3.0 ?

What is the file size limit of mbox files in Leopard Mail?
e.g. a main folder -- that contains no actual emails -- but contains many sub-folders each of which have an mbox file.
Each mbox file has a limit, but because the main folder has several mbox files/subfolders, it means that the size of the main folder gets very large.
Question: is there is a size limit for the main folder, even though there is no mbox file associated with the main folder (since it merely acts as a folder for subfolders)?
Question: what is the practical limit for each mbox file -- theoretical and practical? i.e. what size should we not exceed in order to avoid corruption?

I've been researching for the same answer. And technically speaking, I don't have one. In the past, I've "heard" that the mailbox size limit was something like 1GB for Mail (OS X 10.3) and then something like 2-4GB for Mail (OS X 10.4). I have searched all over the place in technical documentation and can't really get a good answer. I'm almost leaning towards believing that there is no limit, based on the fact that the database that mail is using (particularly for OS X 10.4) is BerkeleyDB 4.2.52 and that DB doesn't have a size restriction. I'm not sure if that is the only factor involved though. I've tried researching the limits for KMail, which is the mail program that runs on KDE (Linux), which is the program that Mac OS X Mail is based off of... and I can't find anything there either. Most people say, "It's a free app, so don't expect much," but I'd rather use Mac OS X Mail than most anything else. I hope that maybe someone from Apple... or someone else who can reference technical documentation can help out. Thanks!

What is the size limit for a video using VZW Messaging

I've tried a few times to send videos with VZW Messenger but every time it gets rejected for being too large. I don't see a setting anywhere and these videos aren't that big. What's the trick??
Thank you,
Ron

I may not simply be a matter of size, it may also be a matter of resolution.
In the past, I have tried to send a video which was not able to be sent because it failed to meet the size restrictions of the texting app. I tried repeatedly to shorten the video until it was not worth sending. I then lowered the resolution of the phone when taking another video to a lower resolution and was able to send the video even though the file size was larger then the size of a higher resolution video I had previously tried to send.
I believe I had to lower the resolution to 640x480 in order to send the video attached to a text. Whether or not this is still the case, I do not know as I rarely send video MMS.

Restart and go into Disk Utilities from the Recovery HD (press COMMAND + R when you hear the chime). Then click on the drive (not the Macintosh HD) and the Partition tab. You should see the Recovery partition to click on to get information including size. You might be able to this info from the First Aid tab too. I can't remember.
