Group by groups but the resultset is not ordered
Group by groups but the resultset is not ordered. The very first answer is to use order by. But in some databases group by brings ordering automatically. Is it possible to order without using order by?Is there an option of database for that purpose?

The only way that any relational database will guarantee an ordered resultset is by adding an order by to your statement.

My young kids have ipads and since I updated the software, but they have their own icloud account, predictive text within their messages shows all my contacts from my iphone but the contacts are not listed as their contacts, how do I stop this?
I have deleted the iCloud account under my name on their iPads and replaced with their ones. Apple support said yesterday I needed to click the small 'I' by each name as it came up in the TO box and remove it. After doing rid for each contact under each letter of the alphabet it should remove them from latest contacts. Having done this, although I could not remove groups I had sent, I am not convinced they will not return once I have written a few texts, any ideas?

The wi-fi on my ipod touch is connected but the internett is not working! Help
Soo annoying, it's connected but the internett is not working. I don't know what to type in or what to do, so I need help.
Are you 100% positive you are connected? Head to Settings - Wi-Fi and tap the > next to the network you are connected to? What is listed for an IP address? If it's in the 169.x.x.x range, it means your iPod did not properly receive a valid IP address via DHCP from your modem/router. So the 169.x.x.x address is a self-assigned one.
This can usually be resolved by a reboot of your router. You can do this by unplugging it for about 30 seconds. After it powers back up, try reconnecting it. It wouldn't hurt to try a reset of your iPod as well. To do this, press and hold both the Sleep/Wake and Home buttons together long enough for the Apple logo to appear.
See here for more troubleshooting suggestions.

I have a VI and an attched .txt data file. Now I want to read the data from the .txt file and display it as an array in the front panel. But the result is not right. Any help?
Attachments:
try2.txt 2 KB
read_array.vi 21 KBThe problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does. -
I am trying to read my iMessages from my iPhone 4S on my iPad 2, but the messages do not show up on my iPad 2. I made sure that the receiving email address is the same on both devices and both are signed into my single Apple account.
Is it possible that the person who sent the message to your phone sent it to your phone # instead? Try sending a message to your phone via the email address and see if it shows up on the iPad.

i have purchased itunes match but the cloud will not load on my ipad 4.it works on my iphone 5 & it originally worked on my ipad.the only music that will show up is stuff that i bought from the itunes store.any ideas on how to get this to work?
On the MBP, in iTunes, switch to Song view and enable the iCloud Status column by pulling down View > View options and selecting the option for "iCloud Status." Close the small window. Look for any tracks that have a status of "waiting." If you see several of them disable iTunes Match while holding down the Option key. Quit iTunes, wait a few seconds, then open it again and turn iTM back on. Let it compelete the scan. Wait until all tracks that are "waiting" have a status of either "matched" or "uploaded."
On the iPad, turn off iTunes Match then launch the Music app and let the contents clear out. Power cycle the iPad for good measure, then re-enable the service once all the tracks in iTunes have been processed. -

I have just bought a new computer and i am transfering my music from my ipod onto my new computer, I have put the files from the music option from my ipod onto my computer. alot of the songs have come across, however there is alot of songs that havent. I have noticed that the m4a files come across but the mp3 does not. the new computer has windows 8 on it, which is very new to me. when i try and play the mp3 files, it will open them up in a different programme and will not open in itunes. does anyone know what i can do?!?!!?!?!
THANKSHave you looked at the previous discussions listed on the right side of this page under the heading "More Like This"?
BTW this is the iPod touch forum -
I have attempted the recommended fixes; power off the phone and I have deleted the email account and readded the account. I also signed into the email account. The problem is not witth my email account. This is a very disturbing problem. I purchased the iphone to reliably communicate. I have no idea which emails are sent since they are all appearing in my sent folder, but the receipient is not getting the email message. I regret upgrading to IOS7. This was not a problem under the older opperating systems. I tested this with my first generation iPad. I sent a message successfully to the receipient using my ipad 1. Does anyone have any other fixes to try?
The biggest concern is that the phone just randomly decides that certain emails are not sent! I am becoming very disillusioned with apple products - great way to destroy a good thing! The android market is looking more appealing everyday.I had that problem and seemed to have solved it by deleting my email accounts and then reinstalling. I think there was a HARD reset involved also, but since it was just after I got my new 4S (6 weeks ago), I'm not sure about the reset.

I’ve tried to update my i-Tunes version after the site suggested I should following my i-Pad Air being plugged into it for the first time. The update seemed successful but the program would not open at all despite switching off the PC and re-starting several times. I then tried wiping the original software from the computer and re-downloading from scratch. Each time I tried the download failed with a message saying “Service “Apple Mobile Device” failed to start. Verify that you have sufficient privileges to start system services” At this stage, the only way forward was to “abort” the download. This I have done now four times and the same thing happens. When I did finally manage to get an i-Tunes shortcut on my desktop, the program wouldn’t open saying: “i-Tunes was not installed correctly. Please re-install i-Tunes. Error 7 (Windows error 193)” Any ideas to resolve this?
Try the following user tip:
Troubleshooting issues with iTunes for Windows updates -
When the message arrives, the message tone sound that many times. How this problem can be solved? I installed the new version, but the problem is not resolved, the future is to be taken into account in the new version of this?
I'm not sure I understand the question, is the message tone going more then once?
Turn off repeat message alert here:
settings > notifications > messages > repeat alert > never
Some people have found this does not stop the repeat miessage tone,
if you are one of those then I suggest you contact Apple:

They may not respond, but hopefully will fix in uodate if enough people complain. -
I just purchase my first IMac with lion and I was trying to install a math program I bought 6 years ago. When I went to boot it off the disk while following the program instructions a window popped up with a note pad format with symbols and codes but the program would not download or open. How do I get this program to work? It is a mac compatible program by the way.
Your Mac probably does not know with which application to open the file and is opening a file with a text editor that really needs to be opened by the application itself. Try starting the application first, then use the File > open command to open the file.
As varjak paw comments, there isn't a "winmac" so that's not telling us anything.
Note that it is possible that software purchased 6 years ago may no longer run on your computer. Once we know what it is we can help more. -
I try to insert some images on a website but the images are not in the right color mode. I do not know what to do? and also I have 1200 images to insert so I can not change one after one. So I need to set up an action, but I donot know how to do it... Thanks
What is the problem specifiaclly?
If the images are intended for web use I would recommend converting them to sRGB which could be done with Edit > Convert to Profile or with File > Save for Web, but as including a Save step in Actions and applying them as Batch can sometimes cause problems I would go with regular converting.
You could also try Image Processor Pro.
