How to (or can I even) concatenate BLOB

One practice for storing images files is creating a table with a column (named IMG) of the BLOB data type, then inserting each image into the table. The result is the table contains multiple records:
ROW1: img1
ROW2: img2
ROW3: img3
ROW4: img4
Now, for some reason I need to concatenate the image data (not combine them), just concatenate them one after another, into one record, then store it in the table, logically speaking, it will be like this: img1 | img2 | img2 | img4
When I need it later, I'll issue a SELECT statement such as
SELECT img into v_img from TABLE_NAME where id = '12345';
next I need to separate and restore the v_img back to its individual image, i.e., img1, img2, img3, and img4.
I just wonder can I even do this?
Thanks

Hello;
I don't believe that's possible in the database. A blob is just a set of binary-data. One set.
I would post more about your exact requirements.

I just got iphone 5c and i am not happy with it. It uses to much data and i don't even know how. I can't get the ringtones i want for my contacts.I got it on my free upgrade but i want to take it back and get something else but where i got it they say i can't because i don't have the earbuds and i have serches or them. now i am suck with a phone i don't like at all until my next upgrade. this is very dishearten

1. If you are this unhappy with that phone, and the lost earbuds is the only thing stopping you from taking it back, why do not just buy some earbuds. That way you can get rid of that phone. It all depend upon how much you want to get rid of that phone.
2. Yet if you are stuck with that iPhone, here is something might help you to control the data usage. By design, iPhones do turn off WiFi when they go dormant. So if a download is in progress and so forth when the phone goes dormant, it will switch to use cellular data, if this setting is left on. Therefore, from multi-sources I have learned that if you keep your iPhone connected to a power source, then it will stay connected to the available WiFi.

I am trying to manage family sharing and I get a warning "invalid apple ID" that accounts can participate in one Family at a time. How can I add my daughter when I can't even access my account?

Your best bet would be to try resetting the password to the account that you would like to use via iForgot
Once you log in to that account change the email address to anything, it can even be fake its just a placeholder
After you do that you will be free to change your old email address on your appleID to the new one that is now free to be used as it is no longer attached to the other account.

You buy one download and one download only, it is your responsibility to backup your music.
it has always been very basic to always maintain a backup copy of your computer. Use your backup copy to put everything back.
If for some reason you have failed to maintain a backup ( not good), then you can transfer itunes purchases from an ipod: File>Transfer Purchases

Hi, I recently changed my username for my iTunes/iCloud account. Can anyone tell me how i change the username on my iCloud iPad? When I go onto setting to change it it keeps the username grey so I can't even select it?

Welcome to the Apple Community.
In order to change your Apple ID or password for your iCloud account on your iOS device, you need to delete the account from your iOS device first, then add it back using your updated details. (Settings > iCloud, scroll down and hit "Delete Account")
Providing you are simply updating your existing details and not changing to another account, when you delete your account, all the data that is synced with iCloud will also be deleted from the device (but not from iCloud), but will be synced back to your device when you login again.
In order to change your Apple ID or password for your iCloud account on your computer, you need to sign out of the account from your computer first, then sign back in using your updated details. (System Preferences > iCloud, click the sign out button)
In order to change your Apple ID or password for your iTunes account on your iOS device, you need to sign out from your iOS device first, then sign back in using your updated details. (Settings > iTunes & App store, scroll down and tap your ID)
If you are using iMessages or FaceTime, you will also need to log out and into your ID there too.

i googled for answer to resolve the zoom problem. all the anwers just told you to read links but didn't tell how to fix the screem back to normal then it can be able to go to Setting to fix the zoom funciton. HOWEVER, I accidentally found the solution myself by using a fingers or more
to draw circles clockwise on the screen....it will reset it normally. I spent hours trying to go diagonally, compressively still didn't work.

Thoroughly angry and frustrated. I've run out of room and need to make more to add more songs. Once and for all, how do I, if I even CAN, delete music from my iPod Nano WITHOUT losing them from iTunes?

You should take the time to familiarize yourself with the documentation that is available. You can "uncheck" a song in iTunes, and then do a manual update.

To delete files from your external HDD, attach it to your MBP and drag the unwanted files to trash and then empty trash.
Then you select the files that you want to transfer by 'drag and drop' to the external HDD and trash the files on your MBP.
Ciao.

IPhone 6 Plus display supersized. I can't even log on. How do I reboot and bring back to normal size window

my iphone 6plus display zoomed to a super size so much so I can't even log on now or get to the controls. How do I correct this?

My iPhone 5 did the same thing. Real pain if you restart. Does not change anything if you reset.
Go to settings, general and accessibility to turn of oversize text.

Without knowing what you have tried please open System Preferences - Sharing - File Sharing and select File Sharing. If you still have trouble you can call AppleCare in the morning when they re-open. You have 90 days of telephone support if you haven't already bought AppleCare.

How come i can't open the sim tray even if i use the small pin?

how come i can't open the sim tray even if i use the small pin?

Press firmly and push either the sim eject tool or a small paperclip straight in until the tray pops out.
If that doesn't work make an appointment at an Apple store.

How can I make Azure blob give me "206 Partial content" for mp4. Getting 200

I want a video for my web-site, so I am using html+JavaScript found on view-source:https://www.airbnb.com/
see id="pretzel-video"
and script starting from var video = $("#pretzel-video");
The point is - if I copy html+JavaScript on my web-site, I can get "206 Partial content" from airbnb.com, i.e. the video hosted on airbnb.com starts streaming immediately.
The same thing happens if I upload the same video to my domain hosted on arvixe.com and S3 Amazon
The only provider that doesn't give me 206, but responds with 200 instead is Azure blob
This is unacceptable, because the user has to wait until all the video is loaded.
So how can I make Azure blob give me "206 Partial content". I am hosting web-site on Azure also.
I am using airbnb.com video in all three cases to exclude possible errors related to codek etc.

Hi Chao
Azure Blob storage supports return 206 response if you're using API version 2011-01-18 or later .
However if
don't originate the request which means you can't specify this using the request header , you can set the API version globally
for blob service within a storage account by using " Set
Blob Service Properties" API ,
If the above still couldn't solve your issue, we suggest you please contact Microsoft Azure technical support for further assistance.

HT1451 how do I create playlists now of my downloaded music. Used to drag from "recently dowloaded" to playlist. Can't even find the dang songs!!!!!

how do I create playlists now of my downloaded music. Used to drag from "recently dowloaded" to playlist. Can't even find the dang songs!!!!!

However, my troubleshooting issue is that I also want the songs in my concert playlists to go in order of how they were performed at the concerts.
Give them a track number.
Each time I number them within the playlists the song's number also changes within the Library Music list.
And? I'm not seeing the problem.
However, I can not figure out how to make true copy. I've already tried dragging the song to my desktop, then dragging the new copy back into iTunes. I've even tried renaming the duplicate copy and dragging it into iTunes. Why won't my iTunes make an individual duplicate copy of a song?
How do you have iTunes manage your music? If you drag a song to the desktop it may just be moving the file to the desktop.
Command+R to reveal the file in Finder. Command+D to duplicate the file in Finder. Drag the duplicate to iTunes to add the second copy. Not that I totally understand where the issues lie and feel this is likely not the best remedy...
