Deleting Large amounts of songs purchased

Is it possible to easily display what account purchased the iTunes song? I have several accounts that have authorized my computer to play music so I have songs from different iTunes accounts. One account in particular is no longer authorized to play, so I would like to delete all the songs purchased with that account. Is there a way to group all of the songs together to delete them quickly?
I do NOT want to go through "Get Info" and then click through all the songs in my iTunes library just to find the ones to delete.

IPad iTunes Stores App Freezes due to large number of songs purchased?

The iTunes Store App on my iPad 4 freezes when I go to " purchases" on the lower right hand corner of the screen. The screen remains blank, with the twirling icon in the middle implying 'wait.' I wanted to avoid doing a "restore" to the whole iPad, as everything else on the iPad but this works fine. After several days back and forth emailing with with Apple iTunes support, the Tech concluded it was beyond his/her technical expertise, and gave me the phone # for Apple Cares. Initial diagnosis after my first call to them was that I needed to do a 'restore' to factory setting because Apple won't push through an update to their iTunes Store App. So, I backed up the iPad to my using iTunes on my my PC and to iCloud, then called back. This time I worked with a very pleasant Apple Rep who stayed with me on the phone for over an hour running diagnostic tests, trying different things like rebooting my iPad, unplugging and resetting my Wi-Fi modem (I used AT&T UVerse for Internet and had already had techs out checking that after the first call - no problem there), going to iTunes on my PC, and a number of other things. After conferring with a senior tech, the Apple Cares rep said they concluded it was due to the large amount of songs I've purchased. I don't think of myself as a large music purchaser, maybe 4 - 5 songs a week since I bought the iPad new a year ago. So, I was wondering if anyone else has had this problem? Apple Cares was not able to tell me how to move songs out of "purchases" or whatever the bucket might be called where purchases are listed to clear this out if in fact it is the large number of songs there actually causing the iTunes Stores App to freeze. This is not an essential function, but I use it when I want to find the names of recently downloaded songs to place purchases into playlists. (I know, I should be able to remember the names, artists, etc. of the music a I purchase, but alas, no!) The nearest Apple Store is about 180 miles round-trip, and I won't get there for about two weeks. Incidentally, recently added songs show normally in the iPad's Music library. If anyone else has experienced this, was it fixed? If so how?

No, the problem still exists. As far as I know, the Case Number is still open. I've just not had time to set aside a day to bring the iPad into an Apple Store yet. It's about a 3 hr round trip, plus there'd be time walking to the store (it's inside a mall), and then the time spent while the iPad is looked at and hopefully fixed. Ugh!

What is the best practice of deleting large amount of records?

hi,
I need your suggestions on best practice of deleting large amount of records of SQL Azure regularly.
Scenario:
I have a SQL Azure database (P1) to which I insert data every day, to prevent the database size grow too fast, I need a way to remove all the records which is older than 3 days every day.
For on-premise SQL server, I can use SQL Server Agent/job, but, since SQL Azure does not support SQL Job yet, I have to use a Web job which scheduled to run every day to delete all old records.
To prevent the table locking when deleting too large amount of records, in my automation or web job code, I limit the amount of deleted records to
5000 and batch delete count to 1000 each time when calling the deleting records stored procedure:
1. Get total amount of old records (older then 3 days)
2. Get the total iterations: iteration = (total count/5000)
3. Call SP in a loop:
for(int i=0;i<iterations;i++)
   Exec PurgeRecords @BatchCount=1000, @MaxCount=5000
And the stored procedure is something like this:
BEGIN
INSERT INTO @table
SELECT TOP (@MaxCount) [RecordId] FROM [MyTable] WHERE [CreateTime] < DATEADD(DAY, -3, GETDATE())
END
DECLARE @RowsDeleted INTEGER
SET @RowsDeleted = 1
WHILE(@RowsDeleted > 0)
BEGIN
  WAITFOR DELAY '00:00:01'
  DELETE TOP (@BatchCount) FROM [MyTable] WHERE [RecordId] IN (SELECT [RecordId] FROM @table)
  SET @RowsDeleted = @@ROWCOUNT
END
It basically works, but the performance is not good. One example is, it took around 11 hours to delete around 1.7 million records, really too long time...
Following is the web job log for deleting around 1.7 million records:
[01/12/2015 16:06:19 > 2f578e: INFO] Start getting the total counts which is older than 3 days
[01/12/2015 16:06:25 > 2f578e: INFO] End getting the total counts to be deleted, total count:
1721586
[01/12/2015 16:06:25 > 2f578e: INFO] Max delete count per iteration: 5000, Batch delete count
1000, Total iterations: 345
[01/12/2015 16:06:25 > 2f578e: INFO] Start deleting in iteration 1
[01/12/2015 16:09:50 > 2f578e: INFO] Successfully finished deleting in iteration 1. Elapsed time:
00:03:25.2410404
[01/12/2015 16:09:50 > 2f578e: INFO] Start deleting in iteration 2
[01/12/2015 16:13:07 > 2f578e: INFO] Successfully finished deleting in iteration 2. Elapsed time:
00:03:16.5033831
[01/12/2015 16:13:07 > 2f578e: INFO] Start deleting in iteration 3
[01/12/2015 16:16:41 > 2f578e: INFO] Successfully finished deleting in iteration 3. Elapsed time:
00:03:336439434
Per the log, SQL azure takes more than 3 mins to delete 5000 records in each iteration, and the total time is around
11 hours.
Any suggestion to improve the deleting records performance?

This is one approach:
Assume:
1. There is an index on 'createtime'
2. Peak time insert (avgN) is N times more than average (avg). e.g. supposed if average per hour is 10,000 and peak time per hour is 5 times more, that gives 50,000. This doesn't have to be precise.
3. Desirable maximum record to be deleted per batch is 5,000, don't have to be exact.
Steps:
1. Find count of records more than 3 days old (TotalN), say 1,000,000.
2. Divide TotalN (1,000,000) with 5,000 gives the number of deleted batches (200) if insert is very even. But since it is not even and maximum inserts can be 5 times more per period, set number of deleted batches should be 200 * 5 = 1,000.
3. Divide 3 days (4,320 minutes) with 1,000 gives 4.32 minutes.
4. Create a delete statement and a loop that deletes record with creation day < today - (3 days ago - 3.32 * I minutes). (I is the number of iterations from 1 to 1,000)
In this way the number of records deleted in each batch is not even and not known but should mostly within 5,000 and even you run a lot more batches but each batch will be very fast.

How do I delete large amounts of photos from my ipad?

a

Are you using iPhoto on your iPad? Then deleting photos will depend on the album they are in and how they have been added to the iPad.
See this document for IOS 6 and earlier: iPhoto for iOS (iPad): Delete photos from iPhoto
If you also have a Mac, you can delete quickly large amounts of photos from your camera roll by connecting your iPad to your computer using USB and importing the photos into Image Capture, iPhoto, or Aperture. Then set the option to delete the photos after importing.
Photos you synced to your iPad can only be deleted by syncing again.
If you are using IOS 7 you can delete larger amounts of photos from your Camera Roll in the "Moments" view:
n the Photos.app you can select all photos in a "Moment" at once, by pressing "Select" to the right of the "Moment" name. Then press the Trash icon.
For example:

Deleting large amounts of data

All,
I have several tables that have about 1 million plus rows of historical data that is no longer needed and I am considering deleting the data. I have heard that deleting the data will actually slow down performance as it will mess up the indexing, is this true? What if I recalculate statistics after deleting the data? In general, I am looking for advice what is best practices for deleting large amounts of data from tables.
For everyones reference I am running Oracle 9.2.0.1.0 on Solaris 9. Thanks in advance for the advice.
Thanks in advance!
Ron

Another problem with delete is that it generates a vast amount of redo log (and archived logs) information . The better way to get rid of the unneeded data would be to use TRUNCATE command:
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96540/statements_107a.htm#2067573
The problem with truncate that it removes all the data from the table. In order to save some data from the table you can do next thing:
1. create another_table as select * from <main_table> where <data you want to keep clause>
2. save the indexes, constraints, trigger definitions, grants from the main_table
3. drop the main table
4. rename <stage_table> to <main_table>.
5. recreate indexes, constraints and triggers.
Another method is to use partitioning to partition the data based on the key (you've mentioned "historical" - the key could be some date column). Then you can drop the historical data partitions when you need it.
As far as your question about recalculating the statistics - it will not release the storage allocated for index. You'll need to execute ALTER INDEX <index_name> REBUILD :

Deleting large amount of emails locks up Mail?

I have a local mailbox ("On My Mac") that has about 50000 messages, and I want to delete about half of them. Deleting messages is always very slow (tbh, doing anything in Mail is very slow), but when I try to delete more than 5000 messages at once, Mail simply locks up on me.
I thought that it was just busy and would eventually come back, but I left it going overnight and came back to see it still locked up. So I force-quit and restarted it, only to find that none of the messages had been deleted or even moved to the trash. I guess deleting messages is an atomic process.
So my question is, how can I delete a large amount of emails without locking up Mail and without manually sitting there deleting one, waiting 5 seconds for the app to start responding again, and delete another, 25000 times?

I'm not surprised that dealing with so many messages chokes mail up.
You can try deleting messages in chunks about 1000 at a time.
also, you might want to try the following apple script.
<pre style="
font-family: Monaco, 'Courier New', Courier, monospace;
font-size: 10px;
margin: 0px;
padding: 5px;
border: 1px solid #000000;
width: 720px;
color: #000000;
background-color: #ADD8E6;
overflow: auto;"
title="this text can be pasted into the Script Editor">
tell application "Mail"
set mlist to selection
repeat with msg in mlist
delete msg
end repeat
end tell</pre>
Paste the script into Script Editor, select the messages you wish to delete in Mail and press "Run" in script editor. the script works by moving messages one at a time so I hope it shouldn't choke Mail up. However, it will take a long time to run.

How to check and uncheck large amounts of songs

Is there anyway/

hi y'all!
alternate technique if you don't want to check/uncheck all your songs (just a bunch of them at once):
select a large number of songs in the library (using either shift-click or ctrl-click). right-click on the blue mass, and select "check selection" or "uncheck selection".

Deleting large amounts of email easily

I subscribe to large email lists and have as many as 80,000 email in a mailbox. When I want to do some housekeeping and try to select over 100 or so messages, email stops and I have to force quit. It is very time consuming to select 20 at a time. Is there another way to select a large number of messages and delete them.

Delete large amounts of data from a table

I have a table with about 10 fields to store info for customers. Over time as we have added more customers that table has grown to about 14 million rows. As the data comes in a service constantly inserts a row into the table. 90% of the data is not revelent
i.e. I don't want data that is 3 months ago, but the most recent data is used to generate tracking reports. My goal is to write a sql to perform a purge of the data that is older than a month.
Here is my problem I can NOT use TRUNCATE TABLE as I would lose everything? Yesterday I wrote a delete table statement with a where clause. When I ran it on a test system it locked up my table and the simulation gps inserts were intermittently failing. Also
my transaction log grew to over 6GB as it attempted to log each delete.
My first thought was to delete the data a little at a time starting with the oldest first but I was wondering if there was a better way.I am expecting solutions apart from these :
1.Create a temp DB and copy the required data into temp Db and truncate the original.
2.Deleting in chunks(i.e.,1000 -10000 records at a time).
3.Set the Recovery mode as simple

I agree with Satish (+1)
This
is the right way to do it. Your database architect should think about this, and you can use partitioning by the condition for deleting (for example years if you are deleting old year data).
check this like for more details (but most of what you need
Satish already mentioned): http://www.sqlservercentral.com/scripts/Truncate+Table/69506/
* in the link you have SP named TRUNCATE_PARTITION which you can use

Adding large amounts of songs

Is it a bad thing to upload over 3000 songs onto a new iPod all at once, or will that likely mess it up? Like, will it overheat and melt a piece of hardware or something?

For a reference point, when I moved to my new machine, I dragged over 10,000 tracks into iTunes at once. It worked fine, after I figured out a couple of minor issues relating to Dual Core processors.

File transfer deleted a ton of my purchased files

While transferring my purchased files from my iPod to my iTunes library I noticed that a large amount of my purchases were deleted during the process. I have records for all the purchases that were deleted. What do I do?

just re-download them and you wont be charged as you have already paid once for those apps
any paid apps that were bought earlier, if you download them again no charges incur

How to delete a large amount of duplicates in itunes quickly?

I recently had a new hardrive installed, and during the multiple pc backups all my music was doubled, tripled, and quadroupled. Itunes doesnt have a system to delete a large amount of duplicates. I cannot sort them by 'date added' and use that method because they were all added at the same time. Is there a quicker and easier way of doing it rather than deleting all but one of the songs in each set? Because that would take a month to delete 6000 songs by hand....HELP!

The show duplicates/show exact duplicates features have been left out of iTunes 11. Rumor suggests they will be restored in the next build. In the meantime I have written two Windows scripts to make playlists of Duplicates and Exact Duplicates, either from a selection of tracks or the entire library. Note that, as with the iTunes feature, this list makes no distinction between "originals" and "dupes", you have to decide which is which.
There is also my DeDuper script for automatically removing duplicate copies but keeping one remaining copy of each set. This can preserve ratings, play counts, playlist membership, etc. which are lost in a manual clean up. Please take note of the warning to backup your library before deduping. See this thread for background on deduping and the script.
If you want to manually remove duplicate tracks use shift-delete to remove selected tracks from the library as well as the playlist. Keep one of each repeated group of files and don't send the others to the recycle bin unless you are sure that there are multiple files on the disc as opposed to multiple entries to the same file. Same advice to backup applies.
