  Specifically, the two simple solutions provided were:

  1 using the row_number, entitled Oracle ranking based on descending order of the inside telephone each empnum group. And finally selects the lines which has least rank (of least since that order is descending for phone).

  SQL > column alternatecontact format A20;

  SQL >

  SQL > SELECT empnum, alternatecontact, relationship, phtype, phone

  2 from (SELECT a.*, row_number() over r (PARTITION BY empnum ORDER BY phone / / DESC))

  3 FROM xxc_contact one)

  4. WHEN r = 1

  /

  EMPNUM ALTERNATECONTACT RELATIONSHIP PHTYPE PHONE

  ---------- -------------------- ---------- ---------- ----------

  Daryl Dixon EN work 7777777777 123457

  Home 123458 Maggie Greene CH 6666666666

  2. with the help of MAX, Oracle automatically assigns the maximum phone for all the rows in each group of empnum. And finally selects the rows with the maximum phone. Order by clause is omitted here intentionally. You can find out why.

  SQL > SELECT empnum, alternatecontact, relationship, phtype, phone

  2 (SELECT a.*, MAX (phone) over (PARTITION BY empnum) rn FROM xxc_contact one)

  3 WHERE phone = rn

  4.

  EMPNUM ALTERNATECONTACT RELATIONSHIP PHTYPE PHONE

• How to retrieve text messages deleted from the Iphone 5

  How to retrieve deleted messages of I Phone 5?

  Unfortunately there is no way to recover messages text deleted from an iPhone, unless you had a previous backup in iTunes before delete you messages. Restore this backup would be the only way to recover deleted messages. Once they are deleted they are gone forever, unlike the Photos that you can pick up if accidentally deleted by restoring their from the album "recently deleted".

• Retrieve the random record from SQL and also an ORDER

  I need a query that is able to get X amount of random records from a database of SQL2008, but I also want those results to then order by a field in the same table numberic, camp_priority

  I have

  	SELECT TOP #DisplayAmount #, camp_uid, camp_title, camp_text, camp_image_type
  	Campaigns
  	WHERE camp_uid IN

  etc... etc.

  then, at the bottom, I

  ORDER BY newid (), camp_priority

  The problem seems to be that I'm random records, but it is not ordered by the camp_priority

  Anyone have any ideas?

  Thank you

  Hey Adam,.

  I misread your original post, now I see how it was supposed to work, just posted below... got it works... works very well. If all goes well, is not to kill the CPU that this query will use a LOT... I'll just take a plu ;-) CPU

  Regarding the performance of NEWID() issue, I do not have a specific link, I was just hunting around different forums etc and found a few posts that talked about performance issues and who had a command I never saw that took a percentage of files with a lot of perfomance test graphic showing it was 10 times slow the other approach.

  I'll just have to see how it goes

  Thanks for the help

• LCDS retrieve a single record

  Hello guys,.

  I need your help

  im making Model Driven Development and want to know if there is a way to call an asynchronous service Synch NOT method.

  All calls are asynchronous.

  "

  var funcionarioToken:AsyncToken = new FuncionarioService () .getAll ();

  funcionarioToken.addResponder (new AsyncResponder)
  function (event: ResultEvent, token: Object = null): void
  {
  _funcionarioInput.DataProvider = event.result;
  },
  function (event: ResultEvent, token: Object = null): void
  {
  Alert.Show ("Associated failed service call:" + event.fault.faultString, "Error");
  }));

  "

  Is there a way to define the type of service calls back, for example, if I want to retrieve a single row in a table of database by ID, how could I do?

  var myVar:MyObjectType = event.result as MyObjectType;?

  concerning

  Marie Pierre

  Just as you specify a 'fill', you can specify a "get-item" that uses an identifier and returns a single element.

• Retrieve a single value from a file .lvm

  I have a large batch of files of worksheet whose name is a timestamp. I am writing a program that will get the value of a specific cell (the same cell in each file), coupled with the timestamp and each of them as a pair of coordinates, then save in a master spreadsheet. The goal is to extract a point each of the 700 files I and compile them into a single file.

  However, I've never used Labview to read the files before. I saw some stuff on how to read an entire worksheet in a table, but I was wondering if there was a way to say to Labview to look into a file and extract a single value. I open .lvm in Excel files, so, in my mind, I would be taking, for example, cell D2. Is this feasible? Should I read the entire worksheet in an array and use the index to pick it up on the table? If I do, how I would specify cell J2 as an array index (I have no experience with the berries in Labview either). In addition, if you have any tips on how to record easily 700 pairs of coordinates, that came together in the order, to a single spreadsheet, that is my next task.

  Essentially- I need to extract a single value of a spreadsheet in, ideally, the simplest possible. In addition, pointers on how to save the numbers gathered at each iteration of a while loop to a single worksheet are welcome.

  Thanks in advance for the help!

  FYI I have LabView v8.6

  You can't say LabVIEW to 'out' a specific 'cell' more you can tell Notepad to do. the .lvm files are just text files. When you open them in Excel, the column separator (default tabs) show to put the values in columns. In LabVIEW measurement file VI reading to read .lvm files. It creates the dynamic data, wrong data type that is next to useless. You will need to convert this type of data in a table by using the function convert of DDT. Or, you can use the VI read spreadsheet file. This will give you a table directly. You can just remove the specific item using the table to Index.

• How to retrieve the view coming from Onyx?

  Hello

  I started to use the Onyx project recently. That is truly amazing to see what he does. I wonder if there is a possibility to check the main view... let my try to explain this.

  I want to change the box of esxi5 - Advanced/Logging option to external syslog server.

  While in the interface graphics, I did my steps and Onyx prints the output:

  #---UpdateOptions-

  $changedValue = new-Object VMware.Vim.OptionValue [] (1)
  $changedValue [0] = new-Object VMware.Vim.OptionValue
  .key $changedValue [0] = "Syslog.global.logHost".
  $changedValue [0] .value = "tcp://x.x.x.x:514".

  _this $ = get-view-Id "OptionManager-EsxHostAdvSettings-456.
  _this $. UpdateOptions ($changedValue)

  This does not work as expected. I can throw it to powercli and it will introduce the option. This works only for this area special esxi. I want to create a loop that will change this option to each area of esxi in the cluster.

  The view that uses onyx is: ' Get-View-Id "OptionManager-EsxHostAdvSettings-456'»»

  That he already knows the moref / host of the view.

  But if I would like to have this in a loop, so it will do for each host, so how can I get this kind of view?

  So far, I could build only something like

  foreach($vmhostview_in_(get-view-ViewType_HostSystem-SearchRoot_(get-cluster_"xxyyzz").ID))

  {

  $changedValue = new-Object VMware.Vim.OptionValue [] (1)
  $changedValue [0] = new-Object VMware.Vim.OptionValue
  .key $changedValue [0] = "Syslog.global.logHost".
  $changedValue [0] .value = "tcp://x.x.x.x:514".

  $number = $vmhostview.moref.split("-") [1]

  _this $ = get-view-Id OptionManager - EsxHostAdvSettings - $nombre
  _this $. UpdateOptions ($changedValue)

  }

  Which is totally stupid approach I think it works... splitting moref...

  After a while, I noticed that

  http://pubs.VMware.com/VI-SDK/visdk250/ReferenceGuide/Vim.option.OptionManager.html

  Said OptionManager is owned by configuration manager. So that I could get the id from this point of view:

  ((get-vmhost myHost | get-vue).) ConfigManager.AdvancedOption). ToString()

  which will result in the output: OptionManager-EsxHostAdvSettings-456

  In order to have this I could make my loop at the end:

  foreach($vmhostview_in_(get-view-ViewType_HostSystem-SearchRoot_(get-cluster_"xxyyzz").ID))

  {

  $changedValue = new-Object VMware.Vim.OptionValue [] (1)
  $changedValue [0] = new-Object VMware.Vim.OptionValue
  .key $changedValue [0] = "Syslog.global.logHost".
  $changedValue [0] .value = "tcp://x.x.x.x:514".

  _this $ = get-view-Id ($vmhostview. ConfigManager.AdvancedOption). ToString()

  _this $. UpdateOptions ($changedValue)

  }

  Now I don't know that it was just a chance that I found the location of the view name or it's the way I'm supposed to find the name of view id. I wonder how other people treat such cases, if there is more easy way to do it. If someone could share its experience I would really appreciate it.

  Kind regards

  Greg

  There is not need to build these view ID as you see them from Onyx.

  In fact, I wanted to write this script like this

  $changedValue = New-Object VMware.Vim.OptionValue[] (1)
  $changedValue[0] = New-Object VMware.Vim.OptionValue $changedValue[0].key = "Syslog.global.logHost" $changedValue[0].value = "tcp://x.x.x.x:514"
  
  Get-View -ViewType HostSystem -Searchroot (Get-Cluster "xxyyzz").ExtensionData.MoRef | %{
    $optMgr = Get-View $_.ConfigManager.AdvancedOption  $optMgr.UpdateOptions($changedValue)
  }
  

  • Move the part that does not change with each HostSystem outside the loop
  • The ConfigManager is a table with MoRefs pointing to the respective managers. You can just do a Get - view with a MoRef and it returns the object that represents the Manager
  • From the object manager, you can now call the method

  BTW, you better see the last SDK Reference.

  You can find the HostConfigManager here.

• How to hide e-mail records when accessing content using WebDAV?

  Hello
  
  We use the hive as IMAP server, and we want to start using it to store files and documents. One of the questions that we found is that booty shows the user e-mail files in the WebDAV folder. How to hide these files to users?
  
  Kind regards
  Miguel

  Hello Miguel.

  You can't have that. However with the hive, we can store the document in the Inbox folder or create a subfolder containing document - even if it is unusual.
  So if e-mail folders are hidden you will not be able to access documents potentially stored inside.
  However, if this is a real problem, you can always open an enhancement request.

• How to retrieve a random record of DPL EntityStore of a unit test?

  Hello
  I want to write my code integration and unit tests. I want to get something random an EntityStore? How would you do that?
  
  If there is no direct way to get a random entry, is there a way to get an object by its position? In this way, I could determine the number and get a random input.
  
  I write a lot of code tests of the DAO layer where I need an entry that will satisfy my foreign key relationships.
  
  Thanks in advance,
  Steven

  Hi Steven,

  The LPD only supports Btree (ordered key) databases. So the only access is key lookup (exact or approximate) and scanner sequentially (forward or backward).

  You have probably thought about this, but one thing you can do is to get the keys of the first and the last and generates a random value between the two. Once you have generated a random key in the right range, you can approximate search of key using one of the methods entities() PrimaryIndex or SecondaryIndex.

  Entities() methods have signatures that allow to specify a beginKey. If you specify the beginKey, and null for the endKey, then the first returned entity will be greater than or equal to the beginKey. This is how a rough key search is made.

• How can I move a record from one computer to another

  I bought a license for the 2 computer to Adobe Photoshop CS6 extended.  I installed the product on two computers.  One of them is about to be replaced.  What should I collect from my old computer to transfer the license to the new computer?

  • On the old computer, launch Photoshop and click Help (Win) or Photoshop (Mac) > Deactivate
  • You can let the software installed but disabled, or you can uninstall. Your choice. It is not usable unless it is enabled.
  • On the new computer, install the software from the disc or download and it should activate automatically during installation. When you are finished, click Help (Win) or Photoshop (Mac) and if you see a menu called Deactivate option, then you know that it is enabled.
