Get sum of fields using ListData.svc or API?

I want to make a call to ListData.svc or the API through a URL and get a sum of a field back based on the filter criteria I send. Is there a way to do this?

Hi,
There would not be such aggregation function in CAML query or OData query when sending a restful request:

http://msdn.microsoft.com/en-us/library/office/fp142385(v=office.15).aspx#sectionSection7
As a workaround, I would suggest you do the math in client side with the data retrieved.
Thanks

Tutorial on how to update list items using ListData.svc

Can you please point me to a tutorial which shows how to update a list item using listdata.svc and C#?
Sorry if this is FAQ.
I have found articles on read list... but I haven't found anything on update a list item.
val it: unit=()

when i try this I get an error 500
I created an ASP.NET web application that allows the user to modify data that is stored in SharePoint I rather not go into the reasons why this application was created but focus more on why doesn't the listdata.svc allow me to update a task item that was
created by a workflow collect data from user action.
1. The workflow creates the item.
I collect the item and update the item using the below code. This is not an OOTB approval workflow that is just the name I used. When I get to save changes I received the following error code.
Dim getApprovalItem As ExpenseApprovalRuleBasedTasksItem = spContext.ExpenseApprovalRuleBasedTasks.Where(Function(i) i.Id = Pam.ApprovalItemID).FirstOrDefault
If String.IsNullOrEmpty(getApprovalItem.AuditorApprovalValue) Then
getApprovalItem.AuditingComments = approvalComments
Select Case approvalDecision
Case "Approved"
getApprovalItem.AuditorApproval = ExpenseApprovalRuleBasedTasksAuditorApprovalValue.CreateExpenseApprovalRuleBasedTasksAuditorApprovalValue("Approved")
getApprovalItem.AuditorApprovalValue = "Approved"
Case "Rejected"
getApprovalItem.AuditorApproval = ExpenseApprovalRuleBasedTasksAuditorApprovalValue.CreateExpenseApprovalRuleBasedTasksAuditorApprovalValue("Rejected")
getApprovalItem.AuditorApprovalValue = "Rejected"
End Select
getApprovalItem.Outcome = "Completed"
getApprovalItem.Status = ExpenseApprovalRuleBasedTasksStatusValue.CreateExpenseApprovalRuleBasedTasksStatusValue("Completed")
getApprovalItem.StatusValue = "Completed"
getApprovalItem.Complete = True
spContext.UpdateObject(getApprovalItem)
spContext.SaveChanges()

How to create a document folder using ListData.svc

Hi All,
I've recently been put on a project where I need to use the REST services (ListData.svc) to retrieve and add documents to the document library. It all has been smooth sailing until I hit the point where I want to save a document in a path that doesn't exist.
I get an error if I try to save a file where the folder structure doesn't exist. I then went about it a different way trying to create the folder structure first. This also didn't work and I get an error message saying that the entity type is marked with the
MediaEntry attribute but no save stream was set for the entity. Not too sure what set for the save stream if I'm just adding a folder.
So my question is can a file be added to a folder structure that doesn't exist where it automatically creates the folders. If not can the service create folders?
Some sample code I've been using:
var folder = new SampleDocumentLibraryItem();
folder.Name = "Sample";
folder.Title = "Sample";
folder.ContentType = "Folder";
folder.Path = "/sample/folder1/folder2";
spContext.AddToSampleDocumentLibrary(folder);
spContext.SaveChanges();
Thanks in advance,
Damo

Hi All,
Finally managed to figure this one out. For anyone who needs source on how to create a document folder. Some sample source is below...
var folder = new DocumentLibraryItem();
folder.Name = "Folder Name";
folder.Title = "Folder Name";
folder.ContentType = "Folder";
folder.Path = path;
spContext.AddtoDocumentLibrary(folder);
spContext.SetSaveStream(folder, stream, false, folder.ContentType, folder.Path + folder.Name + "|0x0120009BCC19899CEBC6468FF4EEAC7B8CF4F5"
spContext.SaveChanges();
So the important differences in the code above. The content type of the object and stream MUST be set to "Folder". I'm not sure why but you still need to set the save stream to be a valid stream even though you're only adding a folder. So just keep the stream
open and then pass "true" to close it when you actually save the file. The other important element as noted from the URL's in the previous comments is you need to add a "|" + Content Type ID of a folder. You'll be able to get this ID by visiting the rest service
for an existing document library and view source to see the actual content type id for a folder.
Thanks everyone for your help,
Damo

Sum Currency Fields using Workflow Field Update

Trying to have a workflow rule that updates a field "Total Payments" when any of the "Payment" amount fields change.
Created the workflow rule like this:
PRE('<cPayment1_ITAG>')<>[<cPayment1_ITAG>] OR PRE('<cPayment2_ITAG>')<>[<cPayment2_ITAG>] OR PRE('<cPayment3_ITAG>')<>[<cPayment3_ITAG>]
And the Update Field Value rule as follows:
=[<cPayment1_ITAG>]+[<cPayment2_ITAG>]+[<cPayment3_ITAG>]
But it doesn't want to work. Should I use "FieldValue" function for the update rule?
Thanks,
Dan

That worked perfectly, thanks Mani!
I've seen where people have mentioned using the "=" sign or no "=" sign but I'm not sure most people understand the proper use of when to use it versus when not to. Can anyone elaborate on the cases when an equal sign should be used versus when it shouldn't be used?
I personally would like to have a bit more knowledge regarding these types of idiosyncrasies of the syntax.

Listdata.svc - shows column names?

I have leveraged the REST service using listdata.svc many times. However, we are having trouble with one site in particular. Cannot use REST with it and getting all sorts of errors in Visual Studio. This post is not about VS or C#, however, just about
what should be in the REST schema period. I am seeing tons of huge node values when looking at the listdata.svc in a browser. It appears these are a combination of the list name and the column name. I didn't think column names showed up at all,
just list names?
For example:
<collection
href="InvestmentPortfolioAnticipatedProjectTeamSizeFTESContractorsCustomersVendorsEtc">
<atom:title>InvestmentPortfolioAnticipatedProjectTeamSizeFTESContractorsCustomersVendorsEtc</atom:title>
I found that Investment Portfolio is a legit list in the site, but the rest of that value is a column name. Other lists do not have columns listed in this schema when viewing from the browser. Can someone explain to me why this is happening?
Thanks

Hi,
If you access http://siteurl/_vti_bin/listdata.svc, the preceding url returns all the lists in XML format. There will be no column name included in a <collection> node for normal lists, except when
there is Choice column in this list.
There will be extra <collection> nodes listed as the format below for the lists which contains Choice column:
<collection href="ListnameColumnname">
<atom:title>ListnameColumnName</atom:title>
</collection>
It seems this extra <collection> node is for internally use only which is not designed to be exposed to developers.
I would suggest you submit a feedback to the Office Developer Platform if there any expectation about the documentation about SharePoint APIs:
http://officespdev.uservoice.com/
It is a place for customers provide feedback about Microsoft Office products. What’s more, if a feedback is high voted there by other customers, it will be promising that Microsoft Product Team will take it into consideration when designing the next version
in the future.

Can't get a delimiter between Reapting Table Fields using the Double Eval formula.

I have a problem in setting up the "Double Eval" formula, for a repeating table field.
Background:
I have a multiple-selection list box in an InforPath (2010) form. I want to concat all selected values in the list box and display them in a textbox with ";" as delimiter. I've gotten so far that with rules running when the list box is updated, the
textbox content is updated listing the IDs of the selected items (I'm not sure yet if I want to display the IDs or make a lookup for the true text values, but that's another issue for later...).
Problem:
My problem is that I can't get the delimiter between the values. They are all listed in sequence with the ";" delimiter only at the end.
I use the following formula ("Required" is the repeating field)
eval(eval(Required; 'concat(., ";")'); "..")
and get the following result:
What I want to get into the comments text box is the string "684;239;91;".
Any ideas what's wrong with my formula?
(Using InforPath 2010 on a list published to SharePoint 2010.)

Additional info that maybe is important to know:
The multiple-selection list box is getting its values from a secondary data connection using a web service call:
http://MySite/_vti_bin/ListData.svc/MyList?$filter=((CT%20eq%20'Product')%20and%20(CompGroup%20ne%20'OS'))&$orderby=Title
The selections in my list box is yet stored in the field "Required" in a different SharePoint list, we can call it "BaseList", at the same site ("MySite").
So to summerize:
List 1: MySite/MyList
Fields: CT, CompGroup, Title
List 2: MySite/BaseList
Fields: Required
The different lists have more fields of course, but no need to list them all.

Get all the field's value of addressbook entry using c++ api

How can i get all the field values of address book entry in groupwise using c++ api.

You should be able to do that via the Token API. There is an AddressBookGetEntry method. You could createsome sort of AddressbookEntry class that fetches (via iteration over the defined ABFields) all the innformation.

HT5624 Why in my email ( the one on my ipod5 that I use with my apple ID) when I get emails about my use of my apple ID to use a service in the from field it has my fathers name and when I click on it it shows his contact info ????

Why in my email ( the one on my ipod5 that I use with my apple ID) when I get emails about my use of my apple ID to use a service in the from field it has my fathers name and when I click on it it shows his contact info ???? I also set up my apple ID with a new email account and also I signed up for iCloud but used the same apple I'd email and password but it gave me a I cloud email! I did activate the favorites in my email . Noticed the from field has my fathers name and contact and it is a notification about me using my apple ID to sign in to FaceTime! Something is messed up, not sure how or why???

i didn't read a lot of your 2nd paragraph, but it seems like the password is the issue, right?
do a true clean install
reboot your machine and hold down command+option+r, you should see a spinning globe - if you don't see the globe or anything that reads internet recovery, shut down and try again
at menu, chose disk utility and once there, find your HD on the left side, select the physical name and erase it as mac journaled
exit disk utlity
at menu, choose install OSX
this time, when it asks for a password just hit continue, it will let you complete without a password
you should be able to get into your laptop, now figure out what password you'll be able to use with your kb issue

How to prevent a number field from getting summed?

I want to display the # of clients per a certain ID number. (In order to show the duplicate records by setting a filter in the # of clients field). However, this works if the ID number is a text field... but it doesn't work if the ID number is a metric of client... or number. It gets summed up, I get the total, and the % of clients turns to be 1.
Any ideas?
Thanks

Example:
I have 3 clients:
Column A
55
55
44
21
I want the following output:
55 | 2
I get the desired result by adding a second column (# of clients) and creating a filter to get results only if the value is > 2.
The problem is when "Column A" is a number field. If it is a number field, I get total sum of the records (55+55+44+21) and a value of "1" if I add the # of clients column.
Is it clearer now? ideas?

Http Bad Request when using /_vti_bin/listdata.svc in excel or tableau

hi all,
I followed a guide from tableau that teaches us how to connect odata(sharepoint list data) but it keeps giving me HTTP bad request.
When i tried to access my list using http://myserverIP/_vti_bin/ListData.svc
from the browser with credential, I am able to access the listdata and see the data from other lists. I decided to try connecting to excel instead but it gives me the same error, HTTP bad request. What am I doing wrong? Does the problem comes from
access rights or?
Can anyone help or guide me? Thank you

Thanks Tim,
That worked. Got rid of my error. However, if the field is null (=''), I get a total.

If the not null (!='') I am not getting a total.
