sharepoint list caml查询问题，因为它超出了阈值限制

Question

I am getting below error while querying SharePoint list,list has 5005 records and threshold limit is 5000. I have a sharepoint list having different folders and i am using CAML query with RecursiveAll to get records from all folders. I am getting this error :-

The attempted operation is prohibited because it exceeds the list view threshold enforced by the administrator. at Microsoft.SharePoint.Client.ClientRequest.ProcessResponseStream(Stream responseStream) at Microsoft.SharePoint.Client.ClientRequest.ProcessResponse() at

My query is

"<View Scope='RecursiveAll'> <RowLimit>1000</RowLimit><Query><Where><Eq><FieldRef Name='Year' /><Value Type='Text'>" + Period + "</Value></Eq></Where></Query></View>";

Year is indexed column.If i remove where clause,it starts working.It seems to me recursiveall is not working with where clause.

I don't want to change list threshold limit.

Answer 1

The default threshold for a list is 5000. You need to change the SharePoint Configuration settings for this list to have a higher threshold. Not sure what version of SharePoint you are on, but if you can access Central Admin here is an article explaining how to change it .

If you are using SharePoint Online, I think you might be stuck, but one of these answers has a supposed work around for it .

Answer 2

To overcome this issue, you will need to use the ContentIterator. Essentially you are breaking up the query in batches of eg 2000 items. From the Microsoft website:

SharePoint Server provides a new API, ContentIterator, to help with accessing more than 5,000 items in a large list without hitting a list throttling limit and receiving an SPQueryThrottleException. ContentIterator implements a callback pattern for segmenting the query for processing a single item at a time. Consider using this capability if you need to process a large number of items that may exceed a throttling limit. The following trivial example demonstrates the approach used with ContentIterator tested with a list returning 20,001 items from the query.

For official documentation, see here .
