public System.Linq.IOrderedQueryable<Microsoft.Azure.Documents.DocumentCollection> CreateDocumentCollectionQuery (string databaseLink, Microsoft.Azure.Documents.Client.FeedOptions feedOptions = default);abstract member CreateDocumentCollectionQuery : string * Microsoft.Azure.Documents.Client.FeedOptions -> System.Linq.IOrderedQueryable<Microsoft.Azure.Documents.DocumentCollection>
override this.CreateDocumentCollectionQuery : string * Microsoft.Azure.Documents.Client.FeedOptions -> System.Linq.IOrderedQueryable<Microsoft.Azure.Documents.DocumentCollection>Public Function CreateDocumentCollectionQuery (databaseLink As String, Optional feedOptions As FeedOptions = Nothing) As IOrderedQueryable(Of DocumentCollection)Parameters
- databaseLink
- String
The link to the parent database resource.
- feedOptions
- FeedOptions
The options for processing the query result feed. For details, see FeedOptions
Returns
An IOrderedQueryable{DocumentCollection} that can evaluate the query with the provided SQL statement.
Implements
Examples
This example below queries for collections by id.
DocumentCollection collection = client.CreateDocumentCollectionQuery(databaseLink).Where(c => c.Id == "myColl").AsEnumerable().FirstOrDefault();
Remarks
Refer to https://docs.microsoft.com/azure/cosmos-db/sql-query-getting-started/ for syntax and examples. ReadDocumentCollectionAsync(Uri, RequestOptions) is recommended for single documentcollection look-up.
