Public MustOverride Function GetUserQueryIterator(Of T) (queryDefinition As QueryDefinition, Optional continuationToken As String = Nothing, Optional requestOptions As QueryRequestOptions = Nothing) As FeedIterator(Of T)

Type Parameters

T

Parameters

queryDefinition
QueryDefinition

The Cosmos SQL query definition.

continuationToken
String

(Optional) The continuation token in the Azure Cosmos DB service.

requestOptions
QueryRequestOptions

(Optional) The options for the user query request.

Returns

An iterator to go through the users

Examples

This create the type feed iterator for users with queryDefinition as input.

QueryDefinition queryDefinition = new QueryDefinition("SELECT * FROM c where c.status like @status")
    .WithParameter("@status", "start%");
using (FeedIterator<UserProperties> resultSet = this.cosmosDatabase.GetUserQueryIterator<UserProperties>(queryDefinition))
{
    while (feedIterator.HasMoreResults)
    {
        foreach (UserProperties properties in await feedIterator.ReadNextAsync())
        {
            Console.WriteLine(properties.Id);
        }
    }

Type Parameters

T

Parameters

queryText
String

The Cosmos SQL query text.

continuationToken
String

(Optional) The continuation token in the Azure Cosmos DB service.

requestOptions
QueryRequestOptions

(Optional) The options for the user query request.

Returns

An iterator to go through the users

Examples

  1. This create the type feed iterator for users with queryText as input,
string queryText = "SELECT * FROM c where c.status like 'start%'";
using (FeedIterator<UserProperties> HasMoreResults = this.cosmosDatabase.GetUserQueryIterator<UserProperties>(queryText))
{
    while (feedIterator.HasMoreResults)
    {
        FeedResponse<UserProperties> response = await feedIterator.ReadNextAsync();
        foreach (var user in response)
        {
            Console.WriteLine(user);
        }
    }
}
  1. This create the type feed iterator for users without queryText, retrieving all users.
using (FeedIterator<UserProperties> feedIterator = this.cosmosDatabase.GetUserQueryIterator<UserProperties>())
{
    while (feedIterator.HasMoreResults)
    {
        FeedResponse<UserProperties> response = await feedIterator.ReadNextAsync();
        foreach (var user in response)
        {
            Console.WriteLine(user);
        }
    }
