Sample for binding an Azure Function (v2) to an external Table Storage using CloudTable instead of IQueryable. Tested on Visual Studio Code 1.19.3 and .NET Core 2.0.5 on macOS.

{
    public class TabEntity : TableEntity
    {
        public Int32 rowX { get; set; }
        public Int32 rowY { get; set; }
        public Int32 rowZ { get; set; }
    }

    public static class HttpTrigger
    {
        [FunctionName("HttpTrigger")]
        public static HttpResponseMessage Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", Route = null)]HttpRequest req,
            [Table("sampletable")] CloudTable tab,
            TraceWriter log)
        {
            log.Info("Kicking off.");

            // Load data from TableStorage using CloudTable
            var querySegment = tab.ExecuteQuerySegmentedAsync(new TableQuery<TabEntity>(), null);
            StringContent responseContent = null;
            foreach (TabEntity item in querySegment.Result)
            {
                log.Info($"Data loaded: '{item.PartitionKey}' | '{item.RowKey}' | '{item.rowX}' | '{item.rowY}'");
                responseContent = new StringContent(JsonConvert.SerializeObject(item), Encoding.UTF8, "application/json");
            }

            log.Info("Done.");
            return new HttpResponseMessage(HttpStatusCode.OK){
                    Content = responseContent
            };
        }
    }
}

{
    "IsEncrypted": false,
    "Values": {
        "AzureWebJobsStorage": "DefaultEndpointsProtocol=https;AccountName=xyz;AccountKey=01234567890",
        "AzureWebJobsDashboard": ""
    }
}

You're assigning to responseContent inside the foreach loop. If I'm reading that correctly you're only sending the last row of the table, but doing the work to deserialize all rows. That was intentional?

@yzorg sorry for the late response. Your assumption is accurate. This is a very minimal example to demonstrate accessing TableStorage, so don't expect any serious functionality here :)

it was very useful for me. solved my problem. also tell how can I add condition in query like filter in this statement tab.ExecuteQuerySegmentedAsync(new TableQuery(), null);

Glad to hear it helped @Preeti1910! TableQuery supports "Builder Pattern"-Style Where clauses like so (Example taken from the official docs found here: var tableQuery = new TableQuery() .where('Name == ? or Name <= ?', 'Person1', 'Person2'); .or('Age >= ?', 18);
