How to get more than 1000 entities from an azure table storage query?

Question

I have read that azure table storage queries give maximum of 1000 entities and we have to make use of continuation tokens to fetch the next set of entities. I am just lookin

Answer 1

There are lots of ways to query table storage, but the easiest way is to create a CloudTable object, create a TableQuery object, then call ExecuteQuery on the CloudTable object passing in the TableQuery object.

The first result from http://www.bing.com/search?q=azure+table+storage+query&qs=n&form=QBRE&pq=azure+table+storage+query&sc=8-25&sp=-1&sk=&cvid=eb5a88d975df445ab665fbf5082fa7c8 will take you to http://www.windowsazure.com/en-us/develop/net/how-to-guides/table-services/ which shows examples of how to do this.

It's a bit grotesque - and not a great long term solution - but I forked the Azure Storage Driver for Linqpad specifically to get all records from table storage.

https://github.com/ryan1234/AzureStorageDriver

Get it, build it and install it with Linqpad. An example query that goes against it in Linqpad:

var logs = (from log in SBEmailWorkerRole.ToList()
            select new {
                LogEntry = log.LogEntry,
                CreateDate = log.Timestamp.ToLocalTime()
            }).ToList();

logs.OrderByDescending(l => l.CreateDate).Dump("Logs");

Answer 3

If my understanding of documents is correct, there is no way to do that.

Please be aware that continuation tokens can be returned even when number of records < 1000. It is a good idea to always check for continuation tokens when executing queires.

Also, why do you want to return more than 1000 records? what is the use case?

Using the AsTableServiceQuery like so:

var data = context.CreateQuery<SomeEntity>("table").AsTableServiceQuery<SomeEntity>().Execute();
