I'm beginner in Azure, I have created a Stream Analytics Job in Windows Azure. Here I'm using two Inputs in job, one is type of **Event Hub** and another is type of **Blob Storage**.

Below is the SQL Query for ASA Job (To store output in SQL Database) :

```
SELECT
    IP.DeviceId
    , IP.CaptureTime
    , IP.Value
    , [TEST-SAJ-DEMO-BLOB-Input].[DataType] AS TempVal -- Blob Storage Input
INTO
    [Test-Output-Demo] -- SQL Table to store output
FROM
    [TEST-SAJ-DEMO-Input] IP -- Event Hub Input

```

Below is JSON data in my Blob storage container (Blob Storage Input [TEST-SAJ-DEMO-BLOB-Input])

```
{"DataType":"DEMO"}

```

Everything is working fine except **[TEST-SAJ-DEMO-BLOB-Input].[DataType]** returns null instead of string 'DEMO'.

All data sent by Event Hub Input is storing into sql table and their is no error in process.

Any help is appreciated ...
