Trying to understand how the service broker works, through a hello
world type sample (TSQL's below).
A select on the target queue does not give back any results. Any
clues?

Regards,

Rohit

-- We will use adventure works as the sample database
USE AdventureWorks
GO
--ALTER DATABASE [AdventureWorks] SET ENABLE_BROKER
-- First, we need to create a message type. Note that our message type
is
-- very simple and allowed any type of content
CREATE MESSAGE TYPE HelloMessage
VALIDATION = NONE
GO
-- Once the message type has been created, we need to create a
contract
-- that specifies who can send what types of messages
CREATE CONTRACT HelloContract
(HelloMessage SENT BY INITIATOR)
GO
-- The communication is between two endpoints. Thus, we need two
queues to
-- hold messages
CREATE QUEUE SenderQueue

CREATE QUEUE ReceiverQueue
GO
-- Create the required services and bind them to be above created
queues
CREATE SERVICE Sender
 ON QUEUE SenderQueue

CREATE SERVICE Receiver
 ON QUEUE ReceiverQueue (HelloContract)
GO
-- At this point, we can begin the conversation between the two
services by
-- sending messages
DECLARE @conversationHandle UNIQUEIDENTIFIER
DECLARE @message NVARCHAR(100)

BEGIN
 BEGIN TRANSACTION;
 BEGIN DIALOG @conversationHandle
       FROM SERVICE Sender
       TO SERVICE 'Receiver'
       ON CONTRACT HelloContract
 -- Send a message on the conversation
 SET @message = N'Hello, World';
 SEND  ON CONVERSATION @conversationHandle
       MESSAGE TYPE HelloMessage (@message)
 COMMIT TRANSACTION
END
GO
select * from ReceiverQueue --This statement does not give back any
results
