Question

I am would like to display progress feedback for user while stored procedure is running (multiple setps). All sql code is in transaction so I am using a service broker to get a real time updates. Could you suggest what is wrong with code below as I am not getting any messages in my queue?
Is there a better way of doing it?

--queue
create queue myQueue

--service
create service myLogs
on queue myQueue ([http://schemas.microsoft.com/SQL/Notifications/PostEventNotification]);

--log handler
create event notification myLogHandler
on  server
for userconfigurable_0
to service 'myLogs', 'current database' ;

--message
EXEC master..sp_trace_generateevent @event_class = 82, @userinfo = N'test msg'

---transaction test
begin transaction
EXEC master..sp_trace_generateevent @event_class = 82, @userinfo = N'tran test msg'
rollback transaction


--receive message
declare @message_body  xml;  
receive  top (1) @message_body = message_body
from myQueue
select @message_body

--display queue  
select * from myQueue

Answer 1

That works fine for me though I needed to wait a few moments and run the receive from queue bit again before I saw anything.

Perhaps you need to ENABLE_BROKER on the database.

ALTER DATABASE YourDB SET  ENABLE_BROKER WITH  ROLLBACK IMMEDIATE

(Warning: Will kill existing connections to the DB)
