Question

I am currently having problems calling a stored procedure async from within a insert-update-trigger. For this I m using the service broker.

--message type
CREATE MESSAGE TYPE [TheMessage] VALIDATION = NONE

--contract
CREATE CONTRACT [TheContract] ([TheMessage] SENT BY ANY);

--queue
CREATE QUEUE [TheQueue] WITH ACTIVATION
(STATUS = ON, MAX_QUEUE_READERS = 1,
PROCEDURE_NAME = TheStoreProcedure,
EXECUTE AS OWNER);

--service
CREATE SERVICE [TheService] ON QUEUE [TheQueue] ([TheContract]); 

Within the trigger:

DECLARE @Handle UNIQUEIDENTIFIER;

BEGIN DIALOG CONVERSATION @Handle
FROM SERVICE [TheService]
TO SERVICE 'TheService'
ON CONTRACT [TheContract]
WITH ENCRYPTION = OFF;

SEND ON CONVERSATION @Handle 
MESSAGE TYPE [TheMessage](N'some data');

Within the stored procedure:

DECLARE @Handle UNIQUEIDENTIFIER;
DECLARE @MessageType SYSNAME;

RECEIVE TOP (1)
@Handle = conversation_handle,
@MessageType = message_type_name
FROM [TheQueue];

IF(@Handle IS NOT NULL)

BEGIN

-- some statements

END

This setup doesn’t seem to work. The trigger does not throw any errors so I assume the message is queued. But the receive within the stored doesn’t seem to work. None of my statements are being executed.

Ok, thanks for your answers, I fixed it.

The problem was that the service broker was disabled..
